Expanding spray foam benefits

Learn the benefits of installing expanding spray foam insulation in your home or business property.

Have you really thought about if you have the most efficient insulation for you home? Truly, when you have the best insulation system for your home, it is a crucial factor in making sure you keep those agonizing bills low by creating a block and having all the conditioned air in your home stay in and not get out and vice versa. There are various ways to achieve this, but the explosion of expansion foam is certainly happening for a reason.

To fully understand the concept, expanding foam does exactly that, it expands and then hardens or ‘cures’ when it comes into contact with the air. When it does cure after it’s expanded and filled the space it was applied to, it hardens and blocks air from passing through it. Often it comes in DYI canisters that have the material compressed, you can attach a nozzle where it sprays out of. This system has surpassed all traditional methods of insulation such as fibreglass.

This material is generally composed of a two material mixture, a poly resin and an isocyanate. When this is sprayed into wall cavities, holes drilled into a wall, slabs of concrete or roof tiles, it creates a fantastic air tight insulating layer. The way it works is it traps microscopic gas bubbles in the foam. A major contributing factor to it’s superior insulating ability is it’s low density.

When the material is sprayed out of the nozzle, it is directly injected into every nook and cranny that exists within the wall or roof. Due to the high pressure, it is literally pushed into every space that is within the cavity it’s being injected in, where it will completely seal off every hole. When all holes are filled, it will then come out the entrance hole in the shape of spaghetti. When these noodle shaped pieces of the material exit the hole, that’s when you know that there is a proper seal. The excess material is then scraped off and the whole is filled with a mortar of sorts.

Research shows that a forty percent  loss of energy through air loss out of various spaces. When you properly insulate , air leakage will minimize and ultimately save you money. There is a much higher degree of air sealing ability in expanding foam compared to traditional insulations.

benefits and advantages of using expanding spray foam insulation


  • Simple to instal- the simplicity of installing this insulation is another benefit. Just spray the material into the hole that you need insulated. There is no need to measure anything, no cutting or gluing is involved.
  • Adheres to surfaces- this material is in liquid form and therefore covers more ground so to speak. When it is sprayed and sticks to the surface it the expands to fill any spaces.
  • Extremely durable- unlike other types of insulations, expanding foam is extremely durable. It doesn’t rot and wicks moisture away. It is also inhospitable to insects and rodents that can cause further damage.
  • Climactically suitable anywhere- this material will fair well in any climactic region of the world. Traditional insulations usually have a weakness in moist climates as they can retain moisture and develop mould . Expanding foam insulation however avoids any of these situations as it is a repeller of moisture.
  • Efficient blocker of Heat transfer- this material will block heat from transferring three different ways 1. Convective where air is the main transferring way, 2. Conductive, this is when there is a flow from a lower temperature to a higher or vice versa, 3. Radiant which is when heat is in the form of light emitting from warm surfaces.
  • Saves money- expanding foam is so good at blocking air transfer that it will immediately slash your energy bills by a staggering %40.
  • Sound dampener- a by-product of using expanding foam insulation is that it will behave as a noise reducer as well. Sound travels in vibrations, and if you disrupt that vibration with expanding foam insulation you’ll have a quieter space.
  • Air quality improvement- it will improve the quality of air as it keeps spores, germs and pollens out.

Avoid ice dams forming on your roof with spray foam insulation

How the ice dams formulate

When you live in a climate that has sub-zero temperatures during the winter months, then your homes insulation is something that isn’t taken lightly. Truthfully though, a home that is properly insulated isn’t only an indicator of a warmer home, but has benefits that reach further into other areas of a safety and also economic.

As kids, you may have been in awe of homes that had large and long icicles that were hanging off of the eaves drops. Sadly, these spectacles of nature are more often than not a result of a dangerous problem looming inside the roof of the home. There are solutions to having these ice dams from forming. What is the solution to this problem? Well lets have a look at the complete picture to get an idea.

learn how to avoid ice dams building up on your roof in Toronto

If an attic isn’t sufficiently insulated, or improperly, warm conditioned air seeps through gaps that are between the insulation of the homes ceiling and the attics floor. In effect, the heated air can melt the snow that has rested on the roof of the home. Naturally, this will create a runoff from the roof. When this runoff ultimately reaches the colder eavesdrop, it can freeze up again and hence lead to an ice dam development. This process repeats itself until a noticeable buildup occurs and and ice dam then backs up further up the roof, this can sometimes devastate shingles and peel them off the roof. At this point the roof is now susceptible as it’s shingle membrane has been compromised, so all of the melting of the snow and its water runoff have nowhere to go but into your home.

The ice dam consequences

There are a few problems that can come to pass as a consequence of the formulation of ice dams on your roof, of which many can be serious:

  • ice buildup can cause damage to eavestrough
  • water can penetrate your roof and damage walls and ceilings
  • if you have traditional insulation, it can get wet and lose it’s R-value
  • mildew and mold can develop dangerously on moist insulation
  • shingles can dislodge
  • icicles can injure someone if they fall
  • ice buildup can lead to shingle damage

The telltale sign that your roof may be in jeopardy are the formation of icicles on your eaves. Check out our flat roof insulation service for homes in the GTA here:

Temporary fixes for ice dams

If old man winter has already rolled in and you just begin to notice that you are at risk of your roof developing ice dams, there are several solutions you can opt for to help with the management of future problems arising. Though none of these are permanent solutions, they can help you get through the winter at hand whilst minimizing damage.

Avoid climbing up a ladder to try and chip at the ice with an ice pic or shovel, this is extremely dangerous as the conditions can be slippery, it can also potentially damage the shingles and the eaves on your roof.

A good temporary solution would be to use calcium chloride to help melt away the ice that is in the passageway, this way the water has a place to drain away into and not keep building on existing ice. An efficient way of distributing this is to take an old article of clothing and fill a sleeve with the calcium chloride, place it on the roof vertically. What this does is it creates a trough where any melting ice can safely pass through.

Furthermore, another temporary fix if there is a leak, is to bring in a high-powered cooling fan into the attic and freeze the area where this water I leaking into. What this does is it keeps the water in ice state limiting water damage until spring comes around and a more permanent solution is available.

Permanent solutions for ice dams

Truthfully the above mentioned temporary solutions are only short term and they will only ease the damage done for that season. Some people may have all the answers , but there’s only one way that you can minimize the formation of ice dams permanently, and that’s by creating the same temperature on your roof as the outdoor air.

The proper way to achieve this is to insulate your attic properly, and of course to get the best seal to avoid any leaks that would melt the snow and create this potential hazard. How is the best way to achieve this air seal? With spray foam insulation.

A major difference from spray foam insulation and traditional insulation, is that air leaks are difficult to avoid with traditional as it is difficult to get a solid seal in hard to reach nooks. Spray foam insulation on the other hand has an expanding nature that happens when it is applied and it fills all the nooks and crannies that would otherwise be impossible to seal. This creates the most airtight seal in the business.

The heat generated by your homes heating system will stay where it is meant to when you use spray foam insulation, and you will drastically minimize the risk of an ice dam forming as an attic sealed and insulated with spray foam has little to no air loss. This will ultimately leaving you to enjoy your homes comfort while not having to worry about any damage occurring on your roof which can lead to other hazards.

Spray foam insulation for cottages in Ontario

Winterizing your cottage with spray foam insulation

Classic cottages in Ontario are rarely properly insulated and have little if any. Generally the climate allows for this as most cottage goers enjoy the cottage during the summer months where insulation isn’t necessary, as the warmer weather doesn’t create moisture inside and the structure keeps a dry atmosphere. The problem is that some people opt to enjoy their cottage during the winter months as well, and create a winter getaway. To achieve this, there is no way around it, the cottage has to be insulated. Just like your home in the city, insulating the cottage will create a comfortable indoor environment from season to season, and it will manage the moisture.

best spray foam for cottages

To properly winterize the cottage, it will take a methodical approach that entails insulating and sealing, this is the only way to optimize efficiency and comfort in the structure. After insulating, plumbing pipes will not freeze and burst, doors and windows not need shuttering during the winter, and appliances will be usable throughout the year. This will make your cottage fully ready throughout the year.

The majority of cottages have air leakage problems and they usually leak through the roof cavity and exterior walls. Generally speaking most walls and roofs are neither properly insulated or sealed from drafts. If professionals are brought to task, they will almost always recommend a proper seal be done first. This will allow for the proper control of air vapour/moisture accumulation and air movement. After the seal follows with a high grade insulating product the will bring the R-value where it should be for the climactic character in the region the cottage is located .


Your cottage can be in various degrees of conditions, however there usually is a required removal of insulation that is there. They are probably underperforming materials and in many situations actually deteriorating. Outdated insulation is often a liability to airflow and hinders proper air circulation. The best route to take of course is to re-insulate from scratch, especially a roof cavity. This will allow for the best air sealing an proper installation of a new insulating material. Additionally, any repairs that were once a big job are now easily accessible as you will be exposing wires and plumbing and generally the bare bones of the structure. Old insulation has to be done right from the get go, doing it through and expert will ensure a proper, safe and clean job while creating a proper installation of the new material that will bring years of comfort to the space.


When done correct, attic insulation can significantly reduce the cost of heating in the winter months while creating an ideal indoor temperature and atmosphere. No matter the season, attic insulation will create an indoor atmosphere that will balance both air moisture and temperature leaving the space more comfortable. A properly sealed attic is crucial to avoid any air leakage. Properly sealed, a space will use far less energy and ultimately reduce bills and save you money. Generally this will slash the winter bills , however this can also have positive effects during the summer months as well as it will help with air conditioning. The high quality insulation that will be installed will offer the proper thermal protection for harsh winter environments, as well as air circulation optimization.


A cottages unique needs can be met with spray foam insulation, as it is an ideal air sealer and insulator. It is the best insulating material is it is the king of getting into all nooks and crannies to avoid any major air leakage, effectively sealing roofs, walls and everything in between that would allow for air flow. It can also present solutions for weatherproofing windows and doors where air leakage poses a significant problem. Most professionals will admit that spray foam is a far more advantageous product on the market when it comes to insulation. If expertly installed you can benefit several ways: moisture control; air leakage will be stopped; R-value can be achieved far better than any other product out there. Spray foam is the ultimate solution for winterizing a cottage, as it will outperform all other materials, as well it is maintenance free an won’t ever need replacing in your lifetime

What is closed cell foam insulation ?

They type of foam insulation you should use.

Good on you for choosing to take your homes efficiency to the next lever and deciding to go with spray foam insulation. As you embark on researching this hot topic, you’ll find out that there are generally two types of spray foam that you can go with: closed cell and open cell. Which you decide to go with will depend on what your situation is and more specifically what area you want sprayed and what your budget is like. Read further to get a better understanding on the difference between them.

learn about closed and open cell spray foam


The cheapest of the two spray foam insulations on the market, open celled spray foam gets its “open” from the cells that created the matrix of the foam. After the foam is sprayed and it expands, these open cells then trap air after it hardens and it then behaves as an insulator.

Open cell spray foam is more flexible than closed cell and this is because it is much softer than the closed cell. It’s a superior product for areas that require less insulations, and for surfaces that experience frequent temperature fluctuations. This type of foam insulation averages at around R 3.5 per inch as an insulating value.

It’s good to note that due to the open nature of the foam cells, this foam is penetrable by water, though it does create and air seal. Because of this characteristic, it is good to make a note that this foam solution shouldn’t be used as a vapour barrier.


Open cell and closed cell insulation share the similarity that they are both consisted of cells that are densely packed together. The difference is that closed cell foam is exactly that “closed” and has gas trapped in these cells. It is this trapped gabs that behaves like an insulator. This has a higher R value than air, and it raises the this foams R-value to an R-7 per inch.

Also, closed cell spray foam is more rigid and it doesn’t allow for the passage of moisture which allows for it to double as a vapour barrier. It can also be used as a structural reinforcer. It is ideal for areas that need extra insulation value, as well as protections for moisture. Roofs, exterior walls and attics are all perfect places to use this particular foam.

Both of these insulations have revolutionized the insulation world. You can purchase DIY kits, however it is recommended to go with a professional reputable company, as it does require a finesse to apply it properly.

Commercial building spray foam insulation

What is considered a commercial building ?

While building codes vary from municipality to municipality, generally speaking anything over three family dwellings can be considered a commercial building. Even though residential and commercial construction have different insulation requirements, the idea is exactly the same: safe and comfortable to occupy through proper insulation and air sealing, all while being economical. The higher the R-value, the less outside air can penetrate the insulation. This is a fact and doesn’t change no matter the construction method.

Sadly, the code doesn’t really talk about the air sealing. At www.sprayfoamkings.com we know all too well what this will entail, and rightfully so we take extra care to air seal all of the projects we work on. The truth is spray foam insulation thankfully behaves as an air sealant as well as an insulation all in one.

There are various types of commercial buildings. From schools to churches and much more, they come in all sizes and have different styles of construction. Generally, we will have a look at masonry, wood and metal construction, as well as sound dampening as another characteristic of the spray foam insulation.

commercial spray foam contractors


It is a very popular construction material in commercial buildings, structural stele or light gauge from, metal has some challenges when it comes to insulation due to its conductivity. If there isn’t an exterior insulation that is seamless layer, the metal conducts cold air into the structure in massive amounts. This of course will affect the R-value of the wall negatively, as the true r-value is now compromised no matter what the value of the insulation in the cavity is. And it doesn’t stop there, the cold metal can create a freezing and condensing effect of moisture that is in the air, either on drywall or the inside of the wall. Metal building construction should never have a penetrable insulation used like fibreglass, as this condensation can happen and wreak havoc. Vinyl covered insulation will allow for moist air to come in contact with the metal and it will freeze as it condenses in frigid temperatures. This is where the ideal characteristics of closed cell spray foam insulation will bring both vapour barrier and insulating effects to the table making it an ideal choice for this type of application.


It’s the size by which commercial wooden framed buildings can separate themselves from a residential building. There is little difference when considering insulation and air sealing in the buildings, but the potential hazard is much greater if there is a system failure, for example if a pipe happens to burst due to drafts in a floor it would be significantly worse if it took place on an upper level of a nursing home.


To provide any sort of comfort, all concrete, block and brick walls must be insulated. When in new construction, by far the best at this task is spray foam insulation, and it would have to be installed either behind the drywall, or on the outside of the structural wall. In any case, there should be an unobstructed layer of foam , so it is vital to leave space between the masonry and the framing for the spray foam. It is also possible to fill cavities for a retrofit scenario.

Spray foam insulation for flat roofs in Toronto

Flat roof sprayed polyurethane foam insulation

Ever since flat roofs were invented, they’ve proven to be intimidating to both homeowner and contractor alike. They have multiple difficulties including maintenance, waterproofing and insulating. We will be discussing the insulating problems for now.

You must be very careful with which method and materials you use, to successfully insulate a flat roof. Here is a breakdown of how things should be organized:

Ceiling Insulation

Going this route isn’t recommended as it would cause the height of the ceiling to drop 4-5 inches so that it would meet local codes. This would additionally make any future hardware or lighting upgrades very difficult to instal.

best foam insulation service for flat roofs in Toronto Ontario

Getting Between the Ceiling Rafters Insulated

Only two insulation types should be used for this way of doing it. Dense pack cellulose insulation, or some open or closed cell spray foam insulation. Because air doesn’t really move in a straight line, it makes it very hard to properly ventilate a flat roof which is why these are the only two recommended materials to use. This would promote moisture to come into that area and if trapped, would wreak havoc and be very difficult to remove. It would save a great deal of headaches to have an area that wasn’t ventilated and to just spray the area with 4-5 inches of spray foam, or fill the whole cavity with dense pack cellulose.

It’s important for you to consider stud height, if there are existing 2×6 studs, you’ll be limited to using closed cell spray foam insulation (which isn’t really a limit) due to  the restrictions in R-value. Cellulose is R-3.8 per inch, open cell foam is R-3.5 per inch and closed cell foam is R-6 per inch. If there are 2×8 studs, then you can also use open cell spray foam or dense pack cellulose.

One thing to note, is that fiberglass insulation should in no circumstance be used for such and application. Dense pack cellulose insulation will run you $1.50 per square foot, open cell spray foam will run you about $3.25 a square foot, and closed spray foam will take it to $6.00 per square foot. To learn more about the costs involved with foam insulation both on the flat roof and at your home or commercial property contact Spray Foam Kings today.

Installing Insulation On The Outside Of the Roof Surface

This method is the most commonly used method in commercial flat roofs, but can also be used for residential as well. It’s done by using a powerful adhesive and applying it to the foam board, spreading it on the roof area, and fastening it with washer head nails. The waterproof rubber membrane will then adhere to the foam board. To achieve the required R-value, it normally takes two or more layers of foam board. This method requires no ventilation, the spaces between the ceiling joists can stay empty as they are. Keep in mind that when going with this approach, rim joists must be insulated to keep the whole system integral from roof to walls as to steer clear of moisture issues down the road.

Batting vs Spray Foam Insulation in Toronto

Batting or spray foam insulation – what to use?

Winters in the GTA mean that many homeowners are concerned with cold drafts in their homes due to poor insulation, and our of control heating bills which again are due to poor insulation. Insulation is a topic that Canadians are all to familiar with as we do have extreme temperature fluctuations throughout the year (our roads are a testament to this exact phenomena). Over the years, we’ve been seeing the rise of spray foam insulation, where most people growing up know the fibreglass batting as the most common insulating material. The question is, which one is better? And which one do you choose?

what are the best choices between spray foam and batting insulation

Both spray foam and batting insulation come with their pros and their cons. Here is a brief run-through of what to look for.

COST – the major difference between batting and spray foam insulation, is the price and complexity of installation. Spray foam insulation to be installed properly will require a professional, whereas batting can be a DIY project. Because of this added labour/expertise, spray foam insulation can be up to two or three time more expensive than batting.

STRUCTURAL AND AIR QUALITY CONSIDERATIONS – a major benefit to spray foam is that it’s ability to create such a good air tight seal comes with more benefits to your home other than just insulation. Once cured, the foam acts as another level of structural reinforcement. to add to this, it significantly improves air quality inside as it blocks any pollutants from entering as it blocks heat from escaping, in the same manner allergens are also blocked from entering your home.

ENVIRONMENTAL- Low in volatile organic compounds or VOC’s, spray foam is a green product that has massive growth for our ever renewable/greener future. Batting can have some environmentally friendly variations, it isn’t as versatile and there isn’t as much room for growth in the area spray foam does.

LENGTH OF LIFE- batting as we all know does begin to break down and become less and less effective as an insulating material over time. Spray foam however is literally everlasting and will probably outlive the home! Unlike batting, spray foam will maintain it’s insulation properties throughout it’s life. Batting starts to sag and air pockets form, if it gets wet, it is rendered useless as an insulator. Spray foam insulation has water repelling properties and would maintain its integrity even if wet.

QUALITY OF INSULATION- spray foam has multiple benefits, but it’s ability to insulate is unsurpassed. It creates a thermal envelope in your home which is very hard for any conditioned air to be displaced through it. The quality of the material coupled with the installation from a professional will ensure that your insulation is the best possible insulation out there, and can not be replicated with any other material.

It’s seen a surge in the construction world and with good reason. Spray foam insulation has multiple applications and it is going to continue to grow in the field of construction for years to come. The quality of insulation and water/fire resistant character means that it is a multifunctional material that does not only it’s job, but other requirements without the need to use other materials. Spray foam insulation is the insulation of the future.
