Spray Foam Insulation

Spray Foam Insulation



(The Icynene Insulation System)



Icynene Spray Foam Insulation Products



The Icynene Spray Foam Insulation System is a series of soft, flexible spray foam insulation products that delivers up to 50% greater energy savings when compared to other insulation products. Icynene is perfect for loft insulation, cavity wall insulation, dry lining insulation, sound insulation and more.



When sprayed in place Icynene expands completely filling all cavities and voids creating a sealed building envelope which eliminates air leakage/infiltration. Air leakage/infiltration accounts for up to 50% of heat loss from a building. Unlike other foams, Icynene’s unique polyicynene formulation is 100% water blown and therefore contains no harmful agents, volatile organic chemicals, HCFCs, HFAs, HFCs or formaldehyde.



Icynene is the only foam on the market successfully tested and certified for applications directly to the underside of breathable and non breathable roof membranes and felts and recently received BBA certification for this application. Icynene absorbs the lowest amount of moisture and has the highest level of vapour resistivity of any soft foam on the market.

Homeowner Benefits



The insulation in your home can impact many areas of your life.



Save Money



Icynene spray foam insulation is a premium product that pays for itself quickly.



Save on energy bills – Icynene spray foam insulation can help you save on heating and cooling costs by up to 50%. By providing U-value insulation as well as air sealing, it cuts your home’s energy loss.



Reduce heating and A/C size – You may be able to reduce the size of your heating and cooling equipment, saving installation or replacements costs.



Get better payback & resale – Investing in insulation that can create an air barrier and minimize random air leaks can deliver fast payback, and buyers may be willing to pay more for a home with lower energy costs.

Be Healthy



By air sealing your home, you can help block pollutants that can affect your health.



Reduce dangers of respiratory distress – allergies, asthma, and certain chemical sensitivities can be caused by natural airborne irritants.



Minimize pollutants – dust and dirt, mould and moisture, radon, exhaust fumes, and carbon monoxide are reduced by air sealing, to keep your home and air clean.



Protect against mould growth – minimizing the flow of random airborne moisture entering your home help you protect against mould growth that may lead to conditions such as asthma and allergies and cause symptoms such as itchy eyes, sneezing, and coughing.


Be Comfortable



  • Air sealing your home using Icynene spray foam insulation creates a cocoon effect, increasing the comfort of your home.



  • Reduce drafts – a home without spray foam insulation loses enough air each day to fill two blimps.



  • Avoid hot and cold spots – seal between heated/cooled living spaces and unconditioned spaces such as garages and basements, to maintain even temperatures throughout your home.



  • Reduce noise – Icynene open-cell spray foam can help reduce sound from noisy indoor rooms such as media rooms and laundry rooms, outdoor noises such as traffic and playgrounds, and transferred noise such as flushing toilets.



Protect Your Home



You want your home to last a long time – Icynene spray foam insulation can help.



l  Protect against moisture – 99% of the moisture that enters the walls of your home is carried in the air. You can reduce the amount of moisture that gets into your home, and the mould and moisture damage that can come from it, by air sealing it with Icynene spray foam insulation.



l  Keep pests out – Icynene spray foam insulation does not provide a source of food for rodents, termites, or other nasty critters. It also doesn’t make for good nests, and as a solid material it’s difficult to pass through, helping protect your home from critters.



l  Structural Integrity – Depending on your application, and the product you choose, Icynene can offer extra structural stability to your walls which can’t be achieved using other traditional forms of insulation.




Icynene Spray Foam Stops Air Leakage



  • Spray foam insulation is like a warm wind breaker jacket – it stops the cold air from passing through.



  • Fibreglass and cellulose insulation are like a wool sweater – if there’s any breeze, it doesn’t keep you warm. Even if they’re very thick to give an extremely high R-value, they’ll still let air leak out and increase your energy bill.



Spray Foam is a Modern Material



  • Spray foam insulation is a modern material that’s been used for over 25 years.



  • Fibreglass is an old technology, and cellulose is little more than shredded newspaper. So modern types of insulation are becoming more popular.



Spray Foam Fills Gaps


  • Spray foam insulation expands up to 100 times to fill gaps – ensuring maximum insulation.




  • Fibreglass and cellulose are extremely difficult to install perfectly – the spaces that are left add up to the size of a basketball in the average home – leaking enough air to fill two blimps each day!



  • Icynene Spray Foam Protects Your Home From Water



  • Many open cell spray foam (such as Icynene LD-C-50) drains water rather than holding it, and most closed cell spray foam doesn’t let it in at all.



  • Cellulose is made from shredded newspaper, and drinks up water. Fiberglass batts and cellulose don’t repel water – the water stays in place and may damage your building as well as reducing how well the insulation works. This is one of the leading contributors to mould development – and it also decreases R-values, meaning you spend more on energy.




Spray Foam Stays in Place



  • Spray foam stays in place – it doesn’t settle or sag, vertically or horizontally. It moves with the house as it settles. Spray foam insulation is completely solid when it sets, doesn’t produce any dust, and doesn’t let dust or other pollutants pass through to your home.



  • Fibreglass and cellulose settle and sag over time, leaving gaps that compromise insulation.



  • Fibreglass and cellulose can be dusty and allow dust and other pollutants to enter the building.



Icynene Spray Foam is Healthier



  • Many spray foams (such as Icynene LD-C-50) don’t contain formaldehyde, HCFCs, HFAs, or HFCs, and doesn’t give off harmful emissions once installed.



  • Most fibreglass contains formaldehyde, and may emit formaldehyde fumes into your home.




Spray Foam Doesn’t Attract Pests



  • Many spray foams do not provide a source of food for rodents, termites, or other nasty critters. It also prevents birds from making nests.



  • Fiberglass and cellulose can be torn apart by pests, and some even use them for nesting.



  • Spray foams structure makes it very hard to damage



  • Spray foams harden to a dense material that isn’t easily damaged.



  • Exposed fibreglass and cellulose are easily damaged – insulation in areas such as basements and attics may be compromised by cats, children, moving boxes around, and other general usage




10 Questions to Ask



Choosing Which Insulation To Use: 10 Questions to Ask



Insulation is one of the top 10 design choices you’ll make in your new home. You should feel free to challenge your home builder with good questions to make sure you’ve got the right product for your home.



1    How well does the insulation control air leakage that can account for up to 50% of a home’s energy loss?



2    Can the insulation create an air barrier without the use of extra finishing materials (tape, gaskets, plastic wrap) and labour?



3    How quickly will the insulation pay for itself? Could the monthly savings outweigh the monthly cost of financing?



4    How does the insulation compare in reducing air leakage in hard-to-insulate areas, such as basement rim joists, cathedral ceilings, crawlspaces, and garages, without extra materials?



5    Can the insulation help reduce the required size and cost of your furnace or air conditioning unit?



6    Will the insulation improve the air quality in your home by minimizing air infiltration to help keep out allergens, dust and other outdoor pollutants?



7    Can the insulation shift with the home as it settles and lose its U-value?



8    What happens if the insulation gets wet?  (How well will the insulation dry out, e.g. after a roof leak? Will it keep its insulating properties through the wetting and drying process? Is it a food source for mould?)



9    Does the insulation contribute to a “greener” home?  (Total reduction in energy consumption, overall use of other building materials, indoor air quality?)



10 Can the insulation help make your home quieter, suppressing plumbing, between-room, and street noise?
