TOP SPRAY FOAM QUESTIONS AND BEST ANSWERS

Recently, spray foam insulation is becoming very popular. Because of its high energy efficiency, many Canadian homeowners are starting to gain interest. Compared to last year, its usage has increased for 40%. To decide the most adequate insulation for your home, it’s always recommended that you consult with qualified insulation companies in Toronto. In the meantime, here are some answers to the top 10 questions about Toronto’s most popular material – spray foam:

WHAT IS R-VALUE?

To make things easier for homeowners, experts introduced energy efficiency ratings. From windows and doors to insulation, these ratings inform buyers about the product’s quality. R-value is one of the most important ones, standing for a material’s ability to resist heat loss. Homes that have insulation with high R-values are well insulated and more efficient. As a modern material, spray foam insulation has the highest ratings on the market, ranked at R-6.

SHOULD I USE OPEN OR CLOSED CELL INSULATION?

This question is very common amongst homeowners and there is no “right” answer. Truth is, everything depends on your situation. Closed cell spray foam is better for difficult climates since it is moisture and fire-resistant. On the other hand, open cell insulation expands more, being more adequate for hard-to-reach areas and nooks. It’s also better at soundproofing and is more cost-effective. 

DOES SPRAY FOAM NEED A VAPOR BARRIER?

Vapor barriers are used to strengthen water-resistance. Technically, all insulation is a vapor barrier, but sometimes it needs help from other materials such as tarp. Since it is highly moisture-resistant, closed cell insulation doesn’t require a vapor barrier. However, vapor barriers on open cell spray foam are sometimes even required by law and building codes.  

SHOULD I LEAVE THE HOUSE AFTER SPRAY FOAM APPLICATION?

Many people believe that spray foam is health-hazardous. Yes, during the application process, spray foam insulation contractors always wear protective masks and gloves. But, the material is safe to be around just after 24 hours. You should vacate your home the first day, but afterwards is completely safe to get back.  

CAN I USE SPRAY FOAM FOR ATTIC AND CRAWLSPACE INSULATION?

High R-values prevent temperature loss, avoiding mold growth, dampness and rot. Since spray foam has high R-values, it’s extremely beneficial in rooms prone to excessive moisture like attics and crawlspaces. Have in mind though, each home is different, so contact insulation companies to get the right estimates and solutions.

CAN I USE SPRAY FOAM FOR JOIST POCKETS?

Regular insulators like fiberglass and cellulose aren’t that effective in joist pockets (also known as joist cavities). Whether open or closed cell, spray foam insulation contractors in Toronto manage to fill all the cracks and smaller voids. This makes it perfect for joist pockets. Additionally, its moisture-resistance will prevent all kind of damages such as mold growth and rot. 

WHAT OTHER SURFACES ARE SPRAY FOAM-FRIENDLY?

It’s no coincidence spray foam is so popular with modern homeowners. It can be installed literally everywhere, including on wood, concrete, plywood, cinder, block, and brick. The only thing that must be avoided are greasy and oily areas that can immensely complicate and disrupt the application process. 

WILL IT IMPROVE SOUNDPROOFING IN THE HOUSE?

Insulation contractors in Toronto speak highly of the soundproofing qualities spray foam provides. Highly noise absorbent spray foam, especially open cell, is ideal the ideal sound attenuator, even for hard-to-reach areas and irregular surfaces. With it, exterior noise remains blocked while interior is safely kept inside.

DOES IT COME WITH WARRANTIES?

When doing a home remodel or repair, always ask for warranties. These guarantee for both the quality of product and labor work. The warranty types differentiate based on the product, project, and company you choose. In any case, the spray foam should be covered from 15 to 30 years, also being transferable to the next owners if you plan to sell. Additionally, the best foam insulation companies in Toronto offer 1 year workmanship warranties.

WHAT IS CUFCA?

CUFCA is an acronym for Canadian Urethane Foam Contractors Association. This is where all the spray foam insulation contractors get there certificates and accreditations from. Insulation contractors in Toronto are usually trained by the highest industry standards, but always make sure to ask whether they are approved and certified by the renowned CUFCA.
