General Questions

How can I tell if my home needs new insulation?

Your home may need new insulation if you notice some rooms are colder or warmer than others, or you can feel drafts around outlets, baseboards, or door frames.

The quickest way you’d notice the need for new insulation is rising heating and electrical costs.

What is R-value?

R-value is the thermal resistance of a material to heat flow.

Essentially, R-valve is how much heat or cooling can move through a material. The higher the R-value number, less energy is required to heat or cool a space. Saving you money on utility bills.

What is a vapour barrier?

A vapour barrier is a plastic sheeting that stops the transfer of moisture into your home from outside walls, floors, or ceilings. This stops the growth of mold or mildew that may cause reduced air quality in your home.

Spray Foam Insulation

Can I install spray foam insulation myself?

No, it is not recommended that you install spray foam yourself. Poly Plus Insulators has a team of certified spray foam installers. In Saskatoon and area, certified installers are required to spray polyurethane foam. This is mandated by the Building Standards department who requires the installer’s certification number for verification.

Becoming certified as a spray foam installer requires passing both a written and practical exam as a registered apprentice. This is no easy feat. Our certification lasts for five years, after which we must undergo further testing to maintain our certification. This ensures that we stay current and knowledgeable in our field.

As certified installers, we strictly adhere to the product manufacturer’s application standards and installation guidelines. Trust us to do the job right the first time around.

Does spray foam insulation need a vapour barrier?

Our spray foam does not need a vapour barrier since the foam itself functions as a vapour barrier.

What is the difference between Open Cell and Closed Cell spray foam?

Open cell spray foam expands more when applied, meaning it can reach hard to reach nooks and crannies in a space. As well, open cell provides a level of soundproofing to a home.

Closed cell spray foam acts as a vapour barrier, creating a tighter seal against water and moisture from outside. The rigid nature of closed cell also adds structural rigidity to a home.
