What is R-value?

R-values and their metric equivalent, RSI values, are a way of labeling the effectiveness of insulating materials based on the resistance the material has to heat transferring through it. Common insulation product thicknesses and the R-values can vary.

Ultimately, the effectiveness of the insulation is reliant on how it is installed. If installed incorrectly the R-value can be reduced making the insulation product ineffective.


What does spray foam insulation cost?

We’re not going to hide the fact that professional polyurethane foam is more expensive than generic pink insulation.

However, you will see a return on your investment within 5 to 10 years with heating and cooling costs being reduced by up to 50%.

Can I install spray foam insulation myself?

Only trained, certified, and licensed installers should install spray foam insulation into buildings.

When you hire a company that is certified and whose sprayers are properly trained and licensed, you are ensuring safe, professional, and consistent installations. Trinity’s installers are trained, certified, and licensed through CUFCA who use the SPF Quality Assurance Program.


Do I require ventilation in my attic?

One of our certified estimators will assess the need for ventilation during a free site visit.

Ultimately, ventilation is very healthy for your attic space. The temperature in the attic should be equal to the outside. Ventilation helps to avoid condensation build up, moisture damage, and ice damming.


How will you insulate my exterior walls without removing my drywall?

Blown in cellulose insulation is a fantastic option for insulating exterior walls. Cellulose is extremely environmentally friendly and made with 100% post-consumer recycled newsprint.

We are able to insulate your walls with minimal adjustments regardless if you have vinyl siding, cedar shakes, aluminum siding, or clad board.
