Closed Cell Spray Foam

If you're looking for the best insulation available in Peterborough & The Kawartha's, look no further. Just Spray It is your most trusted local insulation contractor to install Closed Cell Spray Foam. Closed cell spray insulation is made of tiny, sealed pockets within a rigid foam. It provides better insulation per inch than any other insulation, and acts as a barrier against air and moisture, making it suitable for use in harsh northern climates, particularly in basement walls, roofs, and exterior walls.

Blow-in Fiberglass

Blown fiberglass insulation in the attic is an effective method for improving your home's thermal performance. This insulation is made from fine glass fibers and is installed by blowing it into the attic space. It creates a thermal barrier that helps regulate indoor temperatures, reducing energy consumption and heating or cooling costs. It is also known for its sound-dampening properties, which can improve the acoustics in your home. Blown fiberglass insulation is non-combustible and resistant to moisture, mold, and pests, making it a durable and safe choice for attic insulation.

DC315 Ignition Barrier

DC315 intumescent paint is a fire-retardant coating used in construction. It expands when exposed to heat to create an insulating barrier that slows down the spread of fire. It is often used on spray foam and other building materials to provide fire protection and help delay the collapse of the structure in case of a fire. Intumescent paint is a popular choice in commercial, industrial, and institutional buildings because it provides fire protection while being a much faster solution compared to other fireproofing methods.

Client Testimonials

How do I know I've been very well served by any contractor? They are attentive; reasonably priced; follow through on their promises and work in a timely way and, most importantly, provide excellent work. Just Spray It has been an excellent experience for my cottage insulation work, restoring my enjoyment received from top-notch service. I will certainly continue to call them in future and suggest them to others with similar needs.

Awesome service from initial inspection (Rob) to completion (Rob, Jay and Mitch). They advised me in advance what was required to prep for a smooth application, showed up as scheduled and competed in great time. Very personable guys who left a clean work site. Anyone who knows what I was dealing with prior to this application is completely shocked at the difference in temperature - my basement is now the same temperature as my main floor. Best decision! Have already referred them to friends, and planning to get a quote for my attic insulation too!

Rob and team have done a great job on time and under estimate. Refreshing to have a good communication and honest service. Site was left clean and tidy with 2x4 faces clean and ready for drywall. Thanks for the service and would highly recommend it.
