Attics and cathedral ceilings
Attic and cathedral ceiling insulation.
Warm air rises. If it finds a way into the attic, your heating escapes through the top. Spray foam seals those leaks and insulates cathedral ceilings and the underside of the roof deck, where it truly makes a difference.
The problem
Heat escapes through the top.
Warm air escapes from the house into the attic through openings in the ceiling: the access hatch, recessed lights, ducts and wire passages.
In a cathedral ceiling, the space between the rafters is shallow and leaves little room for insulation. The rooms under the roof become hard to heat.
What spray foam changes
Spray foam where it is truly superior.
Spray foam seals air leaks between the house and the attic. In a cathedral ceiling or under the roof deck, it insulates and seals in a single application, even in a shallow space.
At equal thickness, it insulates almost twice as well as traditional batt insulation (about R-6 per inch). To insulate the floor of a large ventilated attic, another insulation may be a better fit: we tell you honestly in the quote.
Roof ventilation and Building Code requirements are assessed before the quote. Thermik tells you what is required for your project.

Frequently asked questions
Your questions about this project.
Spray foam or cellulose for my attic?
It depends on your attic. Spray foam is superior for sealing air leaks, insulating a cathedral ceiling or insulating under the roof deck. For a large ventilated attic that is easy to access, cellulose may be a better choice. After seeing your photos, we tell you honestly which option fits your situation.
Can you insulate a cathedral ceiling?
Yes. Spray foam is well suited to cathedral ceilings, where the space between the rafters is limited. The thickness applied is specified in your written quote.
Do you need to visit to give me a price?
Not always. Photos of the attic access, the inside and the roof help us prepare the quote. If a visit is needed, we will tell you.
