Idaho's winters demand real insulation. If your home feels drafty, your energy bills keep climbing, or your attic has old, compressed insulation, HardKnock Exteriors delivers professional spray foam and blown-in insulation treatments that seal your home envelope and slash your heating and cooling costs.
The Department of Energy estimates that 25–30% of your home's heating and cooling energy is lost through inadequate attic insulation. In Idaho's climate, that translates to hundreds of dollars wasted every year.
Closed-cell spray foam provides the highest R-value per inch of any insulation material available. It also acts as a vapor barrier and structural reinforcement, making it ideal for Idaho's freeze-thaw climate. Applied directly to roof decking or attic surfaces, it creates a seamless air-tight seal that eliminates drafts and prevents moisture intrusion.
Open-cell foam is lighter, more affordable, and provides excellent sound dampening in addition to thermal insulation. It expands to fill irregular spaces and is ideal for interior walls, attic floors, and areas where moisture vapor permeability is preferred. A great choice for homeowners looking for meaningful improvement at a lower cost.
Made from recycled paper products and treated with fire retardant, blown-in cellulose is an environmentally responsible insulation option. It fills gaps and settles into irregular attic spaces, creating a thick thermal blanket over your ceiling. It is one of the fastest and most affordable ways to improve attic insulation levels.
Radiant barrier insulation is installed in the attic to reflect radiant heat away from your living space. In Idaho's summer months, this can reduce attic temperatures by 20–30 degrees, taking significant load off your air conditioning system and extending the life of your roofing materials.
If your roof is being replaced, it is the perfect opportunity to upgrade your insulation. With the roof open, our crew can apply spray foam directly to the decking, creating the most effective thermal envelope possible. Bundling saves you labor costs and ensures a seamless integration between your roofing and insulation systems.
Ice dams form when heat escaping through your roof melts snow on the upper sections, which then refreezes at the eaves. This can cause serious water damage. Proper attic insulation combined with adequate ventilation is the permanent solution. HardKnock addresses both the insulation and the ventilation to eliminate ice dams for good.
