Robust Insulation for your beautiful home
Many unfinished attics can benefit from blown-in insulation as long as it is not moist or compacted. Unfortunately, some homes, particularly older homes, have insufficient insulation, wet or damaged insulation, or insulation contaminated by rats and their droppings. Closed cell foam insulation has a high thermal resistance, making it a good option for places where a high R-value is desired. It is not a do-it-yourself project to install closed cell foam that is sprayed on.
Prepping the Attic
Proper attic ventilation should be a priority for homeowners. Although it varies, an unfinished attic often has fresh air intake vents in the soffits and one or more exhaust vents towards the peak, either in gables or on the roof. Because closed cell foam will enclose the attic, you’ll need to find another way to ventilate it. Rafter baffles are often installed in every rafter spacing to provide fresh airflow from the soffits to a ridge vent at the roof’s peak.
The Insulation Process
Carefully select a foam-insulation contractor. Closed cell foam application necessitates precise chemical mixing and spraying at the proper temperature. The closed cell foam, which begins as a liquid and quickly grows between the rafters, is directed by the contractor. Due to the dense nature of closed cell foam, it may not completely fill the rafter area, but it should be of uniform thickness. For example, if you want R-30 insulation and your roof has a two-by-twelve rafter framework, the contractor will spray the foam 5 inches thick, leaving more than half of the space vacant. You can hang drywall the same day because the foam swells and hardens practically instantly.
The best way to get all these done would be by contacting Attic Insulation who is considered to be one of the blown insulation contractors plano.
