How does fibreglass roof insulation work. Fiberglass insulation was created in the early 1930s by a scientist at owens corning as an alternative to the highly combustible materials used to insulate homes in those days. Bubble wrap insulation and bubble wrap duct insulation have grown in popularity over the years and more and more people today are using it today for controlling heat and cold in homes and saving on energy costs. It is non conductive. Reflective insulation and fiberglass work differently and one type may be better than the other for specific needs though neither is inherently objectively better for roof insulation.

Persistent roof leaks increase moisture in attics which contaminates fiberglass batt insulation. A good average to work to would be between 70 90 per square metre for a basic fibreglass roof without any additional repairs or upgrading to the roof structure and no insulation. How does loft insulation work. Wet fiberglass insulation has no r value until it dries out unlike foam board or sprayed foam insulation which keeps its insulation properties even when wet.

Bubble wrap insulation works exceedingly well beneath floors walls windows and attics. For a warm deck roof at the other end of the spectrum expect to pay nearly double this at 140 per square metre. The space between the roof and the ceiling is called the loft. Heat insulation in buildings.

How does insulation work to prevent heat loss. Glass fibre or other loft insulation materials are laid across the loft to reduce the rate of heat transfer out of the roof see the picture below. Insulation guide insulation technical articles white papers no comments. Fiberglass is a composite material made of a plastic matrix reinforced by tiny glass fibers.

How does fiberglass insulation work. It is lightweight yet strong and since glass isn t a good conductor of heat it s a very effective insulation material. Fiberglass insulation is not very efficient against moisture.
