HOW DOES ASTRO-FOIL WORK TO KEEP BUILDINGS WARM IN WINTER AND COOL IN SUMMER?
ASTRO-FOIL that is in the walls and ceiling of your building is like aluminum foil when wrapped around a baked potato–in the winter it holds the heat in because of the foil’s low emittance. In the summer, ASTRO-FOIL ‘s aluminum surfaces reflect the heat before it can enter, keeping the inside cool and comfortable. The trapped air in the bubbles between the foil layers provides a barrier against conductive heat flow, and because ASTRO-FOIL is solid, it is a convection and moisture barrier, providing additional thermal benefits.
