Insulation

Insulation reduces heat loss through surfaces like the walls, floor, roof, and glazing. Like all energy efficient structures, SunCatchers are well insulated and designed to trap and store heat for as long as possible. The SunCatcher roof and walls are well insulated with waterproof insulating material. Batt insulation which absorbs moisture and loses it insulating properties should NOT be used. We suggest using polystyrene insulation (blue board).  Using triple polycarbonate glazing with an R-value of 2.5 for south-facing glazing reduces heat loss through the glazing on cold days and nights. A reflective insulation “blanket” may be used to cover the glazing at night to further reduce the SunCatcher’s heat loss.
