Many older houses still feature single pane windows that are not up to modern insulation standards. Especially during winter time, such windows feel cold and considerably lower the room temperature. This requires extra heating and drives up your energy bill.The tesamoll® Thermo Cover is a transparent insulation film especially designed for single pane windows. It forms an insulating cushion of air which offers an insulation effect similar to that of an additional pane of glass. Since this prevents any direct contact of the window's glass with the warm inside air, it also effectively reduces the condensation effect typical of single pane windows.Thanks to the double-sided mounting tape included in the package, attaching the tesamoll® Thermo Cover is a simple affair requiring only a few minutes. To smooth it out, warm up the air cushion film with a hair dryer and stretch it taut. It is really a small effort to enjoy a totally new level of comfort. * Designed for single pane windows * Reduces condensation effectively * Forms a cushion for added insulation * Easy mounting with double-sided tape
