Providing heat can often be as much a concern as cooling a glazed structure. While heating systems are one means, another option is simply retaining and making maximum use of the heat is already present.
WSD can equip your glazed structure with heat retention curtains. While they can provide a measure of shading, heat retention curtains are constructed of materials that trap warm air and reflect radiant heat back into your space. They are installed internally and are also often installed horizontally, at eave height, to focus heat where it’s most needed.
