Systems are designed to give the customer ultimate protection by locking out the elements. Lower energy costs are possible because a properly insulated building system can produce very high thermal efficiencies. Proper design of the heating/cooling equipment along with a good insulation system can provide lower monthly energy costs over the life of the building. Economical maintenance is also important. Quality siliconized polyester or fluropolymer paint coatings resist cracking, peeling and fading. These coatings are backed by manufacturers’ warranties of twenty years and beyond.
