Polyurethane insulation is great for climate control and it makes steel garage doors more durable and energy efficient. This insulation serves a wide range of purposes for both residential and commercial applications.
Polystyrene insulation is thicker and of higher quality than polyurethane. Polystyrene is more energy efficient and durable in harsh environments such as warehouses and loading docks.
Steel economy doors come in premium-duty 20 gauge steel up through heavy-duty 24 gauge steel and require no extra insulation. These doors are well suited for a variety of commercial and industrial uses.
