When used as a patio roof, the homeowner will recognize the benefits immediately. Snap-N-Lock insulated roofs can save as much as 50% over conventional construction without sacrificing durability, strength, or beauty. The continuous insulation provided by the panels, in the hot summer months, keeps the heat outside where it belongs. You stay cool and comfortable. In the winter, heat generated within the home is contained, helping you stay warm. Since the panels are insulated, condensation problems are eliminated.
