Metal reflects radiant heat from the sun, minimizing midday heat gain. This allows you to save energy needed for air conditioning during the day. Though the material itself is low in insulation R-value, many systems utilize dead-air space between the metal and roof deck to increase energy efficiency. Some eco-benefits of installing a Canadian metal roofing system
• Reduces attic temperatures by up to 34%
• Integral “dead” airspace blocks heat transfer by conduction
• Lower cooling load can extend air conditioner life
• Integrates with most photovoltaic solar collection systems
• Low weight allows installation over most existing roofs
• Eliminates the need to dispose of old roofing in landfills
• Long-life sustainability
• Low weight roofing can extend a building’s life
• 100% recyclable
• Virtually zero out-gassing
• Fire-resistant
