Ceiling Insulation Energy Savings
How Roof Insulation Reduces Electricity Costs
A large portion of heat entering or leaving a home occurs through the roof. Without proper insulation, homes can become extremely hot in summer and lose heat rapidly during winter.
Roof insulation helps reduce heat transfer by creating a thermal barrier between the roof and the living space.
Benefits of installing ceiling insulation include:
Reduced electricity consumption
Lower air-conditioning usage
Improved indoor comfort
Lower heating costs during winter
Ceiling insulation is one of the most cost-effective energy improvements that can be made to a home.
