If you are planning to renovate your roof, you should definitely consider insulation because it protects your home in many ways. But what type of insulation? What are the questions to ask yourself? Cedral gladly helps you decide which options are the most suitable for you.
With roof insulation, we refer to adding insulation on your roof slope, above and below the rafters. Insulation materials typically have low thermal conductivity, so they reduce the overall heat transfer coefficient of your roof. Without insulation, a considerable part of your heating disappears through the roof, but with insulation, your roof lets less heat escape from your home.
The advantages are clear. With insulation you can more easily regulate the temperature in your home. As you lose less heat, this will have a positive effect on your energy bill, saving on heating expenses. But this is not only good for your wallet, less energy use is also good for the planet. And last but not least, it contributes to long-term weather prevention.
There are two types of roof insulation: hot versus cold.
The most commonly used insulation materials are rigid foam insulation boards, radiant barriers and spray foam. They are all compatible with Cedral slate roofs.
Do you want to cut your energy bill? Insulation will let less heat (or cold in summer) escape. This way you need to heat or cool less. This will lead to considerable cost savings. You will recover your investment in a few years thanks to your reduced heating or aircon bill.
Do you have ventilation ducts on your attic? It can get very hot under your roof. If your HVAC ducts pass through your attic, they will also require insulation against heat. With hot roof insulation, your ducts can remain cooler as your attic has a more conditioned stable temperature.
Are you living in a cold climate? Cold outside temperatures often lead to condensation on the inside of your roof if not insulated well. Ice dam formation on your roof might also lead to water infiltration between your slates. Proper insulation prevents moisture damage to your roof structure.
Do you care about sustainability? We hope so, because we do. With insulation, you can considerably reduce your energy consumption. And the greenest energy, is the energy that didn’t need to be generated. So, insulation makes your home more energy-efficient, which is beneficial for the climate.
