Why is insulating a pitched roof important?

Did you know up to 25% of a home’s heat escapes through an uninsulated roof? That’s a lot of wasted energy – and money. Insulating your pitched roof is one of the most effective ways to maintain a comfortable temperature in your home, keeping it cool in summer and warm in winter.

Pitched roofs are a popular choice for both homes and commercial buildings, but without proper insulation, energy costs can skyrocket. By insulating your roof, you’ll enjoy:

Significant cost savings: Reduce energy bills by preventing heat loss through the roof. After all, heat rises -don’t let it escape!
Improved temperature control: Get a handle on extreme temperatures with insulation of pitched roofs all-year round with better heat retention.
Lower carbon emissions: Less energy lost, less heating meters cranked up, less environmental impact you’ll have.
Less dampness: Insulation helps prevent moisture build-up, protecting your home from damp and mould.

Warm vs. cold roof

When insulating a pitched roof, you’ll need to choose between a warm roof and a cold roof. Each method offers distinct benefits depending on your needs and building type.

Warm roof:

In a warm roof setup, insulation is installed above and between the rafters, keeping them warm. This approach traps heat effectively, ensuring that rooms stay cosy and comfortable, especially in colder regions. It’s ideal for new builds and when reroofing existing structures because it offers superior thermal performance and maximizes energy efficiency.

Cold roof:

With a cold roof, insulation is placed between and below the rafters, leaving the rafters themselves cold. This method is generally less expensive and takes advantage of the space available in the loft. It’s perfect for keeping the loft area cool while maintaining comfort in the main living spaces.

At Belgrade, we offer top-quality products and expert advice, ensuring you get the best insulation for your roof – every time. Consider your specific needs and consult with our experts to make the best decision for your property.

Frequently asked questions

How to insulate a pitched roof from the inside?

To insulate a pitched roof from the inside, start by preparing the space: ensure it’s clean and check for any signs of damage, as well as measuring all the gaps between the rafters. Then, cut your insulation to the right size and push it into the space. Finally, cover everything with plasterboard or another finish, making sure the joints are well-sealed.
