Doors & Windows
Around 15% of your homes heat is lost through your doors. Choosing and correctly fitting doors with good U-values will pay for themselves over time.
In turn, around 10% of your homes heat is lost through your windows, the majority through the glass. The U-values of windows and their energy rating should be considered in addition to their quality and security.
Heat loss also occurs around windows and doors, accurate measurements for well fitted windows and simple draught proofing with caulking sealant can greatly reduce overall heat loss.
