Frost or condensation on the inner face of window framing indicates that the frames of the window are acting as a cold bridge from the outside to inside, making the internal frames cold. If you are experiencing this on your own metal framed windows it is essential that you replace them to gain the thermal efficiency required to modern homes.

Thermal Bridging, or cold bridging, can happen in different areas of a construction if the materials used and connections between elements are not properly designed or thought out. When it comes to windows and doors thermal bridging occurs when non-thermally broken frames are used. This means the same frame material on the outside of the building is continuous through the thickness of the frame to the inside. As metal is a good conductor of heat the frame material on the outside of the building will be continuous through the frame to the inside causing a cold internal frame.

The only way to stop cold bridging through older frames is to replace them with modern alternatives.

All aluminium frames from Hedgehog Windows are manufactured with modern thermal break technology, stopping any thermal bridging from the outside to the inside of your replacement windows and improving thermal performance
