Secondary Glazing is the cheapest most efficient way to reduce your energy bills and heat loss. We have many options for you with this. The most common is the magnetic system which is self adhesive and easiest to remove and replace. We also have flexible edging and turn buttons, this is the option for shaped windows. Superglaze is a more permanent method as perspex sits in a channel and is then screwed on to the window frame and has a cover strip that clips over the screws. Our last two options are Trackglaze with draught excluders or 4mm twin tracks in Black or white.
