    Brilliant communications, both telephone and online. Ordering our secondary glazing was so easy. Printed and online measuring instructions were simple to follow. Everything arrived well packaged and cut and assembled to perfect size.
    Installation was quick and simple. Looks a treat.

    Delivery was as stated, and a phone call the day before to confirm it. Product well packaged. My only criticism would be that installation instructions were not included, although the website indicated that they would be. I had installed them before, but several years ago, and a reminder...
    Please accept our apologies for the omission. It is standard to make sure you receive these via our email at the time of dispatch. They are also available to view when you sign in to our web site: they are found under "My Extraglaze".

Colour-matched (laminated)



Please order by the metre (always sold as a pair*). Note: this is offered here as a "spare part" because it is already included with every panel you purchase.


Self adhesive magnetic tape. An incredibly strong, white adhesive on the back. Overall thickness approx. 2.5mm.


Use this on the window frame. Please select the best colour match (an effective camouflage) or this will be visible as a thick line around the window frame unless Extraglaze panels are installed over it.


The pink you see in the picture is the disposable release film, which protects the adhesive until you fix it.


This can also be stuck to acrylic sheet: when looking through the plastic, you will see the colour of the adhesive foam i.e. white.


*Sold as a pair

You will always receive a matching pair, one magnet to be stuck to the panel, one magnet to be stuck to the window frame. When you order a colour-matched length then the magnet intended for the window frame will be laminated in your choice of colour, however the magnet intended for the panel will be natural (never laminated).
