Magnetglaze Extreme is a new product introduced specifically for large panes and very draughty windows, where the extra grip provided by 25.4mm magnets and steel combats the heavier plastic glazing sheet and the effect of high winds on leaky outer panes. The system is effective for both heat and noise insulation, the finished panes being easy to take off and put back. Magnetglaze Extreme is the stronger version of our popular Magnetglaze system, which remains very suitable and cost effective for small to medium panes where howling draughts are not an issue. For both systems, steel tape is stuck to the window surround, magnetic tape to the back of the glazing panel, allowing it to clip neatly into place. Cosmetically, they are both unobtrusive, showing the white adhesive tape on the back of the magnets, but the appearance can be rendered smarter with our Finishing Trim add-on.
For practical and safety reasons, we recommed that you never use magnetic glazing with glass, on doors, roof lights or the opening part of a window, or externally.
Using Magnetglaze Extreme is simple, with full step-by-step instructions for measuring up and installing in the PDF on this page. The innovative 10m dispenser pack, with adhesive steel and magnetic coils that can be drawn out and cut without difficulty, makes the whole job simpler. Just clean down the surface on which the steel will be stuck, using our Surface Preparation Wipes, then cut and apply the strips as required.
Although the appearance of Magnetglaze Extreme is reasonable, many customers choose to use our Finishing Trim, which at 32mm wide can be used to mask both the tape and the cut edge of the sheet if needed. For illustrative pictures, see at the bottom of this page. The Trim comes in either White or Brown, can be neatly cut and mitred using strong scissors and gives the finished job that professional edge. Packs comprise 2 x self adhesive 5m coils plus 2 Surface Preparation Wipes. Alternatively, you can use Magnetglaze Pro Extreme, where the magnets are attached to a smart plastic capping, again in White or Brown. Should you want to joint the pane, in order to make several more manageable pieces or easier ventilation, you can use Magnetglaze Sash Heavy Duty, that provides a rigid horizontal joint but maintains full insulation. This add-on system is suitable only with 4mm sheet.
The products on this page can use glazing sheet of up to 6mm thick, which we are unable to provide. The One Stop Plastic Shop do offer this - they are an independent company with whom we have traded for many years. Click through for 6mm cut to size Polycarbonate or 6mm cut to size Acrylic if you want to buy direct from them. Otherwise, 4mm sheet tends to provide a good balance between cost, weight and rigidity, and is the most popular choice of our many customers for the Magnetglaze Extreme system.
If there is insufficient space on all sides of your window surround to fit Magnetglaze Extreme, Window Conversion Angles can be fixed to the insides of the frames giving a clean wide surface. They are heavy duty Angles with a 25mm face and 3mm thickness, in white or brown to match the kits. More information is in the PDF below, with product details on the right side of this page.
