Easyfix Magnetglaze Pro Extreme – large window insulation

Magnetglaze Pro Extreme is a rigid capping with strong 25.4mm wide magnetic tape applied, which pushes onto the edges of 4-6mm glazing sheet to provide a smart finish that can be mitred in the corners for a framed effect. The capping is available in white or brown, and the assembly comes with the adhesive steel tape for attaching to the window surround. Each pack includes a special Mitre Bead, that pushes into the capping jaws to hold it constant for better looking cuts and joints. MG Pro Extreme is a larger and more powerful version of the popular Magnetglaze Pro, that uses 12.7mm wide magnets, making it suitable for small to medium sized windows.

PDF The PDF instruction sheet on this page contains a full step-by-step guide to measuring and installing your capping strips using simple household tools. When fitting, make sure to clean and degrease your window surround using our Surface Preparation wipes before sticking the steel tape into position. Additional accessories include the large Mitre Block, for neat 45 degree corners (note that Magnetglaze Pro Extreme is too large for our standard Mitre Block) and you can remove static when peeling off the plastic sheet protective film using our Anti Static Spray.

Glass should never be used with Magnetglaze Pro Extreme, and completed panels are not suitable for an opening door or window frame, or for use outdoors.

If your window is so large as to make a single sheet unfeasible, or you want a part-removable pane for easy ventilation purposes, you can use Magnetglaze Sash Heavy Duty. This add-on system uses a rigid joint with additional seals, so that removal and replacement of the pane is instant, with insulation fully restored. Note that MG Sash Heavy Duty is for 4mm thick sheet only.

magnetglaze pro secondary glazing dimensionsThe 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.

Please note that as Magnetglaze Pro Extreme purchases already include the magnetic and steel tape they use, you do not need to order Magnetglaze Extreme packs for use with them, although you need to specify and order the Pro Extreme packs/lengths of course!

magnetglaze conversion anglesIf there is not enough space on the surfaces of your window surround to fit Magnetglaze Pro Extreme, Window Conversion Angles can be attached on the insides of the frames to give a suitably wide surface. These are strong Angles with a 25mm face, 3mm thick, in white or brown to complement the kits. More information is in the PDF alongside, with product details on the right hand side of this page
