Easyfix Magnetglaze Sash Heavy Duty – 4mm Panel Insulation

Magnetglaze Sash Heavy Duty provides insulation and access for large or draughty sash windows, or any other windows where jointed panels are required. It is an add-on to Magnetglaze & Magnetglaze Extreme, with or without Finishing Trim, as well as both Magnetglaze Pro and Magnetglaze Pro Extreme systems, all of which need to be purchased along with the Sash Kit. These heavy duty kits use a specially designed rigid jointing strip which maintains the thermal seal for 4mm panels, allowing them to be easily removed and replaced at will for instant ventilation or insulation. The joints, being rigid, are resilient against the kind of draughts that can occur in older sash windows.
The Heavy Duty bulk kits contain enough components to joint 4 windows of up to 1500mm wide. The half kits comprise components for 2 windows, also up to 1500mm wide.

magnetglaze sash installation pdf Installation of the kit requires no special tools and is straightforward. Once the Magnetglaze, MG Extreme, MG Pro or MG Pro Extreme edgings have been attached to both window surround and glazing panels, simply apply Bristle Seal to the open edges of the panels where they will join in the middle of the window, then cut and fit the H Section. Turnbutton clips can be applied to the window to anchor the non-moving pane and to reinforce the magnets against the natural movement of the panes caused by window draughts. See the PDF instructions and video for more details.
