Tubeway (Sales) Ltd are manufacturers, stockists and distributors of Magnetglaze and Magnetglaze Extreme, which are cost effective detachable Magnetic Glazing systems that can be easily installed with a few simple tools. This product is quite simple: adhesive steel tape is stuck to the window surround; magnetic tape sticks to the rear of the plastic glazing sheet, and the two clip together and remove instantly and easily time after time. Tubeway offer a number of specifically designed cosmetic and practical add-ons to both versions of this system, all of which are described below.

We only recommend using plastic sheet (Polycarbonate or Acrylic) with Magnetglaze and the Extreme systems (do NOT use glass). 2mm thick plastic glazing sheet is often suitable for small windows, but 3mm or 4mm can be used for medium and larger windows if required, particularly to add rigidity. As a failsafe, to remove any question of slippage of the magnets on the steel tape, you can place a couple of pins immediately below the bottom steel strip where they will not be seen. However, where the window is particularly large, heavy or draughty, the significant extra grip of MG Extreme will address any issues about magnetic grip, and allow thicker sheet to be used if desired. Contact our Sales team if you want to discuss which width of Magnetglaze might be best for your windows. Always fit magnetic panels to the internal window frame and never to an opening window light.

Like all of our Easyfix Secondary Glazing systems, Magnetglaze and MG Extreme can cut fuel costs by reducing heat loss and eliminating draughts, as well as insulating against noise. Click through for details of all the DIY Glazing systems we offer.

Finishing Trim

Although the appearance of Magnetglaze is quite unobtrusive, it is possible to smarten it and hide any slight defects on the cut edge of the glazing sheet, by adding Magnetglaze Finishing Trim. This 20mm or 32mm wide self-adhesive brown or white flat strip has rounded edges and can easily be mitred for excellent cosmetic results, as shown in the photographs to the right. The 20mm size is designed for standard Magnetglaze, whilst the 32mm Trim can be used to cover the Magnetglaze Extreme strips - both sizes are self adhesive and can be purchased in 5m coils. They are easy to mitre neatly to 45 degrees as they are thin enough to be cut with a strong pair of scissors.

Magnetglaze Pro and MG Pro Extreme

As an alternative to the Finishing Trim, Tubeway also offer Magnetglaze Pro and MG Pro Extreme, which uses the same magnets and steel, but the magnetic strip is already attached to rigid PVC capping, enabling framing of the glazing sheet after cutting 45 degree corners mitres using the special Mitre Bead provided.

Magnetglaze Sash Heavy Duty

Sometimes it is convenient to be able to divide a tall magnetic pane into two parts, using a horizontal joint. Because it is most commonly applied to sash windows, the add on Sash kits can be used for this exact purpose. The Magnetglaze Sash Heavy Duty kit is designed for 4mm sheet, used as an add-on with either Magnetglaze or Magnetglaze Extreme systems. It uses a rigid bar to divide the secondary pane, making it more suitable for large and draughty windows. Details of both Magnetglaze Sash add-on Kits are here.

The standard Magnetglaze is available in window-sized 5m kits, which contain both steel and magnetic strip, with surface preparation wipes for degreasing the window surround before use. The 30m bulk packs come in cardboard dispensers, enabling the exact amount needed to be pulled out, marked and cut by one person, and preventing the need to handle a full coil during use. Apart from the obvious cost savings of the bulk pack, the dispensers make it a very popular product. Don't forget to order Finishing Trim if required for that extra smart appearance.

Magnetglaze Extreme, at 25mm wide, is supplied only in 10m cardboard dispensers, again, for ease of use during installation. To smarten the appearance of the finished secondary panes, Magnetglaze Finishing Trim 32mm version can be used, which can also cover the cut edge of the glazing sheet if needed.

If your window surround has insufficient space to install Magnetglaze Extreme, you can fix Window Conversion Angles to the insides of the frames to give a clean wide surface on all sides. These Angles are heavy duty with a 25mm face, in white or brown. More information is in the PDF alongside, with pack details in the table below.
