Easyfix Filmglaze – Thermal Film Insulation
Filmglaze is a simple secondary glazing system that uses special thermal film as an insulator instead of glass or plastic glazing sheet. The film provides a thermal seal by being attached to the window surround by double sided adhesive tape, after which gentle heat is applied to the film to take out wrinkles and provide a smooth tight finish that traps air and insulates the window.
Filmglaze is very affordable, as it does not require the extra cost of glazing sheet, it allows emergency access to the window, and the film itself can be re-used once it has been carefully cut out. It is ideal for student accommodation or rented property and will ordinarily last for a complete winter. If you find that after a while the film begins to sag or wrinkle a little, this is normal and can be addressed by repeating the careful heating of the film with a hairdryer.
It is possible to re-fix handles and other fittings through the film, which is also repairable if punctured, using ordinary clear tape.
Filmglaze is available in 3 pack sizes, Small 1.8m², Medium 4.5m² and Large 9.0m².
Comprehensive fitting instructions and Surface Preparation Wipes along with enough tape to fit each pack are included.
The actual film size is 1.5m wide and 1.2m, 3.0m and 6.0m in length for each of the packs respectively.
- Measure the window area that you wish to fit the Filmglaze over and add a minimum of 20mm to each measurement to work out the size of sheet you need. Then order the kit size that is large enough to cover the new dimensions.
Tools required to fit are a tape measure, hairdryer and a sharp craft knife or pair of scissors.
- Clean and degrease the window frame using Easyfix® Surface Preparation Wipes. Remember to clean the original window at this stage.
- Apply the double-sided tape to the window frame allowing it to overlap at each end, once all four sides are complete trim off the excess tape and press into place firmly. DO NOT REMOVE BACKING YET.
- Completely unfold the glazing film so you are only using a single layer. Then offer the film up to the window and mark or cut the required amount allowing for a little excess that can be trimmed off once fitted.
- Remove the backing paper from the top length of tape and holding the film by the top corners apply the top edge along the tape keeping the film as flat and taut as possible.
- Remove the backing tape from the remaining three sides and holding the bottom corners flat and taut apply these in the same way. If you have large wrinkles the film can be peeled carefully and replaced.
- Once in place press firmly into place on all sides.
- Using the hairdryer on the lowest setting begin heating from the top left corner and work down toward the bottom right. If the film does not appear to be shrinking/tightening move it a little closer, generally between 2-5cm away should work well.
- Apply heat to the whole sheet to tighten the film to a clear and taut finish. Leave for 30 seconds and it should give a tight drum like sound when tapped.
- Finish the fitting by trimming the excess film outside the tape edges.
- Trace around sheet with a pencil on the window frame.
Packing Strips are a self adhesive plastic strip that can be fitted to the frame before the steel strip to raise the glazing sheet off the mounting surface a little further to help sit it proud of any protruding staff beads.
Surface Preparation Wipes can be used to clean and degrease any surfaces before sticking the tapes in place.
Antistatic Spray can be used to diffuse the static charge on the sheet when the film has been removed to help prevent the attraction of dust and particles from the air.
Microfibre cloths can be used to clean the sheets without scratching the glazing panels.
Easyglaze: A self-adhesive base section is fixed around the window and a top section clips into the base to hold a 2mm plastic glazing sheet in place providing cost effective heat and noise insulation.
