A DIY secondary glazing kit including a 1.6 x 10m shrink film roll and 42m of extra-wide clean-removal tape. The 23-micron tear-resistant film and wide adhesive aim to cut draughts and lower condensation.
Warmer rooms with reduced draughts – thanks to 23-micron shrink film
The tear-resistant 23-micron film forms a clear secondary layer over the original pane, creating a thermal barrier that limits heat transfer. Shrinking the film around the frame produces a tight seal that reduces air movement at the window edge.
Noticeably less cold from single-glazed windows and reduced heat loss across winter, helping rooms feel more comfortable without structural changes.
Simple installation for DIYers – with extra-wide clean-removal tape
A 42-metre roll of 2cm wide adhesive provides a stronger grip and easier handling than narrow tapes, while the tape is designed to peel away cleanly. The kit includes clear instructions so the tape and film can be applied by hand.
Faster, less fiddly fitting across multiple windows and a straightforward spring removal that avoids sticky residue on frames.
Large coverage and durable finish – with a 1.6 x 10m roll
The generous film roll size suits a variety of window shapes and sizes, from small panes to larger picture windows, while the thicker material resists tearing. Crystal-clear film preserves daylight and external visibility.
Cover several windows from one kit and expect a durable, clear insulating layer that lasts through the colder months.
