Window insulation kit designed to cut draughts and retain heat through winter. BKSAI Window Insulation Film Kit creates a clear, reusable barrier for older or rented windows while letting daylight through. Is a non-permanent glazing solution the right choice for your home?
⚡ At a Glance
- • Thermal Performance: 20% more heat retention by forming a sealed air gap with a thickened 0.15mm transparent EVA layer
- • Best for: Bedrooms, living rooms, kitchens and hotel rooms where draught reduction and reduced condensation are priorities
- • Not ideal for: Situations that require heat-shrink installations or a permanently fixed glazing solution
A 0.15mm thickened transparent EVA film creates a sealed air gap to reduce heat loss. Strong cold-resistant hook and loop mounting keeps the film removable, reusable and virtually invisible on the window.
Warmer Rooms and Less Draught – thanks to thickened 0.15mm EVA film
The film is thickened from 0.02mm to 0.15mm, increasing toughness and creating a sealed air gap that mimics an extra pane of glazing. That trapped layer of air reduces conductive heat loss through the window.
Rooms retain more warmth and feel less draughty, reducing reliance on heating and lowering the chance of cold spots. Condensation on the inside face is also minimised except under very high humidity.
Reusable, Cold-Resistant Mounting – with strong hook & loop tape
A supplied hook and loop tape uses strong adhesive formulated to remain secure in cold conditions and allows the film to be removed and refitted. The mounting avoids one-time adhesives and permits easy seasonal removal.
Quick removal for cleaning or ventilation saves money versus single-use films, and the reusable mount makes the kit suitable for rented properties and short-term measures.
Clear View and Low Condensation – with crystal-clear insulation film
Transparent EVA film hangs like an additional pane of glass and transmits light without noticeably altering the view. The thicker insulation layer reduces moisture build-up on internal glass under normal humidity levels.
Natural light passes through and outside sightlines remain intact while internal panes stay drier, helping to protect frames and window fittings over time.

❓ Frequently Asked Questions
Q: How much insulation improvement can I expect?
A: Manufacturer information states around 20% more heat retention by creating a sealed air gap between the film and window pane. Actual results will vary with window type and room conditions.
Q: Can the film be removed and reused?
A: Yes, the film uses a strong, cold-resistant hook and loop tape that is removable and reusable for cleaning or seasonal use.
Q: Will the film affect light levels or the view?
A: No. The insulating film is described as crystal clear and virtually invisible, so it lets light through without noticeably impairing the outside view.
🏆 Our Verdict
Best suited for homeowners and renters with draughty or single-glazed windows seeking a non-permanent insulation fix. A thicker 0.15mm transparent EVA layer combined with cold-resistant hook and loop mounting delivers glazing-like insulation while remaining removable and clear. Long-term value comes from seasonal reuse and reduced condensation, with potential energy savings over repeated winters.
