If you're stuck with draughty single-glazed windows and can't replace them, tesamoll film creates a cheap secondary glazing effect — stick it on in autumn, hairdryer it tight, take it off in spring, and cut heat loss for under a tenner per window.
Problem it solves
Reduces heat loss through single-glazed or poorly insulated windows by creating an insulating air gap between the film and the glass, cutting heating costs and reducing condensation.
Who it's for
Renters or homeowners with draughty or single-glazed windows who want a temporary, low-cost insulation upgrade without replacing the windows.
Why we recommend
Will reduce heat loss and condensation if installed right - fast payback.
Savings
- Typical annual saving
- £15–£40/year per window depending on window size, heating type, and energy costs (manufacturer claims up to 8% energy saving)
