Reduce draughts and retain heat - With a secondary glazing effect
Creates a secondary glazing effect on existing windows and secures in place using the supplied self-adhesive fixing tape. The film can be applied over the inner pane to improve the barrier against cold air.
Reduced draughts make rooms feel warmer and help keep heat inside during colder months, improving comfort without permanent installation.
Custom fit for awkward windows - With cut-to-size film
Can be trimmed to match window dimensions before fixing, allowing adaptation to non-standard or irregular frames. Cutting to size ensures edges align with the frame.
A tailored fit closes gaps more effectively than one-size solutions, making the film practical for older windows and odd shapes.
Reduce condensation and protect timber - Thanks to improved interior sealing
By limiting cold air inflow and retaining warmer indoor air near the glazing, surface condensation is reduced according to user experience. Included fixing tape holds the film to the frame for consistent coverage.
Lower surface moisture reduces the risk of timber rot and paint damage on window frames, helping preserve window condition over the season.
