Heat Protection Film for Windows

Heat protection film and solar film describe the same product. Both terms refer to a window film that reflects or absorbs solar radiation to lower room temperature. The term heat protection film emphasises the thermal effect, while solar film emphasises protection from sun exposure.

Depending on the film type and tint level, heat protection film reduces solar energy by up to 90%. Exterior films are more effective than interior films as they reflect radiation before it reaches the glass. Interior films achieve up to 80% reduction.

On insulated glass, thermal glass and double glazing, only exterior film should be used. Interior films on these glass types can cause thermal glass breakage as the space between panes heats up excessively.

Yes, heat protection film reduces light transmission. The stronger the heat protection, the darker the film. Dark films allow approximately 16-20% light through, medium tints around 30%. For rooms that need to stay bright, a lighter variant with less heat protection is recommended.

In winter, the film also reduces solar heat gain through windows. In rooms with strong sun exposure (conservatories, south-facing windows), this may be desirable even in winter. For purely seasonal use, the static adhesive-free variant is ideal.

The film is applied to the clean glass surface using water and a little washing-up liquid. Interior films can be installed yourself; for exterior films on upper floors, we recommend a professional installer. The installation kit with squeegee and cutter is available in our shop.

Self-adhesive films can usually be removed without residue by heating with a hairdryer and peeling off slowly. The static variant adheres without glue and can be removed and reapplied at any time.
