INSTALL WINDOW FILM | TOOLS & ACCESSORIES

✅ Before Installation – Preparations

When applying window film to glass panes in houses or flats, there are several important things to consider to achieve a long-lasting, neat, and effective result. Here’s an overview divided into before, during, and after installation:

1. The right type of film for the right glass

   • Select film based on purpose: solar protection, privacy, safety, energy efficiency, or decoration.

   • Check the glass type – tempered, laminated or standard float glass. Some films can cause thermal cracking if combined incorrectly, e.g., with insulated glass.

2. Cleaning the glass surface

   • The glass must be completely free of dust, grease, and cleaning residues.

   • Use, for example, isopropyl alcohol and a scraper/squeegee to achieve a spotless surface – including edges and corners.

3. Temperature and environment

   • Ideal temperature: 10–25 °C (neither too cold nor too warm).

   • Avoid direct sunlight on the glass during application – it dries the solution too quickly.

   • No wind or dust in the air (for outdoor film).

🔧 During Installation – Step by Step 

NOTE! General description, please see our  Installation Guide for detailed instructions. 

1. Use plenty of application solution

   • Apply a mixture of water and a few drops of washing-up liquid (or use a specialised solution).

   • Spray both the glass surface and the adhesive side of the film – this allows room to adjust the position.

2. Attach the film from the top

   • Start from the top and work downwards, ideally with a helper if the film is large.

   • Use a plastic or rubber squeegee to press out liquid and air bubbles, from the centre outwards.

3. Trim the edges precisely

   • Use a sharp knife or scalpel and a metal ruler for accurate edges.

   • Leave a small gap (~2 mm) between the film and the window frame to prevent peeling.

🧽 After Installation – Curing and Maintenance

1. Let the film cure

   • The film can take up to 30 days (depending on weather and film type) to fully dry.

   • During this time, small bubbles or “haze” may appear – this is normal.

2. Avoid touching the film

   • Do not clean or rub the film during the first month.

   • After that, clean with a soft cloth and mild soapy solution (no ammonia or abrasives).

⚠️ Common Mistakes to Avoid

• Not cleaning thoroughly – small dirt particles become bubbles under the film.

• Cutting into the frame – this can damage seals or leave unsightly marks.

• Applying in direct sunlight or on too cold surfaces – the film won’t adhere properly.
