OUR SELF-ADHESIVE HEAT PROTECTION FILMS

Modernize windows instead of replacing them – for perfect heat protection and optimal indoor climate

When thinking about renovation, most people quickly consider major measures: photovoltaics, new heating systems, insulation – or replacing windows.

But what many don’t know: there’s a much simpler, more economical, and more sustainable solution for modernizing existing windows.

Heat protection films.

And this is exactly where Pat & Patachon comes in. You know when it’s Pat & Patachon.

Efficient Protection with Heat Protection Films for Windows

No more excessively heated offices. Look forward to pleasantly tempered rooms in summer – without constant air conditioning.

Our heat protection films reflect a large portion of solar radiation before it enters the building. This noticeably reduces indoor temperature and sustainably improves the indoor climate. At the same time, glare reduction is optimized.

Working at a screen? Much more relaxed.

Relaxing in the living room? Much more pleasant.

Those planning to renovate previously considered these measures! Why Replace Windows When Application Is Enough?

The numbers speak for themselves: only 16.8% of those planning renovations intend to replace their windows. No wonder – replacement is expensive, complex, and involves structural interventions.

Our self-adhesive window films offer a smart alternative. Through professional installation and precise application, existing glass surfaces are upgraded energetically – without construction, without noise, and without long downtimes. The films are applied directly to the existing window glass. Fast. Clean. Efficient.

Install photovoltaics 45.9%
Install solar thermal 31.7%
Replace heating system 25.6%
Replace windows 16.8%
Building insulation 15.1%
Install automated ventilation 5.1%

Double Benefits: Heat Out, Energy In

Modern window films can do more than just sun protection.

They help create the perfect indoor climate, as they:

  • reduce summer heat

  • minimize heat loss in winter

  • improve the energy efficiency of buildings

  • protect furniture and textiles from UV-induced fading

This means: lower energy consumption, reduced CO₂ emissions, and lower operating costs in the long term.

Sustainable Renovation – Without Window Replacement

Those planning to renovate previously considered classic measures such as:

  • Install photovoltaics

  • Install solar thermal

  • Replace heating system

  • Improve building insulation

Window replacement was rather mid-range. With heat protection films, a new, intelligent renovation option emerges: modernization through enhancement rather than demolition.


Our solutions are environmentally friendly, resource-efficient, and economically sensible. A true win-win situation for budget and environment.

Measurable Benefits: Energy Savings Made Easy

Modernizing windows with high-quality heat protection films can achieve impressive results:
