Wat onze klanten zeggen
Ervaringen en inzichten over onze producten
The transparency is really good; you can see right through it.
Reusable material, so there’s no need to throw it away after one season.
The film really keeps the heat in and the drafts out. My windows always had condensation; not anymore. Five minutes to install, and you’re done.
Not only insulation but also UV protection for furniture. It’s great that it’s so durable and doesn’t wear out after just one winter.
This was exactly what I was looking for for my older single-glazed windows. No hassle with tools, just stick it on and you can immediately feel the difference in terms of drafts.
