Squid keeps a lot of the sun's heat out, so it's an ideal solution on windows that are exposed to strong sunshine, and it can withstand extreme humidity too. It's also breathable, unlike plastic window-covering film, so it's even suitable for HR++(+) glass / high-performance glass. Only the black version (Coal) may not be used on this type of glass.
We think it's important our product is thoroughly tested, so we exposed Squid to strong solar radiation in a laboratory environment. We also tested it up to 99% humidity in this environment. It passed both tests perfectly, and the adhesive strength of the glue wasn't affected at all.
Heat from the sun is blocked twice when you use Squid: firstly because there's no air gap between your sun-resistant material and the glass, and secondly because the fabric reflects some of the sunlight. So you can stay cool inside. Depending on which colour you choose, 25%–36% of the sun's energy is reflected. Tests have shown that it reduces the temperature by at least 3°C.
You can use Squid on roof windows such as Velux skylights, south-facing sliding windows, glass roofs, domes, conservatories, etc. And unlike plastic window-covering film, you can use Squid on HR++(+) glass / high-performance glass, too. Neither the glue nor the fabric suffer any adverse effects from strong UV rays. You can find more information about this in our FAQ section.
