Welcome to our blog page! Here you will find tips, insights and everything InvisiTherm®

InvisiTherm™ bespoke magnetic secondary glazing is naturally often thought of a winter home improvement, after all, one of the biggest benefits of InvisiTherm™ is its exceptional heat retention benefits. But did you know that it also makes sense to have secondary glazing installed in the summer? Let’s take a look at four scorching reasons to have secondary glazing installed in the summer, to stay cooler and more comfortable any time of the year.

Completely eliminates UV rays

Single glazing and double glazing that dates from before 2003 admits a large amount of ultraviolent rays. These rays can damage furnishings, artworks and documentation by causing fading, but can also cause sunburn and aging damage to the skin. Glaze & Save’s InvisiTherm™ has an ultraviolet filter which blocks over 99.9% of the sun’s harmful rays, eradicating fading, and minimizing exposure to the potentially harmful effects of the sun. This is great for those of us who have light sensitive furniture of artefacts (such as in stately homes), but is also great for preserving the life of your soft furnishings, artworks, curtains or wallpaper: in fact, anything that may ordinarily become faded by the sun.

Reduce the heat of the sun

InvisiTherm™ is known for its exceptional heat retention properties, but did you know that it could also keep you cooler in the summer? InvisiTherm™ reflects 27% of the heat of the sun due to the reflective properties of the polycarbonate. This means you can avoid the “greenhouse effect” that is an unfortunate side effect of glass secondary glazing, and enjoy a cooler home in the summer.

Helps contribute to a pollen free environment

InvisiTherm™ creates a complete seal over your windows, stemming the ingress of dirt, dust, pollution and pollen into your home. Old windows have multiple gaps and cracks where particles of pollen can make their way into the home. By sealing over the cracks with a secondary glazing system such as InvisiTherm™, pollen. dirt and dust ingress is virtually eliminated, leading to a cleaner home and better air quality. Perfect for summer hay fever sufferers!
