Colour protection is an important aspect when choosing glass, especially when sunlight exposure is a factor. This is because glass can act as a filter for harmful UV rays. These radiations can cause discolouration and fading of materials such as furniture, flooring and upholstery.

Ordinary float glass (uncoated glass) offers some degree of natural UV filtering, but special coatings and treatments can greatly improve UV protection. These coatings work by absorbing and reflecting a greater percentage of UV radiation, reducing the amount of UV radiation reaching the interior space and limiting the harmful effects.

Opting for a longer lifespan

By choosing glass with good colour protection, you can preserve the longevity and aesthetics of your interiors in addition to your own skin. Special coatings and treatments on glass can help reduce the passage of UV radiation while still allowing visible light to pass through.

Protecting colours in your interiors is important not only for maintaining aesthetics, but also for preserving the value of valuable objects, such as works of art and antiques. By investing in glass with colour protection, you can ensure that these objects last longer and retain their original beauty.

How much protection do I need?

Sprimoglass can block up to 99.9% of harmful UV rays, providing excellent colour protection. Our advanced glass solutions can offer even better protection, but it is important to note that these levels of protection are especially relevant for specific applications, such as museums and other environments where precious objects are displayed.

While maximum UV protection may not be essential for most households, it is still important to choose glass that offers good UV filtering to minimise discolouration and fading of interior materials.

What is UV radiation?

UV radiation, or ultraviolet radiation, is a form of electromagnetic radiation emitted by the sun. It is invisible to the human eye because their wavelengths are shorter than those of visible light.

Exposure to excessive UV radiation can have several negative effects, including skin burns, premature skin ageing, damage to eye tissue and an increased risk of skin cancer. It is therefore important to take appropriate measures to protect yourself from UV rays, such as wearing sunscreen, protective clothing and using sunscreen to reduce exposure to UV rays indoors.

Win-win situation!

When choosing a glass solution for colour protection, you also improve safety and quiet in your home at the same time. This is because the application of a protective film layer makes the glass layered, thus combining the benefits of different comfort points. You cannot see these properties of the glazing in isolation, properties of colour-protective glass also increase the safety values and acoustic values of the glass.

You can read more about these properties on the relevant comfort point pages.

Colour protection testimonial- Florence in her store

All our window items retain their punchy colours and look.

The window of our home-deco shop is always full of cool stuff. Colourful fabrics, Scandinavian-style wooden items... During the day, the sun shines hard on it for about five hours. Although we change the window every three to four months, we did notice that many items were discoloured. And that's a shame because our customers don't want that anymore. Since we got the new glass with extra colour protection layer... it's completely different. All our window items retain their punchy colours and look.

Colour protection testimonial- Iris smiling

Inside, it is still as beautiful as the day I moved in.

I actually didn't know that glass could protect the colour of my interior. It was the architect who recommended it because of our herringbone parquet and wooden stairs, and she was right! The glass has been protecting the colour and look of these elements, and all my paintings, in a great way for years now.
