Heat protection

Comfortable indoor climate

At home, living spaces should stay pleasantly cool even in the summer. Direct sunlight can cause indoor temperatures to rise significantly. Here’s how you can provide effective protection for your living spaces from the heat.

Why rooms heat up

When sunlight hits glass surfaces, solar energy enters the building and is converted into heat there. Modern architecture with expansive glazing systems brings plenty of daylight into the interior, but at the same time, heat gain also increases.

External shading blocks the sun’s rays before they reach the glazing systems, thereby reducing the heating of interior spaces. Less heat inside the building helps keep the indoor climate comfortable for longer.

Effective heat protection starts at the window

Stop heat before it builds up

External shading blocks the sun’s rays before they hit the windowpane and can heat up the interior.

Shading Fabrics
Daylight instead of darkening

Fabric shades reduce glare and heat without completely darkening the rooms.

Less sunlight can reduce the need for air conditioning and cooling.

Heat protection with a view

Those looking for effective heat protection don’t necessarily want to sacrifice daylight and a view. Vertical fabric roller blinds reduce sunlight, provide glare-free light, and – depending on the fabric – still allow you to see outside.

This creates a pleasant atmosphere that feels brighter and more open than with fully closed shading systems.
