S70 - PVC S Series

High soundproofing and resistance to crosswinds

Thermal insulation Uf

> 1,2 W/(m2K)

With S70 windows, energy consumption is reduced, which saves your expenses and contributes to the protection of the precious climate. This is clearly visible in the section of the profile: the multi-chamber construction of the profile with five chambers and an increased construction depth of 70 mm forms the basis for excellent thermal insulation. By using a circumferential stop seal and insulating glazing, thermal insulation values were achieved, which were practically unimaginable a few years ago.

New windows provide additional living comfort. Their construction and the materials used provide very effective protection against noise. In addition, the multi-stage seal retains the effects of wind pressure. And the optimal transparency of today’s insulating glass brings a lot of light intensity to the interior

This comprises of four compression roller pins, one latch and one dead bolt. All the locks on any one sash are operated by one lever and secured by one key.
