WINDOWDRIVES - THE BLOG

We shot a short clip showing where the chain disappears to.

SHEVS in stairwells usually have to provide 1m² of geometric smoke extraction area. The question often arises as to how this is actually calculated. We investigate this topic and bring light into the darkness.

Here we explain the basic structure of screw drives.

We show you the design and operation of rack and pinion drives

Can electric drives be used in the bathroom? We are investigating this question.

In times of Homematic & Co. the question often arises, which parts are needed to automate window drives. The first thing to do is to define what "automation" actually means.

Tilt sash, turn sash, drop flap sash...

If you don't deal with these terms on a daily basis, it can be difficult to understand the descriptions or installation instructions for our drives. We have compiled the most common types of window sashes and provide a brief explanation for each design.

What actually needs to be measured and how? We show you what information is necessary to find the right drive.

What force does the drive need to open my window? What stroke length is required to achieve the desired opening angle?

These and similar questions inevitably arise when dealing with the retrofitting of windows and skylights with electric drives. We will show you formulas kindly provided by AUMÜLLER AUMATIC GmbH, Thierhaupten, and perform a few sample calculations.

It is not uncommon for us to hear in our consultations that the drives are to be installed in bedroom windows that are even to open or close the window in automatic mode during the night. This is just one example of how it makes sense to take a closer look at the issue of noise development.

We explain how chain drives are constructed and why the chain can push...
