The ESSMANN HDS protection system is the ideal complement to all standard arcade rooflight systems. It consists of an external perforated aluminium sheet covering that is fitted onto the arcade rooflight profile, with a gap between the two.
The acronym HDS is derived from the German names of the three main functions offered by this product:
H = Hagelschutz (hail protection), D = Durchsturzsicherheit (fall-through protection) and S = Sonnenschutz (sun protection).
The perforated aluminium sheet of the HDS system provides the arcade rooflight systems underneath it with the best possible protection and prevents the rooms below from heating up. The structure of the sheet, combined with the movement of the sun over the course of the day, creates a constantly changing pattern of light and shade. Furthermore, the gap of around 60 mm between the perforated HDS protection and the surface of the glazing provides good air circulation and prevents heat from accumulating. The dappled effect created by the natural shade that filters through the arcade rooflight systems not only looks fantastic, but also offers excellent protection against the sun.
Other benefits provided by HDS protection: - Glare protection
- UV protection
- Protection against pollution
- Good absorption of the noise generated by rain and hail
- Soundproofing
- Intruder resistance
The ESSMANN HDS protection system can also be retrofitted onto all standard arcade rooflight systems (arched arcade rooflights, saddle rooflights, pyramid structures).
