Rehau’s triple-glazed casement solution has a U-value of 0.8, and can be fabricated using Rehau S706 or Rehau Edge 70mm systems, without any special machining or tooling set up.
Rehau presents its triple-glazed casement solution with a U-value of 0.8, which can be fabricated using Rehau S706 or Rehau Edge 70mm systems, using proven off the shelf components and requiring no special machining or tooling set up.
The solution is based on Rehau S706 or Rehau Edge profiles with a triple-glazed Argon filled 44mm sealed unit. A standard bead from the Rehau range, which has been proven for many years with patio door panes up to 1200mm x 2100mm, accommodates the glass without compromising the clear sightlines of the window.
The open out casement window has been fully weather tested to 600Pa, has achieved security accreditation to BS7950, and is fully certified to the 0.8 U-value at the BRE standard window size of 1230mm x 1480mm.
The window also includes a new Rehau Thermo foam module which can be applied post manufacture or on site. Rehau Thermo was originally developed in Germany using a moulded foam material which is easy to handle and dust free when cut, and provides the additional thermal efficiency necessary for the window to achieve the 0.8 U-value. This simple and cost effective solution means that Rehau’s 70mm customers can now add a 0.8 triple-glazed window to their product portfolio.
According to Rehau, cost savings for this triple-glazed 0.8 U-value window over the conventional solution using a Krypton filled sealed unit are estimated at up to 50%.
