Smart technology achieves greater energy efficiency for your home REHAU design significantly reduces heat loss and keeps out draughts. For excellent thermal properties and to achieve greater energy savings, REHAU S706 windows can easily achieve an A rating, the highest possible Window Energy Rating (WER) for thermal efficiency. The more efficient your home, the more you save.

All REHAU windows can achieve the minimum requirement, a C-rated Window Energy Rating (WER) and can therefore carry an 'Energy Saving Recommended' mark. REHAU windows and doors will comply with Part L Building Regulations providing the correct glazing unit is used. For windows this requirement is an overall U-Value of 1.6 W/m2K and for doors 1.8 W/m2K.

Air Leakage




The double glazed sealed units considerably reduce outdoor noise levels, allowing you to relax in the peace and quite of your home.

All REHAU 70mm profiles include multi chambers for improved thermal efficiency.

Larger reinforcement chamber - To allow additional strength/rigidity when necessary, a larger reinforcement chamber enables a range of galvanised steels to be inserted for optimum performance.
