REHAU S706 is a 70 mm depth PVC-U (uPVC) profile system for windows and doors, designed to replace traditional timber casement windows while offering modern performance, security, and styling.
Good thermal efficiency, especially when paired with triple glazing. Helps reduce heat loss.
Flexibility in style and appearance: lots of colour / finish options, both traditional and modern styling.
Security features built in, with profile designed to meet strong standards and ability to reinforce where needed.
Replace-timber ease: profile depth and styling make it easier to replace old timber windows without massive carpentry.
Durability / low maintenance: being uPVC, avoids many of the issues timber frames have (rot, warping, regular painting).
Regulatory compliance: designed with UK building regs in mind, so if you’re in a similar jurisdiction, many of the performance criteria should be okay.
