Looking for Long-Term Energy Cost Savings?
Creating a building that is not only beautiful and comfortable but also highly efficient requires a total building design approach – one that answers questions like:

- What’s the effect of an increased window U-factor on the HVAC system’s load?
- How will a tighter building envelope impact the need for ventilation?

High-Performance uPVC Windows May Be Your Answer 
A design approach that views the entire building – the indoor climate controls and the building envelope – as a single, integrated system is your best shot at tapping into a huge potential for energy savings. Replacing older aluminum windows with uPVC windows, or specifying uPVC for a new construction project is an important first step in that approach.

Reduce Energy Use by 30%
uPVC window and door designs by REHAU are unsurpassed in thermal performance, allowing you to create building envelopes with large window-to-wall ratios that minimize energy loss while enhancing security, moisture and acoustic control. This will help you realize up to a 30% energy savings the first year and the next 20 years after that. With numbers like these, you're well on your way to tax incentives, green building certifications and long-term energy cost savings.

More Than 50 Years of Sealing in Sustainability
Since introducing our first uPVC window design more than 50 years ago, our fenestration solutions have been specified in thousands of new construction, replacement and remodeling projects around the world, delivering high-performance and years of lasting appeal.
