uPVC Formulation
Our secret uPVC formulation and proprietary extrusion technology create window and door profiles with outstanding thermal performance of up to 35 percent better than other residential vinyl windows.

Compression-Seal Technology
uPVC frames and sashes and fusion-welded corners are combined with a sophisticated multi-chambered design and compression-seal technology. A minimum of three seals are co-extruded with each window and door profile for a welded fit that is incredibly tight.

Glazing Capability
REHAU windows and doors are designed to accommodate dual-, triple- and even quad-pane glazing up to 2”, which further helps keep warm air in on cool days, hot air out on warm days. With u-Values down to 0.13, this far surpasses the 0.37 u-Value of economy windows.

An optional upgrade is a Triplex glass, 2mm thick glass panes glued together, working as a car windshield. It offers extra impact resistance and security. Damaged glass won’t shatter, instead, it will crack, which keeps home temporarily secured until the window is replaced.

Thickness matters

positions devider - Frame Global86

All of our standard glass is no less than 1⁄6” thick, upgradable to 1⁄4” thickness for additional noise cancellation and durability.

I used Seemray to replace the windows in my living room as well as my kitchen, and they were great. They really know what they're doing and I finally have windows that are the real deal!

Very Happy

Through Seemray, we were able to replace all of the windows in our home with tilt and turn windows, and we couldn't be happier. The process was so smooth and we now have the windows we've been wanting for a very long time.

The Best Around

I was really excited to find Seemray since I had visited Germany several times and just loved their windows! They helped me get one step closer to my dream home. The windows are the best quality I have ever seen and they were very easy to work with! Would recommend to anyone in a heartbeat.

Overall, Seemray did a nice job replacing the windows and doors in my sun-room. I wasn't really sure what to expect, but was pleasantly surprised with the quality of the products and the work they did.

These windows are amazing! I really don't understand how they aren't more popular in America yet. Seemray replaced the windows in every major room of my house, and the difference has been incredible. My energy bills have dropped entirely and I know these windows will last!
