Welcome to Timberweld®

  • Homeowners love the timber-look. So, the flush sash market is growing rapidly.
  • But how do you achieve the look of a traditional timber window, outside and inside?
  • And fabricate them cost-effectively at scale?
  • With perfectly sealed joints and high performance?

Here’s how…

Timberweld® is a patented method of jointing that creates a perfect butt-joint effect outside and inside the window for an authentic timber-look that is also cost-effective to manufacture at scale.

The Comparison

Timberweld® was designed for fabricating flush sashes as efficiently as standard PVC-U frames.

If you want to make a reasonable number of frames a week then you need to be equipped to do it efficiently and cost-effectively.

What are the benefits of Timberweld®?

Timberweld® is the best flush sash welded solution for technical performance, strength, aesthetics, suitability and economies of scale.

You can make them more cost-effectively with Timberweld® technology for a beautiful butt-jointed timber-look externally and internally. Timberweld is the only welded solution that makes a perfect welded timber-look outside and inside.
