Hi Therm Steel Cavity Lintels

Hi-Therm lintels are a smart choice when you want both strength and better thermal performance in one simple product.

Our hi-therm lintels are five times better than standard lintels at providing thermal performance, making them ideal for homes and properties where creating a comfortable indoor environment matters.

They can be placed above doors and windows to help reduce cold bridging, making them ideal for energy-conscious builds. Their clever one-piece design makes installation straightforward, while the built-in thermal break supports a warmer, more efficient structure, making them popular for modern builds.
