The Project 

The 200m2 Burley house was the first project to use the innovative L-Ments® system in the UK. Designed to offer U-values of between 0.13 and 0.19 W/m2K, it comprises breather membrane, counter battens and integral structural timber, along with high performance PIR insulation, all incorporated into lightweight cost-effective modular roofing panels. Such was the ease of application, the construction of the pitched roof was completed in just seven hours.

The Solution

L-Ments® is an innovative prefabricated roof system that enables the installation of a fully insulated pitched roof in just a
matter of hours.

  • Low thermal conductivity: 0.023 W/mK
  • Quickly waterproofs a partially built home, speeding up the construction process
  • Range of thicknesses: 145mm, 160mm, 180mm and 200mm
  • Five standard lengths: 5.4m, 5.7m, 6.0m, 6.2m and 6.5m
  • Can be covered with a range of finishes such as tiles, slates and zinc

The roof’s prefabricated element was key to its specification as I urgently needed to speed up building works on this project. I’m glad to say I made the right decision. L-Ments® is built for rapid installation as well as containing all the necessary thermal properties to ensure the completed house meets the near-zero carbon standard. Working with
the L-Ments® system proved to be a very good choice.
