Kingspan TR26 Boards are Efficient - Suitable for Green Roofs!

If you’re looking for a thermally efficient insulation product for your green roof system, then our Kingspan TR26 boards are for you. Compatible with most green roof systems, TR26 boards are certified to BES 6001 (Framework Standard for the Responsible Sourcing of Construction Products) as “very good”, which makes them a reliable insulation board for green roofing systems.

Other flat roof insulation boards are available at UK Flat Roofing, including Rockwool Hardrock, TR27 by Kingspan and EcoTherm EcoDeck.





TR26 is a PIR, flat-roof insulation board that’s compatible with most green roof systems. With high-performance insulation capabilities, TR26 by Kingspan is a highly popular board used for thermal insulation.

There are lots of similarities between both boards, but the difference comes with what your roof needs.

Both are PIR flat-roof insulation boards, while TR26 is compatible with most mechanically-fixed waterproofing systems, TR27 can be used on roofs with waterproofed, fully adhered, single-ply and partially bonded cold liquid or asphalt waterproofing systems.
