Kingspan TR24

The Kingspan Therma TR24 panel is specifically used on flat roofs and delivers high thermal performance when installed correctly. It is designed for use with partially bonded bituminous membranes, including torch-applied systems where specified.”

What is Kingspan Thermaroof TR24?

Kingspan Thermaroof TR24 is essentially a flat‑roof insulant. It features a closed‑cell PIR core faced on both sides with bitumen‑impregnated mineral glass‑tissue finished wth a polypropylene fleece. All three components are factory‑bonded.

This construction gives TR24 low thermal conductivity (as good as ~0.024 W/m·K, depending on thickness) and makes it well adapted for new and refurb flat roof systems.

What is Thermaroof TR24 used for?

TR24 Kingspan is primarily installed to insulate flat roofs, especially where the roof is covered with partially bonded bituminous waterproofing membranes (or similar systems).

It finds application on concrete, metal, and timber decks and existing flat-roof structures.

Developers, builders, and renovators choose TR24 for both new‑build flat roofs and re‑roofing projects.

Benefits of Kingspan TR24 insulation boards

Here is why installers choose TR24 insulation:

1. High thermal efficiency in a compact board. TR24 gives sound thermal insulation without excessive thickness. This helps prevent heat loss and boost energy performance in flat‑roof structures.
2. Strong, stable, vapour‑resistant PIR core. The closed‑cell centre resists moisture ingress but is not a substitute for a waterproofing layer.
3. Compatible with torch‑applied bituminous membranes. The bitumen‑coated facer and fleece finish make TR24 well-suited for torch-on waterproofing common to flat‑roof finishes.
4. Ease of handling and installation. The standard board size reduces joints. Plus, the boards are light enough and manageable on-site.
5. Versatile thickness range to meet different requirements (30mm-150mm). Ensures broad flexibility regarding thermal requirements, roof structure, and budget.
