Promat TLFR Board®
There is an increasing requirement to upgrade the performance of semi-exposed concrete decks both in the conversion and refurbishment of existing buildings, and in new build constructions.
Promat TLFR Board® is a calcium silicate board bonded to Rockwool stone wool insulation and is designed to be fixed to the underside of concrete floors to achieve high levels of fire, thermal and acoustic insulation.
Suitable for underground car parks and similar applications, Promat TLFR Board® combines the benefits of Promat calcium silicate technology with Rockwool’s stone wool insulation to provide a cost effective insulation solution.
FEATURES & BENEFITS
- Up to 180 minutes fire protection
- Excellent thermal and acoustic performance
- Non-combustible facing board and stone-wool insulation
- Impact and moisture resistant
- Ease of installation, maintenance and decoration
- Ideal for new build and refurbishment
- CFC and HCFC-free
- Enhanced BREEAM rating

FIRE PROTECTION
Both the calcium silicate facing board and stone wool insulation elements of the system are non-combustible and have an A1 classification in accordance with BS EN 13501-1 and are noncombustible when tested to BS 476-4.
Promat TLFR Board® is tested in accordance with BS EN 1363-1: 1999 and ENV 13381-3: 2002 and provides up to 180 minutes fire protection to a structural concrete soffit.
THERMAL INSULATION
When fitted to a 150mm concrete soffit, 136mm thick Promat TLFR Board® allows specifiers to achieve a thermal insulation performance of 0.25 W/m2K, meeting Part L of the Building Regulations. The more stringent requirement of 0.20 W/m2K can be achieved using the 166mm thick board. Promat TLFR Board® uses Rockwool stone wool insulation.
EASE OF INSTALLATION
The Promat faced board offers an impact resistant surface which can be decorated to suit specific colour schemes. The stone wool core of the slab can be fixed to uneven surfaces without creating air-gaps which may affect thermal performance, while maintaining the aesthetic line and level of the ceiling.
ENVIRONMENTAL RATING
Rockwool’s stone wool insulation relies on entrapped air for thermal insulation properties and does not contain gases that have Ozone Depletion Potential (ODP) or Global Warming Potential (GWP). Promat TLFR Board® therefore complies with the relatively modest threshold of GWP <5 specified in documents such as the Code for Sustainable Homes.
