Kingspan Insulation Boards

Celotex FI5000 is one of the latest additions to the Celotex insulation range. This is a high performance PIR insulation board designed for flooring insulation applications, Celotex FI5000 has a unique facing incorporating a vapour control layer allowing for direct screed pour and negating any affects caused by screed contact as other foil faced boards would have when not covered with a damp proof membrane.

The Celotex FI5000 innovative design takes over where Celotex FF4000 left off taking the PIR insulation market into the future with a high thermal performance giving a low thermal conductivity of just 0.021 W/mK as well as a hugely immpressive compressive strength of >175kPa making it the best in class for compressive strength at the time of writing.


Celotex FI5000 can be used in many underfloor applications such as under screed floors using block and beam flooring systems , underslab concrete, suspended timber flooring applications and is an ideal answer for use with underfloor heating as the structure of the foam enables improved underfloor heating pipe clip retetion.

As with all Celotex products the FI5000 is made using blowing agents with Zero ozone depletion potential and that along with a low global warming potential. so you know when your purchasing Celotex insulation you are using a product made with the environment in mind. The Celotex FI5000 range comes in board sizes of 2400x1200 and in thicknesses of 75mm, 100mm and 125mm and the Celotex US4000 board should be used for perimeter upstand insulation available in 2400x1200x25mm boards.

Celotex FI5000 and US5000 can be ordered into stock in pack quantities and are usually available within 4-5 working days.
