Pro-Versal - Floor Insulation

PrO-Versal is a rigid, high compressive strength insulation board, ideal for insulating floors. PrO-Versal boards are part of EcoTherm's enhanced performance range with a improved thermal performance and Class O fire performance providing an even thinner solution for floor insulation when compared to standard PIR.


Suitable for use in new build or upgrading the thermal performance of existing floors, providing a cost effective means of reducing CO2 emissions and compliance with Building Regulations/Standards.

PrO-Versal provides the idea solution for insulating:

  • Solid concrete floors (above and below slab)

  • Block and beam floors

  • Suspended timber floors

  • Underfloor heating systems


EcoTherm PrO-Versal comprises a fibre free rigid polyisocyanurate (PIR) insulation core with pure aluminium foil facing on both sides.

Standard Dimensions

Length: 2400 mm
Width: 1200 mm
Area: 2.88 m2
Thickness: 25 - 120mm

Thermal Performance

The thermal conductivity (lambda / λ value) of PrO-Versal is 0.021W/mK

The typical compressive strength of PrO-Versal is 140 kPa when tested at 10% compression to BS EN 826: 1996 Thermal Insulating Products for Building Applications – Determination of Compression Behaviour.

For detailed product and application information please download the PrO-Versal datasheet

PrO-Versal benefits:

  • Class O fire performance

  • Lower lambda value of 0.021W/mK means even less thickness is required than standard PIR

  • Out performs traditional insulation materials by 50% - you only need half as much

  • Excellent thermal performance - meet Building Regulations/Standards with minimal thickness

  • Rigid boards are easy to lay, cut and install

  • Excellent compressive strength when compared to traditional forms of insulation

PrO-Versal can also be used to insulate pitched roofs and walls
