Applications

This 30mm ecotherm eco versal product works across new construction and thermal upgrade projects. Common uses include:

1. Floors
2. Pitched roofs
3. Cold flat roofs
4. Timber frame walls
5. Solid walls
6. Dormer cheeks
7. Ceilings
8. Room-in-the-roof applications

For floors | Moisture tolerance guidelines for Eco-Versal are as follows:

- The 30mm ecotherm floor insulation must be positioned above the Damp Proof Membrane (DPM) and kept away from ground moisture sources.

- Where concrete slabs are used, lay a protective membrane of at least 500 gauge thickness over Eco-Versal before applying the screed.

- Our 30mm Ecotherm PIR insulation works with most Underfloor Heating Systems (UFH). Install a minimum 500 gauge polythene sheet over the 30mm Insulation Boards before the UFH system. Refer to the UFH system manufacturer's guidance during installation.

For Walls | The guidelines for breathable membrane and vapour control when using 30mm ecotherm Wall insulation are as follows:

- Secure a breathable membrane according to the manufacturer's specifications.

- To reduce condensation risk, install a Vapour Control Layer (VCL) behind the plasterboard, unless using insulated plasterboard products.

For Roofs | Guidelines for using breathable membrane, vapour control, vertical battens, and insulation layers with Eco-Versal are as follows:

- Fix a Breathable Membrane as per manufacturer guidance. For pitched roofs, lay the membrane over the rafters and secure using tile or slate laths.

- Assess the need for a Vapour Control Layer (VCL) and/or undertile ventilation in line with BS 5250:2021 (Code of practice for control of condensation in buildings).

- For over-rafter applications, fix 30mm ecotherm Roof Insulation using vertical counter battens, which enable traditional slate and tile lath fixing methods.

- Lay the breathable membrane directly on the 30mm Eco-Versal board before installing counter battens. Alternatively, install counter battens on top of the 30mm PIR Board and drape the breathable membrane over them.

- Where lower U-values are needed, consider installing insulation between the rafters combined with Insulated Plasterboard such as Ecotherm Eco-Liner on the rafter underside.
