Applications

This 75mm ecotherm eco versal board works well for both new construction and thermal upgrades to existing structures. Typical 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 75mm ecotherm floor insulation must be positioned above the Damp Proof Membrane (DPM) and should not be exposed to ground moisture.

- Where a concrete slab is present or specified, lay a protective membrane of at least 500 gauge thickness over Eco-Versal before applying the screed.

- Our 75mm Ecotherm PIR insulation works with most Underfloor Heating Systems (UFH). A minimum 500 gauge polythene sheet must be placed over the 75mm Insulation Boards before UFH installation. Always follow the UFH system manufacturer's guidance during installation.

For Walls | The guidelines for breathable membrane and vapour control when using 75mm ecotherm Wall insulation are as follows:

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

- To reduce condensation risk, fit a Vapour Control Layer (VCL) behind the plasterboard. This may be unnecessary if 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 following manufacturer guidance. For pitched roofs, lay the membrane over rafters and secure using tile or slate laths.

- Assess the requirement 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 all over-rafter installations, secure 75mm ecotherm Roof Insulation using vertical counter battens. This approach supports traditional slate and tile lath fixing methods.

- Lay the breathable membrane directly onto the 75mm Eco-Versal board before installing counter battens. Alternatively, install counter battens over the 75mm PIR Board and drape the breathable membrane across them.

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