Applications

This 65mm ecotherm eco versal product works well for both new construction and thermal enhancement of existing building components. Its versatility extends to numerous applications:

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 65mm ecotherm floor insulation must be positioned above the Damp Proof Membrane (DPM) and should not be exposed to ground moisture contact.

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

- Our 65mm Ecotherm PIR insulation works with most Underfloor Heating Systems (UFH). A minimum 500 gauge polythene sheet must be placed over the 55mm Insulation Boards before UFH installation. Refer to your UFH system manufacturer's guidance during installation.

For Walls | The guidelines for breathable membrane and vapour control when using 65mm ecotherm Wall insulation are as follows:

- Secure a breathable membrane in accordance with manufacturer specifications.

- Install a Vapour Control Layer (VCL) behind the plasterboard to reduce condensation risk. This may be unnecessary if using insulated plasterboard.

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

- Fix a Breathable Membrane per manufacturer instructions. 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 according to BS 5250:2021 (Code of practice for control of condensation in buildings).

- For all over-rafter installations, secure 65mm ecotherm Roof Insulation using vertical counter battens, enabling traditional slate and tile lath fixing methods.

- Lay the breathable membrane directly on the 65mm Eco-Versal board before installing counter battens. Alternatively, install counter battens on top of the 65mm PIR Board and drape the breathable membrane over them.

- For applications requiring low U-values, consider installing insulation between rafters and using Insulated Plasterboard such as Ecotherm Eco-Liner on the rafter underside for improved performance.
