Applications

This 45mm eco versal product works well for both new construction and thermal enhancement of existing building elements. Suitable applications 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:

- This 45mm 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, apply a protective membrane of at least 500 gauge thickness over Eco-Versal before laying the screed.

- The 45mm Ecotherm PIR board is compatible with most Underfloor Heating Systems (UFH). A minimum 500 gauge polythene sheet must be placed over the 45mm Insulation Boards before UFH installation. Refer to your UFH system manufacturer's guidance for installation details.

For Walls | The guidelines for breathable membrane and vapour control when using 45mm ecotherm Wall insulation are as follows:

- Secure a breathable membrane following the manufacturer's instructions.

- 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 as per manufacturer's instructions. For pitched roofs, lay the membrane over rafters and secure with tile or slate laths.

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

- For all over-rafter installations, secure the 45mm ecotherm Roof Insulation using vertical counter battens. This traditional fixing method supports slate and tile laths.

- Position the breathable membrane directly on the 45mm Eco-Versal board before installing counter battens. Alternatively, install counter battens on top of the 45mm PIR Board and drape the breathable membrane over them.

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