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 170mm ecotherm floor insulation must be positioned above the Damp Proof Membrane (DPM) only. Avoid areas where ground moisture may reach the board.

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

- Our 170mm Ecotherm PIR insulation works with most Underfloor Heating Systems (UFH). A minimum 500 gauge polythene sheet must be laid over the 170mm Insulation Boards before UFH installation. Refer to the UFH system manufacturer's guidance during installation.

For Walls | The guidelines for breathable membrane and vapour control when using 170mm ecotherm Wall insulation are as follows:

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

- To reduce condensation risk, fit a Vapour Control Layer (VCL) behind the plasterboard. 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's instructions. For pitched roofs, lay the membrane over rafters and secure using tile or slate laths.

- Assess the need 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 170mm ecotherm Roof Insulation using vertical counter battens. This traditional fixing method accommodates slate and tile laths.

- Lay the breathable membrane directly on the 170mm Eco-Versal board before installing counter battens. Alternatively, install counter battens on top of the 170mm PIR Board, then drape the breathable membrane over the battens.

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