80mm EcoTherm Eco-Versal PIR Insulation Board

The 80mm EcoTherm Eco-Versal PIR delivers a comprehensive 5-in-1 performance solution with a rigid polyisocyanurate (PIR) core and aluminium foil composite facing applied to both surfaces.

This 80mm PIR Insulation Board works effectively for both new build projects and thermal upgrades to existing structures, offering a practical approach to lowering CO2 footprints and meeting Building Regulations/Standards requirements. The product's multi-purpose design makes it particularly suited to pitched roofs, floors, walls, dormer cheeks, and ceilings.

Applications

This 80mm product performs well across both new construction and thermal enhancement of existing building fabric. Typical 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:

- The 80mm ecotherm floor insulation should only be positioned above the Damp Proof Membrane (DPM). It must not be placed where ground moisture contact may occur.

- Where a concrete slab is specified or present, a protective membrane of minimum 500 gauge thickness must be installed over Eco-Versal prior to screed application.

- Our 80mm Ecotherm PIR insulation works with most Underfloor Heating Systems (UFH). A minimum 500 gauge polythene sheet must be laid over the 80mm 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 80mm ecotherm Wall insulation are as follows:

- A breathable membrane must be secured in line with the manufacturer's instructions.

- To mitigate the risk of condensation, a Vapour Control Layer (VCL) should be installed behind the plasterboard. However, this step may not be necessary if the plasterboard is an insulated plasterboard.

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

- A Breathable Membrane should be fixed as per the manufacturer's instructions. For pitched roofs, the membrane should be laid over the rafters and secured using tile or slate laths.

- The need for a Vapour Control Layer (VCL) and/or undertile ventilation should be assessed according to BS 5250:2021 (Code of practice for control of condensation in buildings).

- In all over-rafter applications, 80mm ecotherm Roof Insulation should be fixed using vertical counter battens. This traditional method of fixing slate and tile laths is made possible by the counter battens.

- The breathable membrane should be laid directly on the 80mm Eco-Versal board before installing the counter battens. Alternatively, the counter battens can be installed on top of the 80mm PIR Board, and the breathable membrane draped over the battens.

- In cases where low U-values are required, installing insulation between the rafters and using an Insulated Plasterboard like Ecotherm Eco-Liner on the underside of the rafters may be more practical.
