Recticel EuroWall PIR

Recticel EuroWall is a PIR board for partial-fill cavity walls. It is fixed against the inner masonry leaf while a clear cavity remains outside the insulation.

Use it when the wall design calls for partial fill rather than a full-fill product. The residual cavity, wall ties and retaining clips are part of the construction, not optional extras.

Keep the board faces clean, close joints tightly and prevent mortar collecting on exposed edges.

Why Choose This Product?

Choose this only when it matches the cavity strategy on the drawing. Full-fill and partial-fill boards are not interchangeable; the board facing, joint detail and required residual cavity are different.

Key Features

·        PIR partial-fill cavity board

·        1200 x 450mm boards

·        Foil facings

·        For masonry cavity walls

Common Uses

·        New-build cavity walls

·        Extensions

·        Masonry wall thermal upgrades during construction

Installation

Cut boards or rolls accurately, close every joint and keep the insulation layer continuous at corners, openings and service penetrations. Use the fixings, tapes, membranes and covering layers stated for the selected construction.

Before You Install

·        Mixing up full-fill and partial-fill products.

·        Selecting a thickness without checking cavity width and the required residual cavity.

·        Leaving open joints or mortar droppings on board edges.

·        Using the wrong retaining clips or wall-tie detail.

Frequently Asked Questions

Is this full fill or partial fill?

Use the application stated in the title and technical description. Do not substitute one cavity strategy for the other.

Can I cut cavity boards?

Yes. Cut cleanly and keep the facing intact. Small pieces should remain firmly retained.

Do the joints need taping?

Follow the named cavity system. Most masonry cavity boards rely on tight joints and correct retaining details rather than ordinary foil tape.

How do I calculate quantity?

Divide the wall area by the coverage per board or pack, then allow for cutting waste and openings.

Can it be used in an existing wall?

Rigid cavity boards are normally installed as the wall is built. They are not injected into a completed cavity.

What You'll Need

·        Correct wall ties

·        Insulation retaining clips

·        Cavity closers

·        Cavity trays and stop ends

·        PIR cutting saw
