Cavity Closer XPS

The Mayplas Cavity Closer range is manufactured from an insulant core with a PVC-U rigid extrusion which reduces thermal bridging and forms a damp proof barrier.

Features and benefits:

• PVC-U outer acts as a damp proof barrier.
• Insulated core reduces thermal bridging.
• Helps prevent condensation, staining and mould.
• Easy to install.
• Minimal wastage during construction.
• Lightweight.
• Cavity widths: 50–150 mm.

CHECK REVEAL LOCATIONS

Single flange is primarily produced for check reveal applications. Guidance documents, such as NHBC Standards and The Building Regulations Approved Document C specify locations where check reveal applications are required.

FLUSH REVEAL LOCATIONS

Double flange is more commonly suited to flush reveal applications, which allows a varying window position.

THERMAL PERFORMANCE

Accredited Construction Details and Enhanced Construction Details require a minimum thermal resistance path through the cavity closer of 0.45 m²K/W. All versions of Mayplas Cavity Closer will contribute toward overall compliance.

THERMAL CONDUCTIVITY

Mayplas Cavity Closure XPS 0.033 (W/mK).

WEATHER EXPOSURE

The Mayplas Cavity Closer range provides options for either single or double flange solutions to address check or flush reveal types, respectively.
