Description

Kingspan Kooltherm Cavity Closer is a cavity closer comprising a PVC-U extrusion with a premium performance rigid thermoset fibre-free phenolic insulation core.

Available in thirteen profile widths ranging from 50–150 mm. Jointing clips extend the range further by enabling sections to be coupled back-to-back, in order to suit cavity widths of up to 300 mm.

The casing incorporates tee projections along one plane length for the prevention of water tracking within the cavity, and fins along the widest plane length, which form an effective key for the direct application of plaster or screed.

Kingspan Kooltherm Cavity Closer PLUS is a pre–assembled frame, comprising cavity closer sections, fabricated off site, to accurately match specified opening sizes. Available in the same profile widths as Kingspan Kooltherm Cavity Closer.

The cavity closer is manufactured under a management system certified to ISO 9001: 2015 (Quality Management Systems. Requirements), ISO 14001: 2015 (Environmental Management Systems. Requirements), BS OHSAS 18001: 2007 (Occupational Health & Safety Management Systems. Requirements) and ISO 50001: 2011 (Energy Management Systems. Requirements with guidance for use).

Product Options

Accessories:

  • Curved sections: Comprise sections that are factory fabricated to suit any specified radius for specified radius for bullseye windows, curved heads, etc.
  • Fixing tie: Moulded PVC-U, white in colour, useful for wider cavities or in using sections to form openings, designed with different angled ends which slot securely between the tees at the ‘back’ of the section and keys fully into the mortar bed joint of the outer masonry leaf.
  • Jointing clip: Blue in colour, it connects two sections back-to-back along their length to suit cavities widths greater than for use in cavities greater than 150 mm wide.
  • Jointing strip: Grey in colour, it connects two abutting sections along their cross-sectional plane. It allows for opening sizes greater than 2.4 m and the reduction of wastage through the use of off-cuts. Limited to one butt joint per side of the opening.
