Kingspan Kooltherm® Cavity Closer (KKCC 75) is a 75mm uPVC insulated cavity closer with a premium performance fibre-free rigid thermoset phenolic core designed for closing cavities around masonry wall openings (England and Wales).

75mm Cavity Closer Kingspan Kooltherm is compatible with uPVC, timber, metal and composite window frames, suitable for use in both new build and refurbishment projects.

It provides a simple and efficient method of closing cavities around openings in masonry cavity walls, and has a thermal conductivity as low as 0.022 W/mK.

The thermally efficient insulation core inhibits heat transfer and thus reduces thermal bridging, whilst the uPVC casing provides a damp proof barrier.

Kingspan Kooltherm® Cavity Closer can reduce the risk of condensation forming at reveals and thus unsightly mould growth, which can lead to the deterioration of plaster, paintwork and wallpaper.

Using this premium performance product you will avoid problems commonly associated with the use of traditional methods for the closing of cavities.

Kingspan Cavity Closer provides a simple and highly effective method for closing cavities around openings in masonry cavity wall constructions in England and Wales.

The insulation component of the product shall be manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Cavity Closer Kingspan Kooltherm® Installation:

 · Cutting should be carried out using a fine toothed saw in such a manner that cross-sectional cuts are square.

 · Plaster or floor screed is applied directly to Kingspan Kooltherm® Cavity Closer as the section provides an effective key.

 · Where it is used in conjunction with a floor screed at a door threshold, the screed should be of sufficient thickness(65mm minimum) or reinforced to prevent cracking.

 · Plastering, the first coat of plaster should be pricked up into the keys on the Kingspan Kooltherm® Cavity Closer and then scored as a key for the next coat of plaster.

 · Dry-lining, the dabs for dry lining readily key into the Kingspan Kooltherm® Cavity Closer Fixing Oversailing Window Boards.

 · Window boards should be fixed in the conventional manner.

 · Direct fixing to Kingspan Kooltherm® Cavity Closer is insufficient.

 · Where an embedded tiled inner sill or threshold is required, the Kingspan Kooltherm® Cavity Closer profile provides a key for cement bedding.

 · On completion, the frame is sealed to the surrounding masonry and internal plaster in accordance with normal practice.

 · Kingspan Kooltherm® Cavity Closer is non-loadbearing and should not be used to support window or door frames, nor used in place of normal cavity wall ties.

 · Care must be taken when storing to prevent distortion of the sections.

 · Kingspan Kooltherm® Cavity Closer should not be exposed to excessive heat.

 · The packaging of Kingspan Kooltherm® Cavity Closer should not be considered adequate for outdoor protection.

 · Ideally, sections should be stored inside a building.

 · If, however, outdoor storage cannot be avoided, then the sections should be stacked clear of the ground and covered with a polythene sheet or weatherproof tarpaulin.

 · Sections where the insulation core has been allowed to get wet should not be used.

 · Kingspan Insulation products are chemically inert and safe to use.
