Unilin Close-R fully insulated cavity closers are a cost-effective solution for builders and specifiers for the closing of cavities around window and door openings, preventing cold bridging, damp penetration, air infiltration and condensation.

The Close-R range is used to close cavities and is suited to all types of windows and doors and is available in sizes to fit cavity widths from 100mm – 150mm, with checked detail to suit brick or drylined specifications and flanged detail to suit block outer facings (Flanged detailing requires precise construction tolerances).

Building Regulations:

The recently revised Part L of Irish Building Regulations places great emphasis on detailing at junctions. It has recognised the need to improve traditional junction performance as wall U-Values improve.

Targets for junction thermal performance are outlined in BRE Paper IP1/06, with a recommended value of 0.05 to be achieved.

In the past, where a typical wall U-Value was between 0.37 and 0.27, the 0.05 target was easily achieved using traditional 25mm strip at the reveal. However, when pushing wall U-Values to ‘A or B’ rated values, junctions can fail IP1/06.

Unilin Close-R has been independently tested to exceed the new standards.

Installation Information:
  • If precise fitting of windows cannot be guaranteed, a checked reveal using a vertical DPC should be used
  • Any jointing of Close-R should be facilitated within 150mm of the opening head
  • Close-R should extend by 50mm past the sill closer
  • Where sills are horned into the facing outer leaf, trim around the concrete sill and extend 50mm into the cavity
  • Horizontal DPCs should be used with the sill as normal, with a lining of 40mm Polyiso placed at the back of the concrete sill
