Unilin (Xtratherm)

Unilin (previously Xtratherm) 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).

Additional features:

  • Saves Time
  • Cost effective
  • No cut return/Nib block required
  • Suits 100 - 150mm cavities
  • Meets new Part L requirements

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 set in the BRE Paper IP1/06 and asks that a value of 0.05 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 the traditional 25mm strip at the reveal.

However when pushing the wall U-Values to ‘A or B’ rated values the junctions actually fail IP1/06.

Unilin (previously Xtratherm) Close-R has been independently tested to exceed the new standards.

Installation information:

If precise fitting of windows can not 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 be extending by 50mm past the sill closer.

When sills are horned into the facing outer leaf, the reveal Close-R should be trimmed 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.

Specification Clause text:
