Product catalog summary
Introduction
Xtratherm Close-R is a high-performance insulation solution designed to close cavities around windows and doors, preventing cold bridging, damp penetration, air infiltration, and condensation. It is suitable for cavity widths from 100mm to 150mm and meets the new Part L requirements of the Irish Building Regulations.

Specifications
The Close-R system offers various U-value and Psi-value targets depending on the thickness of the insulation used. For example, a 60mm insulation achieves a U-value of 0.27 and a Psi-value of 0.006, while a 100mm insulation achieves a U-value of 0.18 and a Psi-value of 0.010.

Installation Guidelines
Precise fitting of windows is crucial, and a checked reveal with a vertical DPC is recommended if precision cannot be guaranteed. Close-R should extend 50mm past the sill closer, and horizontal DPCs should be used with the sill. For detailed installation guidance, Xtratherm Technical Support is available.

Building Regulations
The revised Part L emphasizes improved junction performance as wall U-values improve. Xtratherm Close-R exceeds these standards, ensuring continuity of insulation and reducing heat loss through non-repeating thermal bridges.

Product Range
The Xtratherm range includes various engineered components such as Partial Fill Cavity Wall (XT/CW T&G), Cavity Plus Enhanced Cavity Wall (XT/CWP T&G), Corner Panels (XT/CRN), and Thermal Liner (XT/TL & TL (MF)). These products are designed to enhance thermal performance and comply with enhanced construction details.

Technical Support
Xtratherm provides comprehensive technical support for designers and builders, with resources available on their website.
