ARC SPB100/100 Spandrel Barrier 100mm Cav 120/100x25/200x1.2m

Arc Spandrel Barrier for 100mm Cavity Widths

ARC Spandrel Barrier seals the top of the party wall cavity, allowing a zero U-value to be achieved when used in conjunction with ARC T-Barrier vertically. Spandrel Barrier is compressed between the top of the party wall blockwork and underside of the spandrel panel, creating a fire and thermal break

Installation

ARC Spandrel Barrier is designed to be fitted across the top of party wall blockwork underneath a timber spandrel panel. Installation is easy, the barrier simply push fits into the top of the party wall cavity. The spandrel panel then drops on top, compressing the barrier and creating a fire and thermal break between the spandrel panel and blockwork. Lengths of ARC Spandrel Barrier should be butted tightly together, with care taken to ensure no gaps remain.

Fire Properties

ARC Spandrel Barrier is manufactured using rockfibre mineral wool which achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1. ARC Spandrel Barrier has been fire tested at Warrington Fire
Research, achieving up to four hours fire integrity in masonry party wall cavity, and up to one hour between a timber spandrel panel and the top of party wall blockwork. These tests comply with BS 476: Part 20: 1987 and BSEN 1366-4: 2006, using the test method stated EGOLF TC2 N421 (fire resistance
for cavity barriers).

Warrington Fire Research certificate number: 189654
Chiltern International Fire certificate number: 10039

Standards

ARC Spandrel Barrier is manufactured using rockfibre mineral wool which achieves a fire classification of Euroclass A1 as  defined in BS EN 13501-1, and conforms to BS EN 13162 and EN16001 Energy Management Systems. ARC’s rockfibre mineral wool insulation has a thermal conductivity of 0.037W/mK.
