For sealing the top of the party wall cavity between blockwork and spandrel panel.

The Spandrel Barrier is designed to be fitted across the top of party wall blockwork underneath a timber spandrel panel. Installation is straight forward: 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 should be butted tightly together, with care taken to ensure that no gaps remain.

It 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. The barrier is compressed between the top of the party wall blockwork and underside of the spandrel panel, creating a fire and thermal break.

Features and benefits:

• Up to four hours' fire integrity around edge of party wall.
• Up to one hour's fire integrity between the spandrel panel and blockwork.
• Use in conjunction with ARC T-Barrier® vertically to create an effective edge seal around the party wall cavity.
• Zero U-value can be achieved.
• Minimises thermal bypass.
• BRE Green Guide 'A+' rating.
• Manufactured under ISO 9001- and ISO 14001-certified 'Quality and Environmental Systems'.
