Timber Frame Party Wall System

Timber Frame Party Wall System

The ARC fire stopping party wall system for timber frame construction.

The ARC Timber Frame Party Wall System is an innovative fire-stopping solution at the party wall of terraced and semi-detached timber frame low-rise buildings.The System is made up of of eight individual components ARC products all working together to designed to stop the spread of smoke and flames within unseen cavities at the party wall.

Key Benefits Of The ARC Timber Frame Party Wall System

  • Where appropriate, key products in the System exceed fire integrity requirements laid out in Approved Document B (ADB).
  • Satisfies NHBC Chapter 7.2 D13 ‘Junctions between roofs and compartment or separating walls shall adequately resist fire spread’.
  • Supports compliance in the new 2024 guidance laid out by NHBC.
  • Key products are third party certified by IFC.
  • A far more effective fire-stopping solution than conventional systems.
  • Supports an excellent U-value, reducing energy bills.
  • Complies with Robust Details.

Reducing Heat Loss & Energy Bills

Apart from its life-saving fire-stopping features, the Party Wall System also boasts a remarkable reduction in potential heat loss. The ARC Timber Frame Party Wall System significantly minimizes heat loss along the edges of the party wall, resulting in an impressive U-value. In the absence of effective edge sealing, heat tends to escape through the party wall cavity, increasing energy bills.

The illustration below underscores the areas susceptible to heat loss in a row of terraced houses, particularly emphasizing the heat loss at the top junction where the party wall cavity meets the external cavity. The Timber Frame Party Wall System effectively tackles this heat loss issue, contributing to a higher EPC rating and working to lower energy bills.

Further Benefits Of The ARC Timber Frame Party Wall System

  • Up to three times more effective as an edge seal than conventional systems.
  • Simplified installation when compared to conventional systems.
  • Reduces sound transmission between the dwellings and within the cavity.
  • Minimises thermal bypass.
  • Specifically designed for timber frame low-rise constructions.
