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.
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.
