Committee:: PRI/72 - Rigid cellular materials
Categories:: Information management | Standardization. General rules | Cellular materials | Thermal insulation

Scope

BS 7457 specifies the property requirements, composition, and the production parameters of suitable PUR foam systems, which are dispensed on site, to fill the cavities of maximum width 150 mm of suitably constructed external walls of maximum continuous cavity height 12 m which have masonry or concrete inner and outer leaves.

Purpose

The specifications in BS 7457 help you to manufacture PUR foam systems to fill cavities that provide additional thermal insulation to walls and simultaneously, especially in the case of damaged wall ties, improve their structural integrity.
