The non-setting putty is hand-workable, reusable and re-serviceable to ensure a tight fit and can be reshaped to other sizes and shapes if necessary. With 90 minutes of fire resistance in 100mm and 130mm dry wall constructions, intumescent putty is CE Marked and has been independently tested to EN 1366-3:2004 in conjunction with additional guidelines from BS:EN 1364-1 and has passed pair pressure tests up to 1000Pa.

Environmentally friendly and containing no solvents, the installation of the intumescent putty pads for electrical socket boxes also makes a significant contribution to the reduction of air leakage in properties helping reduce energy costs and carbon emissions.
