Company Introduction

The Siderise Group is one of the UK’s leading manufacturers of fire, acoustic and thermal insulation products, and has been for over 40 years.


The Group has two factories based in Maesteg, Wales and Hadleigh, Suffolk, and operates across 11 global sectors. The SIDERISE product ranges have become trusted throughout the facades, construction, interiors and HVAC sectors.


The Group is committed to the use of innovative materials and the development of designs, products and technologies for a more sustainable future. In 1991 the Siderise Group developed a unique method of mineral wool manufacture, the patented ‘HSL process’. This process gives firestopping and other products a robustness and simplicity of design that meets all functional performance requirements and facilitates superior product installation. This unique design has positioned the Group’s firestopping solution as the UK’s No.1 for the curtain walling industry for over 25 years.


The Group’s sale and distribution activities are prevalent in Ireland, across Europe, the Middle East, India and South East Asia.
