The UK leader in Stud Welding and Refractory products
WDS® Microporous Insulation Boards and Panels are a range of advanced thermal insulation products engineered to deliver exceptionally low thermal conductivity in applications where energy efficiency, reduced heat loss and compact insulation design are critical. By minimising heat transfer through conduction, convection and radiation, WDS products provide thermal performance significantly superior to conventional high-temperature insulation materials.
Designed for demanding industrial environments, the WDS range combines high thermal stability, excellent handling characteristics and reliable long-term performance. Available in rigid board and panel formats, WDS solutions help maximise energy efficiency, reduce insulation thickness and create valuable space savings across a wide range of thermal processing applications.
With specialised grades optimised for thermal conductivity, compressive strength, dimensional stability and moisture resistance, WDS products provide tailored insulation solutions for industrial furnaces, petrochemical processing, energy systems and advanced thermal management applications.
WDS products deliver exceptional thermal performance where space constraints, energy efficiency and operating temperatures demand advanced insulation technology.
