Alumasc External Wall Insulation and Renders Systems – UK Manufacturer

Alumasc is a UK manufacturer of External Wall Insulation and Render Systems.  Based in St Helens, Merseyside the Company employs a workforce of over 50 people consisting of both production and back-office support staff.  Providing local employment to both experienced employees and apprentices, the Company is committed to the provision of the highest quality products and systems, with stringent quality control and environmental procedures firmly in place, to ISO 9001:2008 and ISO 14001:2004 respectively.


Alumasc’s render manufacturing facility achieves less than 1% manufactured wastage and is examined annually by an independent auditor to ensure full compliance with all legal requirements regarding health and safety, noise and air pollution, thus providing a safe working environment for our employees and zero impact on the lives of local residents.

Controlled production of consistent, quality materials supplied to every Alumasc site across the UK ensures first-rate application of the Company’s products. A national network of registered, Alumasc-trained specialist contractors deliver superior, efficient installation of Alumasc’s BBA approved External Wall Insulation systems time after time.

For added peace of mind Alumasc has a Quality Control laboratory at St Helens, allowing standard testing of all products produced prior to release for despatch to the customer therefore guaranteeing suitability for purpose. 1kg samples of render material produced are retained on site of every 5th tonne manufactured during the working day and held in quarantine for up to 2 years.  This ensures that if, in the unlikely event of a system failure, Alumasc can analyse the retained sample of that product and swiftly provide advice, and ultimately a positive resolution for our customers.

Alumasc’s wide range of External Wall Insulation systems is available with some of the longest accredited BBA certificates in the industry.  The Company is proud to be one of the very few UK based manufacturers of External Wall Insulation and Render Systems.  If you are interested in any of our products, please Contact Alumasc on +44 (0)1744 648400 or email
