At Firth Sheet Metal Ltd, we offer the entire package: design, manufacture, insulation and installation, along with commissioning. We comply with the industry standards and adhere to building regulations and go above and beyond to ensure we are environmentally friendly. Our ISO9001 certificate ensures we are quality conscious throughout the business and maintain a thorough checking procedure from concept to completion.

We are a proud manufacturer and supplier of Flameshield Fireduct, the UK’s first non-coated, fire rated ductwork which achieves LPCB certification for both BS & EN Standards. Certified to provide up to 2hrs of fire resistance, it helps to contain fire and smoke spreading through ductwork penetrations in walls and floors. Its use is detrimental in commercial and high-risk areas like hospitals, care homes, hotels, shopping centres and other large public buildings, where means of escape such as stairwells and corridors need to guarantee integrity.

We offer the full system for kitchen and steam extract systems, from the canopy through to the cowl and everything in between.

Kitchen and steam extract are essential systems within the kitchen environment, preventing fire hazards, removing pollutants, eliminating odours, reducing heat and humidity, and furthermore protecting properties from attracting mould and condensation.

What is DSEAR…?

DSEAR stands for the Dangerous Substances and Explosive Atmospheres Regulations 2002. It is a UK legislation that requires employers to assess and manage the risks of fires, explosions, and similar energetic events caused by dangerous substances. What is ATEX…?

ATEX in ventilation refers to the requirement for ventilation systems and components such as fans, ducts, and motors to be specifically designed and certified for safe use in potentially explosive atmospheres. We work with several large refrigeration companies for ammonia extraction ensuring compliance is achieved.
