Fire Safety

We pride ourselves on delivering the safest products to our customers, we go through a rigorous testing phase to test our systems to destruction using independent test houses. We have been found to meet and far exceed compliance in every case. This is something we pride ourselves on, especially regarding the fire safety of our systems.

All of our products at Guttermaster hold either a A1 or A2 rating, giving them the ‘non-combustible’ Seal of Approval. This makes our systems perfect for all high rise developments above 18 meters. This is just another way we keep safety at the forefront of our business.

Fire Rating

Architects and Specifiers have an increasing number of considerations to satisfy when designing rainscreen systems to meet Building Regulations.  Aluminium fire rating performance is one of the most important factors today and the following summary has been provided to help in this endeavour.

Solid aluminium is classified as a non-combustible construction material.  Defined by BS476 part 4, aluminium alloys are non-combustible, part 7 Surface Spread of Flame ‘Class 1’ and part 6 Fire Propagation ‘Class 0’.  In addition, BS 476 part 3 covers External Fire Exposure roof tests and aluminium alloys are rated AA, the highest possible under this classification system.

Solid Aluminium is an obvious material choice, but some Architects might be wondering how the various finishes like polyester powder coating and anodising affect these impressive ratings.

Polyester Powder Coated Aluminium Fire Performance

Results from the Interpon D Fire test report for the performance of aluminium which has been powder coated, met the criteria for Class 0 building regulation approval.  The test report is available for download.
