How we work in Preston
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.

Honest about unknowns
If an existing frame in a Preston building has no traceable evidence, we say so and price the options rather than guess.
Key checks for Preston projects
Thickness and weight
Each step up in rating adds layers, so EI 120 is far thicker and heavier than EI 30. The frame has to be designed for it.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.

In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
