Which rules apply in Scotland?
Scotland Which rules apply?
In Scotland, building work needs a building warrant under the Building (Scotland) Regulations 2004, with fire guidance in Section 2 of the Building Standards Technical Handbooks rather than Approved Documents.
For relevant premises, the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006 place duties on the duty holder to maintain fire safety measures, which include fire-resisting glazing.
Scottish guidance has its own approach to escape routes and compartmentation, so glazing designs are checked against the Technical Handbooks and the warrant drawings.
FAQs for Forth Valley
Why is insulated fire glass so much more expensive?
It is a multi-layer product with specialist interlayers, and the frame and installation must suit its weight.
What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
Can you survey anywhere in Forth Valley?
Yes. We can arrange surveys anywhere in Forth Valley, including Stirling and Falkirk, Alloa.
