3 Jul Curious how your findings compare to mine. At the sites I am currently surveying, the top three fail causes are:
1. Gaps too wide (over 4mm at head or jambs)
2. Missing or damaged intumescent strips
3. Self-closers not fully closing against the latch
What is topping your failure lists? And which ones are most frustrating to explain to building owners?
