I have to do this to 6 doors as part of a loft conversion. I knew I had to have 30 minute doors but never thought of the casings.
I just had a look at some in the builders merchants, they are a good 1" thicker than mine.
Am I going to have to have 2" smaller doors? The casings at the minute would fit a 762mm door.
Could I retro fit the intumescent strips to my existing casings or would that be like painting normal plaster board pink and calling it fire rated?
Cheers
