Fire door between house and garage

[clairelouisecook]

I understand that I need a firedoor bwteeen my garage and the house. On the side of the garage there must be a 100mm step to prevent any fuel leaking in to the house and a closure and strudent strip on the door. Does the fire door need to be for one hour burning ie a 55mm door? Anything else I need to be aware of on the fire door in such circumstance.

what's a strudent strip?
do you mean intumescent strip?

also, what help do you think a bunch of electricians can be with regard to firedoors?

someone will be along shortly to move this to the correct forum...

see told you...

30mins is sufficient, it ought to have a self closer and should have intumescent strips fitted. Out of interest no longer need a 100mm step down provided the garage floor has a fall and it falls away from the link door.

The frame stops need to be 15/20mm too

sorry to be ignorant but does the frame stop mean that the door depth is 15/20mm as I am trying to understand if I need to get a new door architrave on the doors as well as what fire door I need to buy. Thanks for your help.

The frame stop is the bit the door closes against. In this link the stop dimension 15/20 as per woodys description is the 18mm dimension on this drawing: http://www.igdoorsltd.co.uk/illustrations/frame3.jpg

Yes that's it .... 18mm or 3/4" for the old guys.

I could not remember the dimension
