Hi Guys, I'm building a SIP garden office from a kit, I have the correct size French Door for the reveal, I've never fitted a door before and was looking for some advice. The door has come with instructions about how to properly configure them, but with no instructions about how/what to fix with specifically. * what would be suitable for screws for fixing the door to the reveal (it's wood)? * the door has a cil that needs to be screwed to the frame, what screws would be suitable for this? * also when fitting the door and cil to the reveal what should I just use silicone under the cil or do I need a pan or something else? Any help would be amazing - thanks in advance!
