Planning to convert part of the attic into a new room. First, I'll redo the framing and insulate a bit. Then I wonder if I should use chipboard or drywall? Or maybe both? I like having chipboard to screw things into, drywall feels a bit weak... Maybe it's just something I've imagined. Can anyone offer tips?
My standard wall consists of a 45mm steel stud with insulation, followed by a 12mm chipboard and on top of that a 13mm gypsum board. The same on both sides, of course. You then have a wall that is 95mm thick and you won't have any problems with door frames, plus there is material in the wall so you can screw things up without too much hassle. Why steel studs then? Well, it's a few more kronor but not so much that it makes a huge difference. However, there are clear advantages as I see it, it's easy to run electricity because there are pre-made holes for conduits. They are STRAIGHT, unlike the 45x45 wood stud that everyone insists on. It's easy and smooth to build with, and so on. A little tip is that you can glue the gypsum to the chipboard, giving you a wall that is STABLE; overkill is also gluing the chipboard to the steel stud with an adhesive like PL400. If you need to make a hole for a door, I usually use 45x70 or 45x95 depending on my mood and what I have on hand. There are also pre-made brackets for the electrical boxes so you can mount them on the steel stud.
