hanselosHello everyone,
I am still in the planning phase of my attic conversion. There are countless threads and helpful tips on this topic already, so thank you in advance.
We need an additional room under the roof. I plan to do most of the work myself and I am quite handy. The house is less than 10 years old. The attic floor is already boarded with tongue-and-groove boards, and there is insulation underneath. I need to install 20 cm (8 inches) of insulation between the rafters. My questions are:
1) I have read that the floor should be built with dry fill and then a dry screed. This sounds quite labor-intensive. What do you think? It should be quiet, as our bedroom is directly below.
2) I want to install an air conditioning system. I am considering mounting it on the pitched roof, but I am unsure how to get the pipes through the roof tiles. Can I simply push hoses underneath them?
3) I would like a multi-split system also for the first floor. The walls there are heavily insulated, and if I go through the exterior walls, I will damage the vapor barrier. How can this be solved effectively? The easiest option seems to be to direct the condensate water through the slopes to the roof and install the unit on the sloped ceiling. But how do I get the drain hose outside then?
4) Can I run the cables in the intermediate floor space, or is it always necessary to use the knee wall? This concerns both electrical and air conditioning lines.
5) For the staircase, I need to cut an opening longitudinally along 2–3 meters (6.5–10 feet) of the collar beams. Is it possible to install a beam replacement (header) this long, or is it structurally unfeasible?
I would appreciate any tips you can give me.
Thank you.
