I'm about tot start building the new floor in a loft conversion that I'm working through this year. I'm looking at options for UFH at the moment as I don't want to buy/fit anything that causes problems if I go that route wit the heating.
I've tried my best Google skills, but it's a bit of a niche installation, so looking for experience and ideas for the most suitable system for my situation.
The new floor is 145mm joists, sat 14mm clear of the existing ceiling joists. The design has the new floor level running across the top of the bottom chord of the existing King Truss because the easiest build method is if that chord stays where it is, which leaves that 14mm gap.
A between joist setup would be best, but the structure of the floor means there's a strip of joists between steel where there isn't easy pipe access from the side of the room. I've attached a sketchup image that shows the steel running front to back and the steel-flitched king-truss bottom chord, with the joists running between.
I can cover that area by drilling the joists, or the steel, or going under the joists, but I guess the easiest approach depends on what kits are designed to accommodate this situation. Eg, I can't go under the joists if someone doesn't make a shaped link pipe or similar.
I can go over the top of the new floor, but would prefer to avoid adding height and would that need chipboard over the joists, UFH on top of that, then another layer of chipboard?
So, what's the best way to get UFH into this space, what are my options, what should I look at etc?
Thanks!
