Good day all.
Guilty of reading a lot of stuff on this site but never registering (i will try harder)
I was after a bit of advice if anyone has time.
I have a garden office (its a shed!) it lives on (70mm) pressure treated bearers on concrete base.
As it stands i am water tight and have doors and windows and even had time to do a spot of painting.
So my next step is to start thinking about insulation / air floor / damp etc.
My bearers currently run horizontal inside my shed.
all i can see inside floor of my shed is a concrete floor and the bearers.
So i figured i'd tell you my plan for the floor and you can pick it apart
I plan to build up a floor that will eventually have some form of laminate finish and include underfloor heating.
1.paint pressure treated bearers with wood preserver
2.use an anti mould sealant on the inside of the bearers where they make contact with the floor
3. seal the outside of the bearers that form the outside of the base with a water repellent sealant to keep anything creeping in under the shed from the outside.
4.put some form of insect mesh down between the rafters.
5. put nails (or something else) 5mm off the floor into the bearers to rest some insulation on and provide air space
6. install around 60mm worth of insulation (kingspan etc) foil backed.
7. Install a thin moisture/vapour barrier over the insulation (and the exposed top of the bearers
8. install a T&G 19mm floor
9 install a thin layer of insulation
10. install underfloor heating (foil based system i expect)
11. install laminate floor
Thats it - the reason for 2 floors is 1. to provide some strength and 2. i got the T&G floor with the shed so may as well use it.
My worries -
Air flow or not? is there much point sealing the outside of the bearers and inside with some sealant or do i let leave it open?
should any issues with the floor construction (eg ok to have a moisture barrier then a wood floor then laminate floor insulation (that will likely contain a moisture barrier) then the laminate floor?
Thanks in advance for any tips / help advice
