My Shed build

[Joe Shmoe]

Hi all.

Shed is almost complete, but now I wanted to put insulation in the wall (I used 2x3 so have 75mm cavity) and then line the inside with something.

Can any help with these questions?

1) I installed a membrane between the studwork and the exterior shiplap, but do I need some kind of second membrane in between the insulation and the inside lining of the shed ?

2) what kind of insulation material should I use?

3) What should I line the walls with ? Should I get some cheap interior cladding (but will I need to treat it?) or should I get some OSB or something?

Hi joe

after much research and various opinion i have the same questions as to what to construct the walls from ie insulation etc

i have decided on 3x2 frame, cladded on the outside with a 6mm sheathing ply then breather membrane stapled to that - battons for air flow then ship lap -

on the inside 40mm kingspan / visqueen membrane to stop any moisture coming back then 12mm wpb ply for the interior walls -

some say this is over the top - anyone have any ideas?

i need it to be bone dry no moisture at all.

Into the guttering.

DO NOT LET THE BREATHABLE FELT HANG INTO THE GUTTER.

It soaks up the water like a sponge, you normally use a 12 inch wide strip of slaters felt on the roof to hang into the gutter, then breathable felt under the roof covering so it can't be seen. If it is to late for that then cut of the felt under the tiles flush with the facia.

Granted keep it above the water level, I've always found that ordinay felts even rot if right into the gutter. They also trap leave as well.
