the reason why we board the walls outside comes from roof issues that is known to roofers
at low apex's the material dropes and can fail due to heat in the roof
felt or plastic dropes with heat over time the roofing felt failed due to heat the newer felt or membraine is expected to do the same
build whichever suits you
ive advised on different types of shed builds
but you want 4x2s for walls and same for the roof 5x2 pref
but please do install a breathable membraine on outside it stops water getting in and allows moisture out
internal vapour barrier waste of expense to be honest...
wrong to a degree
the visqueen is a waterproof sheet will stop water getting through ( good point bad point wood behind cant breath or release moisture )
so correct in stopping water getting through to the framework
insulation bubble wrap tyvek breathable and scaff boards
really it means...
oh i can give you the architect side of it but you wont like the cost involved
cladding / batterns / membrane / plyboard / insulation / plyboard
however the plyboard imported isnt as strong as many might think it is Plywood is approximately 7% - 10% stiffer...
lets make it clear pir does not breath
materials made from petroleum products: phenolic foam, PIR, PUR and EPS. These offer broadly similar performance, and do not breathe, which is an important consideration for moisture control
you need moisture to leave from the internal woods in your walls...
your wrong even now
always work out from outside to the inside otherwise you can get it wrong easily
So its cladding, batten, membrane, osb, GAP, pir, then osb for your internal wall something to fix too
its the same as a roof as its the same for timber framed insulated wall
hes using it near a fire
paint on wood is bad enough even in the olden days the paint nowadays is better to a degree as long as he uses fire retardent paint
ive seen enough fireplaces burn or set a fire due to idiots and paint and materials too close to a fire wood stoves are much worse...
compared to 6 months ago everything has gone up
if you compare it to a year or 2 ago its more expensive now for materials and i dont think its coming down either
my advice adjust around what you can do and buy alternate if you have to do
the weather is an issue for start off
I can do joinery work dont think i cant the other person is the joiner not me
lugging stone slates off the roof with no lift isnt an easy job to do its very heavy work and 3 lifts keeping safety in mind weight on scaffolding is very important as it can...
well you know i have a chest issue but this has been done in 2 days
roof off from this stone slates then off the scafolding so its a triple lift even with 3 men on it
1/2 of 30 ft dormer done today from the previous pics above
felted and latted so waterprrof within reason for...
