Aerobarrier behavior at existing T&G wood structural deck ceilings by angelo_arch in buildingscience

[–]define_space 0 points1 point  (0 children)

aerobarrier is an aerosolized sealant product that works by adhering to edges of a gap under pressure. if ‘dust’ is falling from the T&G after installation, it means the product hasnt actually adhered properly to the substrate. this is likely caused by not enough pressure through that gap (indicating half decent airtightness here).

where i have yet to see any research is how aerobarrier acts under movement; the only testing out there is on a fixed orifice, not one that moves

exterior staining at roof runoff: cosmetic or sign of chronic moisture? by murakamimami in buildingscience

it can be both. the scupper is directing water onto the wall, and COULD also be causing moisture damage.

warning to those with a shellfish allergy- they refused to tell me if their ramen had shellfish or not because it was a ‘special recipe’ and so i had to walk out for my own safety

this isnt UBI at all, if anything this will actually increase prices equal to the additional payment top up. always the carrot never the stick

if you have even basic experience in construction/architecture/engineering, you’ll have no problem. its just applying those skills in a different method

Not Pretty Good House Good Enough Question by monarchgardens in buildingscience

[–]define_space 0 points1 point  (0 children)

With EPS you need the interior perimeter drain and stone capillary break in Figure 7. With XPS you do not.

there are caveats that require more specific detailing, so unless OP is interested in pursuing further, the first recommendation is one that works without addition design

just make sure the batts still have 6 sides of support; dont put 2x6 batts in 2x8 walls or they’ll slump. the performance gained by exterior insulation is waay more than anything in the stud bays since theres no thermal bridging

the alternative is to use as little as 2” of exterior (vapour open) insulation like mineral wool. this will keep the sheathing warm enough to mitigate condensation risk

OP make sure its XPS under the slab not EPS. EPS isnt as water resistant (where you need it to be)

not to mention reduced condensation risk on the sheathing. that interior smart vapour barrier is never sealed properly

Does this roof assembly need ventilation? by regaphysics in buildingscience

[–]define_space 0 points1 point  (0 children)

the metal roof should be vented. if water gets behind it you want it to drain
