Weep Vents

[Shytalkz]

I did: I said that Nose was spot-on with his explanation as to the BRegs requirement for a cavity tray.

Answer my questions re single skin houses. It may be a requirement - but that doesn't prove what it is supposed to do.

As with a lot of things BRegs-wise, it's a sledgehammer to crack a nut and largely superfluous in many instances - exposed areas subject to driven rain would be an exception. But, regardless of its efficacy or even its necessity, the reason for its inclusion is as per Nose's comments.

the simple fact is joe, despite b'regs, is you were way off the mark on this one laddie.

in case your wall plate at roof level allows the ingress of water into the cavity. In normal circumstances the weep vents don't actually do anything.

can you please explain what you meant here please joe?

Yes certainly. I meant:

"In case your wall plate at roof level allows the ingress of water into the cavity. In normal circumstances the weep vents don't actually do anything."

No way - it's you that thinks he know - but is wrong. Houses with fresh pointing don't leak. You've admitted that yourself.

how does a wall plate admit water?

I'm referring to the wooden structure that runs around the top of the wall above the cavity that the roof joists and rafters sit on.

 

[Shytalkz]

By capillary action - or vicious fingering, possibly

[Shytalkz]

Yep, to stop all that nasty air going stale in the cavity and making the house smell

Have you ever seen any weeping?

Have you ever seen any sarking boarding being witty or jocular? Roofing felt made out of green soft and fuzzy stuff? BAT straps flying around in the evening and leaving half-eaten butterflies on the bedroom floor?

weep vents are designed to work during heavy and prolonged periods of wind driven rain. it would be hard to discriminate between ejected water and rain droplets.


regardless of all your windy bluff joe, the purpose of weep vents is clear.

and you are wrong laddie.

Have you never been on site during heavy rain while construction is in progress !! can assure you it aint air that comes out of them. Surely the name gives it away "weep holes" or should they be called " cavity vents" maybe we should rename air bricks and call them weep bricks.

i suppose thats why dpc is put at the bottom of the wall as well to stop the rain from leaking roofs getting into the foundations
