GaryM Posted February 8, 2021 Share Posted February 8, 2021 I'm putting timber cladding on the outside of a concrete block wall. The Building inspector has told me I need to put an breathable membrane on the blocks. So simple question how best to attached it? This may sound daft but I don't want to batten it to hold it on as I'm going to prefabricate cladding panels and the battens will be part of the panels, I will then fix the whole panel with concrete screws to the block wall. So I really only need to hold the membrane in place until I put the panels on which will hold it all in place. Thanks Gary Link to comment Share on other sites More sharing options...

Iceverge Posted February 8, 2021 Share Posted February 8, 2021 (edited) Attach the breather membrane to the back of your panels with the appropriate overlap in place. Take care when installing that you get your overlaps right. Edited February 8, 2021 by Iceverge Link to comment Share on other sites More sharing options...

Good Question. to keep building control happy I guess it to stop water ingress, the cladding is open joint so air can circulate, but it is in an exposed area where we can get near horizontal rain, so in the long term it will help to protect the blocks are just 3.6 lightweight blocks Link to comment Share on other sites More sharing options...

It's a concrete block cavity wall, I think in principle we may get away with not putting a membrane on, but our building inspector has requested one. It will be viewable through the open joint cladding, so I think I will go for the powerlon 160 Uv membrane, it has a very long lift time. Link to comment Share on other sites More sharing options...

Don't choose a windy day. Get the cladding on soon after. A lot of the better membranes have tapes to join which will also help keep it in place. 1 Link to comment Share on other sites More sharing options...

I'm going to the cladding a different way to what I was originally intended, so now we can use vertical battens, so all good.

SteamyTea Posted February 15, 2021 Share Posted February 15, 2021 With all the fuss about flammable cladding on buildings, is it really worth doing if you want to resell. It does not matter what the rules say you can and cannot do, it is the toxic element in the buying publics mind that counts. Link to comment Share on other sites More sharing options...

George Posted February 17, 2021 Share Posted February 17, 2021 If you've got an architect handy you could ask them to write a short letter to the BC about the pointlessness of a breather membrane on a cavity wall. Link to comment Share on other sites More sharing options...

mattdeluca Posted January 12, 2022 Share Posted January 12, 2022 Hello all, relighting and old thread, I have a similar scenario and need a bit of advice. I am applying cladding to my concrete block garage as the wet weather is seeping through the blocks. The main garage wall is west facing and takes the brunt of the rain and then small beads of water can be seen on this inside of the wall. A question about the membrane, can it be applied directly to the block wall and then batten on top or does it have to be attached/stapled to batten? i.e. wall - batten - membrane - batten - cladding or can it be wall - membrane - batten - cladding I don't really want to double up on the battens as it will cause a further protrusion. Thanks in advance, Matt Link to comment Share on other sites More sharing options...
Mr Punter Posted January 12, 2022 Share Posted January 12, 2022 Hi @mattdeluca and welcome. You can just fix battens to the wall. No need for membrane.. If you are desperate to use some, wall, membrane, battens and cladding. Link to comment Share on other sites More sharing options...
