Question?

[junglejim]

I’m looking at this detail in the drawings and noticed the ‘site fitted batten’ I can’t see this but also wonder if it’s necessary as looks horizontal which would surely block the service cavity created by the vertical battens. Given it’s in the eaves I may not need the service cavity. What’s not shown in the drawing is the ybs super quilt under the vertical battens. 
I’m probably missing something obvious 🙄

 Sorry I haven’t got any actual photos as not on site at the moment.

Forgive me if I’m being more thick than usual, but is that a cross section detail of the joist/downstairs panels/ upstairs panel junction?

It is normal to have a top and bottom bar to a service void.  Drill or leave a notch where you know services will pass thtough

Thanks that’s helpful…. Another job the TF sub contractor was supposed to have done but didn’t 🙄

Shouldn't the VCL finish behind the battens? If they're service battens, or is there additional insulation going in between?

Yes good point… I was planning on lapping up under the ybs superquilt and taping together so would need to do that before adding horizontal batten presumably.

Is that your main insulation?

[Nickfromwales]

Effective Insulation to Save on Energy Bills

YBS SuperQuilt Trade is a high-performing multifoil home insulation. It has a built-in vapour control layer when fully taped and sealed using ThermaSeal Foil Joining Tape. It’s been specifically designed with the tradesperson in mind due to its flexibility, high quality, and ease of installation.

SuperQuilt Trade ensures your home retains more heat during the winter and maintains a cooler temperature during the summer, creating an ambient temperature all year round. It can be used on walls, floors, lofts, ceilings, roofs, conservatories, and many more!

SuperQuilt Trade’s R-Value is up to 2.84 m²K/W which is the equivalent of 125mm of Mineral Wool. It’s made from 19 layers of thermally efficient layers. It is 40mm thick however compresses down to only 10mm during installation, saving on cost, space, and installation time compared to Kingspan and Celotex.

YBS SuperQuilt Trade contains no floating or harmful fibres. It requires no PPE such as masks or goggles to install, unlike traditional mineral wool.

 

People who have been wasting time fitting 125mm of mineral wool will be devastated that they've wasted all that thickness of wall and time / money...........or they won't.

Jeez, about 15 years ago i used the 30 layer stuff in a loft conversion. At the time nobody had said that it was snake oil. It was a bit of a faff to fit, and tape etc. Now, to be honest, the room created, never got cold, never over heated, and the radiator was never turned on.  I dunno, is it really that bad ?

Doesn’t read well when they knock the competition, by name/type so much.

I will add that before i added a batten for services, and plasterboard, it was like being inside a space module, being blasted to the moon. Beam me up Scottie.

What if you fitted the 150mm of rockwool and it was way better?

[Big Jimbo]

Well i ain't gonna know that @Nickfromwales cause i didnt do that.

 

[Big Jimbo]

I can't go back and test it, cause i sold the gaff.

 Probably a fictitious house that never actually existed, and you posting from a padded cell (like me).
