Our Journey North of the Border

Did the builders have the foresight to take a "Tony Tray" around the joist ends to ensure continuous air tightness at the ground floor / first floor junction?

Hi @ProDave I don't think so, in fact I would almost say they didn't as I didn't see any  such "device", although in fairness I wouldn't know what a "Tony Tray" is, even if it dropped on my foot!! ?

So by way of a lesson for those like me, what is a Tony Tray and what is the purpose of it?

Really coming on now and looking great. £300 is nothing in the great scheme of things and certainly doesn’t compare to the stress it caused you I’m sure. 

 

PS I don’t know what a Tony Tray is either ?

 

 

Not sure you can access ebuild forum anymore, so, a Tony tray is an airtight membrane that extends from the internal airtight layer below the joist, round the outside of the joist ends and back in to join up with the membrane above the floor. Tony used it in a brick and block build but the principle is the same with timber frame. It stops the joist penetrating the airtight membrane which is difficult and numerous to seal up.

Exactly that @newhome

We’ve all been there I’m sure. Crisis averted, lesson learned, ask ask ask! No shame, just support here, in spades, from people who have walked your walk and sometimes been terrified.

Exactly that. My builders suggested it, and they had never heard it called a "Tony Tray"  As with most things attention to detail is important especially at corners.

 

One house I wired 2 years ago now did not do that, and I remember them spending ages taping bits of air tight membrane around every single joist.

House looking great and moving on at a pace. I take it the reason for the battening on the upstairs floor is for the UFH? If so are you using any form of spreader plate? TIA

Hi @Pete Yes the battening is in preparation of the UFH pipes, which were laid today. No spreader plates will be used, just a "biscuit mix" screed covering the entire floor. This "biscuit mix" is an 8:1 sand and dry cement mix - which will then be covered by 22mm eggerboard flooring.

Hi @Redoctober, any pics of that ufh going in upstairs?  The mix will be to the top of the 25mm battens?

Looks good.

 Hi @CC45 - Yes, I will upload the photos over the weekend as the screed mix goes down on Monday.  The screed mix will go to the top of the battens and then the egger boards sit across that and the battens.

@CC45 - additional images uploaded under a new entry - hopefully they will assist.
