Looks great

[@neilsmith3768]

Hi great video. I'm also in Sheffield debating whether to do the ufh like yours or use the routed chip boards. are you happy with your decision so far?

[@hewoguys2506]

do u have any vents under the joist also did u put any damp membane anywhere

[@Erindale]

A year on, are you happy with the result still? You only had a shallow screed, would you recommend deeper?

[@boltsandbrass]

Its certainly been a while for an update but we are almost finished and editing some of the old content to share with you all. We're over the moon with the result.

Hi...thanks for posting this....just about to start my underfloor heating project. Can I ask, the Cellecta HiDeck cement board you used, what thickness was it? Was it the 18mm stuff....thanks in advance, Kevin

[@boltsandbrass]

Hi Kevin, yes 18mm thick, really solid and sturdy floor to say the weight and given the suspended nature. Holds the heat very well, we have 9 bi-fold doors and the heating only comes on for very short bursts in that room due to how well it retains the heat.

[@kevinmurphy8712]

Thanks so much for getting back to me so quickly.... Appreciate you confirming the thickness..... I can't wait until I get to the stage when the cement boards are down and I have a floor to stand on. I could tell in your video its a real milestone on a project like this... thanks again.... Kevin

[@richardbatey1894]

Did you calculate the additional loading of the screed? or did you get a structural engineer todo the calculations

[@bapsmcginty4782]

Was thinking that. It’s a lot of weight being effectively supported by how ever many 10-inch screws. I’m sure they had it all worked out.

[@viewer.86]

Decent job, my question is why did you opt for timber joists and not a slab?

[@boltsandbrass]

There was already a significant void under the existing floor and to build it up sufficiently would have cost a small fortune is the simple reason

[@viewer.86]

@@boltsandbrass makes sense,mine is the opposite it's basically floor level 🤦🏻, trying to work out which route to go down.

[@harveysmart2825]

Is it just me or is you tube becoming more difficult to assist with diy support?? Been searching for DIY underfloor heating install video and there all like this video 10mins talking and 5 seconds in the middle showing how the pipe work gos down lol

[@sethshaikh4176]

how thick was the insulation you placed down?

[@boltsandbrass]

100mm insulation sat between the joists

[@garethfraser5211]

Why would you not use the metal reflective plates between the joists then cement board straight on top, then no need for screed?

[@boltsandbrass]

The original joists that were extended and not evenly spaced back in the 70s so it wasn’t the greatest option for us. We did consider it though

[@PercyJackson93]

Supposedly these cement boards aren't great since there's a low contact area

[@gerardoleary9243]

What's the cement board you laid on the top of the screed called ?

[@boltsandbrass]

Hi Gerard, it’s called Cellecta HiDeck, a tongue and groove cement board

[@gerardoleary9243]

​@@boltsandbrass brilliant, can you remember how thick the board is ? Because we are thinking of doing the same, thanks for your quick reply

[@boltsandbrass]

18mm was thickness we used. They’re fairly heavy and smaller sizes than your normal floorboards. The work perfectly to distribute the heat evenly and better than a wooden board.

[@gerardoleary9243]

@@boltsandbrass Yes of course I was thinking of that myself, any ideas where you got them from and the cost please ?

[@weaverbike]

So what was a company going to charge for the whole job

[@boltsandbrass]

Obviously every job is unique, we certainly had a challenging task at hand, we did our research on the materials needed and what was needed to make the floor sufficient to take the UFH pipes and screed. I think in total we spent just over £5k and the quotes we’re around £1k more for 63sqm

[@weaverbike]

@Bolts & Brass thanks for the reply , looking into getting underfloor heating. I don't know at the moment whether to just lay on top and lose 22mm in room height. To be honest, I would just pay the extra for my personal convenience , good KZbin clip.

[@boltsandbrass]

If you have the ceiling height I would overlay! Latting every joist and the notching the pipe runs was very time consuming and will increase labour. Be a lot cheaper if overlayed I would guess.

[@mateeullah9376]

Is that normal cemnt board over the screed or its something else can you please mention the name

[@boltsandbrass]

Yes they are regular cement boards. Cellecta HiDeck is the brand
