Hello I need to fit a fire door frame between a living area and a garage. I've picked up a frame but cant understand why the fire door frame is 40mm taller than standard frames? I know the wood is slightly thicker but doesn't account for 40mm. Also do you need a intumescent strip at the bottom...

I have an un level timber floor which has had 6mm ply put on top of 18 mm floor boards. The amtico company want to level it with as much as 10mm latex. Will the weight of this be ok as they are 1930 joists 4x2 . I was told to tile you need to reinforce the floor. Surely this thickness is the...

I have layed 100 mm insulation that will be screeded. I will have UFH laid prior to this? Any suggestions on the upstand insulation? I see you can buy rolls of 8mm thickness but have also read it should be 25mm thick? A company that offer a liquid screening service said to lay it on the outside...

No the liquid screed will be next to the timber floor - where I haven extended out and to the side. Cheers

Anyone had liquid screed pumped before? Just need to know the tolerance you can get away with on your timber floor it's sitting next to . Mine is about 8mm out over 3 meters.

Thanks, Pack them up from underneath? With plastic? If I knock the first course off then the liquid screed will just flow through to underneath the floor boards? Was thinking of bedding timber on mortar on top of this bricks? What you think?

Hi, As you can see in the pictures my liquid screed will meet my existing timber floor on 2 sides. The timbers are not level. Is it best to cut/ lift the floor joists possibly replace and get them level?its about 10mm out at various points. They have been lifted as I'm putting underfloor heating...

I had a 203x203x86kg steel fabricated. In the web are 4 holes- they attach another steel at a T join. The absolute idiots drilled them 100mm out of place. I realised after lumping the 500kg weight round the back. The company said they will re-drill the holes on site. I said, what about the...

After carrying out an extension for a few years (mostly self build) I have decided to knock another walk down (major balls up that it wasn't done when the original steels went in I know) At the back of the original part of the house 3 steels were fitted. As I want to knock another wall down I...

Thanks woody. I have spoke to various liquid screeding company's and they all say 50mm is recommended. Thanks

hello, I am about to lay my 100mm of insulation onto my concrete slab and then have roughly 50mm of liquid screed pumped on top (with underfloor heating pipes in the screed) However my concrete is roughly 40mm out in places. Would it be ok to do a semi dry mix of sharp sand and cement to build...

is it ok to have a light switch and a fused spur in a room that has a toilet and basin ( the spur is for a macerator) The switch will be on the oppersite side to the basin/toilet. Thanks

A grundfos sololift2 wc1 macerator. I have 2 options with the outlet pipe; If it's 32 or 22 mm it will run up vertically 2.5 meters- then run through the loft 6/7 meters horizonatally then back down 1 meter and into the stack. If I do use 22mm I could possibly run it down 200mm then a horizontal...

Anyone got much experience with macerators? Initially I was going to use 32mm pipe for the outlet but some people have mentioned that 22 mm works equally as well if not better ? I thought the bigger size would be best?

Hello, I am looking at fitting a combined vanity unit (see pic) Is it possible to incorporate a macerator behind the toilet ? Has anyone else done it with success? Thanks

I wasn't planning on using an underfloor heating wiring centre? I take it they incorporate pcb inside them. Thanks for the recommendation on the 4 wire 240 actuators. The only thing I can't understand now is with the switch live coming out of the ufh actuator - this will go to the boiler but...

But they are only 2 core? So if I get a demand from the room stat to the valve it will open... but how will the boiler receive a switch live?

Do underfloor heating actuators work of 240 volts. I can't understand if I incorporate an under floor heating system to a S plan system how the boiler gets a demand if one of the zones on the under floor heating system is required to heat? I am tempted to just use a zone valve/standard pump/...

I have made a doorway from my existing outside wall to my new bedroom and it goes through a solid 9 inch wall (including my dot and dabbed plasterboard its just over 10 inch) I'd like to have a standard internal door here. All the doors in the house have architrave around so id like this to...
