- Welcome back!
As a few of you have been asking about how we insulate the concrete floor...here it is!!
We hope you enjoy the video and find it helpful. Please let us know if you have any questions.
Thanks for watching!
Great video again!! Good to see James presenting too
Thank you!
Hi, great video well explained. Having pir boards in top of the concrete slab; would that be suitable for having gym equipment on top. Thinking treadmill, squat rack, plates bench etc concentrated in a particular area.
It’s absolutely fine. Put 22mm t&g moisture resistant boards down if you want to be super safe but we’ve used 18mm with no issues 👍
hi was this a flat roof with no pitch..was hard to see ..just interested....nice build looks very sturdy..thanks.
Yes it was 70mm drop
Another great video… here’s a question… how tall are you? Trying to gauge the ceiling height 😂
Good question! I’m 6ft 👍
Great video and thank you. I am planning on building my own and just wanted to ask why your method installs the floor later, as most I see do the floor first ?
As we do a concrete base this is really the only feasible way. If we were doing timber base then yes floor would go down first then walls ontop.
Enjoying the build videos as i am planning on building my own and i wanted to ask does it make a difference where you buy the materials from ? have you got a preferred suppliers?
Whoever is cheapest and delivers the materials without damaging them!! Usually Jewsons 👍
What is the plan for outside.
Hi, id really like your input on my build please.
My floor is a wooden base supported by concrete pillars throughout.
I used 100 mill insulation between the joists but it doesn't have a foil back, im about to put 18 mil OSB sheets over the insulated frame.
My question is should i use foil vapor barrier or breathable membrane before i lay the OSB on top of my insulated base.
Thanks, im a bit lost on it.
Breathable membrane would probably be best. facing outwards so any moisture inside can escape but will not let any moisture in coming up from the floor 👍
@Create Garden Rooms Ltd Ahh that's a great help, Really appreciate that Mate, thanks for getting back so soon. I'll get that tomorrow now. Thanks again.
With the plaster now touching the floorboards do you need to leave a gap to stop any potential damp creeping up?
There will be no damp on the floorboards!! If there was then there’s big problems.
There’s always a gap left between the floorboards and walls, it’s so the floor can expand and contract 👍
What blade is it and where from
Does chip board expand with the seasons?
I would of thought it’s marginal. It makes sense to leave a small gap around the whole perimeter to allow for this.
I notice the glass on the door and window is covered in condensation. Is this going to be an issue. I pulled a damaged panel off my shed wall and under the insulation the wood was covered in moisture and mold. I've put in more facia vents.
The plaster is drying! Going to be a lot of condensation until it's dry
what blade are you using in the jigsaw for the PIR? Thanks
It’s a Bosch insulation blade from Amazon 👍
@@creategardenrooms thank you
I have a question - do you think, the same kind of insulation on the floor can be in gardenhouse above cellar?
I mean what you use -
1. plastic separate foil
2. PIR insulation
3. OSB
I allready build one cellar and next step is to build some gardenhouse, dimensions are prox. the same.
Thanks
Yes I think so!
Do you have any ventilation
Big window on there for ventilation, I'd imagine it has a trickle vent aswel.
Ventilation for what Elliot? Cheers
Do you not need to Foil Tape the joints?
Can do but the sheets are pushed tight together so I’m not entirely sure what the point would be 👍 Not sure a thin 1mm piece of tape is going to do much!
I think it just 100% ensures no cold spots
Hi, what blade do you use for cutting the pir .
Cheers Donald
If you were building your own garden room would you opt for a concrete base like this one or a timber floor?
Always concrete base my friend 😁 they don’t build houses on timber 😉
@@creategardenroomswhat are the pros / cons of concrete base vs another well known garden room company on TH-cam that uses timber floor. Is internal height affected?
@@hewhorockethyou don't want mouses building a colony under a timber floor. :)
