Pinroom, raising the floor advice. - flooring type too?

But you should be using Kingspan Thermofloor TF70 which is designed for what you are doing and not Kingspan Thermopitch TP10, which is designed for pitched roofs. Wickes only stocks the TP10 (and TW10) and it is expensive compared to online retailers even after taking account of delivery costs. It all looks the same (probably is, other than the label) and is all similarly priced, but IMO no point using anything other than what has been specifically designed for the job.

 
For TF70 About £20-£30 for each 8ft x 4ft board depending on thickness plus £59 delivery.

PIR Insulation - FWDirect

Our range of PIR insulation features well known brands like Kingspan, as well as more cost effective alternatives such as Xtratherm & Recticel. The selection of products includes various thicknesses of PIR insulation, suitable for the construction of floors, walls & roofs. If you’re not sure...

And if you are able to sacrifice a little bit of the width of the room (i.e. so you can you still get the glass off) , you might want to get some insulation on that single skin external brick wall. 50mm of Kingspan TW50 would make a lot of difference - available from same place.
 
So kingspan is just that. You buy enough and cut it to fit then just fill the room with it?

Kingspan is a brand of insulation board which has become synonymous with the product, like Hoover was for vacuum cleaners. There are other brands too.

And yup, you buy what you need and cut it to size if needed - it can be cut with a kitchen knife or a saw really easily. You'd typically put tape across each join between sheets to ensure a tight fit and stop drafts getting through.
 
Yes, dead easy - earlier in this thread I linked to Kinspan's site (link again here) that tells you exactly how to do it and they have similar guides for walls, roofs etc, so you can make sure you / your builder does it right.

A Guide to Constructing a Floating Floor

A floating floor is a construction where chipboard, gypsum or cement fibre board floor panels are 'floated' across the top of the rigid insulation layer. Read more to find out what insulation thickness is required and how to insulate and install a floating floor.

I did glance at it and thought, yes that's what I want! But didn't fully understand it all😆

So can you stack it? Or it comes in different thickness for different heights?
 
Just do one layer - it comes in different thicknesses.

Remove the existing carpet/ laminate so you are down to concrete. Check that concrete is reasonably flat. Hopefully it will be but if not it may thin layer of latex floor levelling applied.
Then work out difference between floor level in next room and concrete in pinroom, lets say its 70mm. Deduct off 18mm for the chipboard floating floor gives 52mm , so you need 50mm kingspan, the nearest thickness. Floors will then be level with neighbouring room.
 
And if you decide to insulate the walls you could use "Insulated plasterboard" for that so that it is ready for skim / fill and sand.

Insulated Plasterboard - FWDirect

Our range of Thermal Laminate Insulated Plasterboards includes popular brands such as Celotex, as well as our own unbranded equivalents. We also offer both PIR and EPS thermal laminates, allowing for a diverse range of options to match every application and budget. If you’re not sure which...

Brilliant thanks for the advice, it makes a lot more sense.
Hopefully I can get Claire to find the builders for me😆

Try to find somebody that has done proper garage conversions as they will know what they are doing.
Click to expand...
Building regs apply when a garage is attached to a building and state that the garage finished floor level has to be a minimum of 100mm below the occupied living area and if fitted with a link door it has to be fire rated and must be closed.
My thoughts are if you are making a change of use this may have to be approved by a planning and building regs update, plus new insurance assessment.
Sorry to be negative but it may be a good idea to run conversions through the local authorities.

Agreed, all conversions should be run by local authorities / planning as necessary. But many garage conversions fall under permitted development rights so no need for planning but building regs still need to be followed.

In this case it is a bit of a grey area. In previous posts of David's the garage had been "converted" (albeit badly - sorry David) many years ago, so although it is effectively a converted garage the physical change of use already happened years ago. But the conversion wouldn't meet current building regs, so would David be reconverting or just improving on an existing conversion? If it were mine, Ideally, I would want to bring it up to current building regs. Then there will be no argument when you come to sell as to whether it is living space or an upmarket storage space (similar to boarded out loft rooms that don't meet building regs so cannot be classed as a bedroom).
 
When extending my garage the link door had to be a special fire door (looks like normal door though) on a closer chain, also had to use fire proof plaster board on ceiling and fire alarm fitted. Think those where the main regs that had to be met from memory.
 
Russ, that's right - yours is still classed as a garage (and not living space) so needs to be fireproofed so you can park a car in it with a full tank of fuel. Garage conversions that are converted to living spaces fall under different requirements of the building regs.
 
The previous owners or even before them converted it into a room. On the floor plan it was listed as bedroom 4! They had a lodger living in it and then used it for a home cinema.
The utility room at the end of the extension was also built as part of the extension and is linked to the room that was previously a garage by one of those fire doors.

I like to assume when it was converted it was done with permission but it isn't the best job.
 
With Kingspan (or similar) what would happen with the gas pipe? It was lowered to go under the temp step.

Also radiator, is It too low?20220904_145524.jpg20220904_145530.jpg
 
It needs to comply with D19 of the building regulations (see below), but ask a gas registered plumber as he will know what is and isn't allowed.

The Gas Safety (Installation and Use) Regulations 1998

These Regulations re-enact, with amendments, the Gas Safety (Installation and Use) Regulations 1994, as amended by the Gas Safety (Installation and Use)(Amendment) Regulations 1996 and the Gas Safety (Installation and Use)(Amendment)(No 2) Regulations 1996 (“the 1994 Regulations”). The 1994...

So the kingspan will go up to the pipe but leave a gap? Then floor ontop goes over the gap to the wall?
Obviously all the skirting will go and I assume I'll get new skirting, probably something more minimal than what's currently there .

Or the entire length of the pipe is moved down like it is under the step.

There's this strange alcove where the extension attaches to the porch where the gas meter is. The height it comes into the room and way it goes up through ceiling means it'll always be visible in that alcove. But I intend to have shelves in there for the endless trophies and Pinball bits I end up with 😆

A plumber (obviously) moved that pipe down so the new door could be installed. So hopefully they know what they're doing. But it being covered by a floor is the issue that has rules with it? Hopefully we'll find out when we find some builders!

Just call up the plumber who moved the pipe down and ask him whether kingspan/overboarding would comply with building regs in relation to the gas pipe. He should be able to tell you and if allowed what the builder needs to do in order to comply with gas regulations (e.g. plumber may say you need a batten running alongside the gas pipe in order that the floor is adequately supported to give greater protection to the gas pipe etc..

Plumbers are not normally qualified to work on gas installations unless they are registered to do so i.e Corgi Registration. All gas work/changes have to be certified and the same applies with electrical changes.
Here is advice on how to approach a gas alteration.

What if I carry out the works around the gas pipe?​

Building over or compromising the position of a gas pipe has the potential to pose a serious risk to life and property.

  • Gas pipework could leak as a consequence of building works.
  • Escaping gas could enter the fabric of the building including cavities and voids which is very dangerous and could lead to ignition or explosion
  • Any leak in confined spaces or voids may be undetected by smell
If the gas service pipe or meter location are compromised because of the works, at your expense, the gas transporter will need to reposition the meter as close as is practical to the front face of the house, connecting back into the internal pipework. If the alteration works are undertaken at the time of the building works it will save you time, disruption and further cost.

What if building works have already taken place?​

If building works have already taken place and the location of the gas pipe or meter may have been compromised, your gas transporter will need to come out and check to ensure there are no safety issues. Please call the National Gas Emergency Service on 0800 111 999.

I am a retired commercial electrician/fire alarm engineer and have been involved with insurance claims caused by fire, Centre Parks Elveden and Heinz foods Norfolk to name a couple, insurance companies are reluctant to pay out if they can prove negligence or non compliance.
Be Careful!

As David had said that his "plumber" had previously moved the gas pipe down below the door I was assuming that David's "plumber" has all the appropriate gas safe qualifications and registration and hence would be able to advise do the work and certify.

And agree with you that great care is needed and that nobody should be messing around with this stuff.

The ramps may sound like the answer but there's no room at the bottom of the ramp when the room has pins in it. So you'd be tipping the pin into another pin or it would still be on the ramp.

Plus I'd love to address this ugly step which is supposed to be temporary just to get the door functionable for our event earlier in the year

Whether you raise the floor or not, it's not going to give you enough room to get a tombstoned pin past there or shut the door?
 
How often are you moving pins in and out would be the first question i'd ask myself. If it's only a couple of times a year save all the heartache and make yourself a ramp out of wood.
