Any builders on here...?


Thanks mate, think I'll get it rendered like. Would love to sort the insulation etc. when I replace the kitchen but can't really afford to do it all right now so will need to think of something.

Some great advice on this thread as always!
Do the rendering, let it dry properly inside, and then sort it when you do the kitchen later mate. At least you'll know it's been done correctly.👍
 
Did you choose the insulation boards because they were cheaper, easier or more effective? I'm thinking battens and filling with either loose or the boarded insulation, then plasterboard over the top because I can do that myself. I'm not certain I woudln't make a pig's ear of insulated plasterboard and getting somebody to do it obviously ramps up the cost.

For the vapour barrier - what is the rationale behind having between the battens/insulation and the plasterboard rather than between battens/insulation and exterior wall? I'm not suggesting it's wrong - just trying to get the reasoning sorted in my non-DIY head.

I used celotex or the equivalent because of its insulation values. I only wanted to lose an inch so other insulation types would be pretty poor at that thickness. It's expensive to buy is the downside.
The vapour barrier goes on the warm side so behind the plasterboard. I lapped that up onto the ceiling vapour barrier and taped everything with aluminium foil tape. The utility room has a washer, a dryer and a floor standing boiler so I didn't want warm moisture reaching the cold bricks or the roof timbers. Since I did it though I've removed the plasterboard and added another inch of celotex to the two outside walls. I was changing the units in the room so could rearrange them. Losing the extra inch didn't matter.
if you want a very good forum for help you'll find it on the link below. I've had structural calculations and all kinds of advice from the tradesmen on this forum. It's worth joining and asking there.

Thank you. That is all really useful and I'll certainly be reading the DIY forum.

Having a big brick isn't as good as it sounds.
I think it would be expensive (and probably painful) to change the brick size :)

The insulation on a pir backed board is a lot more efficient than a loose "wool" product though so you could use a thinner system and get the same heat benefit.
Like gypliner and insulated board straight on, depends if losing a couple inches more is an issue mind, it might not be.
Is it just one big wall, no windows or anything?

Not worried about losing the space. It's a galley kitchen, but we can live with the wall coming in a few inches.

There are two double windows but they were re-fitted last year and the bit between the window and the inside of the wall (I don't know what it's called - the bit that is at 90 degrees to the wall) wasn't finished as we had planned to insulate the wall. So we can sort the finishing out ready for the plasterer to skim it all over.

It will be amazing to have a nice kitchen rather than the bomb site I've had for the last 3 years. Just need to work out how I cam going to pay for it now. Finance Committee meeting this weekend!
