Hello all, I am doing internal wall insulation on a solid wall house (built about 80 years ago). I have fixed 50mm pir (38mm insulation/12mm plasterboard) directly to the interior of the walls using the 'mushroom head' metal fixings. I fixed the boards directly to the wall to conserve room space and not doing internal walls. I now need to do the same in an upstairs bedroom. I want as thin an insulation board as possible, as the room is only 2600mm wide. The only thin insulation board I've found is stormdry EP (this is a system using adhesive and not readily available). Stormdry EP Board - Energy Performance Board (safeguardeurope.com) Are there any better options? I don't mind the cost, within reason, given the small area. The room needs a new radiator and aside from being 'cool' the room is good as a bedroom as is. My other options are 1. Moving the radiator so it doesn't reduce the 2600mm width (its against the main wall to be insulated). This would mean taking up a good quality floor. 2. Removing the top 10mm of plaster (not much benefit) . I'm not keen to do this, as concerned about 'mess' and disturbing the integrity of the render underneath, although I'm probably just being paranoid. 3. Leaving the wall as is.- The 'flat' ceiling/attic above this particular room has no insulation! If I can insulate better around the dormer window and 'sloping' part of the ceiling/roof alongside the dormer- has anyone done this? Not sure if I can get any access to this sloping roof space. 4. Modern radiator and ceiling insulation only. The room is only 3500mm long by 2600mm wide and has a dormer window so there is a slope over the final third of the 3500mm wall. Thanks

Good to be here thanks. Wondering if it was time and money well spent. It's easy to go down the rabbit hole of adding in extras.

Thanks, I'm enjoying the forums so far. Yes, its 50/50 if I use it or not.

Thank you. Glad to be here.

Hi, I am renovating an old solid walled house in Northern Ireland. I am currently dry lining some of the rooms and landscaping/increasing the size of the garden. The next jobs include upgrading the bathroom wall tiles and levelling/replacing the entrance hall floor. We have architects drawings for a single floor extension of the living area and have yet to decide on the details and size of this extension, although planning permission should be a penalty kick. I hope this forum will help keep me focused on the essentials as I'm already regretting bringing mains wiring to some of the window tops for electric blinds. Thanks
