Hi,
I'm about to start on my loft. (Don't worry, this is not about building regulations!)
I need to attach reflective multisheet insulation (20mm thick wadding type) to the underside of 3"x2" rafters. Then 25mmx30mm timber horizontal at 2 foot spacing on top of this. Then foil backed 12.5mm plasterboard on to that.
The questions is - what do I use as fixings?
I had been advised Staples to fix the insulation to the rafters - do they have to be galvanised? What size?
Then "special screws" through plasterboards, pre drilled battens and insulation? 3 inch? Apparently the insulation will tear up internally and create a right mess if you a) drill through it or b) don't use these "special screws"
My idea:
Can I used a nailgun and nail (what nails to use?) the plasterboard, battens and insulation direct to te rafters? perhaps using adhesive to tempoarilly attach the insulation to yhr rafters and the battens to the plasterboards in the first place?
Does anyone have any experience with this? What nailgun should I buy? Will an electric one (£12.50 on ebay) do the job?
So many questions - and its the christmas project!
