Marine plywood perhaps? I just have a sheet of polystyrene over ours as a makeshift lid. Don't forget NOT to insulate below the tanks as the heat from the house should be allowed up to ensure that they don't freeze.MAJJ said:Also, I have two water tanks up there one large round one and another smaller square one. I plan on putting lids on these - any suggestions on what to use?
Be careful what you use the additional space for as without restructuring the attic beams will most likely not be capable of taking the same load as a normal upstairs room floor.plan on partially flooring some of the limited space up there
It won't break up unless somebody meddles with it. Even then it's pretty sturdy.MAJJ said:Lid - I thought of polystrene but being a bit new to this thought it could break up and get into the water system.
i agree with macnas, why remove the old insulation. Just place the new stuff over it. Less work, no expense of dumping the old stuff, extra benefit from the additional thickness of insulation, leaving it there seems a winner all round.macnas said:Why not leave the old insulation where it is and lay the new over it?
.If your attic insulation is currently less than 200 mm, then you should add further layers.
