Have some 10mm and 15 mm pipe in 25mm insulation in my loft. I'd like to fix it to the tops of the joists or the bottom of the rafters. But ALL the pipe clips I can find are either nail-on which can't be used with insulation, or screw-on and not available with a stem long enough for 25mm insulation.
Has anyone solved this, or know of long stand-off clips. I'm aware of the very expensive brass ones, e.g. Toolstation 92644 st 0.5 each.
My next thought is to abandon clips all together, and find some way of using kingspan to insulate a pipe duct. As my next project is my circulating hot water main, I need a very good insulation characteristic to make it viable, without cold-bridging to the joist/rafter.
