Insulate Aviary - How to attach?

[Simone2]

hello,

I have a 2.3m x 2.3m metal sheeting aviary.

I am planning to insulate the roof and the side that takes the afternoon sun. (Unfortunately can't change location of aviary).

My idea is to use Bastion 1200 x 600 x 30mm XPS Multi-Use Insulation Foam Board as the insulation on the inside.

Then cover with Bastion 2.5m Clear Polycarbonate Roofing Sheet because i don't want to use plywood boards and I don't want my birds chewing the foam boards.

What can I use to screw these in from the inside?

Will I need to use silicone on the outside around screws to prevent water seepage and rusting the screws?

Any advice welcome, thank you. 

Simone

Hi @Simone2,

I'd advise installing batons inside the roof first which all this can be screwed onto. You could perhaps use three lengths of 70 x 22mm 4.8m Treated Pine Decking cut to span the inside width of the roof. Pre-drill holes in the roof at these locations and screw Buildex Roof Zip C4 HexHead Screws M6 x 25 Windspray Bx100 down through the roof into the battens. The reason for suggesting you do this is to not have un-sealed holes in your roof. The Buildex screws have a  rubber washer that stops water leaking in.

Now that the batons are in place you can simply place polycarbonate over the insulation and use Suntuf Clearfix Roofing Screws - 50 Pack to fix them both into the batons.

Please let me know if you need further information or had questions.
