G’day!
In Australia, a growing construction technique for caravans is to use a composite panel comprising Filon or similar with xps foam core and strategic hard points for mounting. Benefits are strength, light weight and speed of construction. My son and I have built three teardrops/squaredrops, the first two were the usual heavy ply with either fiberglass or filon outer. Water penetration into the walls was problematic despite much care being taken during construction.The third was entirely frp panels and much improved in weight and waterproofing. My son has now launched into his next teardrop using a diy sandwich panel with ACP outer skin, xps foam core and 3mm inner ply and I am impressed to say the least. Using the right hightech glues the waterproofing is exceptional and aluminium trim simply glues on with adequate pre bending and tape. It is easy to insert wood hard point reinforcing during the gluing up phase for any mounting of awnings, or roof racks etc.
has anyone here used this technique?
