An insulation material comprising an insulation material substrate with a substrate surface, the insulation material further having a plurality of protrusions affixed to or integrated into substrate surface, each protrusion having an abutting surface distal to a protrusion base and a protrusion body connecting the abutting surface and the protrusion base, and each protrusion having an abutting surface height of at least 2 mm, wherein the abutting surface height is the shortest distance between the plane of the abutting surface and the plane of the protrusion base.

Apparatus for producing bent multi-sided pultruded fibre reinforced plastic reinforcement bar for concrete (commonly known as FRP rebar) comprises multiple resin wetting stages to simultaneously resin impregnate multiple bundles of fibreglass rovings continuously drawn through the resin wetting stages, multiple spiral winding stages arranged to spiral wind warps around the multiple wet rovings, and multiple rotating multi-sided former frames for continuously winding thereon the multiple wet rovings and holding the multiple rovings while curing.
