A factory pre-insulated PPR pipe for hot and cold water services. A PPR service pipe sits inside a rigid closed-cell polyurethane foam insulation layer and a high-strength anti-aging outer casing, so the insulation is applied under factory conditions rather than on site. Standard sizes run from DN20 to DN63.
