Chicken sheds, Piggeries, Wine storage sheds, Workshops and similar of all sizes and construction can be easily insulated with Polyurethane foam with little or no disruption to work. The foam can be applied in one of two methods. Either internally to the underside of roof and internal surface of walls (corrugated or any other sheet profile). This method requires suitable internal access to the area to be sprayed. In most instances, the foam will not require a coating but this can be done for aesthetics if required. Alternatively, the foam can be spray applied to the upper surface of the roof.  Sheet profile and then coated with a suitable acrylic membrane for long term weather protection.
