Technical purpose This EPD is carried out for the Unilin Insulation Ireland Ltd products: Cavity Therm, Xtroliner and Xtrowall Plus of thicknesses 100mm, 100mm and 110mm each, respectively. The bulk raw materials polyol & MDI are mixed with various catalysts and additives. The insulation products are manufactured in accordance with I.S. EN 13165:2008, Thermal insulation products for buildings, factory made rigid polyisocyanurate foam (PIR) products.
The bulk raw materials polyol & MDI are mixed with various catalysts and additives before being metered onto a moving conveyor. The chemical mix then starts to rise and produce the foam. The foam continues to rise until it
contacts the top layer of facer material as it enters the double-belt laminator, where it is then cured under heat to produce the rigid, thermoset foam board. The board exits the lamination oven and then reaches a cross-cut saw which cuts the board into shorter mother boards. Each mother board then enters a cooling zone before entering a multiblade cutting area which removes side trims and cuts the boards to the required length. There is a minor amount of additional cutting to produce speciality boards such as rebated edges. Finished boards are stored in the warehouse before despatch to customers. Off-cuts from the cutting and trimming are compressed on-site and sent to landfill. |
