Kingspan Styrozone H 500 R and N 700 R are high performance rigid extruded polystyrene insulants of typical density 35 and 45 kg/m3 respectively, with a smooth, dense skin on both faces.

The packaging of Kingspan Styrozone should not be considered adequate for long term outside protection. Kingspan Styrozone should be stored flat in a ventilated area and protected generally from accidental damage, contact with volatile solvents, flames and extended exposure to UV and sunlight. If it is stored outside for more than a few weeks, it must be covered with a pale pigmented plastic sheet. Kingspan Styrozone should not be left in the sun covered by either a transparent or a dark plastic sheet, since in both cases, board temperatures can build up to a level hot enough to appreciably alter their dimensions or warp them.

Kingspan Styrozone H 500 R and N 700 R are available in the following standard sizes:
