“Part L has settled down without causing the industry any real problems,” says John Pilkington, marketing manager with mineral wool insulation manufacturer KnaufAlcopor. John Garbutt, marketing manager of polyurethane insulation manufacturer Kingspan, claims the new regulations have increased its share of the market. “We’ve been seeing a lot of people moving to polyurethanes in the past six months, but there appears to be no single solution in meeting the new regulations. Some housebuilders are going for framing, some are going for a trade-off and some are going to thicker insulation.”
European regulations will require the phasing out of the use of ozone-depleting chemicals in foam manufacture over the next two years, but Kingspan has already made the shift. “We have effectively future-proofed our products,” says Garbutt.
