Kingspan Insulation is pleased to announce that Kingspan GreenGuard GG300 boards now achieve a lower declared lambda value (thermal conductivity) of 0.033 W/mK (0.035 W/mK design thermal conductivity for inverted roof applications).
ROCKWOOL has launched NyRock technology, an evolution in stone wool composition that delivers the lowest lambda stone wool insulation available in the UK.
New from HUECK UK is the Lambda SA I, an innovative window solution that achieves sound insulation figures of up to 31 decibels, even in the ventilated position.
