Kingspan Kooltherm insulation was chosen for a retrofit of a very narrow house in central London. Slim House, a mid-terrace in Clapham, measures just 2.3 metres across internally.

AIRCRETE PLATE PACKAGE

means minimal leveling of the blocks are needed, further enhancing the time-saving benefits of the Package System.
