Project brief

Nu-Heat were tasked with the design and supply of a bespoke underfloor heating (UFH) system for Coble Quay, an exclusive waterside development in Amble, Northumberland. With stunning views across the marina towards Warkworth Castle, the 25 apartments and retail area make the most of their enviable location at the southern gateway to the Northumberland’s Heritage Coastline.

The UFH had to be low-profile in order to maximise ceiling height, whilst also providing a reduction in airborne and impact noise between floor levels. Fast installation times were also important to meet a tight build schedule.


Project solution

ADPK14 for the upper floor residential and retail spaces

Nu-Heat specified and supplied ADPK14 for all the upper floor apartments and retail space, 2,785m2 in total. This low-profile, high-performance underfloor heating system uses diffuser panels in an acoustic floating floor that is laid over the existing floor deck. ADPK14 significantly reducing airborne and impact noise between apartments and retail spaces. A flexible, dry solution, ADPK14 was also ideal for Coble Quay’s build schedule as there is no drying time and floor finishes could be fitted immediately after installation.

  • Installed directly over the structural floor deck
  • Fully tailored design incorporating low-profile diffuser panels in an acoustic floating floor
  • Fast heat transfer and high performance heat output
  • Can assist in exceeding Part E requirements when correctly installed as part of an acoustic floor cassette
  • Just 48mm total height build up before the final floor finish
