Inner Park Road is a three story timber framed construction of eight luxury apartments above commercial premises, in Wimbledon, London, by LR Lima Construction Ltd. Each apartment has been built to a high specification, offering an open kitchen/living area and a minimum of two bedrooms, a bathroom and ensuite.
The project requirement
As an exclusive development of apartments above commercial space, Inner Park Road required an underfloor heating solution that met Part E acoustic compliance (resistance to sound) and could also simply integrate with their floor cassette, whilst still giving high heat outputs.
Nu-Heat was asked to provide an UFH system with noise reduction properties to achieve a minimum of 5dB above Part E.
The Nu-Heat solution
Nu-Heat’s Commercial team worked with LR Lima to develop a bespoke acoustic underfloor heating solution, exceeding the initial project requirement.
“For Inner Park Road, we specified an acoustic screed floor construction for the first floor, separating the commercial and domestic space, and ADPK14, a 48mm slim profile acoustic UFH solution that offers a high heat output of up to 112W/m2, for the remainder of the building.
The low height build-up of ADPK14 trimmed the floor cassette depth by 49 mm over the previously specified timber batten solution, saving valuable floor to ceiling height. The acoustic performance of the solution made it ideal for the project with the build site test showing an 8dB airbourne and 15dB impact improvement on Part E.
The apartments use our network ready controls that enable the end user to operate their UFH through their smartphone or tablet via an app.”

Products
ADPK14 – floating
This dry, slim profile acoustic solution using Knauf brio gypsum fibre board was the specified solution for Inner Park Road.
- An acoustic floor cassette to exceed Part E requirements
- Low floor build-up of 48mm plus floor finish
- High thermal conductivity
- Compositional Mass of floor produces a high quality solid floor finish
- Simple dry application, enhancing site continuity
ADPK14 heat output
| Water temp | R = 0.05 (tile) | R = 0.1 (timber) | R = 0.15 (carpet) |
| 40°C flow (35° average) | 59.62 W/m2 | 56.66 W/m2 | 53.70 W/m2 |
| 50°C flow (45° average) | 99.37 W/m2 | 94.44 W/m2 | 89.51 W/m2 |
ASC14 – screed
On the first floor ASC14, an acoustic screed UFH solution, was used.
- An acoustic floor cassette to meet Part E requirements
- Robust detail
- High thermal conductivity
- Compositional Mass of floor produces a high quality floor finish
- Simple, quick application
ASC14 heat output
| Water temp | R = 0.05 (tile) | R = 0.1 (timber) | R = 0.15 (carpet) |
| 45°C flow (40° average) | 66 W/m2 | 59 W/m2 | 44 W/m2 |
| 55°C flow (50° average) | 99 W/m2 | 88 W/m2 | 66 W/m2 |
