Nottingham Dental Practice, Refurbishment

Brief:

The project called for the old render to be removed and replaced with a new external wall insulation system. This would help to improve the thermal performance of the building as a whole, while also refreshing its appearance and offering enhanced protection against the weather.

Design and Specification:

Permarock’s technical team worked with the project design team to agree the following specification for the EWI system:

• Permarock EPS Premium External Wall Insulation: Lightweight insulation boards, mostly of 40 mm thickness, all adhesively bonded and mechanically fixed to the substrate;
• Permarock Silicone^Ultra K Finish (textured render).

The Permarock EPS insulation was supplied in boards measuring 1200 mm x 600 mm. Generally, they were installed to a thickness of 40 mm but other thicknesses were used as necessary to complete the detailed design. The low-lambda boards incorporate microscopic graphite particles, which greatly improve their ability to reflect and absorb radiant heat.

Permarock Silicone^Ultra K Finish is a flexible, vapour-permeable render that is attractive, durable and capable of producing an effective barrier against the weather. It also helps to maintain airtight facades, which helps to improve a building’s capacity to retain heat in cold conditions.  It has a textured finish that resists the accumulation of dirt and organic growth. Consequently, it reduces the need for costly cleaning and maintenance work.
