4 Year External Wall Insulation programme

Client: Newport City Homes
Project: 4 Year External Cladding programme.
Value : £4,000,000

SERS have commenced and completed year 1 of a four year partnership to install external wall insulation to thermally improve and upgrade the stock of Wimpey No Fine houses belonging to Newport City Homes. In total 400 properties have received external wall insulation in the Bettws and Ringland area.

This scheme has also gained a 2011 Business Excellence Award by Newport City Council for its contribution to Energy Saving.

Design and Aesthetics

SERS worked closely with Newport City Homes to  choose the desired appearance. SERS attended a number of resident events in order to promote the scheme prior to any work commencing to show a choice of colours and finishes that could be available. In addition individual surveys to all properties took place to ascertain preferred colour choices and design details required per house. Colour choices were then  chosen on a majority rule basis.

The partnership decided to use two system designers WBS (Bettws estate) and SPS Envirowall (Ringland estate). This provided the best solution for value and logistics.

The desired finish included the use of a thin coat silicone render on the ground floor separated by a brick banding with a render dash finish on the upper floor. 50ml phenolic insulation was mechanically fixed to the substrate with some wall tie replacement needed .

The houses were mainly end and mid terrace. Other works included replacing soffits, facias, downpipes and guttering, extending flues and installing new canopies.

Quality of Work

The quality of work has been to a very high standard . At first a pilot scheme was carried out on a small number of homes to ensure all quality standards were jointly agreed and achieved. This was then used as a benchmark for the rest of the project. SERS work against Key Performance targets which are reviewed monthly by the partnership team. All residents are kept informed on a daily basis whilst the work is taking place and on completion a satisfaction survey is conducted.

Technical Difficulty

All work is carried out with residents in situ. SERS work closely with Newport City Homes to ascertain any special requirements prior to work commencing. A communication protocol was developed jointly and strictly adhered to.

Thermal Performance

The properties have been significantly improved in terms of thermal performance with 0.30 u values are being achieved, resulting in less energy required to each property.
