energy-efficiency and interior comfort at Wealden District Council With the objective of saving the local taxpayer over £370,000 a year while also maximising efficiency and reducing energy consumption, Wealden District Council has consolidated its administrative facilities into a single property, choosing to expand and renovate its premises in Hailsham. This blockwork and brick-skin building was totally refurbished by the appointed contractor Wilmott Dixon, with the responsibility for building services assigned to the Frankham Consultancy Group.

The refurbished building was designed to benefit from a more energy efficient heating system using passive ventilation and making better use of the building’s fabric to control ambient heat. In order to manage thermal gains, improve interior comfort and reduce the need for energy-hungry climate control, Frankham proposed the installation of a phase change system, exploring the options before specifying DuPont™ Energain® advanced thermal mass panels.
DuPont™ Energain® was chosen for its superior characteristics and also for the quality of the service offered, which included transparent costing, reliable delivery and a helpful calculation model to measure the quantity of product required for optimal savings in the structure:
Based on supplied drawings and using DuPont’s building design software system, simulation graphs were generated by DuPont to demonstrate the performance of the system when installed into the entire second floor level ceilings. After proving the case successfully to all parties, 650m2 of DuPont™ Energain® was ordered in January 2012 and
the installation behind a single layer of plasterboard was completed during February, providing a total heat storage capacity of approximately 91000 Wh (temperature window: 18- 24°C) and thereby achieving up to 5 to 6 degrees passive reduction of interior peak temperatures.
DuPont™ Energain® is an advanced phase change system supplied in lightweight, easy- to-install panels of 1.0m x 1.2m x 5.26mm thickness, which are sealed behind the plasterboard in walls or ceilings using standard tools and working practices. Build time, energy use (both on site and in transport) and weight loadings are considerably reduced using this straightforward solution.
DuPont™ Energain® works by absorbing ambient heat as room temperature rises (at around 22°), storing it until the temperature drops again (at around 18°), and then releasing it back into the room. In
ventilated structures this can make a significant difference to comfort and also to the choice of construction methods and materials. In buildings with air-conditioning DuPont™ Energain® can reduce costs by up to 35% and help to reduce heating bills in the winter by up to 15%

Scottish Gas chooses RoyalCrest Cladding
BISEWI LTD, major insulation installers in Scotland, are working with Scottish Gas on Grant Aided
Insulation to older homes lacking the necessary insulation values and have chosen RoyalCrest Vinyl Cladding as the preferred exterior.
Director Eddie Dawson stated that aestheti- cally and technically he felt it was better than other similar looking products. It is more robust whilst being much lighter which is an important factor. Vinyl Cladding can be installed easily by one operative and has a unique moisture release system which allows for application in any weather, will not crack or stain, does not cover workers in dust when being cut, and requires no joining strips, so no setting out or caulking is required.
It is also one of the most environmentally sound products on the market according to the Vinyl Siding Institute of North America where it is a Premier Building Product.

Throughout the manufacturing process, on the home and even after it has fulfilled its useful life, Vinyl scores well on tough environmental tests. Vinyl Cladding is friendlier to the environment when considering factors such as air pollution caused by production, fossil fuel depletion and global warming impact.
Vinyl requires no staining or painting over its whole life, is fully recyclable and is guaran- teed for FIFTY YEARS.
