Using Celotex XR4000 insulation for a house redevelopment in Bath
|Products Used:||Celotex XR4000|
At the sustainable redevelopment of a 1960s home in Bath, property developers ST8 Ltd ensured every product and material used would provide energy efficiency, quality and long term performance. When selecting insulation for the ground floor and two flat roofs, the company turned to the UK's market leader in PIR insulation, Celotex, helping the new-look Chelsfield House to gain 'SuperHome' status and achieve an outstanding carbon reduction of 76%.
Located in Lansdown, Bath, Chelsfield House was originally built in 1965 and was in a state of disrepair when acquired by ST8. With more than 25 years' experience in redevelopment, the company set about transforming the inefficient property into a warm and inviting 21st century home with the integration of state-of-the-art technology and environmentally friendly practices.
To create a highly energy efficient building envelope and complement the ground floor's underfloor heating and two sedum-topped flat roofs - ST8 required versatile and high performance insulation that would help to deliver significant carbon savings.
Specifically targeted for floor applications, Celotex XR4000 insulation boards were specified by ST8 for their reliability, workability and outstanding thermal performance.
Available in a range of thicknesses from 110mm to 200mm, the thickest PIR insulation on the market, Celotex XR4000 insulation boards are suitable for a range of applications including roof, wall and floor systems. They include low emissivity foil facings giving improved thermal insulation with cavity air spaces.
Celotex XR4000 boards are highly workable, the installation of them is simple. Durable and lightweight, the boards can be easily moved around site without risk of damage, and they can be simply cut-to-fit with hand tools on site.
"We're always looking at ways to make greener, more sustainable homes," commented Nick Sandy, owner of ST8. "We believe that insulation and ventilation is the starting point for every sustainable development so it's crucial to get these elements right. At Chelsfield House, Celotex insulation offered us outstanding versatility whilst meeting our high standards of thermal performance."
Chelsfield House provides an exemplar of sustainable redevelopments and has become one of only 95 SuperHomes in Britain. The specification of Celotex insulation by one of the country's leading green developers emphasises why Celotex is the market leading PIR insulation provider and is the first choice with architects, specifiers and designers.
When using Celotex products, you need to satisfy yourself that use of the product meets all relevant national Building Regulations and guidance as well as local, national and other applicable standards relevant for your construction or application, including requirements in relation to fire and applicable height restrictions. In addition to the product datasheet, please refer to the following product documents:
- BBA certificates - where applicable to the application
- Declarations of Performance
- Health and safety datasheets
Celotex products should not be used in the external walls of buildings over 18 metres in height (England and Wales) or 11 metres in height (Scotland). Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility can be used in buildings of that height.
