Regis Gate, Kent
In Sittingbourne, North Kent, Rydon has replaced an ageing care home with a new £6 million state-of-the-art building for social housing provider AmicusHorizon. The project required a high performance insulation to be installed in the partial fill cavity walls to ensure a thermally efficient envelope.

Achieving BREEAM very good with CW4000 insulation in social housing buildings
IMPORTANT: We have recently identified a compliance issue relating to our calculation and testing of the lambda value of products in our 4000 and 5000 range and the Crown-Bond and Crown-Fix products within Crown Flat Roofing range. Please note that CW4000 manufactured after 15 December 2017 will be marketed from January as Celotex CW3000 with a declared lambda value of 0.023 W/mK.

In Sittingbourne, North Kent, Rydon has replaced an ageing care home with a new £6 million state-of-the-art building for social housing provider AmicusHorizon. Built over three storeys and comprising a total of 51 high specification apartments, ‘Regis Gate’ is a mixture of affordable home ownership and rent for people who need dedicated older persons’ housing. The design of Regis Gate had to achieve a BREEAM rating of ‘Very Good’ for community areas and a Level 4 rating under The Code for Sustainable Home (CfSH) for the residential units.
Externally, the Regis Gate development features a brick construction with balcony areas on the upper floors. The project required a high performance insulation to be installed in the partial fill cavity walls to ensure a thermally efficient envelope. As a design and build contract, Rydon worked closely with its team of design consultants to value engineer the project in order to achieve the project objectives.
To meet the thermal performance requirements within the cavity wall’s spatial restrictions, specialist contractor Landmark Brickwork installed 2,500m2 of Celotex CW4000. Specifically designed for partial fill cavity wall applications, it was supplied at a thickness of 90mm to meet the standards of thermal efficiency required with minimal effect on the internal floor space.
Made from PIR with low emissivity foil facers for enhanced thermal performance within cavity air spaces, the product offers an excellent lambda of 0.022 W/mK and can achieve up to 100% more thermal efficiency than many mineral fibre products – delivering better U-values without compromising on internal living space.
As a result of the partial fill cavity wall specification – Rydon Construction was able to meet its energy efficiency requirements with a high performance insulation solution.
With its high quality and sustainable solutions, Celotex helped the project to meet the target U-value of 0.2 and 0.28 W/m2K for its external walls to keep it on target for CfSH Level 4. The specification of 90mm Celotex CW4000 enabled an efficient installation in a restricted space that has also contributed to the building achieving a BREEAM rating of ‘Very Good’.
