Kiln Place
Initially a renewal project, this roof refurbishment became a sustainability success story. By undertaking an intensive moisture mapping survey, Bauder helped Camden Council reduce its Scope 3 emissions, with measurable carbon savings of over 26 tCO2e.
Synopsis
Kiln Place is a London Borough of Camden mixed tenure (social & leaseholder) residential block in the heart of Gospel Oak.
The building was due capital works, including a roof replacement, as some residential units were experiencing leaks.
Bauder undertook a moisture mapping survey to understand the overall condition of the roof and underlying insulation, resulting in 90% of the existing insulation being retained (whilst complying with Approved Document L), significantly reducing material requirements, waste from the site, project timescales and disruption to residents.
Completed in October 2023, Bauder’s involvement in the project helped Camden Council reduce its Scope 3 emissions through significant carbon savings in excess of 26tCO2e.
Additionally, since the vast majority of the original insulation was retained, the client saved over £100,000 from the original budget as well as benefitting from a shorter project completion time.

Specification and implications for Scope 3 reporting
Our long-established Bauder Total Roof System (BTRS) was selected for the Kiln Place project. A bitumen membrane waterproofing system suitable for both new build and refurbishment applications, BTRS is a well trusted system to replace the areas of the existing roof that have failed. Replacing wet insulation with a new Bauder FA-TE insulation layer provides thermal reliability to help make a building more energy-efficient, one of the Kiln Place project’s main objectives.
To ascertain the exact condition of the current waterproofing system and underlying insulation, Bauder conducted a moisture mapping survey.
Many roof refurbishment projects involve replacing the entire existing roof, or risk overlaying wet and defective insulation.
During the Kiln Place project, however, Bauder was able to carry out forensic analysis of the existing roof for saturation using a Troxler density gauge. By creating a grid map of the roof surface (Fig. 1 below) and taking a reading at each intersection, areas of the roof with trapped moisture were accurately identified, meaning over 90% of the roof’s insulation could be retained.

showing that 90% of the existing roof could be retained.
In the case of Kiln Place, Camden Council achieved significant Scope 3 emissions savings through applying waste hierarchy principals to the scheme.
Through its moisture mapping survey, Bauder Area Manager, Tom Pugh, and his team discovered the vast majority of the insulation that had been programmed for replacement was dry, sound and did not need replacing.
As a result, embodied carbon contained in existing waterproofing and insulation components could be retained, and less roofing material became landfill waste.
Tom Raftery, Head of Sustainability From a material perspective, approximately 67 metric tonnes of roofing material and insulation was prevented from being sent to landfill, which equates to over 6.4 tCO2e emissions savings. When the embodied carbon of the insulation material not required is also factored in, this total rises to approximately 26 tCO2e saved.
These figures are based on the UK Government greenhouse gas conversion factors 2023 and Bauder product EPDs.
