Procheck®
A2 membrane delivers speed and
performance on regeneration project O
ccupants of Moda Living’s 722-home build-to-rent scheme at Great Charles Street in Birmingham will soon enjoy the thermal comfort benefi ts of airtight building fabric, thanks to installation of the A. Proctor Group’s Procheck®
A2 membrane.
The accommodation comprises a mix of one, two and three-bedroom apartments, including some penthouses. As of April 2025, work is well under way by Titan Interior Solutions (part of the Horbury Group) to complete the membrane installation as part of the full internal fi t out package on blocks B and C of the project.
Internal airtightness line puts onus on product handling and ease of installation The 16-storey block B and the 5/6-storey block C of Great Charles Street both feature a concrete frame with brickwork fi nish. This is in contrast to the 39-storey block A, which features a facade build-up and is outside the scope of Titan Interior Solutions’ work. The external wall structure of blocks B
and C meant the airtightness line was specifi ed internally. That has required the company to install an air and vapour control layer (AVCL) membrane to the internal face of the walls. Procheck A2 is a vapour and airtight membrane.
EN 13501-1, meaning it is considered limited combustible with no contribution to fi re and can be used in relevant buildings and those over 11 m / 18 m.
Better handling and faster installation make a big difference on a large project like Great Charles Street. With an internal airtightness line, installers had to work around a lot of penetrations, including ducts, pipes and brackets. Thorough checking of work has also played a signifi cant role in the delivered results.
Its composition gives the
membrane a high degree of vapour controlling properties, as well as being airtight, which allows its use as an AVCL and helps contribute to the thermal effi ciency of the building due to its’ refl ective surface. It is also rated A2-s1,d0 when classifi ed to BS
The change in product and the approach to quality control has so far paid dividends. Finished apartments that have been airtightness tested have averaged a result of below 2.0 air changes per hour (ACH) at 50 Pascals pressure. It gives an indication of the performance and thermal comfort that eventual occupants can expect to enjoy.
