Procheck A2, the high-performance fire-resistant vapour control layer system from the A.
Proctor Group has been selected as part of a £6bn regeneration project that will create
over 10,000 homes in Enfield, London, over the next 20 years.
Leading regeneration specialist Vistry Partnerships has been appointed for the first phase of the Meridian Water scheme working in partnership with Enfield Council. Meridian One will see the development of 1,000 new homes with a mixed tenure of private sale, private rent (PRS) and 50% affordable housing spanning 13 blocks ranging in height from four to twelve storeys. In addition, the scheme incorporates 2,235m2 of employment space and over 2 hectares of green, parkland and open space.
Sam Bennett, Commercial Director at SCL LONDON, a Structural Framing Systems and Drylining specialist, commented.“Procheck A2 was selected because it has a Class A2 performance and excellent vapour-controlling properties. In addition, the membrane comes with a high vapour resistance and is airtight, allowing its use as an AVCL.This means that Procheck A2 provides high levels of airtightness which ensures the thermal efficiency of the building.”
“Procheck A2 has an A2-s1,d0 fire classification to BS EN 13501-1, is considered limited combustibility and minimal contribution to fire, and therefore, conforms with the requirements for high rise construction (18m).” The superior performance of Procheck A2 from the A. Proctor Group is the perfect solution, delivering significant benefits to the combination of in-factory manufacture and on- site housing construction.
Procheck A2 comprises a unique design consisting of a glass fibre backing with a pure aluminium foil and clear lacquer coating. It is this clear surface which provides Procheck A2 with the added benefit of a low emissivity surface, which, when used with a service cavity, can enhance the overall thermal performance of the building fabric, as well as ensure a high fire protection performance, with an A2-s1,d0 fire classification. Procheck A2 is designed to protect the building fabric from the potential risks of condensation whilst providing the added benefit of serving as an effective airtight barrier.
Sam Bennett added,“the technical team at the A. Proctor Group supported us throughout and provided comprehensive installation guides giving vital information for both operatives and clients and helping with sign-off at specific hold points throughout the project.” Based on years of investigation, research and development, the A. Proctor Group can offer a superior range of technically advanced membranes to address the safe design of fire solutions in building construction.The installation of Procheck A2 will ensure a high level of protection throughout the building’s lifespan.

For any building to have an energy efficient, healthy, moisture free building envelope there is a clear need to manage the balance of Heat, Air and Moisture movement (HAMM) throughout the building’s life cycle from design, construction, completion and use.
