Modular & Offsite Solutions Experts in membrane systems The A. Proctor Group has, for 50 years, been serving the construction industry with an extensive portfolio of technically advanced thermal, acoustic and membrane products. A trusted brand with architects, developers and contractors, the range includes the industry’s highest performing solutions such as Roofshield, the high quality, unique air and vapour permeable pitched roof underlay, and Wraptite, an external air barrier solving the challenge of reliably achieving airtightness in buildings. • Design for Manufacture & Assembly DfMA) •...

Design for Manufacture and Assembly (DfMA) Design for Manufacture and Assembly (DfMA) is a design approach which combines the best of two key methodologies, Design for Manufacture and Design for Assembly. The application of DfMA is ideally suited towards offsite modular construction, with its focus on ease and efficiency of both manufacture and assembly. The A. Proctor Group Ltd has been providing solutions to the construction industry for over 50 years, including an extensive range of superior high-performance vapour permeable membranes, vapour control layers and products suitable for...

Vapour and air movement in a wall structure Heat, Air & Moisture Management (HAMM) in offsite building manufacture Based upon over 50 years of providing solutions and products for the construction sector we understand that a totally holistic approach is required to building design. This is equally essential in the design, manufacture, assembly and construction of offsite modular buildings. In doing so, we consider six core aspects in the process: Occupants Heat Air Moisture For any building to be an energy efficient, healthy, moisture free building envelope there is a clear need to manage...

Standards & Building Regulations With the increased spotlight and focus on building regulations and the suitability of materials specified for use within building construction, the correct selection and application of materials are at their most critical. The key guidance on meeting the requirements of Building Regulations for England, Ireland and Wales, and Building Standards (Scotland) relating to airtightness, energy efficiency, moisture and condensation control as well as fire safety are outlined within the Approved Documents and Technical Standards below. For specific advice on any of...

Standards & Building Regulations Amendment to Approved Document B: November 2018 Guidance on how external walls can meet the Building Regulations requirement for resisting fire spread is set out in Approved Document B. Following the Independent Review of Building Regulations and Fire Safety, and subsequent Interim Report by Dame Judith Hackitt, the Government has introduced an amendment to the Approved Document B: Fire safety, which has a significant impact on the design and construction of buildings above 18 metres. Published in November 2018, the new regulations came into force on 21...

Modelling & Analysis Energy Performance Calculating the heat flows and energy performance can be achieved by using a variety of modelling tools such as U value, SAP and SBEM calculation to more sophisticated BIM models. These models can account for insulation levels, complex life cycle assessments, and allow for optimisation of the building’s design. Condensation Risk Key guidance on assessment methods in relation to the risk of condensation in buildings is given within BS EN ISO 13788:2012. Traditionally, methods of assessment have been based on the Glaser method – a standard static...

External vs Internal Air & Vapour Control The two main ways to achieve airtightness and manage vapour control in the building envelope are internally or externally, or in other terms, “inside of the services zone’ or ‘outside of the services zone’. The use of an effective external air barrier can offer the following benefits: • External air barrier vs internal VCL - An external barrier such as Wraptite can lead to the removal of the VCL - Achieving airtightness and moisture control, whilst reducing the level of insulation thickness required, gaining more space. • External line vs internal...

Protection from Factory to Site One of the challenges facing manufacturers and developers using modular and offsite construction methods is how to ensure that the performance of any factory fitted membrane is not compromised during transportation from factory to site. The exposure to the elements of the UK climate experienced during transportation to site can in some cases adversely affect the quality of the membrane, resulting in damage due to wind, rain, and more. The Wraptite air barrier system offers a safer and simplified membrane system and provides a fully selfadhered vapour...

Product Selector Thermal Insulation Condensation Control • Wraptite The Wraptite membrane has been developed to provide a simple and robust solution to the challenges of reducing air leakage. • Wraptite Liquid Flashing • Wraptite Corners • Wraptite Tape • Procheck Adapt Thermal Insulation Spacetherm’s remarkable performance is achieved through the use of flexible aerogel blankets. Condensation Control Our technical services include condensation risk assessments for individual projects to confirm suitability of our membrane systems.

Air Permeability & Airtightness Air movement is important in the building envelope, both infiltration and exfiltration. We need to control interior conditioned air escaping (whether heated or cooled) and exterior air infiltrating as it puts more pressure on heating or cooling mechanisms internally. Airtight membranes are an obvious choice in this area whether vapour open/closed or variable. PRODUCT SOLUTION PROVIDERS
