Protect Membranes is supplier of choice for flagship modular development

A variety of wall construction membranes, roofing underlays and accessories from Protect Membranes has been used by modular construction specialists Totally Modular as part of an innovative pilot scheme, built offsite on behalf of social housing provider Citizen in partnership with Coventry City Council.

Built in compliance with BOPAS, CML and LA Building Control requirements, the scheme involved the manufacture of a two-bedroom and a three-bedroom two-storey dwelling in light gauge steel frame, built in controlled factory conditions in Totally Modular’s premises in Birmingham. Using this volumetric modular approach, a series of four fully furnished modules were created, delivered to former disused land in Willenhall and craned into place before being connected together onsite.  Taking just twenty weeks from build to delivery, time on site was reduced significantly in comparison to traditional housebuilding construction.  With offsite construction seen as an ideal way to combat the national housing crisis and deliver a quality, precision product, the pilot was deemed to be successful with the potential for roll out across Citizen’s housing stock where suitable land is available.

A number of Protect products were supplied and installed in both dwellings to help ensure the management of moisture within the structures, ensuring condensation control and strict airtightness levels were met to help meet a minimum levels of 4.00m³/h.m.² or lower. This included Protect BarriAir, an internal airtightness and vapour control layer to contribute to energy efficiency and Protect Zytec, a roofing underlay offering strong wind uplift resistance and good vapour permeability.  The roof structure also included Protect RediRoll, a universal dry fixed ventilated ridge and hip system, to deliver 5,000mm2/m of ventilation as well as the Protect Eaves Skirt and dry verge system.  

Mick Pettitt, Director at Totally Modular commented, “Protect’s comprehensive package of solutions was the perfect fit for this project to help us meet the detailed specification, using materials that we know are tried and trusted.  In particular, the use of BarriAir helped to achieve strict airtightness and vapour control, contributing to an outstanding energy efficiency rating for both properties that exceeded Building Regulation requirements. The dwellings achieved a 97 and 98 EPC ‘A’ rating, which compares very well to the average rating of band ‘D’ for properties built in England and Wales.   Protect understood our needs and provided detailed technical support along the way, whilst ensuring our products were delivered on time to meet our busy schedule.”

The modular homes took just twenty weeks from build to delivery

 

Richard Whittaker, Director of Development at Citizen, said: “The products supplied by Protect were ideal for the modular homes and helped them achieve a high energy rating. There are so many benefits to modular housing which include reduced disruption at site, high thermal efficiency and quick completion. We’re looking forward to seeing the use of modular homes increase in future.”  

Protect’s range of wall, ceiling and floor construction membranes together with its roofing underlays and accessories provides a comprehensive solution to the modular build sector, helping to ensure the whole building envelope and internal structure can be controlled in terms of moisture management, condensation control and thermal resistance.
