The Building Envelope

As concerns about inadequate roof fire barrier installation grow, Marley’s Roof Defence can help housing association specifiers deliver guaranteed protection against the spread of hidden roof fires.

Building Regulations require that new homes are built with fire protection measures to delay the spread of fire and allow crucial time to escape. So, when a roof is compartmentalised between adjoining homes, fire barriers are seen as an integral safety feature, to prevent the spread of flames and smoke in case of a fire.

A combination of wall and roofing membranes from Glidevale Protect has been specified and installed on a new build social housing scheme built by Countryside Properties PLC, working in partnership with the affordable housing provider, emh group.
The Protect TF200® breather membrane, branded as Countryside Properties, has been used on all external walls to offer protection during construction and to allow water vapour to escape into the external wall cavity, minimising the risk of condensation within the structure.  All pitched roofs across the site feature Protect VP300, the LR vapour permeable underlay, providing a secondary line of defence to the roof covering, ensuring water tightness and suitable wind uplift resistance to meet the wind zone requirements of the site’s location.

Noise pollution can have a significant impact on resident quality of life, so should housing associations and commercial contractors be doing more? HA Magazine reports...

Noise pollution was recently listed as second only to air pollution by the UK’s Chief Medical Officer for its negative impact on public health. Studies show that exposure to unwanted noise can contribute to sleep disturbance, hypertension and even diabetes and heart disease.

So, given this, should housing associations and their supply partners be re-thinking their approach to move beyond requirements in Approved Document E to deliver a step-change in acoustic performance - particularly in future developments?

As part of a wide scale refurbishment project from Enfield Council, Langley Structures Ltd delivered a series of Flat to Pitched (FTP) roof conversions across multiple residential premises in New Southgate. This project recently won RCI’s Pitched Roofing Awards for ‘best use of a flat to pitch system’.

The project saw the conversion applied to seven buildings located on Bowes Road, Cross Road and Massey Close in Enfield, as part of the larger ‘New Southgate’ refurbishment being carried out in the area. Approved in 2010, the New Southgate regeneration project provides quality homes, local shops and community services across the neighbourhood.

Langley Structures worked alongside Playle & Partners LLP’s, who provided lead architectural services as well as project management, contract administration, quantity surveying and principle designer roles. ENGIE, Langley Structures’ Approved Contractor, delivered the regeneration solution.

Although high efficiency cam action door closers enable low operating forces within and below those demanded within BS8300, some users find any resistance on a fire door either very hard or impossible to manage.

Where such instances arise, the use of a free swing door closer is highly advised. A free swing door closer, when active, enables to door to move freely without resistance being experienced by the user; thus, it enables the door to perform as any standard internal door within a domestic dwelling. In addition to no resistance from the closer, the door can be left in any position desired by the user - fully open, slightly ajar or fully closed. On activation of the fire alarm or in the event of a power failure, the door will close from whatever position it has been left in, ensuring the fire door will perform as required in the event of a fire. Whilst the alarm is active or while power is out, the free swing closer will perform as a ‘normal’ door closer, so if opened it will automatically close again. Once the alarm has been reset or power restored, the free swing will become active once again.

A cladding fire detection system that could offer a lifeline to thousands affected by the UK’s cladding crisis is undergoing a critical period of testing with one of the UK’s leading testing bodies, the Fire Protection Association.

Intelliclad, created by Darron Brough and Mohammed Zulfiquar, believe that their sensor, which would be retrofitted to integrate into the cladding system of high-risk buildings, can provide a smarter, faster and more cost efficient method of monitoring fire safety when compared to the controversial Waking Watch.

Social housing is in the spotlight with new regulations and standards set to significantly increase the accountability of landlords when it comes to the condition and performance of the properties, they have responsibility for.  Here Stuart Nicholson, roof systems director at Marley, discusses how whole roof systems could be one way to reduce their supply chain risk and improve roof specification effectiveness.

Several initiatives, including the recent publication of the Government’s Social Housing White Paper and the Building Safety Bill are precursors to a general tightening of the rules, regulations and standards associated with building construction and condition.

In particular, the Social Housing White Paper is set to place increased scrutiny on the safety and quality of social housing and ultimately make social housing landlords far more accountable for their properties in the eyes of the law.
