Senior makes window ventilation a breeze M
eeting the individual ventilation requirements of different buildings can be a challenge, which is why leading aluminium fenestration solutions manufacturer Senior Architectural Systems has developed a range of specialist products including a Louvre Guard system and automatic opening ventilation (AOV) aluminium windows. Senior’s Louvre Guard system is a stylish aluminium louvre which is compatible with the inward opening designs of the company’s popular SPW600 and PURe®
windows. It is ideal for high-rise buildings where ventilation
strategies must address the need to reduce the risk of occupants falling from windows. Easy to install, Senior’s Louvre Guard comprises an external adaptor and oval shaped blades which are fixed to the outside of an inward opening window. The system can be fixed through the face of the window or through a bespoke coupling mullion to maintain the thermal barrier. Available either in anodised silver or
bronze, or in any standard RAL colour, Senior’s Louvre Guard system adds an extra design element to give any building a distinctive look. The blades can be positioned horizontally or at any angle up to 45° in either direction, and has been tested to 3 kN for barrier loading at a maximum blade span of 1,000 mm.
Senior can also offer a high performance aluminium window system with automatic opening ventilation (AOV). Based on the same aesthetic design as the manufacturer’s popular SPW600 aluminium window system, Senior’s AOV version is fitted with a smart actuator which allows for quick and automatic ventilation in the event of a fire to

help to remove smoke from the air. The three chamber 75 mm polyamide
window system has been designed to achieve impressive thermal performance and is available in a wide range of colours and can be top, side or bottom hung. For more information on Senior’s extensive

Proctor Air® provides peace of mind for apartment residents during essential reroofing works
A
significant challenge when working on the roof of any existing, occupied building is protecting the people inside
the building without the full roof system in place. Tat challenge is multiplied when the building in question is large and work has to be carried out in sections over a longer period of time. At Hatchemeadow apartments in
Northumberland, a key performance characteristic of Proctor Air that helped to address these challenges was its water holdout. Tat, combined with its vapour and air permeability, offered long-term peace of mind for the building owners, as well as apartment residents. Te roof included an area of solar PV panels,
so the new roofing system had to be capable of providing weathertightness and condensation control in several different circumstances across the single building – all while residents remained in occupancy during the work.
USING PROCTOR AIR AS PART OF A ‘BELT AND BRACES’ SOLUTION James Roy, senior quantity surveyor at Wensley Roofing, describes the replacement roof system as a “belt and braces” approach. “Te specification used Proctor Air over the
raſters, followed by counter battens, tile battens, and a new pantile finish,” he explained. “We even

about leaving the underlay exposed for short periods of time. “Te belt and braces approach has made labour
a challenge on this project,” said James. “But with the Proctor Air membrane in place, we’ve been comfortable leaving it exposed for a couple of days if necessary, knowing that residents in the apartments below are still protected.” Tis reassurance is possible because Proctor
used butyl tape over the nail holes to provide a complete seal against rainwater.” At the time of writing, Wensley Roofing are
about halfway through the reroofing work. “Some of the residents were having to use buckets to catch leaking water,” said James. “Since installing this new system the leaks have now stopped, and there has been some bad weather.”
HOW HAS PROCTOR AIR HELPED THE REROOFING PROCESS? Te attention to detail required to deliver the thorough specification, coupled with the size of the Hatchmeadow apartments roof, has naturally restricted the pace at which the work can be delivered. As a premium roofing membrane, Proctor Air has helped to alleviate any concerns
Air is rated W1 under EN 13859-1, with over 1m Head of Water, and has hydrophobic additive in all three of its layers. Its water resistance meets the guidance of NFRC’s Technical Bulletin 6. Additionally, the membrane can be leſt exposed to UV for up to three months. Proctor Air allows the underlay to be used on
roofs featuring solar PV, as long as a ventilated batten space is provided. Tis is in addition to tightly-jointed slates, tiles and metal sheet, all of which would also normally be considered vapour impermeable. Because the Hatchmeadow apartments
specification featured a counterbatten layer, Proctor Air could be used with confidence across the entire roof, including under the existing area of PV panels.
