Wraptite® external air barrier helps to deliver performance and quality in new city quarter development from the start
W
raptite®, the vapour permeable external air barrier from A. Proctor Group, is part of the high-performance
residential building specifi cation in the new Dublin city quarter, Glass Bottle. Connecting Dublin to its bay at the base of
the Poolbeg Peninsula, the development is also linking the communities of Irishtown, Ringsend and Sandymount. The creation of Glass Bottle is transforming some 15 hectares of a former glass bottle-making site that was once home to one of the most modern factories in Europe. Building an entirely new city quarter, that
is also intended to be a city-within-a-city, is expected to take around a decade. The work currently being undertaken, and which features the use of Wraptite as part of the specifi cation, is Phase 1.
SPECIFYING AN EXTERNAL AIR BARRIER FOR THE NEW GLASS BOTTLE CITY QUARTER Granted planning permission in March 2022, Phase 1 of Glass Bottle comprises three individual buildings with around 570 apartment units overall. 10% are social housing units and 15% are aff ordable housing units – percentages that will be maintained across delivery of the entire scheme, which will eventually deliver 3,800 new homes for some 9,500 people. Phase 1 also includes a new creche and of retail space.
400 m2 Ubiflex Finio: perfect for solar PV installations HBD12_A Proctor_Building Fabric -
Membranes_HPAdv.indd 1
Ubiflex Finio is the latest addition to Ubbink’s unrivalled range of high quality non-lead flashings. It features a unique self-adhesive double bonding system that makes it the ideal solution for in-roof solar PV panel flashings. A simple tear-off system on the back allows solar installers to install first, leaving the roofers to dress the flashing when completing the roof.
Up to three times quicker than lead to install; Lightweight & non-toxic; Perfect adhesion, even when damp; Waterproof in seconds; Consistent down to -5º
C; Fully malleable – holds its form when applied; and it is
available in grey and black. 01604 433000

carried out. However, at Glass Bottle, the Phase 1
specifi cation still included an internal vapour control membrane as part of a belt-and- braces approach. The residential apartments feature mechanical heat recovery ventilation, so an airtightness target of less than 3m3
/hr/m2 will be
desirable. The better the standard of airtightness achieved on the project, the more effi ciently the heat recovery ventilation will operate – and that all depends on the quality of the installation.
The external wall build-up of the apartment buildings is a fairly typical light steel frame structure with a sheathing board and external fi nish. Designed and specifi ed by Dublin-based architectural practice Henry J. Lyons, the Wraptite external air barrier was named within their specifi cation pack. As an airtight and vapour permeable
membrane, Wraptite can be positioned to the external side of the structure. This moves the airtightness barrier away from the internal services zone, simplifying detailing and reducing the number of penetrations through the membrane. At the same time, allowing the passage of moisture vapour eliminates condensation risk. It is even possible to use Wraptite as the sole
membrane in a wall build-up, subject to the appropriate condensation risk analyses being
INSTALLING WRAPTITE EXTERNAL AIR BARRIER ON PHASE 1 OF GLASS BOTTLE The performance of Wraptite membrane is founded on it being a simple, self-adhesive solution, with the added benefi t of Wraptite Tape being used for particular areas of detailing. This approach saves on the labour and material costs associated with meeting modern energy effi ciency requirements, which are at the forefront of Glass Bottle’s conception. Project manager, Ionel Danaca explained:
“We’ve found Wraptite is the easiest membrane to work with,” he said. “It’s the quality of the membrane and the quality of the adhesive – and not just that it is a self-adhered membrane, but the strength of the bond itself is superior.”

proctorgroup.com Keylite’s new Fixed Skylight 02/01/2025 14:27
Keylite Roof Windows has launched a new Fixed Skylight for roofs pitched from 10 degrees upwards that will allow for more daylight and a higher level of security. The innovative design, which is new to the market for 2024, will suit
single-story roofs due to its low-pitch installation and offers 44% more daylight than a standard centre pivot window. The Fixed Skylight is also compliant with Part Q of UK building regulations and meets latest guidance in ‘Security in dwellings: Approved Document Q’ to help resist unauthorised access in new dwellings. The purpose of Part Q is to make a window sufficiently robust to resist its ability to be levered open or from the glass pane being removed intact from the window frame.

The “markilux 679” is a new form of solar protection for patio roofs and conservatories. The awning has a modern cubic shape, offers plenty of shade and, with LED Lines controlled by an app, ensures an attractive interplay of light on both the cover and facade of the house. Underglass awnings are perfect for both patio roofs and conservatories. The cover, frame and mechanism of this awning type are thus particularly well protected from the weather as they are installed under the glass construction. Awning manufacturer markilux has just launched its third model, the “markilux 679”. The large awning features a modern, cubic design. It has a simple, elegant look because hardly any technical connecting elements are visible. Despite its lightweight look, it provides plenty of shade as a single-unit awning of up to 30 m2
a projection of up to 6 metres. As with other current models from the awning specialist, light also plays a role. As an option, “LED Lines” can be integrated in the cover cassette and in the guide tracks. Equipped with a light source in RGB warm white, they create a coloured to neutral light that illuminates the fabric and facade in a subtle to atmospheric way. The LEDs are convenient to control using io radio technology with a hand-held transmitter or a special app. These can even be used to define individual light scenarios. And control by voice command is also possible.
