Extraspace Solutions says it specialises in meeting the challenging demands of modern construction – especially when space is at a premium – by offering versatile, cost-effective and highly practical modular systems.
One of its new projects is a €20m office development for Pramerica Systems Ireland that consists of 300 hi-tech modules – with the potential to increase this number incrementally to 420 as the business continues to grow.
Each three-storey block is 51m x 24m and each steel-frame module measures 12.2m x 2.9m.
Designed to achieve specifications above regulations, each unit aims for maximum efficiency and benefits from DuPont building membranes. The advanced breather membrane Tyvek Soft is used as the external weather-proofing shield (and has been specially branded with the Extraspace Solutions logo) while the air and vapour control layer DuPont AirGuard Reflective enhances the airtightness of the structure.
Capitalising on the advantages of off-site construction methods, the modules are delivered to site already wrapped in these membranes and the envelope is then fully sealed using DuPont tapes and accessories, especially where any apertures and penetrations may have been made. This solution creates a reliable water shedding external layer in the form of the unique and enduring properties of DuPont Tyvek, which also allows water vapour to escape naturally into the atmosphere.
Once on site, the modules are then externally clad with a rendered system and core insulation is added to the interior, safe in the knowledge that it will be protected for the long term and its performance enhanced by the market-leading membrane.
The interior facing walls of the pods are then sealed with DuPont AirGuard Reflective, a metallised AVCL that offers 100% airtightness and low emissivity, to enhance both thermal efficiency and interior comfort.
Commenting on the use of DuPont AirGuard, Stevin Tedstone, of Extraspace, said: “It was chosen for its overall performance as well as being the only reflective AVCL with both a warranty and a BBA certificate.
We have long experience of working with DuPont Tyvek which gives us peace of mind. What’s more, when architects and professionals know we are using DuPont membranes, it ticks all the boxes as it guarantees all the specs and paperwork data will be in place.”
