CROWN BUILD OF MALDON CHOSE UBBINK’S UBIFLEX NON-LEAD FLASHING SYSTEM FOR A VARIETY OF APPLICATIONS ON THE NEW ROOF AT PRIORY COURT, A PRIVATE DEVELOPMENT IN HATFIELD PEVEREL, ESSEX.
Manufactured from aluminium mesh reinforcement, coated with a mixture of modified bitumen and additives, Ubiflex is a malleable material which can be used in most applications where lead is traditionally considered. It is available in two thicknesses (B2 2.3mm and B3 3.5mm) and finished in grey, terracotta and black, in 6m or 12m roll lengths.
Variety of roof features
The project, for Hatfield Peverel based Top Floor Property Management, involved flashings around dormer windows, and other roof features including pitched roof valleys on the complex roof structure.
Pauline Apthorp of Top Floor Property Management, said: “The roof required different lead code levels from 3 to 5 on different areas. Ubiflex B3 is the equivalent thickness of lead code 7/8, so could be used throughout the project, simplifying costing, specification and the installation process itself.”
Where Ubiflex can be used:
• Stepped flashings
• Abutment flashings
• Chimney flashings
• Pitched roof valley liners
• Dormer window flashings
• Rooflight and solar panel flashings
Savings in time and materials
Paul Benorthan of Crown Build takes up the story: “This was the first time we’d used Ubiflex and we were very impressed. The first thing that struck us, was how light and easy to handle it is compared to lead rolls. Before we even started work, we were grateful for how quick it was to get the rolls of Ubiflex up onto the roof.
Once the project was under way, in one area, we were able to fit a continuous twelve metre run. This saved a huge amount of time and removed the need for expansion joints, making big material savings and reducing wastage. We ended up with only 600mm of excess Ubiflex over the whole project.”
Not only is Ubiflex 80% lighter than lead, it’s also completely non¬toxic, so health & safety is improved on two counts – and the light weight can bring structural advantages, too.
No scrap value
Another benefit of Ubiflex is that unlike lead, it has no scrap value so deters thieves but is still aesthetically pleasing. Ubiflex material is sustainable and recyclable.
Specify with confidence
In wind tunnel testing at the BRE, Ubiflex B3 has been demonstrated to resist uplift at wind speeds of up to 110 miles per hour when installed with High Tack. It is also BBA certified (08/4577) so the system can be specified with confidence for most applications, even in coastal areas. For further information, contact Ubbink on 01604 433000
