Building Envelope Urban Seam® Façade

Urban Seam® Façade

Limited combustibility wall system suitable for use on buildings over 18m tall.

Tata Steel has taken its non-combustible Urban Seam® cladding sheet and incorporated it into a façade system comprising products that are classified as A1 or A2-s1,d0 and therefore meet the requirement of the latest Building Regulations.

Fully supported standing seam cladding systems are typically supported by and fixed back to continuous plywood or OSB backing board. In the Urban Seam® Façade system the combustible backing board has been replaced by a non-combustible profiled steel deck. The lightweight profiled steel deck is fixed back to a helping hand rail and bracket system which in turn is fixed back to a typical steel frame system.

The system has been independently verified by full scale CWCT testing for wind resistance, water tightness and hard & soft body impacts and also includes British Board of Agrement Approval for Colorcoat Prisma®.

Made in the UK

Manufactured in Shotton, North Wales, Urban Seam® standing seam façade system consists of an A1 rated Colorcoat Prisma® pre-finished steel fixed to a Trisobuild® D32s carrier sheet. This construction makes the system ideal for multi-occupancy apartments, student accommodation, hotels, and mixed use buildings. It also future proofs the cladding element from changes in building regulations.  The Colorcoat Prisma® finish provides a stunning, but robust, aesthetic finish, with a contemporary colour palette. Quick build times are possible with neat crisp finishes to complement design and build choices.

Urban Seam® is manufactured from Colorcoat Prisma® which uses a 3 layer coating technology to provide the best possible colour protection (from fade) on the market, and has undergone rigorous testing for its resistance to corrosion and uv fade.  The 3 layer process has enabled us to supply different colours – matter ‘matts’ and more sparkly ‘metallics’.  The new metallic colour names have been named with the prefix ‘Seren’ to give a nod to their Welsh heritage.

Our hand samples can assist in colour selection and finalising product specification.

For over 25 years the Confidex® Guarantee from Tata Steel has remained best in class.

Confidex® is the product performance guarantee for Colorcoat Prisma® which is used to manufacture the Urban Seam profile. It offers the longest and most comprehensive guarantee for pre-finished steel available in Europe with Colorcoat Prisma® being guaranteed for up to 40 years.

The Confidex® Guarantee is project specific and upon registration provides a contractual relationship between Tata Steel and the building owner meaning that in the case of a claim the contact with Tata Steel is direct rather than having to go through the supply chain, saving time and money.

Due to the superior aesthetic properties of Colorcoat Prisma® a colour guarantee is uniquely included as part of the Confidex® Guarantee for up to 20 years (see terms and conditions). This includes all 29 standard colours in the range, subject to location and use.

The Confidex® Guarantee is transferable, so should the building owner change it is simply a case of filling in the form on the back of the guarantee certificate and posting back to Tata Steel.
