Twickenham Stadium has undergone a multi-million pound redevelopment which has seen the East Stand transformed to offer six levels of contemporary hospitality and event space.  Central to the design of the exterior facade and to meet the passive fire protection and noise transfer requirements were fire stop and acoustic barrier insulation systems from SIDERISE.

The first major redevelopment of this iconic building since the completion of the South Stand in 2008, the new East Stand facilities will provide an extension to the current hospitality and conferencing facilities. Working with the building envelope contractor Prater on behalf of the main contactor Mace, SIDERISE provided a comprehensive range of vertical and horizontal cavity barriers and fire stops to maintain continuity of fire resistance between the floor slab and the external façade.

As part of the façade design and to enhance the fire safety of the new East Stand, SIDERISE recommended using their CW-FS Curtain Wall Fire Stop System with acoustic upgrades along with the SIDERISE RH ‘Open State’ horizontal and RV vertical cavity barriers. Designed and manufactured by SIDERISE, these cavity barriers consist of a pre-compressed, non-combustible stonewool lamella core, with reinforced aluminium foil faces. In addition to providing an effective seal against the passage of smoke and fire, the products will also function as an effective acoustic barrier and plenum lining.

Whilst specifying the correct product is vital, the quality of installation is equally as important. In addition to Prater’s own quality checks and to achieve the required level of performance, a simple-to-use Inspection and Reporting App from SIDERISE allowed Prater to record and assess the quality of the installation of all of the company’s standard firestop, cavity barrier and acoustic barrier systems.

With robust inspection and reporting methods essential across the construction sector, the SIDERISE Inspection and Reporting App has provided Prater with an efficient way to effectively inspect, record and seamlessly audit the quality of its installation work.  By capturing the relevant information on a tablet device, the contractor was able to highlight any issues in need of a resolution.

Commenting on the Inspecting and Reporting App, Jose Menezes, Construction Manager at Prater, said: “This was the first time we have used the App. It was simple-to-use and once the information and photos were sent to SIDERISE, they were able to provide us with additional assurance that our installation was correctly installed.”

The App allows the user to easily update data input fields, capture multiple photos for each area or element inspected and then record as in accordance with recommendations, or otherwise.  A comprehensive report is immediately generated which effectively offers feedback on the quality of installation of areas inspected as in or not in accordance with recommendations, thereby identifying areas that require remedial treatment.

The SIDERISE Inspection and Reporting App is part of a comprehensive range of services from the company’s site services team which ensures that each stage of a project, from product selection to final installation, runs smoothly.

The Siderise Group

The Siderise Group is one of the UK’s leading manufacturers of fire, acoustic and thermal insulation products, and has been for over 40 years.

The Group has two factories based in Maesteg, Wales and Hadleigh, Suffolk, and operates across 11 global sectors. The SIDERISE product ranges have become trusted throughout the facades, construction, marine, automotive and other OEM industries.

The Group is committed to the use of innovative materials and the development of designs, products and technologies for a more sustainable future. In 1991 the Siderise Group developed a unique method of mineral wool manufacture, the patented ‘HSL process’. This process gives firestopping and other products a robustness and simplicity of design that meets all functional performance requirements and facilitates superior product installation. This unique design has positioned the Group’s firestopping solution as the UK’s No.1 for the curtain walling industry for over 25 years.

The Group’s sale and distribution activities are prevalent in Ireland, across Europe, the Middle East, India and South East Asia.

The SIDERISE/Lamatherm brands

SIDERISE was established in Surrey in 1972 as a distributor of acoustic materials. The product ranges initially comprised stonewool mineral materials, acoustic foams, heavy layer barriers and damping materials. SIDERISE opened its first manufacturing facility in 1979 which specialised in the processing of mineral wool materials.

As the company evolved three brands were developed in recognition of the growing product ranges: Lamatherm to represent fire safe and thermal insulation; Lamaphon for acoustic insulation; Lamapro for specialist insulation solutions that catered to diverse industries such as HVAC, marine, rail, automotive and power generation.

Whilst the Lamatherm, Lamaphon and Lamapro brands still remain well-known to date, in 2013, in response to continued growth in the overseas markets, the Siderise Group decided to unify its products under a single brand name ‘SIDERISE’. As a consequence, the company started a product reclassification programme prefixing product names with ‘SIDERISE’ to replace the traditional 'Lamatherm', 'Lamaphon' and 'Lamapro' names.
