Renderplas PVC beading solutions for a sustainable future


the production of millions of linear meters of Renderplas PVC beads every year used for rendering, plastering, dry lining and external wall insulation, actually contribute to a sustainable environment rather than harming it. From conception 30 years ago, Renderplas


M


have worked hard to innovate and lead the PVC bead industry in the field of sustainability. All of our white PVC beads are made predominantly from waste material from the vast manufacturing process of building components, making them sustainable and a great development in the way that building components can perform. We are proud to manufacture our PVC


beads in the UK and to provide a low carbon alternative to cheap imports. Quality is assured, Renderplas beads will not perish and

more, and they last longer than metal. Even if the render needs replacing or when the building reaches end of life, our PVC beads can be removed and easily recycled. The first PVC bead manufacturer to complete a full life cycle assessment (LCA) providing Ecopoint calculations for our products, Renderplas PVC beads achieved the top eco-rating available of “excellent” in an independent environmental profile report. Renderplas beads are ecologically benign and comply with REACH legislation as all harmful additives have been removed.


they will not need replacing. Our PVC products require far less maintenance than traditional building materials, they are also easier to cut and handle than metal and so produce far less waste during installation. Renderplas PVC beads are designed to last as long as the render, typically 25 years or

Comfort and safety from SE Controls at sixth form centre

A


building is constructed as a three-story pod located in the centre of the school’s Hammond Quad, while a further single storey was added to the existing building at the southern end of the quad and the previously open space covered with a glazed roof. In addition to meeting the building’s fire protection specification, which demands that fire fighters must be able to actuate the system and disperse smoke on arrival, via a manual call point at the main entrance, SE Controls also had to integrate the ventilation solution into the BMS to provide comfort ventilation and temperature control during


new sixth form study and careers centre at Hampton School in South West London is using a combined


day-to-day operation. To achieve this, 20 SHEVTEC louvred smoke ventilators were installed at high-level in a rooftop plenum and operate as a four-zone system via a dedicated controller, linked to the BMS. This design enables proportional actuation of the vents so that they can be opened in stages depending on the temperature within the atrium. The control panel also incorporates a 72-hour battery backup for failsafe operation in the event of power interruption or failure. As the ventilation system must also operate


in the event of a fire, all the ventilators and control systems supplied by SE Controls are manufactured and tested in accordance with BS EN 12101 part 2 and part 10, as well as being compliant with other relevant product legislation, regulations and standards. Although the louvres are all 1,280mm


in height, five different widths were used on the project, ranging from 1,430mm to 1,854mm, enabling them to fit within the structural glazing system’s dimensions and

ensure the ventilation airflow requirements are met. In normal comfort mode, IP65 rated


electric motors open and close the louvres depending on the level of cooling and ventilation needed within the atrium, which is managed by the school’s BMS. If the building’s fire alarm system is actuated, it over-rides the BMS and all the vents are closed until the fire services arrived and actuate the system to manage how the smoke is cleared to assist fire-fighting procedures.
