Innovative IBT system chosen for London residential project

Parker Bromley is a well established, family owned business specialising in MEP systems. As part of the London development project it has been tasked to deliver embedded MEP solutions including heat recovery (MVHR), smoke ventilation and fire alarm systems as well as an ‘Energy Centre’ to service each apartment block. It was tasked with minimizing installation time to help keep the overall development project to deadline.

Jody Parker, Director at Parker Bromley, explains the challenges involved: “Concrete construction is a fast, effective and aesthetic method for building apartment blocks such as the ones being built here. However, when casting panels onsite it is important that considerations are made for the necessary wiring and electrical connections.

We chose to specify Spelsberg’s IBT system of junction boxes, which fit to the metal formwork before the concrete is poured. When the concrete is set and the formwork removed, the face of the IBT housing is visible. All the required housings and conduits are then in place, ready for cabling and installation.”

A key element of the IBT system is the integral sealing, which prevents concrete fines from getting inside the electrical components. This uses a patented diaphragm system which, after the conduit is inserted, returns to its original position and provides strain relief and sealing without the need for special grommets. Conventional housings do not have such a seal, a sealing arrangement would have to be fitted in-situ, a difficult and costly process.

The IBT products are made from halogen-free, high-temperature resistant material which is designed for a long, trouble-free life. The range is available in a wide range of sizes. With more and more projects now requiring extra low voltage (ELV) transformers for LED lighting, loudspeakers and network communications cables, Spelsberg has also developed the complementary IBTronic range.

Parker continued: “We first approached Spelsberg at the recommendation of another one of their customers. We knew the solutions we were looking for, we just needed to find a supplier that we could trust to deliver quality housings to the right time frame. The customer service from Spelsberg has been perfect, helping us to stick our company ethos of total customer satisfaction.”
