LINDAB Safe Click Self-Locking Duct System Speeds Refurbishment Of Oxford University Offices

Just one click and the job is done

Lindab's new Safe Click system is purpose designed for integrating fittings into circular ductwork. It's an ingenious solution that speeds installation, while offering air tightness to Class C or above.

Both those objectives have been achieved in a major office refurbishment project in the centre of Oxford.

Wellington Square in the heart of the city provides a new home for part of the central admninistration of the University. The upper half of a four storey building in the Square has been completely refurbished to provide new offices for Oxford University Estates Department.

Ductwork engineers Air Aquality Services Ltd have installed over 900 metres of Lindab spiral ductwork in the ceiling voids. Conditioned air from the roof mounted air handling plant will be supplied into the rooms spaces via perforated ceiling diffusers.

Fast and efficient
Alex Gaeta of Air Quality Services was seeking a fast and efficient means of connecting bends, tees, elbows and other fittings on the spiral ducting and Lindab Safe Click offered a custom matched solution.

"Speed was essential for this fast track project, but we were determined not to compromise the air tightness of the system.

Lindab Safe Click does what it says on the tin. It’s quick and easy to install and gives a good seal against air leakage.

The fact that it needs no sealant and so few screws also results in a neater finish.”

Brand new
Lindab Safe Click is a brand new system that reduces the need for special tools, screws or rivets. Pre-sealed Lindab Safe fittings are connected to the ducts by means of interlocking ”notches” created on site with the aid of a special Lindab Cutting bench. Duct and fittings simply slot together with a simple click – it’s as easy as putting on a seat belt.

The new system ensures fewer holes from screws or rivets in the ductwork and thus less chance of air leakage. Ducts are also easier to clean and the risk of bacteria growth is reduced. No sealants are required, so on site safety is improved and clearing up after ductwork installation is completed takes far less time and labour.

Perfect complement
Lindab Safe Click makes a perfect complement to the existing range of Safe fittings, which is fast becoming a standard solution in the UK. Lindab’s Safe system comprises a complete range of pre-sealed components designed to create a circular ductwork system with minimum leakage in the shortest possible time. The unique double-lipped gasket ensures a perfectly sealed joint every time - without the need for any additional sealants. Lindab Safe fittings also feature rolled edges for greater dimensional accuracy and to make them more rigid and safer to handle and install.

Lindab Safe is much quicker to install than conventional taped and sealed system. A recent test programme conducted by BSRIA showed Safe cut installation time in half and cost 20% less when compared to the traditional approach!

Crucial savings in air leakage were just as significant. At a static duct pressure of 500 Pa the air leakage rate from the Lindab Safe ductwork was 43.8% of that from the system constructed with traditional components. Independent tests carried out in Germany by TUV Rheinland have confirmed even better results for new Safe Click.

Leading supplier
With a turnover approaching £60 million, Lindab is the UK’s leading supplier of flexible and spiral ductwork and components with state-of-the-art production facilities in both Britain and Sweden. In addition to its four major UK manufacturing plants the company produces spiral ductwork at no fewer than fifteen locations across the UK. Fans are also a major part of the portfolio – Lindab is one of the UK’s leading fan distributors with a comprehensive range for all domestic, commercial and industrial applications.

To ensure same-day availability, Lindab carries comprehensive stock, including fans, throughout the country. Complete packages of equipment including ductwork, fans, flues, sealants, grilles, fire dampers etc can be assembled at the branch ready for delivery to site, or collection by the contractor's own vehicle.
