Mithilesh Kumar, Director - Layher Scaffolding Systems
Our brand promise of more speed, more safety, more proximity, more simplicity, and more competitiveness in the long-term, are the values that we’ve been living by for over 65 years. With our innovative systems and solutions, we’re making scaffolding construction even simpler, more economical and, above all, safer.

Layher Protect System is ideal for Temporary Dustproof Wall; this dustproof enclosure system effectively keeps out dust from construction and looks good as well.

The Layher Protect-System is a cassette enclosure system for the most stringent requirements in environmental conservation, traffic protection, and noise insulation. The airtight connection of the cassettes enables their use as a dust and noise protection wall, for example, during asbestos clearance or restoration work. They can also be used all the year round for buildings, scaffolding covering, façade refurbishment, sandblasting work, partition walls, etc.

The Protect-System is compatible with Layher Allround Scaffold equipment. It comprises individual 1.0 m high cassettes in the length of the corresponding scaffolding bay, and holders matching the scaffolding system. The individual cassettes are made of profiled aluminium frames which have a galvanized steel sheet attached to them. The cassettes are sealed off from one another by an all-round rubber section. In the case of translucent cassettes, the steel sheet is replaced by a transparent rib-reinforced panel. The cassettes can also be designed as sound-proofing cassettes by providing an insulation mat on the galvanized steel sheet.

Site protection is becoming increasingly important in construction projects. To avoid site shutdowns, we have to provide protection against the effects of weather, and also protect pedestrians from dust, noise and falling objects.
Shoppers nowadays are looking for adventure, and this has brought about a number of changes to the design of shopping centres. The Weser Park shopping centre in Bremen, which opened in 1990, reflects this trend: as an ‘oasis’ of wellness, it has a bowling alley and a cinema hall. To remain competitive in the future, this shopping centre, one of the largest in northern Germany, is being renovated and expanded at considerable expense. But business must continue. In order not to spoil people’s shopping experience during this period, a temporary partition wall has been set up to protect them from dust and prevent them from entering the construction site by mistake.

This was a challenging task for a company specializing in property and project management. Site protection is becoming increasingly important in construction projects, especially in shopping centers like Weser Park which are highly frequented. When we erected the temporary partition wall we had to keep a number of factors in mind: we had to assemble it quickly to keep to our schedule; and we had to give it an attractive appearance in keeping with the prestigious surroundings. These requirements cannot be met by ordinary tarpaulins.

Application of Protect System
The system consists of a construction kit made up of cassette elements. Depending on the needs, they are provided with a galvanized steel sheet, a translucent plastic ribbed panel, or real glass. This permits work in daylight conditions and allows visitors to peek behind the scenes. By means of cassettes of different lengths and special corner elements, we can adapt temporary partitions made from the Protect System to the given geometry. An all-round rubber seal on the cassettes ensures a neat and precisely fitting connection to the adjacent elements. The temporary partitions can thus seal off individual areas and allow operations to continue without obstruction – both in front and behind them.

Removal of individual wall cassettes
Layher Scaffolding SystemsThe Weserpark shopping centre in Bremen
To remove individual wall cassettes, the appropriate upper holders of the wall cassette to be removed must be dismantled and the upper cassette tilted outwards. The lower wall cassette can now be lifted and removed. The removed holders must be bolted back on in their old positions. To remove the cassettes, the handrail of the scaffolding must not be removed, unless the risk assessment by the scaffolding erector calls for further measures to prevent falls.

Making the transition to the building
For the transition from the wall cassettes or translucent cassettes to the building, the ground or the roof, or for corners, the connection profiles can be fastened both horizontally and vertically to the cassettes. The connection profiles permit the connection of a slide-in tarpaulin, metal sheet or wooden board.

For three sections with a total area of 700 sqm, the team first put up Layher Allround Scaffolding as a substructure. The system’s modular structure assured an exact match to the shape of the building, and its ingenious bolt-free wedge head connection technology saved time during assembly. The wall cassettes and real glass cassettes were easy to mount, even in corner areas. To keep disruption of business to a minimum, the scaffolding erectors worked night and day and the 8-metre-high partition walls were completed in just a week. The result was an efficient site protection structure that provided ideal conditions for renovation and modernization of the shopping centre.
