Window installation and dismantling in Stuttgart, Germany
 
Our fitters

Our Service Technicians have more than the average experience in dismantling and installing windows. We have a healthy balance of young and experienced fitters. Our team from the technology department as well as all of our service technicians regularly take part in training courses.

Dismantling old buildings

Existing windows in older properties are carefully sawn into pieces using a sabre saw (like a jigsaw but more powerful) without causing any damage to the infrastructure. The inner plaster, exterior plasterwork, any wall tiles and sills are left undamaged. After thorough cleaning of the working area, installation of the new window can begin.

Assembly in old buildings

The windows are mounted correctly horizontally and vertically. The distances of the mounting points to existing brickwork are determined and will depend on the window system chosen (wood, PVC or aluminium).

Assembly in new buildings

The windows are mounted correctly horizontally and vertically. The distances of the mounting points to existing brickwork are determined and will depend on the window system chosen. Various installation methods are possible in new buildings. Even the position of the window within the wall can be optimised in order to achieve optimum thermal insulation. The internal sealing is usually carried out using a vapour diffusion-proof sheeting. This sheeting can be used by subsequent workers, e.g. the plasterer, as base.

Disposal of old windows

Within Germany we only work together with approved companies and members of the German Association of Steel Recycling and Disposal e.V. in order that materials for waste disposal are correctly disposed of or recycled according to national regulations.

General notes on sealing

The three insulation levels outer, central and inner are subject to the following basic measures:

The inner insulation separates the room from the external environment and must be vapour-diffusion proof.

The central insulation barrier between frame and wall must be completely filled with thermal insulating material.

The outer insulation serves as weatherproofing level and must be watertight against driving rain at all times and also be permeable for vapour diffusion.

Insulation materials of the 3 levels

The inner insulation can be carried out with vapour proof sheeting or, as is often used in older properties, a permanently elastic sheeting material. The central layer can either be executed using 1-component PU-foam or an alternative filler such as cotton fibre. The outer layer can comprise pre-compressed insulation strips or a vapour-permeable sheeting.

Insulation of the window presents an important and effective protection against any subsequent damage to the building infrastructure. Windows must be insulated according to modern building rules and regulations. There is one basic rule: internally more insulation than externally.
