Doors and windows designing

The construction of aluminium doors in the vast majority of systems causes a significant narrowing of the clear opening in relation to the original opening made for fitting the joinery.

In addition to the width of the frame profiles, the width of the door leaf should be taken into account, which, when opened to the angle of 90°, is located in the clear opening, causing its narrowing. In individual systems, the width occupied by the structure in the opening varies slightly. However, it can be safely assumed that for single-leaf doors, the opening made in the wall should be 26 cm wider than the target clear opening. For double-leaf doors, the opening should be 36 cm wider. However, in order to obtain the required passage height, the opening in the wall should be 11 cm larger. The above dimensions do not include additional elements mounted on the door, e.g., anti-panic fittings, which also narrow the clear opening.

Yawal profiles and the fitting systems allow for the construction of large-sized structures.

The maximum size of leaves/sashes depends on their weight, function and system. For example, windows with a height of up to 3000 mm and a weight of up to 200 kg can be manufactured. System catalogues and assembly catalogues contain a number of normograms that facilitate the selection of appropriate fittings based on the type, width, height and weight of the leaf/sash. For structures exceeding the specified sizes, individual consultation of solutions is required.

Thermal parameters of single-chamber glass panes are usually insufficient to meet the current requirements of thermal protection for windows and doors used in rooms with a temperature above 16°C. The solution is to use double-chamber glass panes.

Acoustic insulation depends on the glazing used, the system and the method of the structure assembly. Finished structures usually have an acoustic insulation of approx. 1-4 dB lower than the glass used.

The minimum width of the structure often results from the minimum width of the glass pane and machines used for the production of joinery (corner crimping machines) or restrictions imposed by the used fittings. It is usually approx. 400 mm. The minimum width of a leaf equipped with an anti-panic bar is 450 mm.

The SAP system (Fire Alarm System) is a set of various interconnected elements forming an installation that can detect fire, start an alarm and initiate other actions to stop or limit its spread.

A number of sensors and devices are connected to the Fire Alarm System (SAP) to ensure the safety of use. These can be, e.g., actuators for smoke exhaust flaps and windows, fire-resistant doors, ventilation windows and doors. The listed elements may be SAP components. The solution can be used in any Yawal system.
