EXAMPLES OF SUPPORTING STRUCTURES

A soffit should be mounted to a supporting structure made of dry im­pregnated wooden battens with the minimum dimensions of 25 x 50 mm. The structure should be properly levelled. The maximum spac­ing of battens should not exceed 40 cm. It is recommended that soffit boards should be mounted perpendicularly to the wall surface. The in­stallation should be performed in the ambient temperature over 5°C. The BRYZA soffit should not be mounted in places exposed to direct sunlight. 5°C Minimum installation temperature A – face board B – wooden battens C – flashing D – J strip

EAVES PROTRUSION UP TO 40 CM

EAVES PROTRUSION OVER 40 CM

INSTALLATION OF A J STRIP

J strips are mounted on the perimeter of the built roof by fixing them to the battens with spacing of approximately 30 cm. One of the ends of the soffit board may be mounted to the properly formed front board flashing instead of a J strip (fig. 8).

CONNECTING J STRIPS

INSTALLATION OF SOFFIT ELEMENTS TO SUPPORTING STRUCTURE

Soffit elements are mounted to a supporting structure by means of cor­rosion-protected screws (minimum length 20 mm and minimum head size 8 mm). The screws should be driven perpendicularly to the ground in the middle of mounting holes leaving around 1 mm clearance (in order to compen­sate for temperature-related length variations).

INSTALLATION OF PERFORATED BOARDS

Perforated ceiling boards should be mounted as every third or every fourth panel in order to obtain proper ventilation of the roof.

LOCATION OF H STRIPS

There are two methods of finishing a soffit in building corners, using H strips.

CORNER STRIP – OUTER

The use of outer corner strip makes it possible to install the soffit to various types of roof structures. It is an element which allows for aesthetic finishing of the external edges of the roof soffit and the corners of protruding roof purlins.
