    Order forms


    The lamellas are delivered to the installation site in thin plastic-protected wooden boxes. Basic structure of the package is always same. Different package solutions are available for different needs. The package solutions are dependent also on delivery area.

    Storing and handling

    The number of the lamellas must be checked upon delivery. The lamellas can be storaged in their packages. The opened packages should be protected from moisture.

    The lamellas must be handled properly to prevent any damages. Cutting and any other machining of the lamellas must be performed using appropriate tools to ensure work safety and a fault-free result.


    Installation should be planned at an early stage. This is important to ensure that the ordered lamellas arrive at the site in the correct sequence.

    Before installation, the project-specific plans should be reviewed, especially the starting height, gap edges, eaves, corner details, lamella support structures and fastening methods as well as the number of fasteners. There must be an adequate number of measurement points in the lamella surface both in horizontal and in vertical direction to ensure that the vertical and horizontal lines are the same width throughout the building. After the measurement lines have been checked, the installer marks the starting modules for the first lamella on both sides of a corner in both vertical and horizontal direction. If necessary, straightening is performed. The straightness of the lines is checked using e.g. laser, and color wire markings and alignment board is used. The levelness of the wall is checked before starting the installation. There should be no measurement deviations in support studs for the width of one lamella.

    Before installation, the protective films are removed from the lamella joint area. The film is removed in the center area of the lamella only when the lamella can no more be damaged during installation. Special attention must be paid to powder coated lamellas because they do not consist protective film.

    The lamellas are fastened in steel sheet metal support studs using the fasteners specified by the designer. It is recommended to include the studs in the lamella contract and install them at the same time as the lamellas. When installing frame etc. flashings, ensure that the functionality of the structure (ventilation, water removal, etc.) is not disturbed. So called storm flashings must be used to prevent water that is rising due to the wind pressure from gaining access to the structures. Connections to other structures should always be made using cover flashings, not gasket material.

    Hot-shearing or tools producing sparks must not be used to prevent damage to the paint-coating. Angle grinders, for instance, must not be used as cutting tools. Drill shavings and other impurities must be brushed or, if necessary, washed away immediately after the work. Absolute carefulness both during the work and during the planning stage ensures the best possible results.

    Two or (preferably) three installers are required. The lamellas should be lifted from the vertical sides. Lifting from the horizontal side may open the bended lamella edges. The manufacturer is not responsible for the quality of the installation work.

    Installation phases

    Installation plan

    The following is checked at the site according to the installation plan: 

    • Positions of the lamellas 
    • Module lines 
    • Starting height 
    • Positions of window and door openings in the facade 
    • Corners

    Levelness of the substructure

    The levelness of the facade substructure is checked using e.g. alignment wire and laser measurement. The results are marked in a measurement protocol.

    Joint flashings

    The joint flashings under the support studs are installed (e.g. plinth flashings).

    Support studs

    Support studs are installed at the lamella ends and in the middle of the lamellas at distances of maximum 750 mm (recommendation). The number and type of the fasteners are specified by the designer. Both flanges of the support studs are fastened to the substructure according to the plan. At this stage the facade substructure is straightened according to the measurement protocol results (if necessary). Joints of the support studs should always be located at the supports. The starting height of the support studs is determined so that the bottom edge of the lowest lamella row can be steadily fastened to the substructure and the stud is not visible under the lowest lamella line. Adequate air passage should be left between the plinth and the lowest lamella row.

    Joint flashings

    The flashings are installed on top of the support studs.

    Lamella installation

    The installing of the one lamella row is started at the bottom and continued towards the top. The upper lamella is placed resting on the lower lamella and thereafter fastened at the upper edge.



    Suspensions should be avoided in the facade. If absolutely necessary, the supports for the suspension must be placed at the vertical joint all the way to the substructure or frame structure.

    Facade maintenance - Fasteners

    Fasteners must be checked during maintenance work. To check the health of the fasteners, open a few fasteners (unless the fasteners are concealed) in different parts of the building. Pay special attention to the general appearance of the fastener and the health of the gasket under the cover, keeping water out of the joints. Replace worn fasteners.


    Maintain a journal of facade maintenance work. Write down information such as the performed tasks, the time, the facade area involved, who performed the work and what agents were used.

    Certificates & Approvals


    A print containing package-specific information such as order, load and package numbers, contact information, content of the package (lamella type, dimensions and items) and package weight is attached to the package.

    If necessary, lamellas can also be marked during manufacture with a code specified by the customer. With the code individual lamellas can be allocated to a specific position in the building.

    Conformity with standards and quality control

    The lamellas are CE marked products in accordance with the EN 14782 standard (for paint coated and powder coated steel lamellas). The marking is presented on the package label and the attachment to the delivery note.

    Quality inspection of the panels is performed in accordance with the EN 14782 standard and the additional requirements by the manufacturer.
