Timber Siding and Weatherboard

Vertical application
Aluminium
Fast installation
Visible fix

For vertical siding timber façade design, the horizontal timber rail is fixed directly to the vertical rails using self-drilling screws. The vertical timber siding or weatherboards can then be fixed to the horizontal timber support using wood screws, or nails as specified by the project engineer. Where the façade is horizontal, fix the timber directly to the vertical aluminium rail using countersunk self-drilling screws.

Using an aluminium façade sub structure, opposed to timber, provides benefits such as; reduced weight, material longevity, improved engineering calculations and resistance to fire. View the downloads section for various designs for fixing timber to aluminium structures.

Where the timber members are butted together, both the 60mm and the 110mm faced T rail will provide the correct dimensions, relating to surface area in contact with the panel and movement between the abutting joints. Depending on the material type, timber facades require vertical support at 500mm to 600mm - for all vertical centre support generally use the L rail 51x61mm section.

    Typical bracket configuration uses the Fixed Point bracket at the highest position on the vertical rail to support the façade vertical dead loads. The Sliding Point bracket is used typically on all other positions on the vertical rail to absorb the project wind loading. Bracket configuration is specified by FischerBWM engineering department.

    RJ & Fischer offer a standard, available ex stock UK, range that covers most design requirements.

    All rails available to specific RAL colours in Qualicoat on an order to order basis.

    Bracket and rail systems from Fischer are interchangeable based on the project requirement. 'Helping Hand' brackets from SystemEVT are the example in the image, the most cost-effective bracket selection from the range. To achieve improved thermal performance to concrete substrate use FischerBWM ZeLa brackets.

    FischerBWM offer Europe’s largest range of Helping hand brackets which have been designed to help achieve the U-value. Bracket systems range from the ZeLa range, designed to achieve passive house levels of performance, to standard L brackets that suit most project requirements in the UK.
