Fascia and Soffit Installation Instructions

Soffit installation :

Step 1:

Each soffit or fascia panel’s protective film is printed with directional arrows. Ensure panels are fixed with the arrows pointing in the same direction to ensure a uniform surface appearance. Remove a small area of the protective film from the locations of all fixings to prevent it being trapped underneath the head of the fixing. See Fig. 1

Step 2:

Fix Soffit support trim FF30 to background at 600mm centres and slot soffit panel into Soffit support trim FF30. Pre-drill pilot holes and fix soffit at 600mm centres in rafter / truss ends with colour matched polypins, code SC670 at the front. Polypins should be positioned to be concealed by the bottom front return edge of the fascia. See Fig. 2

Step 3:

Joints between abutting panels are made using ‘H’ section joint trims. See Fig. 2

Step 4:

Install next soffit panel; ensure a 4mm expansion gap between panels. Fix horizontal timber battens between rafters / trusses for support and alignment at joints.

Fascia installation option 1:Mechanical fixingStep 4.1: Option

Direct fixing to rafters: For fascia panels supporting guttering, fix with two Nr 50mm poly nails SC280 above the gutter line at maximum 600mm centres. For fascia panels not supporting guttering, fix with two Nr 30mm polypins SC670 at maximum 600mm centres. Additional polypin fixings will be required for fascias over 250mm deep.

Step 4.2: Option

Fixing to timber background: Fix fascia panel at maximum 600mm centres with two Nr 30mm polypins SC670 above the gutter line.

Step 5:

Abutting ends must be jointed with the appropriate H-Section joint trim.

Step 6:

Ensure there is at least a 2mm expansion gap where fascia panel is inserted into the H-section joint trim.

Step 7:

Finally, remove the protective film within 90 days of installation.

Marley Alutec recommends the use of SikaTack Panel Adhesive System when bonding panels.

Not all backgrounds are suitable for a direct secure bond, therefore bonding plates should be mechanically fixed to the background at maximum 600mm centres. Bonding plates are supplied 75mm wide in 3m lengths code FY40 for site cutting to required lengths.

Step 8:Fix bonding plate FY40 at 600mm centres using minimum 3 Nr stainless steel flat head annular nails or countersunk screws.

Step 9:Strip off the protective film from the bonding plates and apply one thin coat of SikaTack panel primer to the bonding plates and corresponding areas to the rear of the fascia board. Allow at least 30 minutes for the primer to dry.

Step 10: Apply the self-adhesive fixing tape vertically to the full length of the bonding plate 5mm in from the edge. This fixing tape is only intended to hold the panel in position until the adhesive is fully cured. See Fig. 4.

Step 11:Apply Sikatack adhesive to the bonding plate using the triangular nozzle supplied, applying a 10mm high bead at least 5mm from the edge of the plate.

Important Note: Do not apply adhesive in damp/wet conditions or temperatures below 5°C. We also recommend discreet pinning to the top edge to support the weight of the panels as an additional safety measure.

Step 12: Remove the foil from the fixing tape, and then carefully offer the fascia panel into the required position to make contact with the beads of adhesive, but without touching the fixing tape. When the panel is in position, press firmly until it makes contact with the fixing tape. We recommend this operation is carried out by two operatives. Fitting the panel must be completed within 10 minutes after application of the adhesive.

Step 13.1: OptionH Section Joints: Abutting ends must be jointed with the appropriate H-Section joint trim.

Step 13.2: OptionPointed Joints: To achieve a neat silicone joint apply masking tape to both edges, point silicone into the joint, code SC103 and smooth flat. Note: Silicone must make contact with the rear bonding plate. Finally remove masking tape.

Step 14: Finally, remove the protective film within 90 days of installation.

Fascia and Soffit Installation Instructions

General Guidance:

PreparationTimber rafters/trusses must be at maximum 600mm centres. Rafter ends must be vertically plumb and in linear alignment and if necessary, suitable packing must be used. All abutting joints require a support batten behind for alignment.

Fascia: If mechanically fixing, backing boards are not required and fascia panels direct fixed to rafter / truss ends at maximum 600mm centres. If bonding fascias, a moisture resistant plywood backing board must be installed.

Soffit: Support along the wall edge using Soffit Support Trim FF30 or wooden batten mechanically fixed to the brickwork at 600mm centres. The front edge of the soffit is pinned to the underside of the rafter / truss. On deep fascias, additional framing is required.

Bargeboard: Construct a suitable timber background framework for fixing bargeboards at maximum 600mm centres. Appropriate framing is also required at junctions between fascias, bargeboards and valleys.

Bending / FoldingOn-site forming of external / internal corners or box ends can be achieved using a suitable metal router bit to form a v-shaped groove to a 3mm depth in the front or rear face of the panel. The groove must then be filled with Joint Sealant SC101 / SC103 and folded to the required angle.

Cutting / DrillingCut or drill holes using typical carpentry hand/power tools. For circular saws, use a fine toothed or dedicated aluminium blade. Ensure the panels are placed onto a clean and flat surface and adequately clamped. De-burr all cut edges with a fine file.

VentilationFor ventilated eaves, soffit panels with vent slots are available. Standard vent slots provide a continuous ventilation area of 25mm. Other size vent slots are available on special order.

Handling & Storage Fascia and soffit panels have a peel-off protective film to the painted surfaces. It is recommended that the film remains on the panels throughout the installation process and removed on completion, within 90 days of exposure.

The protective film gives limited protection so care must be taken not to damage the panels during handling or installation. If the film becomes scratched, the scratch may not be deep enough to have damaged the paint surface, however it may leave a black mark on the painted surface, which can be cleaned off with a cloth and Alutec solvent cleaner, code SC108.

Touching up visible scratched surfaces with colour matching paint is not recommended, as the touch up paint will in time discolour and be visible.

Panels should be stored on a flat surface and stacked so as to not to bear down on the bent edges and be covered if stored outside.

Environmental Ensure all packaging is disposed of responsibly in accordance with current waste disposal regulations. Aluminium composite material is fully recyclable and therefore off cuts should be disposed of at metal recycling depots.

Safety The relevant safety regulations are outlined in the Health and Safety at Work Act 1974 and should be followed.

Refer to the Approved Code of Practice (ACOP) Construction Design and Management Regulations 2007.

Handling aluminium composite panels does not pose any known hazard, however the wearing of protective gloves when handling is recommended.

Hazard instructions relating to joint sealant and solvent cleaner are printed on their respective containers and COSHH sheets are supplied with each consignment of goods and are available on request.
