Application

For use on roof coverings and façade cladding.

Description

Falzinc is a corrosion resistant aluminium strip and sheet for roof coverings and façade cladding. Falzinc is suitable for a wide range of applications including private housing construction, public buildings, historic buildings, sports and leisure facilities, commercial buildings as well as urban renewals and regeneration schemes.


Composition:

Core of sea-water resistant aluminium alloy with a prepatinated zinc surface to both sides. This metallic surface layer has the ability to protect areas of the surface damaged during seam forming or installation.


Protection:

Falzinc is supplied with a protective film. This protects the surface against dirt and damage during storage and installation.


Folding:

Falzinc can be processed with all devices and machines that are commonly used.


Longitudinal joints

Roof coverings: The types of joints commonly used are:

  • Double Standing Seam.
  • Batten rolls.
  • Angled Standing Seam (steep inclines only).


Wall coverings: The types of joints commonly used are:

  • Angled standing seam.
  • Double standing seam.
  • Batten cap.


Roof Structures and Ventilation:

Falzinc is suitable for covering ventilated roof structures. The advantage of this roof construction is that minor amounts of moisture that might penetrate into the roof structure from the inside of the building due to an ineffective vapour control layer, will be safely carried off in the ventilation cavity. Falzinc is also suitable for covering non-ventilated roof structures if the vapour control layer prevents moisture penetration of the construction.


Roof Pitch:

The recommended minimum roof pitch for Falzinc coverings is generally 7°. With appropriate additional sealing measures, lower roof pitches down to 3° are technically possible.


Support Structure:

Falzinc must be fully supported throughout its entire area. The deck must be even and suitable for the attachment of clips using nails and screws.


Underlay:

Separation or ‘slip’ layers are used to:

  • Prevent corrosive influences from aggressive wood protection agents or alkaline influences from fresh concrete or mortar.
  • Aid movement due to thermal expansion/ contraction.


Length of strip:

For normal installation, this is limited to 10 m, with use of appropriately designed fixing components. Length up to 15 m is possible; above that transverse joints are required, the design of which depends upon the roof pitch.


Cover Width:

The cover width of the installed strip is the coil width minus side laps. For a coil width of 600 mm with a double standing seam fold, the two side laps would be 35 mm and 45 mm. The overall cover width would therefore be 520 mm with a double standing seam height of 25 mm.


Fixing:

Standing seams joints are fixed with clips folded into the seam. For Falzinc, clips are one-part or multi-part stainless steel (at least 0.4 mm thickness). Fixing must to allow for thermal expansion. The number of clips required differs according to wind loads. Maximum distance between clips is 500 mm.


Features and benefits:

  • Very high corrosion resistance.
  • Light weight.
  • Ease of handling and installation.
  • Optimised properties for skilled metalworking.
  • Can be combined with construction materials of aluminium, titanium and zinc.
  • Highly distinctive, traditional weathered zinc appearance.
  • Lowered weather erosion rate than zinc.
  • Excellent durability due to the sea-water resistant aluminium base material.
  • Fully demountable and recyclable.
