GreenCoat® S280 Snaplock® Seam
Description

The Snaplock® seam system is extensively used in Europe and the United States of America, where the system has proved itself in the extremely varied climate. The system gives an aesthetically pleasing finish whilst avoiding the industrial finishes found in other seam systems.

Features and benefits:

  • Manufactured from robust, commercial grade steel.
  • Harder wearing, flatter panel than GreenCoat® PLX.
  • Ultraviolet (UV) light and scratch resistant.
  • Seams are available in 25 or 38 mm formats.
  • GreenCoat® colour coated steel products from SSAB Swedish Steel use Swedish rapeseed oil in the coating, producing a sustainable colour coated steel for exterior buildings. The patented BT coatings (Bio-based Technology) offer environmental advantages (100% recyclable) and increased performance.
  • The Snaplock® seam system can be laid on a ventilated timber substrate, composite panel or direct on insulation, using special warm roof fixing clips.
  • Snaplock® is much simpler and requires less skill/ hand tools than the traditional standing seam. The profile contains an undercloak and an overcloak – the undercloak side is fixed with a stainless steel fixing clip with the overcloak side then snapped into place.
  • The system can be provided as a complete roof kit including all flashing, matching rainwater products and ancillaries.
  • Also available in GreenCoat® PLX lightweight corrosion resistant steel.

Substructure:

Snaplock® can be mounted on all roof build-ups, the only pre-requisite being that it is fully supported. Suitable substructure materials:

  • Ventilated 18 mm-thick weather and boil proof (WPB) plywood.
  • Ventilated oriented strand board OSB3.
  • Hard metal board.
  • Composite panel.
  • Rigid insulation.

Underlay:

ISO-Mat Pro® underlay is recommended by the manufacturer depending upon the application.

Clips:

  • 25 mm seam: SM-EH-Snap-25 (SM-EDH-Snap-25 for fixing to rigid insulation).
  • 38 mm seam: SM-EH-Snap-38 (SM-EDH-Snap-38 for fixing to rigid insulation).
  • Flashing clips: SM-ELH-27.
