GypLyner Encase is a fire protection system providing fire resistance to structural steel columns and beams. Installation is quick and easy due to the use of simple clip fixings to secure the framing sections. The system will protect all universal column and beam sections with flange thicknesses between 6mm and 28mm. GypLyner Encase will also protect many joist sections, portal frames, and castellated beam sections. It can be used in any type of building where encasement to structural steel is required.

Passive fire protection is a vital component of any fire safety strategy. It safeguards people’s lives and limits the financial impact of damage to buildings and their contents. The protection of the superstructure from fire is especially important, as the whole building’s stability depends on its integrity being maintained. Our steel protection systems provide fire protection to structural steel columns, beams and joists and are able to accept standard methods of finishing; tape and joint, or Thistle skim plaster, to match surrounding elements. An aesthetic finish is not necessary with the GypLyner Encase system to maintain its fire performance.

Key facts

  • Fire Performance from 30-120 minutes.
  • High levels of acoustic and thermal insulation can be maintained with detailing of abutments between GypWall partition systems and GypLyner Encase encasements.
