VERMIDUCT^®

Access Panels
(Interior & Exterior applications)

Product Description

LAF Access Panels have been designed for incorporation into Air Handling Ductwork, Masonry Elements or Fan Enclosures. The panels are screw fixed to a steel frame which in turn is fixed by means of masonry anchors or self-tapping screws into the masonry opening, sheetmetal substrate or Trimesh^® Frame. Note that LAF Access Panels are not air tight, consequently on air handling ductwork fire rated panels can only be installed over approved air-tight hatches.

Sizes

LAF access panels can be manufactured to suit the Designer’s requirements, The maximum allowable size is 1200 mm x 1200 mm for a 2 hour FRL.

Recommended Uses

Access panels may be used in conjunction with Trimesh^® construction for incorporation in Fan Enclosures, Ceilings, Bulkheads, Air Plenum, Lift-motor room as well as plant room hatches. Access panels have been tested in all modes and consequently may be installed in both a horizontal and vertical plane. (1)

Application Instructions

Access panels cater for openings from 1.2m x 1.2m down to the smallest opening possible. The exposed face of the access panel is lined with sheet metal for added protection against wear and tear. The panel is affixed by means of self-tapping screws through to a metal C-section which surrounds the duct inspection hatch. Normally the C-section frame is fixed to the sheet metal before spraying, and includes a 2.5 mm perimeter tolerance which provides a hard edge to which the spray material is terminated. For openings in masonry construction the steel frame must be anchored with non-combustible masonry anchors.

When installing access panels to air handling ductwork, the surrounding frame should be installed, followed by the spraying operation and ultimately, installation of the access panel tray.

The entire operation should be carried out by approved applicators, familiar with LAF products.

LAF Access Panels may be painted however suitable sealers and paints must be used. The panels may be used for interior use unless stainless steel or fully Galvanised trays are used. Although Trimesh^® is Galvanised and normally resistant to water, it is advisable that in exterior applications and wet areas, the spray material face be top-coated with a water-repellent membrane to provide protection to the spray and metal edges of the tray and Trimesh^®. If a concern exists about the passage of water or moisture, any underlying substrate should be primed. (1)

Vermiduct^® should be protected from chemicals, which have an impact on plaster.
