GAMMAPAC panels are multipurpose panels designed to meet a wide
range of applications. They are suitable for all coverings normally
used with access flooring.
Composition:
The GAMMAPAC panel is made up as follows:
- A high density resin bonded core, standard thickness 30 or 38
mm.
- A bottom plate of 0.5 mm thick galvanized steel.
- A surface covering of desired quality and colour.
- A PVC surrond, heat bonded to the edge of the core.
Coverings:
The GAMMAPAC panel is available with the following coverings:
- High pressure laminate.
- Vinyl.
- Linoleum.
- Textile covering.
The GAMMAPAC panel is also available without covering.
Dimensions:
Standard size : 600 x 600 mm
Options:
Top plate of 0.5 mm thick galvanized steel (only available for panels without covering).
Top plate of 0.2 mm thick aluminium.
Top foil of 0.1 mm thick aluminium.
Special sizes. Top varnished.
Fire classification:
The GAMMAPAC panel is classified M1 ( SNPE report n° 7270/96 ).
Electrical Resistance:
It varies from 5x106 to 2x1012 Ohms, according
to the type of the covering and the composition (French Standard
NFP 62001, part C).
Acoustic:
The acoustic insulation measured between 2 adjacent rooms, separated
by a densely insulated partition, varies from 38 to 44 dBA , depending
on the thickness of the panel, the stringers and the covering.
