Roof Decking Systems

SPECIFICATION FLEXIBILITY

Qdeck sections can be supplied in a wide range of
different materials, coatings and colour options to meet life expectancy, structural and aesthetic demands.
Qdeck sections can be used to support single ply membrane or profiled roof systems. Very low pitch applications are easily achieved. ‘Standing seam’ appearance single ply membrane
systems are available. Qdeck sections allow a multitude of design options such as convex, concave and even tapered curve elevations.

STRUCTURAL PERFORMANCE

Structural deck sections offer long span capability thus omitting the secondary support content. Lightweight construction and fewer supports helps reduce the load on the primary structure thus allowing lighter design and reduced costs. Qdeck sheets may be used to laterally restrain the top flange of the secondary support structure. Qdeck sections can be used within diaphragm roof design to eliminate in-plane roof bracing.

THERMAL PERFORMANCE

All Qdeck systems shown are Building Regulations Approved Document L2 compliant.
Bespoke ‘U’ values can be easily accommodated with simple modification.

ACOUSTIC PERFORMANCE

Excellent sound reduction and damping performance can be achieved with our solid Qdeck systems.
Qdeck sections are available perforated offering good levels of sound absorption and reduced reverberation.

FIRE RESISTANCE

All Qdeck sections achieve a Class 1 fire rating in accordance with BS476: Part 7 and meet Class 0
requirements as laid out within current Building Regulations.

AIR PERMEABILITY

If installed to manufacturer’s recommendations all Qdeck systems can easily achieve and significantly
improve upon the 10m3/hr/m2 @ 50 Pa maximum air leakage stipulation as laid out within Building Regulations Approved Document L2 (2006).

SUSTAINABILITY

Qdeck sections are recyclable with no additional greenhouse gases and do not present potential ecological impact.

COST

Qdeck products are economic, have good lifetime performance and do not present high disposal costs at the end of their life..

INSTALLATION

Logistically less demanding than composite deck panels due to the nestable nature of profiled single skin, Qdeck products take up far less site storage space and are easier and lighter to handle. Qdeck can be secured to provide a dry working area beneath quicker than composite deck panel installation times. This fastrack installation allows internal trades to commence work earlier and therefore can improve building completion times. Due to their flexibility, Qdeck sections accept larger steelwork tolerances than rigid composite deck panels, thus preventing possible side lap air sealing, end lap bearing and fastener stress problems.
