Qsystems: Roofing Cladding Systems - Design Benefits

Specification FlexibilitySPECIFICATION FLEXIBILITY

Quedron profiles can be supplied in a wide range of different materials, BBA certified coatings, BS and RAL colour options, meeting the most stringent life expectancy, structural and aesthetic demands.


THERMAL PERFORMANCE

All Qsystems shown are Building Regulations Approved Document L2 compliant. However, bespoke systems tailored to suit individual client requirements can be easily accommodated by using deeper variants of our standard spacer system (≤0.20W/m2K) or our newly launched revolutionary ‘mast’ system which gives the designer the potential to specify systems with ‘U’ values in excess of 0.16W/m2K. All Qsystems can be specified in the knowledge that they offer thermal performance longevity for the life of the building.

Acoustic PerformanceACOUSTIC PERFORMANCE

Excellent sound reduction performance; typically between 41 – 48dB (weighted S.R.I. Rw) - subject to system choice and product specification. Tests have shown that mineral fibre in direct contact with the outer sheet provides very effective damping performance. These acoustic benefits are significant when considering ‘noise pollution’ created by rain drumming. Reduction and damping performance of Quedron built up constructions are typically between 10 - 20dB better than the equivalent foam cored composite panel construction.

Fire ResistanceFIRE RESISTANCE

Products contained within Qsystems can be deemed non combustible in accordance with stringent British Standards. No reliance is made on test methods laid out by other independent or trade associated bodies to claim performance – commonly undertaken with foam cored composite panel.

Air PermiabilityAIR PERMEABILITY

When installed to manufacturer’s recommendations all Qsystems 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).

SustainabilitySUSTAINABILITY

Products contained within Qsystems are recyclable with no additional greenhouse gases and do not present the potential ecological impact presented by foam cored composite panels.

CostCOST

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

InstallationINSTALLATION

Logistically less demanding than composite panels due to their nestable nature,Quedron products take fewer lorries to deliver, use up far less site storage space and are easier and lighter to handle with less reliance on constant cranage. A choice of lining panel gauges allows the designer the option to specify the entire roof envelope ‘fully lined out’. This method of installation provides a dry working area beneath quicker than any composite panel installation times, thus allowing internal trades to commence work earlier and therefore, improve the building completion period.Due to their flexibility, Qsystem sheets accept larger steelwork tolerances than rigid composite panels, thus preventing possible air permeability, support bearing and fastener stress problems.
