Quantum Specifications

Lower apex heights which can help to meet planning restrictions and reduce wasted roof space

More cost-effective solution than standing seam/secret fix systems

Rooflights can be integrated in the same manner as the metal roof sheets and span across the apex, improving light distribution

No ridge/hip ridge flashings eliminating the risk of water ingress and enhancing air tightness

Reductions in heating/cooling costs as a result of reduced roof volume

Greater roof area can be utilised for rooflights, or given over to rooftop solar PV arrays as there is no need to avoid a ridge apex

Often eliminates at least one run of secondary steelwork

Elimination of hips offers significant savings in steelwork, reduction in embodied carbon, materials, and reduction of programme

Can be used to eliminate parapet designs and the risk associated with internal boundary wall gutters

Maximum standard radius of 105 metres to facilitate a minimum end lap pitch of 4.0°design (2.5° after settlement and deflection). Greater radii may result in additional logistical issues

Roof design can help improve air tightness, reducing construction time and optimising overall costs
