Single Ply roofing systems
Single ply membranes are ideal for lightweight, fast track and cost-effective roofing construction projects, and are able to support extensive green roofs and solar PV.
Specifying a single ply membrane system
Strong and flexible single ply membranes composed predominantly of synthetic polymer involving polyvinyl chloride (PVC) and flexible polyolefin (FPO). Suitable for new build and refurbishment projects. Single ply roofing systems are advantageous if the project has load-bearing considerations. The membranes are durable and resistant to European climate considerations, yet incredibly lightweight, typically 2-3kg/m2.
We have adopted the Code for Construction Product Information (CCPI) across our roofing portfolio to have information assessed for accuracy and clarity to ensure specifiers can rely on the information when selecting a Bauder single ply solution.

Single ply roof systems
There are two types of single ply membranes for flat roof systems within our portfolio, either PVC or FPO polymer plastics, all with adhered, mechanically fastened, or loose laid installation options.
Our Profiled PIR Infill Overlay System uses either of the membrane types as the waterproofing atop the insulation boards.

Six steps is all it takes
Brief and consultation
You give us your remit either at your office or on-site. We will discuss the roofing project, your preferred system application, your budget and how the programme of work can be formulated.
Roof element proposal
Together we can determine which roofing system and specific build up will be optimal for each individual roof area on your project given the construction type, level of access and required performance.
Specification and detail design
You will receive the Bauder specification package that answers your brief and meets the needs of the building. As a specialist designer for our solutions, we work with the Principal Designer to include relevant standard detail drawings and other technical calculations.
Contractor selection
The Bauder approved contractors best placed to deliver your new roof will competitively price and tender for your project. Our national network of contractors undergo a rigorous selection process and their installers are trained specifically in the application of our systems, so you are ensured an expert installation.
Installation of the roofing solution
Once the Bauder approved contractor has been appointed, a pre-contract meeting will make sure that the project delivery is well coordinated. The works are closely monitored by Bauder site technicians with regular inspections and live time reports to ensure the quality and waterproof integrity of the roof.
Sign off and guarantee
A full final inspection is completed by our site technician team before the guarantee is issued.
Bauder’s service doesn’t just stop once the roof installation has been completed, we provide industry-leading guarantees on our products that are installed by our national network of approved contractors.
