Single Ply Roof Systems

Our single ply roofing systems are for lightweight, fast track and cost effective construction projects. The systems provide solutions that have the ability to withstand temperature extremes of -30°C when tested to EN 495-5 (as stated in the BBA certificate) and are able to support extensive green roofs  and BauderSOLAR photovoltaic arrays. Our single ply systems hold fire classification BROOF(t4) on defined permutations and verified by the BBA for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs.

Our single ply systems are CCPI verified. This means that the product information we provide delivers accuracy, clarity and reliable data to specifiers when selecting a Bauder solution. Please refer to the relevant system page for more information on the CCPI mark.

Single ply roofing systems are a popular choice for flat roofing solutions, particularly advantageous if the project has weight and load bearing considerations. The membranes have a life expectancy in excess of 35 years (Thermofol BBA certificate 06/4354) and in excess of 30 years (Thermoplan BBA certificate 04/4120) and are lightweight, typically 2-3kg per square metre. The speed of installation compared to traditional two layer RBM assemblies can make it a cost-effective method for waterproofing a flat roof.

We have two systems within our single ply portfolio – Thermofol PVC and Thermoplan FPO. Both are suitable for roofs of different shapes and sizes, come in a range of colours and are appropriate for extensive green roof landscaping. Within these two categories sit numerous options for a project. Your area technical manager will be able to tell you which is advisable for the needs of your project.

Why single ply?

Single ply is quick to install compared to more traditional 2 layer RBM alternatives and it is cost effective as a consequence. It’s durable and flexible, as set out in our BBA certification. Bauder is committed to reducing the impact our single ply options have on both society and the environment. All our single ply offerings come with a range of guarantees to meet the needs of the project and client (sample copies available upon request from Bauder). Bauder works hard to ensure all our products meet the latest criteria for various accreditations.

Installation and maintenance

The systems are installed using hot air welding techniques with mechanical fastenings or adhesive bonding to provide solutions that are durable, resilient to the natural elements and fire resistance. The quality and experience of the installing operative is paramount to ensuring a successful project. Bauder Approved Contractors are the only people trained and certified to install our products. They provide the necessary experience that our exceptional guarantee demands.

Green credentials

The mechanical fix option for either single ply system makes it possible to remove independent components. If only the membrane requires renewal, this element can be replaced without affecting the insulation and vapour barrier. Bauder PIR insulation is CFC and HCFC free with zero ODP and high thermal efficiency. Recycled PVC membranes are converted into other components and all our single ply production waste is recycled into the manufacturing process, enabling us to keep the use of raw materials to a minimum. We reduce water consumption by using automated rotation cooling systems in our manufacturing production, drastically reducing energy use and avoiding pollution of the environment.

Which system is right for my project?

Your local Bauder technical manager will help you to choose between our two single ply systems.

Thermofol PVC has a membrane with high tensile strength of 1100N/50mm when tested to EN 12310-2 (stated in our BBA certificate), containing polymers to ensure flexibility at -30°C (also stated in our BBA certificate). Its formulation is resistant to many chemicals, UV resistance and micro-organism attacks (for queries on resistance and compatibility consult Bauder Technical Department). Bauder employ a flame-free installation using hot air welding.

Thermoplan FPO membrane has a high tensile strength of 1200N/50mm when tested to EN 12310-2 (stated in our BBA certificate) and contains high-quality polymers to ensure it stays flexible at -45°C (also stated in our BBA certificate). The membrane has no inherent memory and will not shrink.

Both systems are halogen-free.

The Single Ply Roofing Association (SPRA) represents membrane manufacturers, associated component manufacturers and specialist sub contractors and aims to ensure the delivery of best value single ply roofing systems, through a quality assured partnership. By specifying products and specialist installation by SPRA Manufacturer, Associate and Contractor members you can be assured that all parties meet strict quality criteria. Compliance with these criteria and with the Code of Conduct is assessed at application, by annual audit and by random spot checks.
