Single ply systems

Our single ply roofing systems are ideal for lightweight, fast track and cost effective construction projects. The systems provide solutions that are durable, resistant to the natural elements and are able to support extensive green roofs and BauderSOLAR photovoltaic arrays.  All our single ply systems hold fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs.

Single ply roofing systems are one of the most popular of flat roofing materials, particularly advantageous if the project has weight and load bearing considerations. The membrane is durable and resistant to European climate conditions, tears and punctures, yet incredibly lightweight, typically 2-3kg per square metre. The speed of installation makes it a cost-effective method.

We have two systems within our single ply portfolio – Thermofol PVC and Thermoplan T FPO. Both are suitable for roofs of all 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.

  • Thermofol PVC

    Project: New build or refurbishment
    Construction: Warm, cold, inverted
    Upgrades: Green roofs and PV

  • Thermoplan FPO

    Project: New build or refurbishment
    Construction: Warm, cold, inverted
    Upgrades: Green roofs and PV

Why Single Ply?

Single Ply is quick to install and cost effective. It’s durable and flexible and 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 valuable guarantee. Bauder works hard to ensure all our products meet the latest criteria for various accreditations.

Installation

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 give excellent fire resistance. The quality and experience of the installing operative is paramount to ensuring a successful project. Bauder Approved Contractors are the only people fully 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 extremely 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, containing polymers to ensure flexibility at -30°C. Its formulation is resistant to chemicals and micro-organism attacks. Bauder employ a flame-free installation using hot air welding.
  • Thermoplan FPO membrane has a high tensile strength of 1200N/50mm and contains high-quality polymers to ensure it stays flexible at -45°C. The membrane has no inherent memory and will not shrink.
Both systems are halogen-free.
