    Cold Roof Solutions for Specific Designs and Needs

    What is a Cold Roof?

    In cold roof construction, the waterproof membrane is applied directly to the structural decking. This type of waterproofing requires adequate ventilation to be facilitated between the deck and the insulation layer to prevent moisture vapour rising upwards. Poor ventilation could be the cause of interstitial condensation in the roof structure.

    The popularity of cold roof systems in the UK is on the decline, with Scottish Building Regulations not allowing cold roof design at all. Most specifiers therefore are encouraged to choose warm roof systems instead however cold roof systems have their advantages and place within flat roof construction.

    Pros and Cons of a Cold Roof System

    Pros

    Makes use of otherwise unutilised space

    Doesn’t affect the profile of the building

    Cons

    Adequate cross ventilation is difficult to achieve

    Thermal bridging issues

    Cross ventilation over a 5mm span is not recommended

    Difficult to install and maintain an effective AVCL below the insulation

    Product Suitability for Cold Roof System

    By successfully combining the best characteristics of thermoplastics and elastomers, IKO Polymeric have manufactured roof coverings that offer optimum performance and easy installation. Our IKO Spectraplan Single Ply Roofing Membrane and our IKO Armourplan PVC Roofing membrane – available in two colours – are versatile roof membranes, suitable for specialist projects as well as a range of standard roofing applications. Both are simple and quick to install and can be mechanically fastened, adhered or loose laid and then ballasted.

    Our range of high quality insulation, air and vapour control layers and ancillaries, are also designed to create low weight, holistic roof systems for better protection and durability. For bespoke projects that may require specialist sizing or detailing, we also offer a pre-fabrication service.
