Kalzip flat roofing systems Kalzip flat roofing systems
Proven benefits, new opportunities Architects, designers and specifiers have long recognised the creative possibilities afforded by the Kalzip standing seam roofing system, with millions of square metres now installed on roofs of every shape and size. The success of any roof is measured by its long term performance and this is just one area in which Kalzip offers substantially improved performance – and whole life cost – compared with traditional flat roof materials. Inherently strong and watertight With its ease of installation, inherent water-tightness, durability and 40 year guarantee, Kalzip makes sense from a financial as well as aesthetic point of view. Kalzip is renowned for its visual impact and performance on numerous landmark and prestigious buildings around the world, and for its ability to accommodate the most complex of geometries, both angular and organic in form. As an aluminium product, Kalzip combines strength with lightness. It is durable, corrosion-resistant and essentially maintenance-free. In short, it offers the best of both worlds: aesthetic appeal and ultimate practicality. The design of the Kalzip system builds on these qualities, enabling quick and easy installation with techniques that maintain the robustness of the material. Kalzip’s weather-tightness is based on its mechanical properties as opposed to manual finishing or the application of sealants. As an aluminium product it is also far more resistant to damage (e.g. punctures, tears) than other materials and its properties will not be compromised by temperature cycling. It is also a system as well suited to flat/low pitch roofs as it is to the more elaborate curved and/or tapered roofs for which it has earned its outstanding reputation. Kalzip is a proven solution offering complete versatility across every kind of roofing application and is available in a multitude of standard Kalzip configurations to cater for all designs and the most exacting performance requirements.

Cost-effective solution for flat/low pitched roofs The durability, ease of installation and maintenance-free nature of Kalzip also means it offers a cost-effective alternative to single ply membrane. In fact, a whole life comparison (WLC) report published by the Building Research Establishment (BRE) concluded that: “… in the longer term, the predicted cumulative life cycle costs show that the Kalzip liner roof actually provides the most economical option …” The low operational cost associated with Kalzip is one of its key advantages. Where other roof types tend to require regular cleaning, maintenance and overhaul of failed areas, a Kalzip roof is essentially maintenance-free, Agrément Certificate No 98/3481 states that, depending on the environment, Kalzip “will have a minimum service life of 40 years” and this is reflected in the Kalzip XL Guarantee, a forty year performance guarantee that covers the full system build from the outer sheet through to the internal liner. Fast, quality-assured installation Installation of Kalzip roofing is carried out to a high level of predetermined standard details by fully trained and approved members of the Teamkal installer network. Indeed, the Agrément Certificate specifically links site working practices with system details, providing further assurances of the highest standard of installation. The mechanical nature of the fix, combined with a system of integrated, prefabricated components and accessories, minimises installation time and ensures that the building is watertight far sooner than would be possible using alternative roofing methods. Another important benefit is Kalzip’s ability to be installed in virtually all conditions, substantially reducing the risk of delays due to adverse weather. Excellent thermal and acoustic insulation Once installed, a Kalzip roof provides excellent performance in terms of minimising heat transfer and sound levels. The use of aluminium helps to reduce heat transfer and this property can be enhanced with surface treatments, enabling energy flow through the roof to be cut from 340 to 50 W/m 2 . The qualities of heat reflection in summer and heat retention in winter enable energy saving and associated cost reduction. Kalzip also offers good acoustic performance, with tests demonstrating the ability to reduce noise levels by as much as 53dB (typically 38-40dB). Insulants or acoustic mat can be incorporated to further enhance this performance if required.
