Kalzip® Deck Roof

Deck roof systems


Kalzip deck roof systems are engineered to deliver effective roof designs with integrated insulation. Comprising components specifically designed to work together, these systems provide reliable thermal solutions, contributing to enhanced energy efficiency and longevity. The use of durable materials and precise design offers robust protection against moisture and environmental factors. As per the Kalzip BBA certificate reference 98-3481 Deck Roof System Product sheet 2: Issue 2

The advantages of the Kalzip deck roof:

  • No rear ventilation required as with a cold roof construction
  • Low dead weight of the entire construction
  • Applicable to all substructures due to system variations guidelines
  • Ideal for flat pitched roofs from 1.5°
  • Fast, largely weather-independent installation
  • Low U Values can be achieved utilizing various insulation products
  • Penetration-free installation of solar modules & fall protection

The perfect roof structure for
high thermal insulation and energy efficiency

The advantages of a Deck roof:

  • No specialist lightning protection requirements, as the aluminium standing seam roof serves as a natural component of the air-termination network.

  • Steelwork frames etc of any kind must be checked separately.

  • Secret fix roof system, therefore, no weak points due to exposed fasteners

  • Achieves fire classification BROOF t4 as per BRE Report P125966-1000 Issue 2

  • Durable and sustainable
    thanks to the use of recycled aluminium alloys

  • Various customised geometries/shapes can be achieved, thanks to XT free-form Kalzip profiles

Applications for deck roof superstructures:

  • Industrial applications: Kalzip deck roofs are often used in industrial buildings such as factories, warehouses and production facilities to provide effective thermal insulation.
  • Commercial applications: The roof system is also suitable for commercial applications such as office buildings, shopping centres and hotels to reduce energy consumption and create a pleasant indoor climate.
  • Public buildings: The roof system can also be used on public buildings such as schools, hospitals and government buildings to reduce energy consumption and create a comfortable indoor climate.
  • Sports and leisure facilities: It is also popular in sports and leisure facilities such as swimming pools, gyms and sports centres to improve the environmental balance and energy consumption.
