Description

The Britframe system is a structural steel frame that converts flat roofs to pitched roofs. Our Britframe system has been recommended and specified on a fundamental number of projects including schools, MOD, social housing, and many more.


Britmet is committed to supplying the marketplace with a bespoke refurbishment/new build system package, incorporating a lightweight steel framing system, primarily designed to create a roof pitch. The Britframe system offers a permanent solution to failed flat roofs and can be used to construct a variety of pitched or curved roof structures. They can accommodate both the simplest gable end designs to the most complicated ridges, hips, valleys, soffit fascia and overhang requirements.


A range of systems is available that can be individually designed and tailored to suit the existing roof's specific structural and design requirements, offering a permanent solution to failed flat roofs. The lightweight structural metal frame system has an excellent strength to weight ratio, as Britframe over-roof conversion systems are constructed using a bespoke lightweight steel framing system, primarily designed to create a roof pitch but can support both modern and traditional over-cladding systems to achieve the required aesthetics.


Britframe uses pre-manufactured lightweight metal trusses designed to span from load-bearing walls to load-bearing walls and manufactured to suit all roof scopes, sizes and profiles.


Features and Benefits

By providing a cost-effective, lightweight solution to create a pitched or curved roof option that not only enhances the overall aesthetic of a tired and troublesome flat roof but also provides a range of features and benefits:

  • Protection of the existing flat roof by complementing the Britframe solution with a durable and cost-effective new roof covering.
  • Elimination of continual costs of repair and/or replacement of the existing flat roof as well as all of the associated disruption this can cause to occupants and building users/owners.
  • Opportunity to greatly enhance the thermal performance of the existing. Building, reducing heating costs and saving energy. Roofs that were installed before 1990 usually have little to no effective insulation.
  • Extended building life and excellent pack-back on the full life-cycle costing (when compared to the costs of repair and refurbishment of existing flat roofs.)
  • Minimum disruption to occupants and elimination of continued leaks associated with existing flat roofs.
  • Full audited design and installation service supported with a full independent insurance-backed warranty on both products and installation.
  • Enhanced appearance, making properties more attractive for visitors/users/tenants
