Fire compliance on flat roofing systems

LISTEN HERE 🔊

Bauder has delivered roofing system solutions on Boston Road, London W7, a new residential development with numerous terraces and inset balconies. The site comprises 333 dwellings, of which 117 are of affordable tenure with the remaining 216 for private sale, and 1200m² of commercial space throughout three blocks.

The development required a waterproofing system that met the design requirements of the balconies and terraces whilst ensuring that it fully complied with the conditions under the Government’s Fire Safety: Approved Document B, as well as making sure the detailing and interfaces with other key trades could be achieved without compromising the system’s performance.

Bauder specified BauderGLAS insulation and Bauderflex bituminous waterproofing system. Bauderflex is a heavy duty and robust membrane which can withstand impact, tearing and is resistant to European climatic condition. This bitumen system is suited to new build and refurbishment applications and has up to 30 years life expectancy, as stated in BBA certificate 10/4744. A significant benefit is the torch-free and safe to torch installation on combustible details which reduces the risk for contractors and clients. Additionally, BauderGLAS insulation is manufactured from specially graded recycled glass (≥ 60%) and natural raw materials (which are available in abundant supply), has time-tested thermal performance, high compressive strength and most importantly, is also non-combustible, accompanying the Bauderflex waterproofing system to achieve a non-combustible build-up for this project.

By working closely with Bauder on the specific project requirements set down by their client, Higgins Partnerships were able to provide peace of mind that the products installed met the conditions placed on them by the client’s insurers, to fully comply with the strict stipulations under Fire Safety: Approved Document B and achieve BROOF(t4) certification.

Bauder is a leading international manufacturer of building construction materials providing clients with waterproofing membranes and insulation to make buildings watertight and thermally efficient. The extensive portfolio of Bauder waterproofing, green roofs and photovoltaics ensures the right solution is specified for each project from a single source.
