Seamless Extension Achieved with Onduline ISOLINE LOW LINE at Chelmsford Barn House

A beautifully presented barn house in Chelmsford has undergone a sympathetic extension, a project expertly handled by Melbid Construction with architectural design by Ward-Booth Architects. A key challenge in this build was seamlessly integrating the new roof with the existing structure, particularly concerning the roof pitch. While the homeowner desired to match the existing roof tiles for aesthetic harmony, the planned extension featured a pitch lower than the minimum recommendation of the tile manufacturer. This is where Onduline's ISOLINE LOW LINE system proved to be the ideal solution, ensuring a watertight and visually consistent finish.

Low pitched roof with matching tiles

The primary concern for the extension was achieving reliable waterproofing on a lower pitch. Traditional roofing methods and even the chosen roof tiles alone would have presented a risk of water ingress. To overcome this technical hurdle without compromising the desired aesthetic, the project team specified Onduline's ISOLINE LOW LINE. This innovative sub-roof system is specifically designed for low-pitch applications, providing a robust and continuous waterproofing layer beneath the decorative roof covering.

Primary waterproofing

ISOLINE LOW LINE acts as a defense against the elements, effectively channelling any water that might penetrate the tiled layer safely down to the eaves. Its lightweight and easy-to-install nature made it a practical choice for Melbid Construction, ensuring an efficient and reliable installation process.

ISOLINE LOW LINE becomes the primary waterproofing element of the roof.

Helping the homeowner achieve the unified roofline

Crucially, the use of ISOLINE LOW LINE allowed the homeowner to achieve their vision of a unified roofline. By providing a watertight base, the system enabled the installation of the same roof tiles used on the original barn house. This meticulous attention to detail has resulted in an extension that appears as a natural and integral part of the existing property, with no visual disruption caused by differing roof materials or pitches. The seamless transition between old and new is a testament to the thoughtful design and the capabilities of the chosen roofing system.

Optimal ventilation

Further enhancing the roof's performance and longevity, the project also incorporated ONDUTISS AIR 160. This breathable underlay works in conjunction with the ISOLINE LOW LINE system to provide optimal ventilation within the roof structure. By allowing moisture vapor to escape, ONDUTISS AIR 160 helps to prevent condensation build-up, protecting the underlying timber structure and contributing to the overall health and lifespan of the roof.

The Chelmsford Barn house extension stands as a prime example of how innovative roofing solutions can overcome complex design challenges without sacrificing aesthetic appeal. By specifying Onduline's ISOLINE LOW LINE, Ward-Booth Architects and Melbid Construction successfully navigated the limitations of the low roof pitch, delivering a watertight, durable, and visually harmonious extension that perfectly complements the original character of the property. The homeowner now enjoys an expanded living space with a roof that not only performs exceptionally but also seamlessly blends with the existing architectural style.
