More than 30 timber frame homes are benefiting from an external wall insulation system manufactured by Sto to help reduce heating costs and energy.

Constructed by Westridge Construction for Hyde New Homes, the crescent-shaped development consists of 32 homes ranging from two to four bedrooms. Located in Saltdean, East Sussex, the art-deco inspired properties are located between the south coast and the South Downs National Park.

The StoTherm Vario expanded polystyrene insulation (EPS) system, including Sto-Rotofix mini mechanical fixings, were specified and installed by Square 1 Architectural Solutions. Compared to rail systems, the Rotofix fixings require fewer components, the insulation boards can be installed more quickly, and Rotofix enables better levelling capabilities, as the fixings can easily be adjusted to provide a level surface prior to installing the rendered façade.

“We proposed Sto for this project as its Rotofix system was ideal for the timber frame construction,” explained Andrew Downer, Director at Square 1 Architectural Solutions.

“The undulation which can occur in timber-framed walls makes it more difficult to fix external wall insulation. The Rotofix mini fixings have a unique spiral design which overcomes these challenges and results in a higher quality façade finish. The system also enabled us to create a cavity behind the insulation board allowing any excess moisture to drain and provide the wall structure with a secondary line of defence from the effects of the weather.”

The StoTherm Vario system was finished with StoSilco K silicone resin render, in white, to provide high water repellence and resistance to dirt build-up, as well as the growth of algae and fungus. To enable the render to be applied around the circular windows which feature throughout each property, a curved bead was also supplied by Sto to help form the neat render finish.

Andrew continued: “It was vital to use a high-quality render like StoSilco to provide both a protective and decorative finish. The homes are located just a stone’s throw away from the sea and every building is completely white. The StoSilco render will ensure the homes will maintain their clean, bright appearance for many years to come.”

Available for sale, rent and shared ownership, the homes are collectively known as Seaview Meadows. The development won the silver prize for Best Interior Design at the WhatHouse? Awards and has been praised for its innovative design and enviable location.
