Protect Roof Insulation with Breathable Membrane from DCT
the chalet - hunters hill, sydney
"The Chalet" is a very rare and distinctive example of an early prefabricated timber Swiss Cottage in Australia. Dating from 1855, the house was imported from Hambury, Germany, by Swiss émigré, Leonardo Etienne Bordier, and erected by indentured German tradesmen at Sab Hill, an early French settlement of Sydney. The house remains the only surviving cottage of four prefabricated cottages originally erected as part of Bordier's planned speculative development at Hunters Hill.
The property is also significant for its association with artist Nora Heysen, who lived and worked at The Chalet from 1954 until her death in 2003. Nora Heysen (1911-2003) is recognized as one of Australia's foremost female painters and was the first woman war artist in World War 2 and the first female recipient of the coveted Archibald Prize in 1938 at age 27.
Unfortunately years of neglect have taken their toll on this once beautiful home and its surrounding gardens. The current owners have undertaken the monumental task of restoring the Chalet to its former splendour.
Leading Sydney heritage slate roof specialists Westwood Roofing were contracted to restore the original Chalet pitched slate roof.
After the careful removal of the brittle slate tiles, bulk insulation has been installed to give this historic home a higher level of thermal insulation. Roofing insulation lowers energy usage and energy bills and reduces greenhouse gas emissions while improving the comfort and value of the home. Proctor Roofshield breathable membrane has been installed below the battens.
On average, a family of four produces 25 litres of water vapour per day. If an impermeable foil type sarking is incorrectly installed on the cold side of the insulation this can cause condensation, leading to structural damage and health problems for occupants due to mould spreading unnoticed within the building fabric.
The incorporation of Proctor Roofshield will "let the building breathe" allowing any moisture vapour in the roof cavity to vent, preserving the historic roof structure and keeping insulation dry and performing at its maximum.
Proctor Roofshield has been specified because of its high vapour permeability in a wide range of heritage projects around the globe ranging from Japanese temples, Toronto City Hall, Scottish whisky distilleries and Mawsons Hut in Antarctica.
