Historic choice
Quantal’s aluminium roofing system has been selected by Sash UK for a 190m2 conservatory installation at a Grade II listed stately home.
Sash was appointed by Bijou Wedding Venues to create a bespoke conservatory at Botleys Mansion, Surrey, a paladin style mansion house which was originally built in 1765.
In addition to sheer scale, Sash had to overcome a number of technical challenges caused by the design and structure of existing buildings.
Colin Poole, conservatory director, Sash UK said: “It’s a big project and anything on that scale raises challenges, especially considering the age of the building.
“The design and long bi-fold doors running along the lengths of the building raised particular challenges because it meant that a number of our portals had to stop short of the ground and be designed to slot directly into RSJs.
“This in itself meant that we had to do extensive and structural calculations to ensure that the weight and forces generated by the roof didn’t push the existing buildings out.
“The strength of the Quantal system is that not only does it have the structural integrity to deliver larger and more complex projects but it can also be adapted with comparative ease to create a bespoke solution.”
The new conservatory is being used by the luxury wedding venue as a reception room.
The Quantal system features a number of innovations among them: the patented RotaFit twist-and-lock allowing Quantal’s new hip bars to be fitted without the need for nuts or bolts; a Jack Rafter system, delivering improved weather tightness through precise factory-fabricated sections, speeding up installation time by creating positive location for all fixings; and Twin fast, a simple fixing system allows installers to slide glazing bars into place while Twinfast’s in built spacer to create the perfect glazing plane.
It also features: a structural box gutter eaves beam that supports pitches of up to 40 degrees on gables and lean-tos without the need for mechanical fixings; UniRidge, designed to address a range of design problems and which can be used on pitches between 22 and 30 degrees, accepting 24mm DGSU; and a Valley Detail, designed to speed up glazing and increases design flexibility through a new glazing stop that eliminates glazing slip.
