Classic range by Mumford & Wood
In May 2016, Mumford & Wood announced the addition of a new timber window and door range designed especially for replacement projects in period buildings, which runs alongside the established Conservation™ range.
The appeal of the Classic™ range lies in the fact that visually it is in keeping with the period aesthetics, an important requirement for window replacement and upgrade in heritage projects and those in conservation areas where planning restrictions may apply. In part, this is achieved by having an alternative slim panel glazing system that effectively reduces sight lines and reflection.
The Classic™ range is made-to-order, available with a choice of profiles. The double glazed products feature individual 12-14 mm slim profile units with true bars and a traditional external putty-faced finish. In addition to standard annealed float glass, there is the opportunity to achieve the authentic natural appearance of hand-blown glass, with reduced reflection, by choosing either Victorian sheet or Crown glass.
These high performance windows and doors feature Krypton gas-filled panels that achieve a 1.9 W/m²K overall frame U-value, and a 1.5 W/m²K centre pane U-value, with a five-year warranty on the double glazed unit.
Along with Mumford & Wood’s other products, the Classic™ range is made from FSC-certificated Siberian Larch. This is a slow-growing and dense timber which is engineered for maximum strength and robustness.
Independent research identifies that these windows, which are made to the standards of the British Woodworking Federation Wood Window Alliance scheme, have a life cycle expectancy of up to 65 years and more.
According to Mumford & Wood, ‘our slim pane Classic will meet the aesthetic requirements of conservation and planning officers while at the same time improving the thermal, acoustic and sustainability performance of some of Britain’s most loved buildings.’
The Classic™ range includes the following products:
- Box sash windows.
- Spring sash windows.
- Tilt and slide sash windows.
- Casement windows.
- French casement windows.
- French and single doors.
- Balcony doors.
- Bi-folding doors.
- Entrance doors.
