Press release / Slenderglaze breaks through period property double glazing barrier
Press release issued for Sash Consultancy, a double glazing for period property specialist business
Traditional sash windows with double glazing ARE now an option for owners and renovators of period and listed property, thanks to the Sash Window Consultancy
The specialist firm with extensive experience in replacing and repairing traditional wooden windows has pioneered a double glazed sash window that found favour with local authority conservation officers.
The handcrafted Slenderglaze windows developed by Somerset-based Sash Window Consultancy have been granted listed building consent, where the existing windows were deemed inappropriate.
“Owners of period and listed properties are now able to enjoy improved energy efficiency and noise reduction, as the Slenderglaze window offers these benefits without compromising on the historical character and value of the property” commented Neil Jackson of the Sash Window Consultancy.
In place of an aluminum spacer bar, the Slenderglaze sash window features warm edge polymer spacer bar technology, which enables the double glazed unit to fit into traditionally constructed window rebates, without the need for unsightly timber glazing beads and stuck-on glazing bars.
Before the arrival of this window technology, the upgrading of period properties with double glazing was deemed undesirable owing to the plastic, aluminum and unsuitable timber window frame options available. While timber provides the material of choice, until now, the accompanying glazing did not fulfill the planning criteria for listed properties or those in conservation areas.
“We’re already working with conservation architects and builders renovating period properties, who’ve been genuinely amazed by this product. The windows replicate every detail of the original single glazed sash window, including real glazing bars; and offer all the benefits associated with modern double glazing. We’ve not seen another double glazed sealed sash window that provides a more thermally efficient and aesthetically pleasing option.
“This product has been recognised as an acceptable upgrade option by the conservation planners we’ve worked with and we’re hoping this recognition becomes much more widespread amongst those involved with period and listed properties.
“It’s no longer realistic to expect people who live in old buildings not to optimise their insulation. This product provides the alternative to turning up the heating and allows people to live more comfortably in older properties.”
The Slenderglaze warm edge spacer technology consists of a polymeric tape that has a desiccant embedded in its structure. It is physically smaller than a contemporary spacer bar and more attractive. It allows the perimeter margin to be kept to a minimum so it can be glazed into traditional glazing rebates and glazing bars.
Even to the trained eye, these products are difficult to detect as being new, owing to the distance between the two panes of glass. This has been achieved by filling the cavity with the appropriate inert gas. The added advantage of this design is the thermal efficiency achieved: cold spots are eliminated and so too is the resulting condensation around the perimeter of the inner pane.
