Classic Collection
The Classic Collection can be a valuable addition to a prestigious modern development, setting your properties apart from the mass produced budget houses.
Elegant proportions
Your sliding sash window will be perfectly balanced aesthetically. If you choose to have Georgian bars the panes will be evenly sized.
Frame & Design
Ovolo sashes and Georgian bars internally and externally recreate the look with modern styling.
Continuous Horn Detail
Traditional sash windows incorporated a decorative feature to the underside of the top sash, referred to as a decorative horn. We offer a plant on horn for the Classic collection.
Authentic Collection
The Authentic Collection is more in keeping with the traditional style of sash windows and can be a valuable asset to your property.
Elegant proportions
Your sliding sash window will be perfectly balanced aesthetically. If you choose to have Georgian bars the panes will be evenly sized.
Frame & Design
Chamfered putty line sash detailing externally for a more traditional appearance.and internal and external Georgian bars.
Continuous Horn Detail
Traditional sash windows incorporated a decorative feature to the underside of the top sash, referred to as a decorative horn. We offer a plant on horn for the Authentic collection.
Vintage Collection
Superior Torso spring balances allow sashes to glide smoothly (tested to 50,000 opening cycles). In addition The Georgian panes are equalised in the frame, which means your windows will look perfectly balanced.
Traditional Features
We have reproduced the staff bead frame detail whilst the sashes, and external Georgian bars have the putty line edging to recreate the traditional style.
Continuous Horn Detail
Most window manufacturers try to recreate this feature through the addition of a 'bolt on' shaped pvc part to the bottom of the welded top sash. The Vintage Collection does not do this, instead the jambs of the upper sash are extended and precisely milled to form a continuous horned effect. This is far more pleasing to conservation officers and to those who appreciate traditional styling.
Sash Styles
The Classic, Authentic and Vintage sash windows collections can be manufactured in just about any style or shape you require whether it be Centre Bar, Asymmetric, Georgian or Half Georgian. Please ask one our representatives if the design you require is not shown.
The Vintage Collection is available in either a standard PVC-U finish or subtle white woodgrain which gives the appearance of a freshly painted wooden sash window. In addition the lower rails of both upper and lower sashes give a butt jointed appearance rather than the diagonal weld line associated with PVC-U windows.
