Spectus uPVC Sash Windows
Supply Only, Delivered throughout the UK Mainland
The Spectus uPVC sliding sash windows carry all the beauty of a traditional design, coupled with all the benefits of modern materials that enable us to offer a cost effective, low maintenance window that doesn’t compromise on aesthetics.
From near-invisible joints, the elegance of the run-through sash horn to the curvy ovolo frame shape, these are just a handful of the many clever details that work together to create the most graceful and advanced sash window on the market.
With the increase of uPVC sliding sash windows being specified in premium developments, new design options and a bespoke colour-bonding service have been introduced, providing homeowners with a plethora of choice to create the perfect timber alternative solution that doesn’t break the bank.

Spectus Sash Window Features
AUTHENTIC JOINTS
Replace your standard corner joints with fully mechanical timber looking joints for an authentic finish that carefully disguises the uPVC aspects. Traditionally, a lot of time was spent handcrafting the original corner joints on timber sash windows and with our advanced machinery we can emulate these joints and get as close to the original as possible.
FULLY MECHANICAL JOINTS
The fully mechanical joints take uthenticity to another level because the 45° uPVC welds on the sash are replaced with 90° mechanical joints as found on traditional timber windows.
STANDARD 45° WELDED SASH
As standard, we’ll default to a mechanical jointed outer frame with a 45° welded sash. Fully welded is available upon request. The standard welding technique ensures that the corners are tightly bonded, creating a seamless and strong connection.
Other Features
Replace your standard corner joints with fully mechanical timber looking joints for an authentic finish that carefully disguises the uPVC aspects. Traditionally, a lot of time was spent handcrafting the original corner joints on timber sash windows and with our advanced machinery we can emulate these joints and get as close to the original as possible.
TRADITIONAL SASH HORNS
By removing the lip on the sash horn edge, a new refined sash horn can carry a oodgrain foiled end capthat run seamlessly with the shape of the horn. The sash horn utilises mechanical joints rather than welded to allow the horn to be a continuous part of the sash giving the window a more authentic overall look.
DEEP BOTTOM RAIL
Choose a deep bottom rail if you want your sliding sash windows to look as close to the original timber version as possible. The fully mechanical deep bottom rail convincingly mimics the bottom sash of timber windows from the Victorian era and looks great with run-through sash horns.
SLIM MIDRAIL
The styling details of our sash windows are now more rooted in history than ever before. The new 37mm slim midrail will by Spectus will position as one of the most authentic sash windows on the market ideal for period properties or homes in conservation areas. Available with run-through sash horns and in selected colours only.
ASTRAGAL BARS
Include a bar layout on your new sash windows for added character. Astragal bars are fixed onto the surface of the glass and are accompanied by back-to-back spacer bars inside the double-glazed unit to give the appearance of separate panes.
