They are manufactured from PVCu profiles and bring all the benefits of low maintenance, security, comfort, weather resistance, as well as being fully recyclable.
These traditional style products are crafted using environmentally friendly lead free PVCu profiles, and can be specified with energy efficient double- or triple-glazed sealed units for optimum energy performance.
Our flush windows have achieved an A +5 energy rating, making them the perfect choice for the energy conscious consumer.
Our standard PVCu windows are A energy rated, and achieve that solely on heat retention without bringing in solar gain, with A+ ratings available.
SCI has been doing this for over 30 years. With around 10,000 satisfied replacement window and door customers, SCI has thrived on quality, innovation and customer care. Our customers appreciate the no pressure, no hassle approach and commitment to service – long after the installation has been completed.

We supply a full range of soft coat low emission glass with laminated and toughened glass where required, to provide safety and security where needed. Once an optional extra, low-E glass is now fitted as standard, in compliance with current Building Regulations.
Low-E glass is a fantastic way to reduce energy bills, by providing excellent thermal insulation with U values down to 1.4 W/m2K. It allows high light and solar heat transmittance for the best use of natural lighting and beneficial solar heat gain.
It provides colour neutrality in both reflection and transmission, giving windows a natural appearance, whilst maintaining a pure reflection. Unlike the old hard coat glass which had a tint and made your curtains look dirty.
Lead is used to add style, character and authenticity to your windows, with the option of using a blackened technique to provide a darkened, aged feel to the structure.
Soldered joints are an optional extra that also gives you a genuine antique look.
Lead is available in 4mm, 6mm, 9mm, and the traditional 12mm widths.
Laminated glass is created by sandwiching a thin vinyl layer, typically of Polyvinyl Butyral (PVB), between two pieces of glass using heat and pressure. It is primarily used for its safety, security and sound reduction benefits. Its toughness and resilience makes this type of glass an excellent safety glazing option.
PVB films are able to block 99% of ultraviolet radiation and prevents furniture and other indoor items from discolouring due to irradiation.
With 6.4mm glass thickness compared to the standard 4mm, laminated glass can also add sound insulation to properties, which may be particularly beneficial when living on busy streets where noise pollution is a problem.
Integral bars add great character to your property, yet still retain the ease of cleaning and maintenance to your windows, as the feature bars sit inside the double glazed sealed units.
Available at 18mm or 25mm widths in white, silver aluminium, or any wood grain finish we offer with our PVCu range.
Astragal Georgian Bars
Astragal Georgian bars are a new development to the PVCu market, and resonate with traditional Georgian bars on timber windows windows being fitted to the outside surface of the glass so you can feel them.
We offer two different bars:
- Ovolo: Designed with a rounded profile to suit that Ovolo frame
- Bevelled: Designed to replicate the style of traditional time frames, with a slim, angular bevelled sash bar.
Choose from our range of colour or bevelled fanlights, acid etched glass or bespoke stained glass added to your windows to enhance their aesthetic appeal.
Our hand-crafted glass range is a combination of colour, lead and glass. Whether applied to a new project, or installed as replacement glazing, they can be using in windows, doors, side panels and conservatories. Our exclusive designs are a valuable addition to any interior design.
We offer a bespoke range of stained glass, utilising a handmade factory process to produce a wide range of finishes to suit your requirements.
Acid Etched Glass
Etched glass gives a frosted, glazed look with a high level of detail and sophistication. The stencils, created using C.A.D. technology, offer an even glass frosting using modern blasting technology.
Our bevelled range comprises bespoke patterns with combinations of individual sections of bevelled glass.
Each piece is bonded to the glass surface, providing a stunning three dimensional effect that can, if required, by combined with any colour film.
Our windows have been tested to meet the exacting PAS 24: 2012 standard. They can be specified with six point locking & twin bi-directional cams, which prevent jemmying.
Our standard shootbolt locking system and optional anti-intrusion hinge bolts aid your security to ensure both sides of the window are equally protected from attack. These engage into strong metal to prevent the window being forced outward so you can rest safe in the knowledge that your home is well protected and far more secure than with older style locking and handle gear.
