Composite Windows/Doors

Designed and tested to exceed all contemporary standards, the Kingston system offers a comprehensive range of purpose made factory finished timber/aluminium composite windows, doors and associated products at affordable prices. The system comprises both outward and inward opening windows and doors, suited fixed lights, panels, louvres and operating mechanisms which are all custom manufactured to size, shape and finish offering designers the flexibility to create the facade of their choice.

An extensive range of opening styles, glazing configurations and ironmongery options are produced to meet virtually any performance requirement, especially in matters of thermal insulation, acoustic attenuation, solar control, safety and security. This means that Kingston Window Systems is the solution for commercial and residential projects, whether they are new build or refurbishment schemes. Our composite windows have a wood/aluminium construction. Elegant aluminium profiles on the outside and warm inviting timber on the inside combine the benefits of both materials to provide a durable low maintenance exterior with the comfort, visual appeal and performance benefits of superior quality internal joinery.

Quality as standard

Kingston system composite windows and doors are available in a full range of opening styles, including the latest top hung and side hung reversible mechanisms.

Supplied fully factory finished and glazed to specification, they come complete with an extensive choice of ironmongery options for safe, secure and trouble free operation.

The concealed action of the projecting top hung reversible mechanism of Kingston windows allows easy, yet safe cleaning and re-glazing from inside. Strong and well balanced, the entire 'reversing' action takes place outside the window frame so there is no fouling of curtains, blinds or internal fitments. The easy glide hinges incorporate integral safety restrictors in both the opening and fully reversed cleaning positions whilst the concealed multi-point locking espagnolette provides a secure night vent facility.



Precision machining and assembly, together with the use of multipoint espagnolette locking, superior weatherstripping materials and sealants, ensures our indows perform to the very highest classification tegories of EN1026, EN1027 and EN12211 for Air Permeability, Watertightness and Wind Resistance.


Kingston windows and doors are designed to combat risks to safety as well as to provide convenience and ease of operation. Windows are fitted with a variety of opening and cleaning position safety restrictors, locking devices, antislam friction stays and safety glass to offer complete peace of mind to the user.


Robust construction, combined with concealed multipoint espagnolette locking and high performance security devices, means the Kingston system offers exceptional levels of security. For enhanced security performance requirements Kingston windows and doors can be supplied in accordance with BS7950/PAS24 Secured by Design standards.

Solar control blind systems

The Kingston system can be specified with double or triple glazed sealed units which incorporate the latest generation of solar control glass from Europe's leading manufacturers. Kingston coupled sash windows and doors can also be supplied with integral blind systems for additional solar control and anti glare purposes.

Thermal insulation

Exceptional standards of thermal insulation with the use of high grade timber with a very low thermal transmittance value, greatly reducing heat loss through frame members. Double or triple glazed sealed units combined with the latest low emissivity coatings and the use of insulated spacers and gas filling, means Kingston products can be supplied with whole window U-values of less than 1 .0W/m2K.

Acoustic attenuation

Careful attention to design and detailing means that all Kingston windows offer a high standard of noise insulation. Double glazed windows can typically provide a sound reduction of up to 44dB(Rw) with the use of laminated glass. For higher performance, Kingston coupled sash and double windows offer even higher performance.
