UPVC stands for Unplasticised Poly Vinyl Chloride. Also sometimes known as vinyl, it is a material that is rigid, long lasting, durable and low maintenance. UPVC double glazed and triple glazed windows offer high energy efficiency and are designed to be strong, robust and secure. We can supply and install a range of upvc window styles to compliment all properties from Woodgrain to White, Anthracite Grey to Irish Oak.

Maintenance Free

UPVC windows will never rust, rot, peel, are fully recyclable and lead free. Our windows are supplied with easy clean hinges that only need an occasional wipe down with warm soapy water.

Quiet and Warm

Our windows are all made to measure and A+ rated as standard. The window frame and sash are multi chambered to reflect heat back into the property, whilst also preventing it from escaping. The gap between the window panes is filled with Argon gas to keep the cold out, and the separating spacers are coated with a low conduction material to hold more heat. In addition, the high-quality seals are double weather resistant to prevent rain or draughts incurring into your home. All of these features keep your home warmer, quieter and help reduce your energy bills.

Safe and Secure

All of our windows meet the British Standard for security, ensuring that your home has the highest level of protection. We use an internal glazing bead to prevent the glass being removed form the outside. In addition, our windows are all fitted Shockbolt Locking Secured by design and Fire Escape as standard.

Assured Certified

We are an Assured Certified installer. Assure is an official, UKAS-accredited Competent Persons Scheme authorised by the Ministry of Housing, Communities and Local Government (MHCLG) for the replacement of windows, roof windows, roof lights and doors in England and Wales.

Every project is automatically registered and backed by a 10-year warranty, providing further peace of mind and guaranteed satisfaction for our clients.

We can provide a range of UPVC window styles, including:

UPVC Casement Windows

A casement is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows are often held open using a casement stay.

Astragal Bar Windows

Astragal bar windows are where the bars are planted on to the glass. They separate panes of glass, giving the effect of traditional period features.

Georgian Bar Windows

Georgian bar windows are where the bars are sandwiched between the pains of glass, creating the Georgian window style but remaining easy to clear and maintain.

Residence 9 (R9) Windows

Residence-9 Window – R9 is manufactured from a modern composite material to give a virtually maintenance free finish. It is a new window system designed to replicate the 19th Century Flush Timber Windows.

Sash Horns Windows

Our vertical sliding sash windows range is the ideal replacement for traditional vertical sash windows. Weights and pulleys are replaced by innovative spring and spiral balances, and they come with a unique tilt facility on both the upper and lower sashes to enable easy cleaning.
