Here, at Window Monkey, we do not pressure sell. We have an easily accessible Showroom in Leighton Buzzard for anyone living in Bedfordshire, Buckinghamshire or Hertfordshire. That means you can visit us, any time you like, to find the windows, front doors, bi fold doors or sliding doors that are right for you without being annoyed by that outdated salesman approach.

However, we are still here to help. So, just ask one of the team for a chat if you need us.

Sheerline Window Example

Exceptional Style, Exceptional Thermal Efficiency

With Sheerline’s Aluminium Windows you can have exceptional performance in a window that looks equally exceptional.

Their Classic system has been designed, from the ground up, to be astonishingly thermally efficient and, together with the choice of a traditional or contemporary sash style in either a standard outer frame or as a ‘Flush’ option, they can look great doing it.

In other words, you can get an Aluminium window that truly matches best with your home’s character, keeping it warm in the process.

Unrivalled Security, Unrivalled Sustainability

The Classic window system is constructed using a patented corner jointing method which keeps the glass sealed in and tight, which means no more glazing beads. This takes away a massive area of weakness in traditional window designs and, together with their high security multipoint locking and unique hinge protectors, they are ‘Secured By Design’ as standard with PAS24:2016 enhanced security accreditation.

With aluminium being one of the most sustainable materials on the planet, and Sheerline’s Classic system of windows being manufactured in the most energy efficient aluminium window facility in the UK, you have to ask if there is anything they haven’t thought of?
