Windows

We can supply and fit a wide range of windows to suit any requirement.
PVC-U (also known as uPVC) are our most popular product as they are cost effective, smart and virtually maintenance free. We can also now supply our Double Glazed PVC-U windows in a huge choice of colours. With the latest technologies providing excellent weather protection, security and strength, our windows offer exceptional insulation and energy efficiency.
Our PVC-U ranges provide excellent value for money and will give many years of service.

We also supply and fit sash windows, hardwood windows and aluminium windows. We have a large range of glazing options available including double glazed and triple glazed, Georgian bar and leaded finishes. We can also supply internal blinds- where the Venetian Blinds are located within the sealed double or triple glazed unit so they never need cleaning and are permanently protected.

Some of the popular types of windows that we supply and fit:

  • Classic Casement Windows
  • French Casement Windows
  • Flush Casement Windows
  • Tilt-And-Turn Windows
  • Fully Reversible Windows
  • Vertical Sliding Sash Windows
  • Georgian Astragal Bars
  • Triple-Glazing options
  • Integral Blinds

We can also carry out repairs and servicing for your windows, as well as replace failed double-glazed units (for example with internal condensation).

Internal Blinds

Our windows can be ordered with Venetian, blackout or pleated blinds fitted within the double or triple glazed units.

Comparison of Double Glazing Types

Double glazing prior to the early 2000s was basic, using 2 layers of glass in a unit filled with air.

Around the early 2000s, thermal efficiency of double glazed units was addressed; gases and softcoats, or low E glass were used. This created a requirement to meet certain U values. These have been constantly improved and lowered with improves thermal efficiency to where we are today.

Secondary glazing adds a third layer to double-glazing. This can be added to pre or energy rated double glazing to create a quieter and warmer environment.
