  • Smaller energy bills: replacing all single-glazed windows with B-rated double glazing
    could save you around £165 per year on your energy bills.

  • A smaller carbon footprint: by using less fuel, you’ll generate less of the
    carbon dioxide that leads to global warming - typically, 680kg a year.

  • A more comfortable home: energy-efficient glazing reduces heat loss
    through windows and means fewer draughts and cold spots.

  • Peace and quiet: as well as keeping the heat in, energy efficient-windows
    insulate your home against outside noise.

  • Reduced condensation: energy-efficient glazing reduces
    condensation build-up on the inside of windows.

The costs and savings for energy-efficient glazing will be different for each home and each window,
depending on the size, material and installer. Double glazing should last for 20 years or more.


PVC Sash Window 1

Double-glazed windows have two sheets of glass with a gap between them, usually about 16mm,
to create an insulating barrier that keeps heat in. This is sometimes filled with gas. Triple-glazed windows
have three sheets of glass, but aren’t always better than double-glazed windows: to choose the most
energy-efficient window look for the BFRC rating and Energy Saving Trust Recommended logo.

Energy-efficient windows come in a range of frame materials and styles. They also vary, depending on:

  • How well they stop heat from passing through the window
  • How much sunlight travels through the glass
  • How little air can leak in or out around the window.




Composite Doors from VEKA don't only look stunning, they also offer outstanding levels of energy efficiency
to keep your home warm whatever the weather.


Energy efficient foam is a key component of the inner core of a VEKA Composite Door,
providing the door with high levels of both thermal and acoustic insulation,
equivalent of up to six times that of alternative products. The foam is environmentally friendly 100% CFC free Polyurethane.

Every style of VEKA Composite Door complies with the very latest Building Regulations
which were announced in October 2010 and state that all doors must have a
minimum U Value of 1.8. A U Value is a measure of the heat loss through a material
and the lower the number, the better that material performs. Every VEKA Composite door
performs better than the minimum standard set out in the Regulations -
all styles achieve a U Value of 1.6 or less, with some styles boasting an impressive U Value of just 1.0.
