Energy Ratings

All our windows are rated for their energy efficiency. Many people will be
familiar with the ratings that are given to white goods such as fridges and
washing machines, which are graded between A and G, depending on their
environmental efficiency – A being the best and most efficient. What is less
well known is that the same system can be applied to doors and windows as well.

Rating Value (A-G)

This is the most recognisable and visible element of the label, showing
clearly the product’s energy efficiency in coloured bands, from the dark green A
(the best rating) through to the dark red G (the lowest rating and therefore the
least energy efficient). Obviously, products valued at A are the most
preferable. Building regulations currently stipulate a minimum requirement of C
(or a U-value of 1.6 W/m2K).

Thermal Transmittance (U-value)

This indicates the amount of heat energy transmitted through a door or
window, set out in watts per metre2 per degree Kelvin. This is a contributing
factor to the Rating Value above. The lower the U-value, the less energy is
lost, and the more efficient and economical the unit.

Solar Factor (G-value)

This represents the amount of solar energy that is gained through the window.
The higher the value, the more energy gained and the greater the saving.

Effective Air Leakage (L-value)

This is the amount of air that permeates through the window weather seals,
also a contributing factor to the Rating Value above. Modern high performance
windows will have a low air leakage rate.

The benefits of energy-efficient windows

• 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.

To get a better idea of how much you could save by replacing your windows, use the
Energy Saving Calculator at the Glass and Glazing Federation’s website,
developed with the Energy Saving Trust

How energy-efficient glazing works

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.

What to look for

• Glass: The most energy-efficient glass for double glazing is
  low emissivity (Low-E) glass. This often has an unnoticeable coating of metal
  oxide, normally on one of the internal panes next to the gap. This lets in light
  and heat but cuts the amount of heat that can get out.
• In between: Very efficient windows might use gases such as
  argon, xenon or krypton in the gap between the sheets of glass.
• Pane spacers: These are set around the inside edges to keep the
  two panes of glass apart. For maximum efficiency, look for pane spacers
  containing little or no metal – often known as ‘warm edge’
  spacers.

Frame materials

For all frame materials there are windows available in all energy
ratings.

• uPVC frames last a long time and can be recycled.
• Wooden frames can have a lower environmental impact, but
  require maintenance. They are often used in conservation areas where the
  original windows were timber framed.
• Aluminium or steel frames are slim and long-lasting, and
  can be recycled.
• Composite frames have an inner timber frame covered with
  aluminium or plastic. This reduces the need for maintenance and keeps the frame
  weatherproof.

Energy rating

Some window manufacturers show the energy efficiency of their products using
an energy rating scheme from A to G - like the one used for appliances such as
fridges. The whole window (the frame and the glass) is assessed on its
efficiency at retaining heat. The scheme is run by the British Fenestration
Rating Council (BFRC). Find more information on the BFRC website.

Energy Saving Trust Recommended

The most efficient windows (B and above) can also carry the Energy Saving
Trust Recommended logo.

criteria for glazing.

Ventilation

Replacement windows will be more airtight than your original frames, so
condensation may build up in your house due to the reduced ventilation. If your
house does not have much background ventilation, look for replacement windows
with trickle vents incorporated into the frame to let in a small amount of
controlled ventilation.

If you start to see condensation building up around your windows, there may
be a damp problem in your home. As a general rule damp occurs when there is
inadequate ventilation, inadequate heating, inadequate insulation or a
combination of these. If you’ve started to notice condensation in between the
panes of glass in your double-glazing units then it is likely that the seal is
broken, and the unit will need to be replaced.

Windows in period properties

If you live in a conservation area or a listed building there may be
restrictions on what you can do to your windows. There are a number of
non-intrusive window insulation options available for historic homes such as
heavy lined curtains, shutters, secondary glazing and sealed blinds. However,
each historic building is considered individually so check with your local
council to see what options are available to you.

Conservation areas

These areas are of special architectural or historic interest, meaning that
any work you carry out on your home must preserve or enhance the character of
the area. This does not necessarily mean you cannot replace your windows, but
might mean you will need to get windows that complement the character of the
building and area. Double glazing can be made to look like your building’s
original windows, but for any changes you do need to contact your local
council’s conservation officer for guidance.

Listed buildings

Listed buildings have tight controls on what you can change on the outside
and sometimes the inside as well depending on their grading. Old sash windows in
historic properties can be protected not only for their appearance but also the
materials and methods used to make them. But secondary glazing can be a
non-intrusive way of insulated historic windows from the inside, and may be
granted permission.

There are other ways to make historic buildings more energy efficient but you
will need to consult and apply for permission from your local planning
authority.

See the English Heritage website for ways to make a historic home
more energy efficient.

Sash windows

Sash window units are common features of period properties and can be a
design feature. They consist of two vertically sliding frames, but are often
badly fitting and made of single pane glass so have poor insulating
qualities.

If you want to insulate your sash windows there are a number of alternatives
to conventional double glazing. If you want to keep the design and look of the
sash windows, there are units available that are in keeping with the original
design; these are fitted and sealed to prevent draughts and incorporate double
glazing to reduce heat loss. The frames don’t need to be plastic, but can be
metal or wood with an insulated core.

An increasing number of double glazing companies offer double glazing in
period properties. Replacing sash windows can be expensive, though, so
good-quality secondary glazing may be worth considering.
