Is double glazing the right choice for you?

Double Glazing

Double Glazing - Is the glazing process in which a window is made with two panes of glass formed into one single window.

The two panes of glass are separated by a layer of trapped gas either Argon or Krypton gas. The layer of gas acts as a trap and is a poor conductor of heat, this helps to keep warm air trapped inside your home and not leaving by your windows and helps improve energy efficiency.

The second panel of glass acts as an extra barrier to the outside world which helps to reduce noise pollution into your home, thus keeping your home quieter. It also acts as another strengthening layer to help improve the security of your windows and home.

What is triple glazing?

Is triple glazing the right choice for you?

Triple Glazing

Triple Glazing - Is the glazing process in which a window is made with three panes of glass formed into one single window and offers the ultimate in thermal efficiency. Triple glazing is only available in our UPVc range of windows.

These glazed units have smaller internal chambers compared with double glazing which helps to reduce heat loss. The central glass panel reflects more heat making it warmer in your rooms and helps to reduce your heating costs. The gas used within triple glazed units is Krypton gas

If your home suffers from external background noise, triple glazing offers superior noise reduction to double glazing, giving you a warmer and quieter home. The units are ideal for north facing windows or where the windows suffer from little natural sunlight. Depending on the placement of windows and the elevation of your home, you may not need triple glazing in every area therefore you could mix and match double glazed and triple glazed units to suit your particular home. The Celsius team can help you choose the best combination to suit your individual rooms.

Will double or triple glazing reduce my utility bills?

How energy savings are made to help reduce your heating costs

How does this work?

Windows can have different energy ratings. If you are replacing older windows with our A+ rated double glazing units or our A++ rated triple glazing units you can be pretty sure that you will save energy and therefore money on your bills.

Savings can vary and will depend on the age of your existing windows. For example, pre-2002 double glazed windows were not filled with gas but instead were filled with air. Also, windows older than 10 years are likely to have some reduction in the efficiency of seals and other components which will mean you are losing energy through them. All these factors can contribute into the actual saving you will have for your particular home.

Due to the differences of window materials, glazing options and heating used within homes in the UK, the savings can range from £100 to more than £600 per year.

What range of materials can I choose from?

Are double glazed and triple glazed units available in all materials.

Aluminium Windows

Celsius aluminium windows - can only be provided and installed with double glazed units. However, Celsius Home Improvements can also manufacture and install aluminium windows using the WarmCore - Warm Aluminium system. This product offers greater thermal efficiency than traditional aluminium products.

UPVc Windows

Celsius UPVc Windows - can be provided and installed using either double glazed A+ rated units or triple glazed A++ rated units. These are also available in a wide range of colour options.

What do energy ratings mean?

We help you to understand what energy ratings are and how they effect your home.

Ratings Explained

A number of factors influence the energy efficiency of the window. These include the profile system and the specification of a sealed unit.

Windows are rated from A+ (no heat loss at all) through to G (extremely energy inefficient), the window Energy Rating label allows you to see at a glance how energy efficient a window is.

Windows Energy Ratings are calculated using various values:

  • Thermal Transmittance (U value)
  • Solar factor (G value)
  • Air Leakage (L value)

The thermal transmittance or U-value represents how much heat can escape through the glass. This is measured in Kilowatt-hours, per square meter, per year.

For example: 3.5kWh/m2.K - This means that 3.5 kilowatts of energy is lost through every square metre of the window every year

The solar factor or G-value represents how much energy is gained through your windows from the Sun. This is measured in kilowatt hours per metre, per year.

The Air Leakage or L-value represents exactly what you would think, how much air is leaked through the windows (the lower the better). This is measured in kilowatt hours per metre, per year.
