Our Energy Rated Products

 

Energy 'A' Rated Windows

Recent developments in the double glazing industry now means double glazed windows can be rated the same way as white goods, such as fridges can. This simple scheme controlled by the BFRC (British Fenestration Rating Council) allows windows that have been put through a rigorous testing process to display a rating from A – G with an A rating being the best.

IGLU now sell two fantastic Energy Rated windows.

 

‘A’ rated IGLU Energy Max

‘C’ rated IGLU Energy

 

There are two major reasons why you should choose windows that carry a ‘C’ rating or higher when you improve you home;

 

1. They are better for the environment

2. They save you money

 

In simple terms, energy rated windows utilise the suns FREE solar power to help heat your home.  Excellent insulation qualities ensure that ‘heat loss’ through your windows is kept to a minimum.  Both of these functions result in your heating bills and energy consumption being dramatically reduced.

 

Only windows that carry a ‘C’ rating or higher are considered ‘Energy Saving’.

FREQUENTLY ASKED QUESTIONS

 

What is an Energy Efficient Window and how do they work?

The latest energy efficient glass is called 'low emissivity'. This glass contains an invisible metal coating on one of the two sheets of glass that make the window. This makes the glass reflective, keeping heat in and the home warmer in the winter and reflecting heat back in the summer, making the home cooler.

 

How can I tell if the windows I am going to buy are energy rated?

Look for the BFRC label and talk to the supplier.

 

Does the energy efficiency rating just apply to the glass in the window?

No. In the BFRC rating scheme the whole window (including the frame and any casement) is rated on its energy saving properties.

 

I notice that a B rated window has a negative value and an A rated window usually has a positive value what does this mean?

This figure is the Energy Index and it shows how much energy the window will save or lose once it has been installed, this will depend on the building, local climate and indoor temperature.

A positive value means the window will enable more energy (free heat) to pass through the glass and into the room than is going to be lost through the window, therefore the window is a 'free energy' supplier.

 

How much do Energy Efficient Windows cost?

The cost varies not only between the various ratings (A to E) but is also dependent on the frame materials used and the size and style of window. A rated windows will usually cost more than B, C, D and E rated windows, but this has to be set against the energy savings you will make as you go up the ratings scale.

The rule of thumb is that Energy Efficient Windows cost less than the heat lost through old windows, over a given period of time.

 

How do I find out how much I would save on my energy bills?

If you use an Energy Efficient Window supplier who is also a member of the Glass and Glazing Federation, they will use an Energy Calculator. This allows them to input information on your energy supplies, the cost of that energy, the type of property you live in, your existing windows and the type of Energy Efficient Windows your are purchasing. At a press of a button your annual energy saving can be calculated.

What’s more, a comparison in energy saving costs can be provided for the different ratings of windows.

 

 

How do I find out how much I would reduce my carbon footprint by installing Energy Efficient Windows?

It is generally recognised that if you live in a single glazed house and install Energy Efficient Windows you could reduce the energy you use by 0.30 tonnes (or 18%) per year. This calculation is based on ‘an average, semi-detached house’.

 

Does this rating system include glass doors and conservatories?

Glass doors are to be included in the BFRC rating scheme in late 2010. Conservatories are currently excluded.

 

What exactly is the BFRC?

BFRC (British Fenestration Rating Council) is a wholly owned subsidiary of the glazing industry’s trade association, the Glass and Glazing Federation. Its ratings scheme for Energy Efficient Windows is a voluntary scheme that uses energy labels specifically produced for windows that are similar to the energy labels seen on most household appliances.

It sets extremely stringent standards for windows to be rated.

The most energy efficient windows (rated A to C) also carry the Energy Saving Recommended logo issued by the Energy Saving Trust
