Energy efficient glass is used in double glazing and triple glazing to help you reduce your heating bills – and improve your carbon footprint.

Most new builds will be fitted with energy efficient windows. And owners of older properties are advised to replace any single or old-style double-glazing with new, more efficient glass.

The principal difference between an orangery and conservatory is their construction.

Whereas a conservatory will typically have over 75% of its roof glazed, an orangery generally has less than 75%. Plus, over 50% of the wall area of a conservatory would also be glazed.

Both are popular with homeowners, but which you choose depends on the style of construction most suited to your requirements.

At Excellent Windows, all our windows, doors and conservatories are designed to British Security Standards and meet the criteria of the Official Police Security Initiative.

We only choose suppliers who provide first-class products and that includes the frames we use for our conservatories. Ultraframe offers the best, BSI approved, quality frames on the market, exceeding the latest industry standards.

That’s why we supply Ultraframe in a selection of colours and finishes, plus different options for configuration, frame style and glass.


Double glazing is one of the best investments you can make if you’re looking for ways to make your home warm and cosy this winter.

The insulation provided by double glazing limits the transfer of hot or cold air through your windows. As a result, your home stays warmer in winter and cooler in summer. Energy efficient glazing also enables you to cut your carbon footprint and reduce your energy bills.
