Energy Saving Windows

Replacement windows come in a range of styles and designs and there are particular features you should look out for to increase energy efficiency.

To find the right windows for your home, ask yourself these questions:

How energy efficient are the windows?

When choosing replacement windows, you can check its energy efficiency by looking at the Energy Saving Trust Recommended logo and BFRC energy label. The higher the energy rating, the more energy efficient it is. Unfortunately, at the moment there is no obligation for window manufacturers to label their products, however by opting for a high rated window you know you will be buying the most efficient.

For a list of all windows and their frame material and energy rating, visit the BFRC website.

How many layers of glass do you need?

Double glazing has two layers of glass with a gap of around 16mm between them. There’s also the option of triple glazing, which has three layers of glass. Both A rated double and tripled-glazed windows are available.

What type of glass is best?

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. It lets sunlight and heat in but cuts the amount of heat that can get out again.

What’s between the panes?

Very efficient windows might use gases like argon, xenon or krypton in the gap between the 2 sheets of glass.

What keeps the panes apart?

All double glazed windows have pane spacers set around the inside edges to keep the two panes of glass apart. For a more efficient window, look for pane spacers containing little or no metal – often known as “warm edge” spacers.

The BFRC window energy rating scheme checks all the components to ensure the final window achieves the energy efficient standard claimed. This means that you just need to look for the A-G ratings and remember A is best! Alternatively, just look for the Energy Saving Trust Recommended logo which will only be found on glazing that is C rated or above.

Which frame suits your home?

The frame you choose will depend on your home and your personal taste. For all frame materials there are windows available in each energy rating.

• uPVC frames are the most common type. They 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. They 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

Do you need ventilation?

Because replacement windows will be more airtight than the original single glazed frames, condensation can build up in your house due to the reduced ventilation.

If there is not a sufficient level of background ventilation in the room some replacement windows will have trickle vents incorporated into the frame that let in a small amount of controlled ventilation.

Condensation can sometimes occur on the outside of new low-e glazing. This is because low-e glass reflects heat back into the home and as a result the outside pane remains cool and condensation can build up in cold weather – this isn’t a problem.

October has followed on from a good September

So Autumn has well and truly arrived and with it a cracking start to October which followed a great September. It is this time of year when we do expect to be busy but after the iffy start to January and February I’m feeling buoyant.

Sales leads are now up on this time last year and our conversion rates into jobs are also up. I did renegotiate terms and prices with our current fabricators and have passed them on to our customers.

Our sales in Composite doors are on the up to after a great year last year and I think this is set to get bigger and to continue to grow in a rapidly expanding marketplace.

I’m feeling confident within the whole Double glazing industry after chatting with suppliers, colleagues, competitors, and friends so let’s keep the phones ringing and the sales coming in.

I think this is just what we all needed after the WER’s fiasco and how to be compliant which sent some confusion and anger throughout the industry, but seems to have settled down now.

Here’s to Winter and not forgetting Christmas is only just round the corner then after that comes the dreaded VAT hike!

A few hints on buying Double glazing

Energy efficient Double glazing isn’t as expensive as you may think, and it also has many benefits, including cutting down on central heating costs and your carbon footprint.

A good double glazing installer will have experience in double-glazed windows and doors, French windows, bay windows and conservatories.

Helpful hints

·         Double glazing companies are often but not always less busy during summer, so you may be able to negotiate a good price for your double glazing project during the summer months.

·         For double glazing projects or double glazing repairs, obtain detailed quotations from at least three double glazing firms, outlining costs and timescales, and ask to see samples of their products.

·         Ensure your double glazing contract states when and what you will have to pay, and make sure you're happy with all the terms before you sign it.

·         Good double glazing companies will give guarantees for all the work carried out, but if the double glazing installer goes out of business you will have trouble claiming. To avoid this, you can use a guarantee scheme to insure the work and materials.

·         Some double glazing companies will be prepared to negotiate, so don't automatically accept the first price and it might be a good time to buy before the VAT hike in January.

·         Ask to see examples of work the double glazing company has carried out that's similar to your project - a good glazier will be able to show you examples of everything from French windows to bi-fold doors and conservatories.
