Why Do We Need Double Glazed Glass ?

Double Glazed Glass has been widely used since the 1970’s and really gained in popularity during the 80’s and 90’s.

Gone are the days where soaking up the damp from your window cill and eating your breakfast in your long johns and winter coat where an every day occurrence , Double Glazing has become a modern day necessity and is here to stay.

What Is Double Glazing ?

Double Glazed Glass is usually constructed from two pieces of 4mm glass and a silver, bronze or black spacer bar.

The idea between this construction is that a thermal break is created between the two glass panes which slows the transfer of heat from the inner to outer pane.

Spacer bars are filled with Desiccant, Desiccant is a substance which is designed to remove moisture from the air therefore greatly reducing condensation.

Additionally, in the case of A-Rated Glass the thermal break is then filled with Argon Gas which further promotes the energy saving properties of the unit.

UPVC Windows Online – FAQ

What Are A-Rated Windows

An A-Rating is achieved by combining a UPVC Window ( Often made from virgin plastic, That has 3 or more Thermal breaks inside the profile for added efficiency ) Combined with A-Rated glass. Most windows on the market today are more than capable of achieving this and are often sold A-Rated as standard.

What Is A-Rated Glass

A-Rated Glass is usually produced by using two pieces of 4mm glass ( one piece softcoat and one piece standard glass ).

A cavity is then created by what the industry call, a Warm Edge Spacer Bar ( Sometimes referred to as a Super Spacer ) these replace the outdated Aluminium Spacer Bars which are less efficient. The cavity is then filled with argon gas which completes the process.

What Is A Standard Window Size

UPVC Windows come in all different shapes and sizes, unfortunately this does mean there is no standard size.

It is possible to buy UPVC windows at some DIY outlets although there will more than likely need to be some creative trimming and filling involved as these windows will not have to been made to be a perfect fit. In other words, made to measure is better and less hassle.

Do My Windows Require Trickle Vents

If you are having an extension built then the answer is a most likely yes.

If you are simply replacing the existing windows for new ones then a general rule of thumb is if your windows are already fitted with trickle vents then the replacements are also required to have these installed.

If you don’t currently have trickle vents then you may be able to get away without. In either case it is always best to ask your local council first before going ahead without.

How Much Is Too Much  ?

 You need new windows, you have some quotes but cant make out what you should be getting for what price, so the question arises “ How Much Should I  Pay For Double Glazing ? ” and how do I avoid being ripped off.

National Or Local ? 

Is There a difference between the larger national and smaller local companies? Yes !!

National Company’s 

  • Have pushy salesman that are normally on at least a 10% commission for selling the company’s products 
  • Are notoriously difficult to communicate with, especially post installation with small snagging jobs.
  • Start their pricing above and beyond what should be the going rate, but are normally willing to drop there prices to gain a sale ( often more than 50% ) 
  • Products are normally well manufactured and should comply with insurance regulations. CERTASS and FENSA certified 
  • Less likely to go out of business and usually have a quicker turn around time. 

Local Firms 

  • Normally an owner or director of the business will be your first contact who has often had many years of experience in the window industry and can answer all the questions you have. 
  • Communication is often directly with this person so being sent around the houses is mostly avoided.
  • You wont have to practice your negotiating skills here as most local business know everything about their competition and are eager to build there local brand and reputation by offering a fir price.
  •  Products are normally the same if not better than some of the national company’s and come with all the same guarantees.
  • Are normally Certass or Fensa registered. Some local businesses may opt to go through the local council and building inspector for the paperwork side of things,  This approach in many respects is better as it involves a third party who is impartial and non bias so will almost always insure everything is in order however is the more expensive option for the window firm.
  • The worry of your local window company going bankrupt is often negated by an insurance backed guarantee which protects the customer in the event that your local business has fallen on hard times. 

How Much Should It Cost ?

The cost for an average sized window ( around 1200mm x 1200mm ) should cost somewhere between £350 – £450 supplied and fitted depending on ease of access and what type of windows are being removed.

A larger window ( around 1800mm x 1200mm ) can cost anywhere from £400 – £600 depending on the same parameters.

Other Options

Another way to save money and often the more cost effective option might be for you or your builder to order your new windows from a supplier such as ourselves or many other companies on the internet who are able to supply these windows at a lower cost as we are able to broker a better price per unit compared to other window firms or retail outlets.

Builders regularly charge anywhere from £75 – £150 ( Labor Only ) per window and will call on a third party building inspector to certify your windows are up to date with the latest building control guidelines. Having this building certificate is important as you will need this if you ever decide to sell your property.
