Double-Glazed Window Suppliers/Contractors/Fitters

lhylat

I have had a look through all the forums in relation to Double-Glazed Suppliers/Contractors/Fitters and have found some interesting stories. I am currently looking for windows and have received 5 quotes and there are differences in pricing (one company is double another company's pricing). Can anyone give me feedback good and bad on <SNIP>

I really appreciate it and many thanks in advance for your time.:)

HI,

I live in NTH Dublin, and would be interested in the previous questions in this post.

I just viewed a house that would most certainly need new windows.

Is there buy the front, get the back ones at a better price, or anything along those lines?

How likely is anyone in the current climate able to pay the windows off along with the mortgage. I have used the incorrect wording, I know, but at this exact moment the term escapes me.

Thanks in advance

Before you decide check what they ofer.
the main factor of windows is a u-value. if all supliers ofer the same then u can take lower price.
but
when j was getting windows J was told windows have u-value 1,1, and price was ok for me but then j spoke to others and j found this u-walue is just for glass and frame was 2,4:mad:
so jm still looking for a good u-value windows 0.8 to 1.1 in a good price
cos most of heat is lost through windows

Many thanks for your reply and useful information? Is the u value the quality/dimension of the glass?

Can I ask do you know about the gas contained in windows and how I make a judgement on that?

many thanks:)

Hi Ihylat
Yes u-value depends what size is window and quality of glass and frames.
material itself has factor "lambda" wich you can use to calculte the "u"
when you get a u for glas, for ex. 1,1 and frame has 2,5 then whole window has about 2,5 wich is quiet bad, the openings makes u-value worse.
the good window must have 1,1 where glas has 0,8 and frame 1,1.

The U-value is a measure of the rate at which heat is lost through the window (or other parts of the building - e.g., you can calculate the U-value of a wall). For U-values, a lower value is better.

If you're buying an old house which needs new windows, there's a good chance it could do with other work to improve its energy efficiency.

The new SEI Home Energy Saving scheme doesn't cover windows, but would make a contribution towards a "before" and "after" BER assessment, as well as other works such as improved insulation, more efficient boiler & heating controls, etc.

A BER assessor will be able to advise on all aspects of your house's energy efficiency, including the windows.

nearly all the times, supliers are talking about u-value of the glass and they're misleading that it's the most important thing.
but theres nothing more wrong.
its very simple to make the good quality glazing. the problem is in the frame.
usually u-value for the glass is 1,1 but frame is 2,5 wich is quite bad, becouse total u-value for a whole window is about 2(depends on proportion of the frame and the inside of the glass)
so when you'll be buying windows check both u-values
