Upvc windows and low-e glass?

Question

I am thinking of getting a couple of my windows replaced with upvc windows, one window fitter was going to replace them with low-e glass, and another fitter told me that the low-e glass is a bit of a con as you don't really see any benefit from it and normal glass is just as good really and cheaper (and he seemed to really know what he was talking about),anyone know for sure ??

Answer 1

I work in the window trade and ill think you'll find replacement windows have to be energy efficient to meet Document Part L.

We just moved to FL, had all of our windows changed out to Low E from regular windows.  There was a difference (a drop) on our electric bill, and a huge difference with the afternoon sun/heat pounding against the old windows vs. the new Low E ones. We had ours done a year ago, and I don't know what "upvc" means, however windows do have a grade, maybe that's in reference to the grade?  

When in doubt, check various places such as Lowes and Home Depot or even specialty window places just to get further insight, education and information before investing.  This is also a good way to verify prices amongst competitors.  As the market for home improvement is very slow, you have the advantage at this time to negotiate with independent dealers (if this is who you end up chosing).

Just a thought, independent window contractors may deal with just a few window suppliers, therefore makes their resources to the consumer limited as well.  There's a possibility that this contractor is pushing what he has, without coming across this way, to you.

Be aware of contractors in general.  Verify if they are licensed and bonded (don't know what state you're in, each state is different, check out the State Contractors Board for details that'll protect you as the consumer).  Some states require that contractors for windows be licensed and bonded.  We thought we were savvy shoppers, aware of what to be cautious of when choosing a contractor, however, a few will slip between the cracks.  We were overall satisfied with our window guy.

We chose an independent.  He was good and his prices were fair (better than Home Depot and Lowes).  We were out of state when the installation was done. Suggestion:  Someone be at the home when any work is done (This was our disadvantage at the time)

Hope this tidbit of consumer insight helps.
