Cost effective total window replacement

[Ommm]

I'm wondering how to approach a project where I need to replace all of the 1970s/80s aluminium double glazed windows of a property in south west Surrey.  The main problem is there are lots of windows and some of them are large, and I want to do it to a reasonable thermal spec (lots of glass area = heat loss) while on a limited budget.  To give an idea, there are 11 windows and 5 doors (inc 3 sliding patio doors) - the doors are roughly 2.4m x 2m and the largest window is 3m x 1.2m.

 

To keep the budget under control I'm probably looking at uPVC. What might be options for suppliers?  I can of course ask the local firms around to quote, but I'm wondering if there's any good value 'IKEA' or 'DIY Kitchens' kind of fabricators who I can source the windows from and then find someone to install (I know someone who might do it). I know there's plenty of 'buy windows online' kind of places but I don't really know who are good companies beyond just random Googling, and many of the quoting tools don't say who makes the profile they're using so it's hard to gauge quality.

 

There used to be a window factory down the road but it's now a block of flats...

Trouble with most windows you mostly get what you pay for. Argon filled double glazing is argon filled glazing, the frame design is the difference between a a good window and a poor one. So when comparing look at the U_w that is the U value of the whole window, not just the glazing (U_g).

 

Also make sure the installer is filling the void around the window, ideally with an airtight foam. Lots fits window and just cover the void circumventing a decent U value.

I have used Modern UPVC Windows for both windows and doors and not had any problems. I think they are good value for product and service. I did fit them myself though.

A friend has used this company twice & has been pleased both times.  They've just fitted a long bi-fold run, separate slide or French patio doors (can't remember which) & 6 or more other doors/windows to his house extension.   They supply & fit.  

 

https://truglaze.co.uk/  They're in Frimley Green, so probably not far from you.

 

Please let us all know how you get on - I have a rental property that will need new windows within months (assuming the tenant moves out, as expected).

just chucking them in yourself might cause an issue when you come to sell it as you wont have a fensa certificate.

 

you can use websites like, modernupvcwindows to get an idea of what you want then an idea of cost before you get some quotes.but dont forget the installer will price in trims/foam/silicone/packers/fixing etc.. 

 

i have eurocell in my house because they are round the corner from me and noise reduction Liniar in my garage because i got them off marketplace off some crackhead. I put a crystal from the bargain bin section in wickes in my mates garden room/playhouse because it was £20.

 

These is a quite a bit to it and once you take your old one out you have to get the new one in by the end of the day or it gets chilly.

For me, Aluplast, specifically the Energeto 8000. Is it the cheapest? No.

I just screw a bit of OSB in the hole and finish it the next day, and don't do it in mid-winter.

The amount of chambers, welds, material used (polybutylene terephthalate (PBT) engineering plastics rather than steel for strengthening and thermal improvements
