Bi Fold Doors

About to start a major project on the house adding extra rooms and living space.

While the first hurdle is to sell the current conservatory and a huge palm tree to raise some beer money. The main conundrum us who to use to source the bifold doors from

Any recommendations for a good firm / make in surrey / Hants / berks area

Hi Magic

I just recently went through a major house extension as well (60 odd m2 in total) and added a 3 meter bi-fold door in grey with integral blinds. The whole thing cost about 6k in total i think. Although its become a major feature of the house now, I'm not 100% sure it was worth the cost....

Avoid the UPVC ones, they are all sh!t.

Mine were manufactured by http://www.duration.co.uk/ and the build of the Alu doors is absolutely spot on. The integral blinds are ridiculously expensive but looks the nuts.

All I would say is let your builder do it - fitting them is an absolute nightmare and even if your builder adds a bit to the price you would be well advised to let him take the headache......

Any questions fire away!

Seriously, the upvc ones are awful. I would rather go for a 2 x 1 meter french door and a small glass panel over a upvc bi-fold. They are really flimsy in use as well. They also give you a high threshold to step over, whereas the alu ones are virtually flat with the floor...

Yep totally agree on that plus for this install I prefer but the boss has other ideas

I need to hunt around for a showroom that has both installed and demonstrate why one or the other I think

The main thing with UPVC that worries me is the sagging from heat expansion just the way my old french doors have in the conservatory as you said french doors would be nicer.

I think it will come down to budget as rather spend the money on kitchen upgrade then doors as looking at the alu ones they are lot more

If you are not worried about the integral blinds you should be able to get an alu door for around 1k per panel. Max per panel is 1 meter, so you should be able to get one for less than 3k all in....

The price I had for upvc was much less than you have been quoted, it was like 1800 for my 3 meter opening....

We've just had 10metres of bi-fold panels installed, 1 run of 5metres and a corner of 3x2.

I agree completely with the other comments:-
  • Definitely go with Aluminium (available in a range of colours)
  • Don't pay more than 1k per metre panel.
  • Larger the door the better, ie: 2 x large doors better than 3 smaller doors.
  • Integral blinds are a matter of choice, we looked at these and decided they weren't for us - prefer the clean lines

I got my doors from 1stslidingfoldingdoors,... http://www.1stslidingfoldingdoors.co.uk/ and would highly recommend them. They have a showroom in Middlesex and obviously supply all over. As you would expect, doors comply with FENSA and are guaranteed for 10years.

You can see a pic of the back of our extension here,...

Cheers.

Thanks for that appreciate it I have some homework to do but I think it will be either Alu Bifold or just french doors. Reading up on it the UPVC option is not a good one, especially with ours facing the hottest direction for the summer.

thanks again

PVC bi-folds are no longer as mentioned before they have moved on a far bit in the last 3 years you no longer have to have a massive step and the sight lines are similar to Ali bi-folds I find the Ali bi-folds do look very commercial sometimes the latest PVC bi-folds do not. However the Ali bi-fold is always going to be better than a PVC bi-fold but only if you have budget for a Ali-bi-fold

Spent some time reading up on it and agree even the good UPVC still get step over sills and dont come near the clean lines than Alu do. The other is security alu should be more secure as well

I've contact the firms above and see what they come back with , price will be one thing otherwise back to french windows with side lights.

So what's wrong with timber or timber/ali clad bi-folds?

I wouldn't give plastic windows/doors house room,ghastly product,and the ruination of many houses.

Kloeber do some gorgeous timber bi-folds,SBD accredited as well.

Personally, unless the opening was bigger than 3 panels, I would find it very hard to justify the extra cost over standard doors....

That's a good point. You may be better going with sliding doors to fill a smaller opening as you can then have two large paned sliding doors instead of 3+ paned bifold doors - ie: less frame area = more visible glass = more light.

I did think of sliding but got shot down on that idea.

I think it will be french doors as they work out nearly half the price of decent bifolds.

Unless I get a great deal at the home show on Sat
