Are Aluminium Bifold Doors a Good Choice for Homes in the UK?

[NightHollow]

A friend of mine recently renovated his kitchen and replaced the old patio doors with aluminium bifold doors, and the difference in natural light was impressive. I've been considering something similar for my own home, but I'm a little concerned about heat loss during colder months. I've noticed that modern bifold systems offer double or triple glazing, which sounds promising for insulation. Has anyone installed aluminium bifold doors in the UK, and how well do they perform during winter?

I’ve got Trade Aluminium bifolds installed and they keep the heat in well even during winter. The double glazing on mine gives a U-value of 1.4, so no draughts or cold spots. Definitely worth considering if you’re worried about performance in the colder months.
