What is the best glass for bifolding doors?

One of the biggest driving factors for purchasing Bifold Doors is to have lovely big areas of glass, to bring light into your home.

High quality bifolding door systems will always be fitted with top quality glass of a good specification.

If you are building a new extension, the obvious benefits of bifolding or even sliding doors will be as clear as the glass as your new extension is flooded with light.

If your extension also comprises a lantern roof, you will benefit even more.

What do I need to consider?

With so much glass now in your room need you be concerned about heat loss, solar gain and increased noise levels?

The answer to these questions is generally no, but it is worth having some information beforehand.

Many bifolding doors are offered with “standard” double glazed units.  The glass itself will be safety glass – either toughened or laminated.  However what else will you get with standard double glazed units?

Typically the glass sheets used to manufacture the double glazed units in your doors will be from Pilkington, Saint Gobain, Glaverbel or a company of similar standing.

Modern double glazing found in your new bifolding doors will typically be:

• Toughened or Laminated Safety Glass
• Warm  Edge Spacer bars
• Argon Gas fill
• Soft coat Low E coating

With many quality bifolding door systems, the above glass specification is acceptable and more than adequate for the typical residential or commercial installation.
