Triple Glazed Bifolding Doors frequently asked questions.
30 June 2017
The Alufold Warmcore bifolding door is available with a choice of both double or triple glazing. What is best for your home, double or triple glazed bifolding doors? We answer some frequently asked questions.
Are triple glazed bifolding doors better?
What is best? Triple or double glazing in bifolding doors?
The benefit of triple glazing is increased thermal and acoustic performance. However, it is important to explain that triple glazing does not take the place of actual ‘acoustic’ glass. Acoustic glass is specially designed to reduce sound levels and often specified in city centre commercial buildings needing specific sound levels.
It is unlikely that you will need acoustic glass in your home, however the extra layer of glass found in a triple glazed unit, does make the unit acoustically better than a standard double glazed unit.
The other important thing to consider with a triple glazed door is that you are looking through three pieces of glass. Therefore some minor visual differences are inevitable. Contact us, and we can explain these to you.
What about thermal performance with triple glazed bifolding doors?
A triple glazed Alufold Warmcore door is one of the most thermally efficient doors on the market. With a triple glazed unit, Alufold doors provide a U-Value of 1.0Wm2K far exceeding the requirements of current Building Regulations at 1.8Wm2K.
The unique thermal core of our double glazed Alufold Warmcore doors gives you a U-Value of 1.4Wm2K which is better than many of the leading bifolding door brands in the UK. It is the advanced thermal core in combination with our glass that makes Alufold so thermally efficient.
Are triple glazed bifolding doors more expensive?
Yes. The extra materials and manufacturing required in making a triple glazed unit add to the cost of the glass and the price of your bifolding doors. Can we help you weigh up the cost versus benefits of triple glazed units in your new Alufold Warmcore bifolding doors?
How can I decide what is the best glass for my bifolding door?
There are some considerations you will need to think about. One of these is the overall specification of your doors. Double glazed doors use 28mm units; triple glazed Alufold doors use 44mm units.
- If you want integral glass blinds for your bifolding doors, double glazing is satisfactory.
- If you want the maximum energy efficiency from your bifolding doors, choose triple glazing.
Alufold doors are bespoke and designed to give you the most options possible. We offer colour choices, premium handles, colour matched gaskets and welded construction. The choice of double or triple glazing gives you added choice.
Your decision to use triple glazing in your new Alufold doors is mostly based on cost, energy efficiency and the acoustic benefits you can expect to gain with triple glazing.
Are triple glazed bifolding doors heavier?
Yes. The extra piece of glass and additional components in your bifolding door make each door panel heavier than a double glazed bifold. This is not necessarily a concern as all our doors are engineered to take the extra weight, with no loss of reliability or long term performance.
