What are Ecoease glazing panels made from?
Ecoease secondary double glazing panels are made from PolyEthylene Terephthalate, better known as polyester or PET. PET was patented as a fibre forming plastic by J R Whinfield and J T Dickson while working in the laboratories of the Calico Printers Association in Accrington, Lancashire in 1941. After secret development work during the war, in 1947 an agreement between ICI and Calico Printers Association gave ICI the world rights to make polyester fibre, except in the United States where DuPont owned these rights. Commercial production of ‘Terylene’ polyester fibre commenced on Teesside in 1955.
The intervening 55 year period has seen PET developed into many new forms and used in many new applications in addition to fibres, such as carbonated soft-drink bottles, thermoformed food containers, and in a wide variety of high-quality industrial and commercial applications. Each new application has made full use of the outstanding properties of this remarkable material to the extent that it has become the dominant material used in each of these applications.
Why do we use PET glazing panels for Ecoease?
PET is the ideal glazing panel material because of its unique range of properties, which include:
- Extremely high impact-resistance - try dropping a full PET cola or lemonade bottle to see if it breaks.
- Excellent fire-resistance - Class 1 according to BS476 Part 6 ( basically wont burn)– Acrylic sheet is only Class 3( makes great fire lighters)
- Light-weight - about half the weight of glass of the same thickness.
- Excellent thermal and acoustic insulation performance – more than 10% better than glass.
- Safe for the environment – PET contains only carbon, hydrogen and oxygen molecules – no Bisphenol A, no ozone-depleting materials, no acid-rain causing ingredients. PET is classified worldwide as a food-contact safe material. It is also the most recycled plastic material in the world today!
