If you’re considering having the roof of a room replaced you’re probably thinking about what material will be best for the job. There are plenty of materials you can choose from but I urge to avoid traditional materials like slate and wood and instead thinking about utilise ETFE foil.
ETFE foil is a transparent roofing material with excellent insulation properties and a whole range of additional benefits. Although using this fibre will probably be more expensive than traditional materials, it will save you a lot of money in the long run. ETFE foil is extremely energy efficient and will help you keep energy bills down.
ETFE foil is a relatively new material so don’t be surprised if you have never heard of it before.
ETFE Foil Properties
As I mentioned earlier, ETFE foil is almost completely transparent, and it can transmit the entire visible spectrum range. It can also transmit almost all of the UV range, but this material will not be damaged by UV radiation the same way other roofing materials are. ETFE stands for Ethylene Tetra Flouro Ethylene, and it is a form of modified copolymer with very strong insulation qualities.
You can buy ETFE foil in one of two ways; as a single layer membrane or a multilayer of between two to five layers of foil covering the membrane. I recommend that you opt for the multilayer option as the more layers the foil has the better the insulation values will be. In fact, a triple layered ETFE foil panel has better insulation values than that of a triple glazed window. The foil panels are kept in place by aluminum perimeters, and these in turn are attached to the main building frame.
Even though ETFE foil offers better insulation than a window, it only weighs 1% the weight of glass. This makes it very easy to work with and an ETFE foil panel installation generally takes a shorter amount of time than the installation of traditional roofing materials. Although the foil is very light, it also quite strong and can support up to four hundred times its own weight, meaning you don’t have to worry about environmental weather damage.
ETFE Foil Benefits
Obviously the main benefit of using this material is the high quality insulation it offers, but there are a number of other advantages to having ETFE foil installed in your home. As the material is transparent you will find that the room has an increase in the natural light transmission, which will lead to a reduction in the need for artificial lighting within the room. Less artificial lighting means less electricity and as a result reduced energy bills.
This material is very environmentally friendly, and is 100% recyclable. The outside of the foil is self adhesive meaning it cleans itself every time it rains. ETFE foil has a considerably longer life span than traditional roofing materials, and the aluminium support makes it very durable.
If you are seriously considering utilising this material in your home then I recommend you buy ETFE at the Vector Foiltec website, as they have over twenty five years experience working with the foil.
