Etfe has high level heat retention which when combined with its ability to allow in more natural light than glass can reduce energy costs by around 30 compared to glass ref 14.
Etfe roof cost per m2.
A roof constructed with double glazing weighs 30 kg m 2.
Relatively more perimeter can significantly increase the overall rate per m 2.
Air cushion roof etfe type roof fibresheet roofing.
Extra over cost for transparent grp sheeting to match 20 30 m 2.
The swiss architecture team of jacques herzog and pierre de meuron created a sculpted look for the allianz arena 2005 one of the most beautiful etfe structures in münchen.
Green roofs have higher capital costs than traditional ones particularly when allowance is made for the additional structural loads.
Etfe foils have a very high durability compared to other transparent plastic materials.
Vinyl coated polyester pvc.
This compares with about 0 1 kg m2 for a roof made from etfe.
The exact material you use will have an impact on the cost of the roof with basic felt solutions costing around 50 per square metre for the material itself and more high end materials such as modern grp a form of fibreglass going up to 90 per square metre but allowing unlimited options in terms of colour and generally being more long lasting.
Flat roof cost per square metre.
Corrugated fibre cement 30 40 m 2.
As a result etfe roofs need far less structural support which makes it particularly useful in atria that need lots of light.
Lead bay roofs are even more expensive starting from 300 per m2.
Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point.
The ratio between the perimeter and the roof area is an important measure when pricing.
High tensile strength extraordinary tear and impact strength of etfe foil are the basic properties of an ideal membrane material.
Etfe is generally utilised in a cushion system which enhances the insulation properties of the material whilst still providing good translucency.
High performance liquid applied membrane 850 1100 m 2.
For fibreglass expect to pay from 90 per m2 and for fire glass bay roof from 250 per square metre.
Rubber roofs costs start from 80 per m2.
High performance rubber profiled roof pitched standing seam appearance 75 120 m 2.
High density polyethylene hdpe.
There is a large variable in cost per square foot because the more steel you use on a tensile structure frame supported vs a mast supported the more expensive it will be.
Flat roof replacement costs.
Flat roof prices start from 40 per m2 for felt roofs.
