Lead bay roofs are even more expensive starting from 300 per m2.
Etfe roof cost per m2.
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.
Extra over cost for transparent grp sheeting to match 20 30 m 2.
A photo journey of etfe architecture quickly dispels the notion that this is a simple plastic cladding material you might put over your roof or boat on a rainy day.
Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point.
Flat roof prices start from 40 per m2 for felt roofs.
This compares with about 0 1 kg m2 for a roof made from etfe.
The ratio between the perimeter and the roof area is an important measure when pricing.
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.
Relatively more perimeter can significantly increase the overall rate per m 2.
One made with single glazing 15 kg m 2.
Flat roof replacement costs.
High performance liquid applied membrane 850 1100 m 2.
Corrugated fibre cement 30 40 m 2.
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.
Rubber roofs costs start from 80 per m2.
High performance rubber profiled roof pitched standing seam appearance 75 120 m 2.
Air cushion roof etfe type roof fibresheet roofing.
High density polyethylene hdpe.
For fibreglass expect to pay from 90 per m2 and for fire glass bay roof from 250 per square metre.
Flat roof cost per square metre.
As a result etfe roofs need far less structural support which makes it particularly useful in atria that need lots of light.
Green roofs have higher capital costs than traditional ones particularly when allowance is made for the additional structural loads.
Vinyl coated polyester pvc.
Maintenance costs are also higher.
Etfe foils have a very high durability compared to other transparent plastic materials.
A roof constructed with double glazing weighs 30 kg m 2.
