Lead bay roofs are even more expensive starting from 300 per m2.
Etfe roof cost per m2.
Flat roof replacement costs.
One made with single glazing 15 kg m 2.
High performance rubber profiled roof pitched standing seam appearance 75 120 m 2.
High density polyethylene hdpe.
Green roofs have higher capital costs than traditional ones particularly when allowance is made for the additional structural loads.
High performance liquid applied membrane 850 1100 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.
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.
A roof constructed with double glazing weighs 30 kg m 2.
Air cushion roof etfe type roof fibresheet roofing.
Etfe foils have a very high durability compared to other transparent plastic materials.
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.
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.
Flat roof prices start from 40 per m2 for felt roofs.
Vinyl coated polyester pvc.
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.
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.
Relatively more perimeter can significantly increase the overall rate per m 2.
This compares with about 0 1 kg m2 for a roof made from etfe.
Etfe is a very ductile material and demonstrates good failure behaviour thanks to its large deformations before breaking point.
Corrugated fibre cement 30 40 m 2.
Rubber roofs costs start from 80 per m2.
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.
Maintenance costs are also higher.
