Applications

WDG System 14 can be applied over all roofing substrates and membranes in most cases, without the need for tear off of the old system, provided the old system is in reasonable condition and requires no structural renovation.

List of Substrates

• EPDM roofing membranes.
• uPVC roofing membranes.
• Torch on felt roofing membranes.
• Asphalt.
• Timber substrates.
• Concrete substrates.
• Metal substrates.
• Plastic substrates.
• Asbestos encapsulation.
• Clay tile.
• Green mineral felt is a poor quality roofing membrane, in the case of this material we recommend removal before WDG System 14 is applied.
• WDG System 14 can also be used for external and foundation insulation.
  

• Guaranteed “Leak Proof”
• No Flashings
• No Seams
• No Fasteners
• Highest rated insulating value on the market
• Eliminates thermal bridging and air movement
• Environmentally Friendly & 100&% Sustainable
• Fire rated & approved by UL & FM global 

ENVIRONMENTAL BENEFIT

WDG System 14 offers the consumer piece of mind in the knowledge that they have chosen a product that is not only a high performance system, but also benefits the environment greatly.

FROM START TO FINISH

All the raw materials used in the production process of the roofing foam come from rapidly renewable produce, because the foam it is a once off system, it continues to reduce CO2 emissions indefinitely, unlike the bio-fuels. The raw material which is Soya needed to produce the roofing foam can be sustained on an on going bases as it requires very little to produce the product, there is no ozone depleting potential (ODP) and there are no volatile organic chemicals (VOC's). The Silicone coating used in WDG System 14 roofing is made from recycled EPDM roofing membranes which would otherwise end up in landfill sites taking up to 10,000 years to degrade, the West Development Group call this process R2R (Roof to Roof), it is a 360 degree product, this saves on vast amounts of old rubber membranes wasting away in landfill sites which are already over used. The Silicone is solvent free and contains no VOC's and no ODP. The whole process used to produce both the roofing foam and Silicone coating uses very little energy, the highest temperatures involved are to boil the Soya which is approx 100c, the recycled Silicone is produced using liquid nitrogen, there are no emissions of harmful chemicals, the production process is clean, sustainable and environmentally friendly.

PRODUCTION PROCESS & TRANSPORT OF CONVENTIONAL ROOFING MEMBRANE

Roofing membranes are produced mainly from three kinds of material, modified rubber, uPVC and Bitumen, each of these materials are made from petrochemicals, involving the release of VOC's and ODP's, they are also highly energy intensive, the raw materials used for these products are finite, they are unsustainable as they will inevitably run out over time, before they do they will increase in cost, as a roofing product they also have a finite life span, when they break down they must be replaced, starting the whole process again.
To transport roofing materials from the production process to end use will involve the use of many HGV's, because of there weight, most roofing membranes are made into rolls approx 120cm wide and 12m-15m long, some may be longer, if the average roll contains 18sqm of material, it will take 83 rolls of a membrane to cover a 1,500sqm area, if you include insulation boards which cover approx .72m, you then have to transport 2,083 insulation boards also, some insulating systems require two membranes, some three, not to forget flashing's, collars, fasteners and adhesive.
All that’s required to transport WDG System 14 to cover the same area requires the use of one 360cm by 210cm box van.

COST BENEFIT

In its final application WDG System 14 offers the building owner a high performance roofing system which is sustainable and environmentally friendly. This is achieved through energy savings, reduced maintenance costs and longevity. Renewal of the system only requires a recoat of the Recycled Silicone . Reduced energy costs are achieved through the production process along with the application of the system and the fact that in most cases there is no need for the old membrane to be removed to landfill is what makes the whole system environmentally friendly, and will remain so long into the future. WDG System 14 is truly an environmentally friendly and sustainable product.
