| Duro-Last's Engineering Services Department offers technical support including CAD services, to create a roof customized to each building's specifications. |
|
| The Quality Control Lab performs a variety of standardized tests on all components of the Duro-Last roofing system. |
|
| To ensure quality at the onset, this calender machine distributes PVC film evenly. |
|
| Knitting machines knit a polyester
weft-inserted scrim. |
|
| The laminating machine then bonds the weft-inserted scrim between top and bottom layers of PVC film. |
|
| Quality control is a priority. This employee performs a laminator in-line inspection of a completed section of vinyl roofing membrane. |
|
| Rolls of Duro-Last vinyl roof membrane are re-inspected off the line. |
|
| Five-foot rolls of vinyl roof membrane are prefabricated to a building's exact dimensions as specified by the architect or contractor. |
|
| A fastening tab is welded into the PVC membrane sheet. |
|
| Your order is physically measured and squared-up on the folding floor. |
|
| Folding floor inspectors inspect every factory seam of the Duro-Last roofing system before it leaves the manufacturing facility. |
|
| Custom-made pieces are folded from fastening tab to fastening tab, making installation easier. |
|
| Duro-Last provides you with custom-made accessories for all penetrations and details, made from the smae PVC roof membrane as the deck sheets. |
|
| All pieces are rolled and stretch-wrapped and ready for delivery to the job site. |
|
| Duro-Last's in-house training classes provide contractors with the know-how to install the Duro-Last roofing system. |
