| FEATURES | BENEFITS |
| Fully welded and assembled | • saves installation time and money • no chance of missing parts • no field assembly required |
| Factory insulated | • alleviates the co-ordination problem of providing insulation for roof curbs by either the mechanical contractor or the roofer. This problem is rarely addressed and roof curbs go uninsulated causing condensation problems. |
| Pitched to match roof configuration | • allows equipment to stay level • saves installation time and money by eliminating shimming • provides uniform loading surface unlike shimmed curbs which rely on point loading |
| Designed to meet roofing system | • proper curb style matches roof system
and eliminates leak situations • eliminates costs by preventing roofer from having to alter curb to meet design requirements |
| All roof curbs delivered at the same time | • eliminates any delay in project • all curbs mounted at one time |
| Single source responsibility | • one contractor to co-ordinate and install all curbs |
| One specification required | • saves time and money • eliminates confusion in trades |
| Curb uniformity | • all curbs same style, height, and proper pitch |
| Dollar savings | • reduce multiple markups • helps keep projects within budget |
