GlobalRoof Thermal DPP 20|DPP 15


Steel roofing 
Placed Parallel
(can also be considered on a perpendicular position)

GlobalRoof Thermal DPP 20
1. Non-structural Tray HACIERCO C 450.70 with or without perforations (thickness according to span)
2. Insulation (λ = 0,040 W/m.K maximum) 70mm thick (at the bottom of the tray)
3. Airtight vapour barrier
4. Multibeam Purlin under Purlin Cleat (see guide)
5. Insulation (λ = 0,040 W/m.K maxi)100mm thick (unfolded between purlins)
6. Insulation (λ = 0,040 W/m.K maxi) 80mm thick (unfolded between purlins)
7. Glass wool 60mm thick (unfolded and gripped between Purlins)
6. Steel Profile:  HACIERCO
Up = 0,20 W/m².K estimation*
* Value estimated with spacing of purlins of  2,00 m and λ-value Glass wool 0,040 W/m.K maximum 
 Width at load bearing supports for Trays HACIERCO C: 100mm minimum
It is requested to add a complementary insulation to fill the air gap between the panels 

Placed perpendicular
