Access doors - Series 3000
PRETAL access doors series 3000 are designed for a surface installation. They are generally called roof access doors. Two models are available PTL3015 for roof access and PTL3020 for drinking water well.
The frame is fabricated from aluminum AL (11ga) or galvanized steel GS (14ga), which includes a foil-faced polyisocyanurate foam sheathing of 50mm with insulation factor R14. The leaf is fabricated in the same manner. Because these doors are surface mounted and are applied to light duty loads (more than sufficient for snow loads), their applications are different than the series 1000 and 2000 doors.
The construction of the series 3000 doors allows to vary from
a single leaf to double, face-to-face, leaf. However, they offer
all the same options as the other series.
