SuperRib PU Foam & Foil

SENGDEK® SuperRib Pu Foam & Foil

SENGDEK® SuperRib PU Foam & Foil is a completely insulated roofing panel and designed to counter tropical weather in Southeast Asia or other climates. It has a completed insulation system made up of 3 layers, consisting of a layer of rigid polyurethane (PU) foam in between an exterior profiled metal roofing sheet and interior fire retardant PVC paper or aluminium foil. These insulated roof panels are outstanding at high insulation characteristics and its light weight.

SENGDEK® SuperRib PU Foam & Foil contains water resistant materials as it is processed using high density Closed Cell Polyurethane which will not be damaged by rain water. It also eliminates unnecessary multiple construction of processes of laying insulations and roofing sheets into one-off fast and easy way of installation course, thus saving cost in installation and purchasing.

SENGDEK® SuperRib Pu Foam can be transformed into Crimp Curve

Product Features and Benefits :

Light weight & high heat insulation
Good in sound absorption & water resistant
Long spanning capacity with custom-made-length
Savings in cost of purchasing and installation

Closed Cell (Rigid) VS Opened Cell (Semi Rigid) Polyurethance Foam
Closed Cell	Opened Cell
Heat and sound insulator Insulation is based on the closed cell content of foam. The higher the closed cell content, the higher the insulation. The ideal closed cell content is >90% a presented by rigid foam. Rigid foam is suitable to be used as insulator for refrigerator, freezer, sound proof partition and thermal pot. One inch rigid foam able to block at least 70% of heat.	Heat and sound insulator Semi rigid foam has higher opened cell content than closed cell. The heat and sound can pass through the foam easily.
Compressive Strength Closed cell has stronger cell wall. The cell wall gives the strength to the foam. One square inch foam able to withstand 15kg of load. Easy to screw on a surface and difficult to tear off.	Compressive Strength Opened cell does not provide even strength to the cell. Subsequently has very low compressive strength. Difficult to screw on a surface because of soft foam.
Water absorption Closed cell foam does not absorb water. Help to prevent leakage	Water absorption Absorb water easily like a sponge. The water trapped increases the foam weight and easily tear off from surface.
Lifespan In terms of insulation, rigid foam has a long lifespan(>20years).	Lifespan The oxygen can enter foam easily and accelerate the oxidation (aging) of the foam. The insulation property is deteriorating and foam turns powdery.
