MATERIAL - GENERAL DESCRIPTION:

Extruded Polystyrene boards to be manufactured from General Purpose polystyrene granules though an automated extrusion process free of CFC blowing agents : preferably with a blend of co2 & ethanol : low Global warming index : the boards are 100 % closed cell structure with a unique properties of high compressive strength & a stable thermal conductivity properties over the life cycle of building etc.

APPROVED SYSTEM:

The boards of size 600mm width x 1250 mm length & 75 mm thickness with square edge to be laid in brick patterns with the help of suitable bituminous vapour barrier or No more nail adhesive & mechanical fasteners of appropriate length with fixtures like rock wool sleeves at cut outs , Fire stop , foam filler  at the perimeter joints & wherever any opening etc are provided. The entire system has to be also protected with a suitable Fire rating improvement coating along with Fibre mesh etc as per the instructions of Engineer in charge complete in all respects etc.

FINISH (OPTIONAL):

Insuboard to be finished with Fibre glass mesh followed by protective coating Insuset 1.5 mm thick with the help of appropriate trowels & levelling tools : the coating improves the Fire rating properties of the over all under deck insulation systems.

THERMAL PERFORMANCE:

The extruded polystyrene under deck insulation system improves the thermal efficiency of the building by reducing the U value as per the prescribed norms in the ECBC codes depending on the type of building  in terms of hours of operations & geographical location. The thermal performance is very stable through out  the life cycle of the building. It improves the thermal comfort & also helps in optimising the loads thereby reducing the capex & operating cost of HVAC systems.

​FIRE PERFORMANCE:

XPS boards must be fully tested in accordance with DIN 4102 part 1 with regard to fire properties, flame spread , & surface burning characteristics . Also suitable Fire stops , sleeves, PU selant, Rockwool sleeves etc wherever there are electrical cut outs & opening. The boards must be of self extinguishing characteristic etc.

PROVISIONS FOR suspended ceiling fixtures etc:

​Suitable provisions & finishing to be provided with the help of can spayed PU wherever the boards are cut  in the ceiling or the perimeter to make the system seamless.

QUALITY ASSURANCE:

​The suspended ceiling system is to be manufactured within a recognized quality management system as per ISO 4898 & ASTM C 576 requirements. Each batch should also have the Raw material GPPS test certificates .
