CAVITY WALL INSULATION:

Providing and fixing wall insulation treatment with 50 mm thick Insuboard (XPS) Extruded Polystyrene Board, having thermal conductivity of 0.028 W/m.K, density 34-36 Kg/mtr.cub, compressive strength of > 300 kPa, water absorption of 0.2 % by volume,   B2 grade fire compliance, in the size of 600mm width x 1250 mm Length x 50 mm thick: square edge / shiplap  boards fixed in brick pattern: staggered joints with the help of mechanical fasteners & No More Nail adhesive of Bostik. After fixing Insuboard, leaving an air gap of 25 mm and building second brick wall final finishing as directed by the Engineer In Charge as per the details below.

APPLICATION METHODOLOGY

  • Supplying & application of 50 mm thick Insuboard (XPS), Extruded Polystyrene Board, 34-36 kg/m3 density, > 300 kpa compressive strength & thermal conductivity 0.028 w/m.k, of size 600 mm x 1.25 mtr.
  • Insuboard is to be installed on internal  side of external wall with the help of screws/ fasteners on all the four corners. One screw / fastener at each corner.​
  • After that leaving an air gap of 25mm, building another brick wall, as final finish.

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 & 50 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 as per the instructions of Engineer in charge complete in all respects etc.

FINISH (OPTIONAL):

Insuboard to be finished with another brick / AC Blocks wall after leaving a gap of 25 mm, as per the instruction of the engineer in charge.

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 sealant, Rockwool sleeves etc wherever there are electrical cut outs & opening. The boards must be of self extinguishing characteristic etc.

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 .
