PIR Drywall Construction Technology
PIR (Polyisocyanurate) is a superior form of rigid polyurethane technology, with significantly higher benefits of fire retardance, thermal and sustainability. It has been validated and certified by BMTPC under PAC No. 1039-S/2018, issue no. 1, Date of issue: 30-08-2018 and renewed on 10-02-2020.
PIR dry wall panel system is almost 8 times lighter than conventional brick-mortar walls. They are sandwich panels, which are composed of Fiber Cement Board (CFB)/ metal sheets/ oriented strand board/ gypsum board as facing on one or both sides with PIR foam as filling material. The panels can be used as internal/external partitions (and walls) and also for roofing solutions. This technology is suitable of single as well as multi storey buildings.
Benefits of PIR technology are as follows:
||IS 11239 part 12
||NO INGRESS THROUGH PIR
|PIR-CFB Panels provide very high thermal insulation, having K-factor = 0.0326 as per ASTM C 177
Reduced Cement, Sand, RCC and Water Consumption
Easy Transportation & Installation
Reduced Carbon Footprint
Extending support to affordable housing, Covestro has developed house models based on PIR technology which can be erected quickly and can withstand high wind speeds. In agreement with varied stakeholders, Covestro inaugurated a model of a G+3 L.I.G. building in Jaipur for Rajasthan Housing Board (RHB). This is a fully insulated building.
COSTING: Cost will depend on various factors, like soil, building type and specifications. Roughly, the cost is approximately Rs.1150 / sqft.
