Material Notes:
QUINN CAST has an optical transparency of 93% light transmission for transparent sheets. It is significantly lighter and much more impact resistant than glass of equivalent thickness. QUINN CAST is resistant to UV rays, shows good thermal stability and low water absorption. QUINN CAST sheets are easy to handle and most fabricating and molding techniques are applicable to it, allowing attractive designs.Construction SkylightsBarrel VaultsPartitionsDoors Industry SignsDisplaysFurnitureSanitary fittingsGift ArticlesShop fittingsSolariumsBoat WindowsProjection ScreensQuinn Manufacturing Group rebranded its Plastics Division as Polycasa in 2013.
