Thermal Testing of Polycarbonate Windows for Local Manufacturer

May 14, 2017

The objective of this project was to compare and evaluate the thermal performance of two samples of a polycarbonate glazing, which behave similarly to Insulated Glass Units (IGU), provided by a local window manufacturer to the Building Envelope Technology Access Centre (BETAC) at Red River College.

Research and Services Provided

  • BETAC used the Red River College’s dual environmental chambers in the Centre for Applied Research in Sustainable Infrastructure lab (CARSI) to compare the thermal performance of the two samples using a benchmark from a material with a known thermal resistance.
  • The polycarbonate samples each had different thicknesses, and heat flux sensors were used to measure the thermal transfer across the samples under a set temperature differential, which followed a specific ASTM Standard.


Results of this test can be used for further research and development of the manufacturer’s products.
