Sliding glass patio doors are covered by the same Canadian General Standards Board edge seal standard and the same CSA Standard A440.2 for the Energy Rating system as windows. Other aspects of the sliding door are covered by the CAN/CGSB 82.1 standard. The same technology is used to increase energy efficiency, reduce heat loss and improve condensation resistance. The same high installation standards are necessary for the door to perform to its potential.
It is important to maintain the same standard of thermal performance with regard to all glazed surfaces in any home or building. Therefore it is necessary to apply the same standard to any and all glass doors as is applied to the windows.
