Dear valued Owens Corning® Canada Insulation customer: 

Due to continued increases of diesel fuel costs and freight rates for our transportation, effective on all orders placed on or after May 1, 2026, Owens Corning Canada LP (“Owens Corning”) is implementing a $350 per truckload transportation surcharge across all Canadian zones on all Fiberglas® building insulation products. (pro-rated for less-than-full truck load orders). 

We continue to seek proactive internal actions to mitigate the impact of rising transportation costs. We will review these surcharges periodically as industry conditions change.
