Cambridge® IR with ArmourZone® Performance Shingles


Cambridge IR Shingle swatches and house

Extreme Weather calls for Extreme Weather Protection.

IKO Cambridge IR with ArmourZone performance laminate shingles help resist rain, high wind and blue-green algae growth. Their special 1-1/4” reinforced nailing area (the ArmourZone) ensures incredible fastening power. They’ll help resist nail pull‑through even at high winds and carry a wind limited warranty1 with the use of only four nails.

Among the largest in their class, these shingles are constructed of a fibreglass mat that’s given an extra-thick coating of quality IKO modified asphalt. This makes them heavy-duty yet flexible for superior weather resistance, even in cold weather applications. IKO Cambridge IR shingles have a Class 4 impact resistance rating, which IKO is pleased to present for the sole purpose of enabling homeowners to obtain a discount on their home insurance premiums, if available in their area. (2This rating is not to be construed as any type of express or implied warranty or guarantee of the impact performance of this shingle by the manufacturer, supplier or installer.)
