Extreme Weather Protection
The Windsor provides a durable barrier against extreme weather, receiving the UL 2218 Class 4 Impact Resistance classification, the highest rating possible. In a Class 4 rating test, the Windsor withstood a simulation of hailstones impacting a roof at 90 mph (144 kph) without sustaining damage.
Malarkeys revolutionary Windsor shingle technology begins with a durable base layer of fiberglass mat. Malarkeys unique fiberglass mat is coated on both sides with the SBS modified rubber asphalt which provides tensile strength and increased flexibility, protecting your investment.
SBS Modified Asphalt
The rubberizing aspect of SBS increases flexibility and weatherability for your roof. The thermo cycling resilience of SBS modified asphalt provides greater granule adhesion for the shingle to create a better barrier from the elements. When granules stay on the shingles, your roof lasts longer.
Rain Seal Protection
Malarkeys Windsor shingle is manufactured with SEBS asphalt rain seal protection. The SEBS asphalt has elongation capabilities of up to 800 percent, making it flexible down to zero degrees. The rain seal remains intact through the freeze and thaw cycle. Malarkey SEBS asphalt adhesive is superior to oxidized asphalt because of its cohesive and adhesive properties. The adhesive properties of SEBS asphalt join the shingle together while the cohesive properties prevent it from breaking apart from itself.
