Single Ply Systems


For those not familiar with them, a Singly Ply System is a class of commercial roofing membranes commonly described as “single-ply,” or flexible sheets of compounded synthetic materials which are manufactured in a factory to very strict quality control requirements.

Single ply roof systems provide strength, flexibility, and long-lasting durability.  Again, perhaps the greatest of this commercial roofing system is the use of pre-fabricated sheets which are the consistency of the quality of the products are manufactured, have the versatility in their attachment methods, and therefore, a broader applicability.

The Hy-Crown Advantage…

Hy-Crowns single-ply system is extra tough because it is manufactured with Hypalon®, a synthetic rubber made by Dupont. Hypalon® is one of the most durable materials in the single-ply roofing market and has a track record of more than 30 years. Many architects, builders, plant engineers, and commercial roofing contractors rely on Hypalon® roofing systems such as Hy-Crown for reliable, leak free commercial and industrial applications.

Improves with Age

A Hy-Crown roof actually becomes stronger with age because the installed Hypalon material vulcanizes when exposed to moisture and ultraviolet light. An additional benefit is that Hy-Crown has no plasticizers, so the roof won’t shrink or become brittle.

Resists Chemical Attack
Hy-Crown’s Hypalon material gives your Ohio roof solid, long-term protection from pollutants that can attack the surface of a commercial or industrial roof. Hy- Crown stands up to:

  • Vegetable oils (common on restaurant roofs)
  • ASTM No. 1 oil (common around refineries
  • Glycols (a by-product of air conditioners)
  • Acid rain
  • Many fertilizers

Superior Seam Strength
Seams on a Hy-Crown roof can be heat-welded or solvent-welded. The resulting bond is up to six times stronger than the seams of an EPDM roofing system. Your chances of seam failure (and resulting leaks) are greatly reduced with a Hy-Crown job.

Reinforced For Toughness
Hy-Crown consists of a 45 mil Hypalon membrane reinforced with a 10 by 10 polyester scrim fabric embedded in the material. This produces a strong roofing membrane that resists tears and abrasions.

Energy Efficient
You can cut your air conditioning costs by installing a white reflective Hy-Crown roof. Tests show that the surface temperature of a white roof rose only 4 degrees during a sunny 85 degree summer day. The surface temperature of a black roof rose 42 degrees under the same conditions.

Lightens The Load
Because Hy-Crown is mechanically fastened, it doesn’t need heavy ballast that some other single-ply systems require. Your weight is reduced from 10-15 pounds per square foot to less than 1 pound per square foot. That’s less stress on the overall roof structure.
