Cat5 weatherproofing membrane

Facts And Information

Cat 5 Protects Your Building Envelope from everyday and extreme weather conditions.

Cat 5 prevents water and air penetration of the building envelope in conditions ranging from everyday weather to Category 5 hurricanes. Cat 5 produces a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU backup walls, and precast concrete.

Cat 5 is a single-component, silyl-terminated polymer (STP) that produces a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU back-up walls, and pre-cast concrete. Cat 5 is proven to prevent water and air penetration of the building envelope in conditions ranging from everyday weather to the drenching rains and 155-mph winds of a Category 5 hurricane.

The Benefits of Cat 5

Why use Cat 5? Here are just a few benefits.

Energy Efficient

The R-Guard air barrier systems stop air leakage through wall structures, rough openings, sheathing seams, and material transitions. This is crucial for an airtight and waterproof building envelope.

Weather Proof

Cat 5™ is proven to prevent water and air penetration of the building envelope in conditions ranging from everyday weather to the drenching rains and 155 mph winds of a Category 5 hurricane.

Completely Waterproof

Cat 5 can be applied in damp conditions and is immediately waterproof, meaning fewer weather delays during construction.

Advantages of Cat 5

Cat 5™ can be applied in unfavorable weather conditions to dry or damp substrates. This feature eliminates many weather-related construction delays and accelerates the “drying in” of new buildings. The durable, elastomeric membrane adheres to most surfaces, is immediately waterproof and is compatible with most sealants and waterproofing or air barrier components.

Features:

  • ICC Evaluation Service Report No. ESR-3416.
  • Silane functional polymer provides superior long term adhesion, crack bridging and weathering
    characteristics. Self seals fastener penetrations.
  • May be spray applied or rolled.
  • Bonds to most common building materials without priming to produce a durable, weatherproof membrane. Easy to repair if damaged.
  • Will not tear or lose effectiveness when exposed to weather during construction.
  • Bonds and cures in wet weather and on damp substrates. May be fully exposed to UV and weather for up to 12 months. If longer, contact for inspection.
  • Single component – saves time.
  • Breathable. Allows damp surfaces to dry.
  • Compatible with most sealants and waterproofing or air barrier components.
  • Solvent free. Isocyanate free. Phthalate free.
  • No shrinkage. No staining.
  • No yellowing.
  • Will not support mold growth.
  • Stops penetration of air and water under normal and extreme weather conditions.
  • Air Barrier Association of America (ABAA) approved product.
