Construction and Materials
DuPont Performance Building Solutions offers a range of weatherization products designed to enhance the performance and durability of building envelopes. These products are engineered to provide effective air and water barrier solutions, flashing, specialized tapes, and rainscreen systems.
Construction and Materials
- Air & Water Barriers: These systems are typically constructed from advanced polymeric materials, often incorporating multi-layer technologies. The specific composition is designed to create a continuous barrier that prevents the ingress of liquid water and air while allowing water vapor to escape, promoting breathability and preventing moisture buildup within wall assemblies.
- Flashing: DuPont's flashing products are engineered for superior adhesion and conformability to various building substrates. They are often made from durable, self-adhered materials that form a robust seal around windows, doors, and other penetrations, effectively preventing water intrusion. The materials are chosen for their resistance to UV exposure, temperature fluctuations, and mechanical stress.
- Tape: The weatherization tapes are manufactured with specialized adhesives that provide long-lasting bonds to a variety of building materials, including sheathing, housewrap, and flashing. These tapes are designed to create airtight and watertight seals when used to join seams and cover fasteners, contributing to the overall integrity of the building envelope. The adhesive formulations are optimized for performance across a wide range of environmental conditions.
- Rainscreen Systems: DuPont's rainscreen solutions typically involve creating a ventilated air gap behind the exterior cladding. This construction method utilizes specialized materials to facilitate drainage and airflow. The system components work together to manage moisture by allowing water that penetrates the cladding to drain away and promoting drying through ventilation. The materials used in these systems are chosen for their durability and ability to withstand exterior environmental exposure.

Product Summary
JM Ice and Water Guard™ is a self-adhering membrane composed of rubberized asphalt roofing sheet with a strong inorganic glass mat for reinforcement. SureGrip™ is used under shingles, slate, shakes and tiles. It prevents leaks and damage to decking and internal structures from wind blown rain and water backup due to ice dams. SureGrip™ is also used as a vapor barrier for roofs, walls and floors.
Construction and Materials
Johns Manville offers a range of high-quality weatherization and flashing products designed to protect your building envelope from the elements. These products primarily function as ice and water barriers, crucial for preventing moisture intrusion and the associated damage that can occur, especially in challenging weather conditions.
The construction of Johns Manville's ice and water barrier products typically involves a robust, multi-layer system engineered for superior performance and durability. While specific construction details can vary slightly between product lines, the core principles remain consistent:
- Reinforced Membrane: A key component is a specially designed membrane that forms the primary barrier against water penetration. This membrane is often reinforced to enhance its strength, tear resistance, and ability to conform to roof deck irregularities.
- Adhesive Layer: A critical feature is the self-adhering capability. This layer allows the product to securely bond directly to the roof deck or other underlayments, creating a continuous waterproof seal without the need for fasteners that could create potential leak points. The adhesive is formulated for excellent adhesion in a wide range of temperatures.
- Surface Treatments: The top surface of the membrane may incorporate features to enhance grip and workability, such as a slip-resistant texture. The bottom surface is protected by a release liner that is removed just prior to installation.
The materials utilized in the construction of Johns Manville's ice and water barriers are selected for their resilience, performance, and long-term effectiveness:
- Polymer-Modified Asphalt: This is a primary material used for its excellent waterproofing properties and flexibility. It provides a reliable barrier against both liquid water and ice dams.
- Polyester or Fiberglass Reinforcement: High-strength reinforcement fabrics, such as polyester mats or fiberglass scrim, are incorporated into the asphaltic layer. This reinforcement significantly improves the product's tensile strength, dimensional stability, and resistance to puncture and tearing.
- Release Liner: A silicone-coated paper or plastic film serves as the release liner. This material protects the aggressive adhesive layer during storage and handling and is easily removed during application.
- Granulation or Surfacing: Some products may feature a granular surface for enhanced UV protection and to provide a suitable substrate for subsequent roofing materials.
These carefully selected materials and robust construction methods ensure that Johns Manville's ice and water barriers provide an essential layer of protection against moisture damage, contributing to the longevity and integrity of the building's roof system.
