  • Sizes and Item Codes
    Roll Sizes – Sq Ft Roll Item Code
    4’11” x 164’ – 807 I07001
  • Problem

    Open-joint cladding systems require extreme water and vapor protection. If the water-resistive barrier is not durable in extreme weather, or stable when exposed to prolonged periods of UV light, the system will fail.

  • Solution

    DELTA®-FASSADE S is the water-resistive barrier that is ideal for open cladding. The watertight membrane is highly vapor permeable and extremely tear resistant. Highly stabilized against damage from UV exposure, the barrier is designed for use in cladding systems that have open joints up to 2” (50 mm) wide, which expose up to 40% of the entire façade surface.

    DELTA®-FASSADE S is the only UV-stable, water-resistive barrier that is tested under and has passed ICC-AC38.

DELTA products, DELTA-DRY

DELTA®-DRY

Rainscreen

  • Structured membrane provides two-sided exterior and interior drainage and ventilation
  • Ventilated air space allows interior water vapor to escape between the sheathing board and the membrane while minimizing condensation that could cause potential damage within the building enclosure
  • Complete capillary break behind the cladding provides ventilation, which captures and drains transient moisture migrating through the wall structure
  • Waterproof, resisting the passage of bulk water from wind-driven rain and snow, and managing water leakage through the cladding
  • Installed outboard of the water-resistive barrier over sheathing board
  • Material is easily cut, and seams are simply butted together, making overlapping unnecessary
  • Exterior cladding material can be installed as usual, right on top of the rainscreen
  • Sizes and Item Codes
    Roll Sizes – Sq Ft/Roll Item Code
    3’3″ x 50′  –  164 I01001
  • Problem

    Without proper ventilation and drainage, moisture can accumulate between the water-resistive barrier and siding of a building. This issue can be particularly evident with absorptive or reservoir claddings. A rainscreen separates the cladding from the building, allowing drainage and moisture evaporation.

  • Solution

    DELTA®-DRY is an innovative ventilated rainscreen for complete moisture protection. It is the ideal protection behind adhered manufactured stone veneer, conventional stucco and other absorptive claddings.

DELTA®-DRY STUCCO & STONE

Rainscreen

  • Structured membrane provides two-sided exterior and interior drainage and ventilation
  • Pre-installed polypropylene fabric mortar screen prevents scratch coats from filling its dimple structure
  • Ventilated air space allows interior water vapor to escape between the sheathing board and the membrane while minimizing condensation that could cause potential damage within the building enclosure
  • Material is easily cut with a utility knife, and seams are simply butted together, making overlapping unnecessary
  • Sizes and Item Codes
    Roll Sizes – Sq Ft Roll Item Code
    3′ x 46′ – 151 I01002
  • Problem

    Without proper ventilation and drainage, moisture can accumulate between the water-resistive barrier and siding of a building. A rainscreen separates the cladding from the building, allowing drainage and moisture evaporation.

    Stucco and stone claddings require specialized moisture control. Absorptive claddings increase the risk of solar-driven moisture, which puts wood substrates at high risk of water damage. A properly installed rainscreen allows for separation and drainage to dry out these problem areas.

  • Solution

    DELTA®-DRY STUCCO & STONE is a ventilated rainscreen with a factory pre-installed mortar screen that reduces scratch coat mortar consumption. Air-gaps on the interior and exterior side of the membrane make DELTA®-DRY STUCCO & STONE the ideal protection behind adhered manufactured stone veneer and conventional stucco.

    6′ x 65’7″ – 394 I05003
    6’7″ x 65’7″ – 430 I05004
    7′ x 65’7″ – 459 I05005
    8′ x 65’7″ – 527 I05007
    9’10” x 65’7″ – 645 I05009
  • Problem

    Without proper moisture protection, you risk possible damage and hazards from mold and mildew buildup. Protecting your foundations from water and moisture is critical.

  • Solution

    DELTA®-MS is a dimpled membrane that uses our exclusive Air-gap Technology to ensure your basements stay dry and last longer. The vacuum-formed dimpled pattern creates an air gap between the membrane and the foundation, allowing water to drain. By keeping water away from the foundation wall, DELTA®-MS is able to keep basements permanently dry and protected. Unlike sprays, which crack when concrete walls crack, it bridges cracks so no water intrusions can occur. This damp proofing helps ensure more comfortable and healthier living spaces for your homeowners; better efficiency and durability for your buildings; and fewer warranty claims and call-backs for you.

    Unlike sprays, DELTA®-MS doesn’t require specialized safety equipment and you don’t have to wait around for the concrete to cure or the fumes to dissipate so installation can be faster, easier, and more cost effective. The extensive DELTA® Academy Certified-Installer Program helps ensure materials are properly applied, allowing you to provide an industry-leading warranty.

DELTA products, DELTA-FOOTING BARRIER

DELTA®-FOOTING BARRIER

Foundation

  • Composed of polyester needle-punched fabric, a polyethylene barrier, and an anti-slip surface layer
  • Easy installation – lay it into the freshly poured concrete footings, smooth into place with a trowel, and form the keyway with the membrane in place
  • Sizes and Item Codes
    Roll Sizes – Sq Ft Roll Item Code
    17.7″ x 82′ I03001
  • Problem

    Often the footings of a building are not properly sealed. The capillary rise of water through the porous cement footing and into the interior of the structure can allow for mold growth, deterioration of moisture-sensitive materials, and unhealthy living conditions.

  • Solution

    DELTA®-FOOTING BARRIER acts as a physical barrier between the footing and the foundation wall, resisting the capillary wicking of water and upward migration of moisture from the footings into the foundation wall, also known as rising damp.

DELTA®-FL

Basement Floor

  • Installed dimple side down, a ventilated air space is created above the slab, allowing equalization of water vapor pressure
  • Seams are simply taped with DELTA®-MOISTURE PROOF TAPE to ensure that moisture cannot migrate inwards through the joint areas
  • DELTA®-FL topped with plywood sheets will allow a variety of floor coverings to be installed: carpeting with underlay, vinyl flooring, hardwood flooring
  • Laminate floors can be directly laid on top of the membrane
  • Provides a reliable capillary break and vapor barrier, ensuring a dry, livable basement
  • Sizes and Item Codes
    Roll Sizes Item Code
    4’9″ x 68’6″ – 328 I02001
    3’6″ x 30′ – 105 I02002
  • Problem

    To turn your basement into a usable, livable space, proper moisture protection is necessary. Moisture barriers are often installed only on the walls of a basement and not the footing. Moisture diffuses from the high area of concentration of the soil, to the low area of concentration in the basement.

  • Solution

    DELTA®-FL is a dimpled, heavy-duty, gray plastic membrane for concrete and slab-on-grade floors that helps to keep moisture out of your basement. The membrane provides a significantly more comfortable floor.

    DELTA®-FL protects sensitive materials by providing a reliable capillary break and vapor barrier. In a conventional basement, dry air in the living space acts as a “magnet” for water vapor migrating up through the concrete. The air gap created by DELTA®-FL allows the water vapor pressure above and below the concrete slab to equalize, while preventing the moisture from migrating further inwards. Hence, moisture does not affect the flooring material and your basement area stays dry and comfortable. The membrane also provides a thermal break, which increases the comfort in your basement and makes the floor feel warmer.

  • Accessories

    DELTA®-MOISTURE PROOF TAPE

    Adhesive tape for sealing of DELTA®-FL joints. Helps to prevent moisture rise from concrete floor. 2.36″ x 108’3″ per roll.
