DOWSIL™ 3364 Warm Edge IG Sealant

  • Overview

    High modulus, two-part silicone secondary sealant with low thermal conductivity for use in energy efficient Insulated Glass Units.

    Enhancing energy performance of glass façades
    Thermally efficient insulating glass joints

    Higher glass surface temperatures
    Reduced risk of internal condensation

    No design change
    Avoid costly design changes and enhance performance

    For warmer buildings and improved living comfort

    DOWSIL™ 3364 Warm Edge IG Sealant is a secondary silicone for insulating glass, with low thermal conductivity and excellent performance. It holds a European approval (ETA), allowing for durable bonding in high performing energy designs.

    Suitable for double and triple glazed IG, including gas-filled units in structural glass façades, this new silicone has a very low thermal conductivity to optimize performance in glass façades for improved energy efficiency and living comfort.

    As with other DOWSIL™ Insulating Glass silicone sealants, it provides long-term durability with UV resistance and excellent adhesion to glass. The low thermal conductivity of DOWSIL™ 3364 Sealant can increase the energy efficiency of a façade and hence the energy performance of the total building as well as help reduce CO2 emissions. This can also result in a reduced risk of condensation on the internal window panes:

    Areas of heat loss in a façade system

    Benefits

    • European technical approval (ETAG 002) for structural glazing with insulating glass
    • No design changes required
    • 45% lower thermal conductivity when compared to conventional IG silicones with a thermal conductivity of λ = 0.35 W/mK
    • Up to 25% lower psi-values for linear thermal transmittance
    • Enhanced energy performance of façades: up to 5% lower UCW-value
    • Lowers risk of condensation: up to +1°C higher surface temperatures

    Applications

    • High performance insulating glass
    • Glass edge of pure glass corners
    • Insulating glass for unitized façades
    • Insulating glass in structural glazing designs
    • Façade Toggle systems

    DOWSIL™ 3364 Warm Edge IG Sealant has been tested according to ETAG 002 and EN 1279.
