  • RE: Should flashing be used under storefront?


    To all concerned,

    Storefront and curtain wall drain water differently. Storefront drains water down the vertical mullions to the sub-sill or sill flashing. Tubelite storefronts are designed to be used with our extruded and thermally broken sub-sills, and do not require brake metal flashing.

    Tubelite considers the use of flashing beneath storefront products as un-necessary. All storefront systems are tested for air, water, structural, and thermal performance without sill flashing; and thus, it is not considered necessary to meet performance requirements. Flashing, when included, should be considered as part of the surrounding condition for aesthetics or function, and should be carefully detailed and integrated to the storefront system to prevent compromising the system’s performance.

    Best regards,
