    To all concerned,

    The use of side blocks for Tubelite’s 400 Series Curtain Wall is unnecessary for it to function as intended and is not included in standard pricing. Glass shift has not been observed, either in the field, or in laboratory testing. We do not object to them being used if the client wishes to add them.

    Because all projects are unique in their requirements conditions may exist that would justify their use. We do not object to them being used if the client wishes to add them - such as shop-glazing a system, or shifting due to anticipated seismic events.

    There are two options from 400TU curtain wall, P4628 (EPDM) or P4629 (silicone). These options could be adapted to the 400SS curtain wall. For other 400 Series systems, consult the installation instructions for these components.

    Best regards,

    Gerard Schoeb
    Structural and Application Engineering Supervisor
