SOLERA® S & R9 Installation Guidelines


Solera-S insulated translucent glazing units (TGUs) are made of two tiles of glass with a high performance
translucent insulating core. The SOLERA® S TGU has a nominal thickness of 2.5 inches plus
interior and exterior glass lite thicknesses, and uses a stainless steel capillary tube vent (not to be crimped) to maintain both pressure and moisture equilibrium within the glazing unit.

The following guidelines have been developed for specification writers, frame manufacturers and
installers to convey the installation requirements of the SOLERA® unit which will ensure satisfactory, long
term performance. It is recommended that this document be read in conjunction with the SOLERA®
Warranty Document, and industry standard recommended practices documented by IGMA. The user is
encouraged to contact Advanced Glazings Ltd. directly for advice on specific glazing installations.


  1. The SOLERA® TGU is manufactured using a wide range of architectural glass types and thicknesses.
    The glass specified for the SOLERA® TGU must be selected by the user to meet project-specific
    objectives as well as national and local building codes.
  2. Frame and sash must accommodate the thickness of the SOLERA® TGU (reference drawing 300-3001-
  3. Framing system must be designed to meet project specific objectives as well as national and local
    building codes.
  4. The unit must be sealed to the building to prevent the migration of moisture into the “intraframe
    cavity” from the building interior (reference drawing 300-3003-12).
  5. Glazing installation must ensure that the “intra-frame cavity” is drained and vented to the
    outside . This helps prevent the build up of high-humidity air, allows for the draining of standing
    water, and ensures pressure equilibrium (reference drawing 300-3005-12). Frame vent holes
    should meet Insulating Glass Manufacturers Alliance ( IGMA’s) recommended minimum size
  6. Manufacturer’s labeling identifies the orientation required (Inner Lite/This End Up). Proper
    orientation ensures that the open end of the stainless steel capillary pressure equalization (vent)
    tube is positioned in a downward direction and located at the top left corner of the unit, as viewed
    from the building interior (see drawing 300-3002-12). Other orientations must be approved by
    the manufacturer in order to maintain warranty coverage. As well, ‘inner lite’ ensures proper
    orientation of inside and outside lites where a difference exists.
  7. The vent tube must be free of any obstructions. SOLERA® S vent tubes must not be crimped, which
    would limit the free flow of air in and out of the vent tube.
  8. Interior and exterior lites must be supported by setting blocks, and spacers must be installed on
    vertical edges to prevent direct contact between glass and frame. Setting blocks and spacers must
    be adequate to prevent direct contact between glass and frame in all circumstances.
  9. The glazing rebate (i.e. clearance between frame and TGU) must be clear of any protrusion except
    for glass support setting blocks or spacer shims. The setting blocks should be designed or
    positioned to allow water passage to the weep or vent holes.
  10. The glazing stops must provide plane, continuous and uniform supports for the surfaces of the
  11. Frame joints must be adequately sealed to prevent water and air infiltration.
  12. Under no circumstances should the edge of the TGU be allowed to sit in water.
  13. Edge clamping pressure must be sufficient to achieve an air and water tight seal but must not
    exceed 10 lbs. per linear inch to avoid risk of unit damage.
  14. Frame members must be structurally designed to withstand the wind loads and dead loads
    transferred by the SOLERA® TGU. Each frame member should be stiff enough not to deflect more
    than the lesser of length/175 or 3/4 “ at full design load. All edges of the sealed unit must be
    supported to resist wind and other loads. The minimum bite on the glass edge should be 13mm
    (½”) to firmly support the insulating glass unit when exposed to static and dynamic loads.
  15. The height of glass stops may vary depending on the area of the TGU, external forces and
    functions. A stop height of approximately 19mm (3/4 inch) is commonly used. The minimum
    bite on the glass edge should be 13mm (½”) to firmly support the insulating glass unit when
    exposed to static and dynamic loads.
  16. The use of structurally adequate thermally broken frames is recommended with the Solera TGU
    to improve energy performance and minimize condensation on interior surfaces in cold weather.
    The thermal stress on the TGU is also reduced when thermally broken frames are used.
  17. Glazing clearances must be sufficient to accommodate manufacturing tolerances in the unit size
    and overall thickness and to ensure that the unit “floats” within the retaining system (reference
    drawing 300-3002-12).
  18. For a complete and finished look, available is a three sided and sill rubber gasket that can be
    purchased with your order. It is sold per linear foot. For installation, run a bead of compatible
    adhesive along the gasket. See document 300-3051-12. Three sided is to be placed on both sides
    and top of TGU and sill gasket is placed along the bottom of the TGU.
