Şişecam Climax and triple Isıcam S3+: coated glass is not a finished insulating unit

The short answer

Şişecam Climax is a low-emissivity/solar-control coated glass product. Isıcam S3+ is a triple insulating glass unit. One is a glass pane; the other is an assembled unit with cavities, spacers and edge seals. Thermal and optical performance depends on the full composition, coating position, spacer, gas fill, dimensions and frame.

Two different product levels

The Climax catalogue describes coated flat glass. The Isıcam S-series catalogue describes insulating-glass systems, including the triple S3+ option. A low-E pane may be part of a triple unit, but one should not assume a particular Climax variant or pane position for every S3+ configuration. The fabricator’s project-approved specification must define the glass sequence and coating surfaces.

Specify the entire glazed unit

For comparison, request the exact glass types and thicknesses, coating name and surface position, cavity widths and gas fill, spacer, edge seal, finished dimensions and calculated thermal and optical values. Whole-window performance also depends on frame, size and installation junctions. Do not copy a U-value from another project with a different make-up. Şişecam’s façade guide gives general design recommendations; it does not replace a calculation for the selected combination. “S3+” alone is not enough to determine a U-value or sound rating.

Procurement checks

The order should state every pane, coating and position; dimensions; spacer and gas; safety-glass requirements; edgework; cut-outs; labels; packaging; breakage reporting; freight and unloading. After production approval, record all changes in writing. The designer and glass processor should confirm thermal, structural and safety requirements. The specifier checklist includes document and delivery fields.

Source and limits

Şişecam catalogues were checked on 23 September 2026. We do not claim a specific Climax T configuration, pane position or U-value without an exact documented make-up. The illustration is a generic triple-unit diagram, not a manufacturer-approved configuration.

Check appearance as well as energy data

Low-E or solar-control coatings can affect light transmission, external reflection and colour perception. These properties depend on the coating type, pane order and viewing direction. Where appearance is important, review a sample or manufacturer visualisation for the exact make-up rather than relying on a product-family name. Glass size and the façade’s light conditions can affect how the unit is perceived.

The same glazing recipe may not suit every orientation or climate exposure. Ask the designer to state the conditions and dimensions used for the calculated U-value. Depending on the brief, solar-energy transmittance, visible-light transmittance, safety classification and acoustic performance may also need to be assessed for the complete unit. These are specification checks, not properties implied by “S3+” alone.
