isolerglass

Isolerglass is a silica-based glass designed for enhanced thermal and acoustic insulation. It combines multilayer glazing with nanoporous silica interlayers and low-emissivity coatings to reduce heat transfer while preserving light transmission. The term is used by manufacturers for advanced insulating glazing products, not a single material.

Composition and structure: An isolerglass unit typically has two or more glass panes separated by a spacer and sealed to form an airtight interspace. The cavity may be filled with inert gas such as argon, and may include a nanoporous or micro-porous interlayer to decrease thermal conductance while improving sound attenuation.

Manufacturing: Production uses standard glass fabrication followed by lamination, coating, and precision sealing. Interlayers are created by sol-gel processes or similar methods, and low-emissivity coatings are applied by sputtering or chemical vapor deposition. Quality checks include leak testing and spectral performance verification.

Properties: Isolerglass units exhibit lower U-values than conventional insulated glass, with improved solar control and acoustic insulation. Visible light transmission is maintained, while edge seals and spacers influence long-term durability and thermal performance.

Applications: Primary use is in energy-efficient building envelopes, skylights, and curtain walls. Some products are marketed for retrofits where enhanced insulation is desired without sacrificing daylight.

History and terminology: The concept reflects advances in glass laminates, porous materials, and coatings. The name isolerglass is not standardized; different manufacturers may describe similar products as isolerglass, nanoporous-glass glazing, or high-performance IGUs. Related technologies include insulating glass units, low-emissivity glass, and vacuum-insulated glazing.
