Air & Water Resistance

Blink® Blinds + Glass products protect against moisture and air infiltration in two areas:

Infiltration into the insulated glass air space through the glass seal.

Infiltration from the outside that attempts to penetrate the frame seals against the door and the glass (applicable to Blink units installed in ODL frames).

Infiltration that Attempts to Penetrate the Insulated Glass Air Space through the Glass Seal

Blink insulated glass units with built-in blinds include premium components that enable certification by the Insulating Glass Certification Council (IGCC) as meeting the requirements of ASTM E 2190. ASTM E 2190 is a harmonized standard test protocol adopted by the U.S. and Canada for evaluating insulating glass (IG) performance, durability, and longevity. There are three main parts to the standard:

The High Humidity Test subjects samples to high humidity and temperature with the objective of forcing moisture into the sealed air space in an IG unit. Specimens are tested for 42 days and subjected to 95% ±5% relative humidity.

Accelerated Weather Cycling simulates weather cycling from hot to cold extremes with moisture added during the hot cycle. Specimens are tested for 63 days and subjected to 252 cycles.

The Volatile Fog Test shows that components, or trapped impurities, will not out-gas a volatile fog, which could result in a deposit on the interior glass surface. No fog must be visible at arm's length.

(Blink units installed in ODL frames)

Some Blink units are installed in ODL frames. All ODL door glass products are tested to assure they protect against water and air infiltration in accordance with industry standards.

Test results for Blink units installed in ODL frames are shown in the chart below.
