At B.F. Rich, we are committed to using the most advanced insulation technologies available for our windows, keeping our customers more comfortable, and saving them money. We use Warm Edge DuraSeal™, Argon gas fills, to produce the warmest windows on the market.

Patent pending DuraSeal™ design incorporates unique materials and a breakthrough in continuous composite manufacturing processes. This advanced technology offers a higher performance spacer system at a competitive price. DuraSeal™ takes optimum advantage of laminates and adhesives to reduce thermal conductivity while improving surface and corner appearance over other flexible spacers. This multi-layered spacer system featuring specialized components results in superior window performance and aesthetics over other warm edge spacers.

A - Spacer Subassembly –unique multi-component spacer which is bendable yet incompressible and stable.
B - Bondline Adhesive –proprietary high performance adhesive providing exceptional resistance to gas and moisture vapor transmission.
C - Desiccated Topcoat –desiccant concentrated in the top layer provides rapid dew point suppression.

Traditionally, the space between glazing was flushed with dry nitrogen just prior to sealing. Filling the space with a less conductive, more viscous or slow-moving gas like argon minimizes the convection currents, and the overall transfer of heat between the inside and outside is reduced. Using argon gas fills measurably improves thermal performance.

B.F. Rich Applications:
Argon gas fill is available as an option in all B.F. Rich's vinyl window systems. Argon gas filling is done with our Quik-Dose™ (Fig.1) equipment assuring you of the highest gas fill for the best energy savings.

A spark light is then used to measure the gas fill percentage in an insulated glass unit. (Fig. 2)

The chart below shows generic thermal performance increase with gas fills.
