What is an Insulated Glass Unit (IGU)?
Answer: Two or more glass panes with a sealed air or gas space between them
An IGU consists of two or more glass panes separated by a sealed air or inert gas space that provides thermal and acoustic insulation.
Why is argon gas used in double-pane window units?
Answer: To improve thermal insulation because it conducts heat less than air
Argon gas fills the space between panes to improve thermal insulation because it conducts heat less efficiently than regular air.
What causes a failed seal in an IGU?
Answer: Moisture infiltration between the panes
A failed IGU seal allows moisture to infiltrate the sealed air space between the panes, causing persistent fogging or condensation that cannot be cleaned.
What is Low-E glass?
Answer: Glass with a microscopic metallic coating that reflects radiant heat
Low-E glass has a microscopic metallic coating that reflects infrared heat while allowing visible light to pass through, improving thermal performance.
What is the purpose of glazing tape?
Answer: To provide a compressible seal and cushion between glass and frame
Glazing tape provides a compressible seal and cushion between the glass edge and the frame, creating a weathertight barrier and preventing glass-to-metal contact.
What is spandrel glass used for in curtain wall systems?
Answer: Opaque panels concealing floor slabs and structural components
Spandrel glass is opaque and used in curtain wall systems to conceal floor slabs, columns, and mechanical systems between vision glass areas.
