Question 1

What is an Insulated Glass Unit (IGU)?

Accepted Answer

Two or more glass panes with a sealed air or gas space between them

Answer

An IGU consists of two or more glass panes separated by a sealed air or inert gas space that provides thermal and acoustic insulation.

Question 2

Why is argon gas used in double-pane window units?

Accepted Answer

To improve thermal insulation because it conducts heat less than air

Answer

Argon gas fills the space between panes to improve thermal insulation because it conducts heat less efficiently than regular air.

Question 3

What causes a failed seal in an IGU?

Accepted Answer

Moisture infiltration between the panes

Answer

A failed IGU seal allows moisture to infiltrate the sealed air space between the panes, causing persistent fogging or condensation that cannot be cleaned.

Question 4

What is Low-E glass?

Accepted Answer

Glass with a microscopic metallic coating that reflects radiant heat

Answer

Low-E glass has a microscopic metallic coating that reflects infrared heat while allowing visible light to pass through, improving thermal performance.

Question 5

What is the purpose of glazing tape?

Accepted Answer

To provide a compressible seal and cushion between glass and frame

Answer

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.
