Glossary of Terms

Argon:

Gas that is used to fill the space between two panes of glass to increase insulation.

Atrium:

Glass cover for a courtyard.

Bay:

The distance from one edge of post to the edge of the next.

Base well:

Also known as a pony wall or knee wall. A short wall that is below the glass.

Cap:

Finish aluminum trim to cover screws or unfinished material differences.

Condensation:

The moisture that deposits on the glass due to temperature changes.

Conduction:

The direction of heat as it flows from one solid material to another throught direct contact.

Conservatory:

A classically designed sunroom.

Convection:

The direction of heat as is flows through gas or liquid.

Double Pane:

Two panes of glass separated by a spacer and sealed making it a sealed unit with air or gas between them.

Eave:

Where the front wall meets the roof.

Flashing:

Metal material that is used to waterproof between layers of construction.

Footing:

Base of a foundation wall, usually concrete.

Foundation:

A wall that something is built on or supported by.

Front Wall:

The full front length of the sunroom between the two gable walls.

Gable End:

The sidewall or end of a sunroom.

Glazing:

A system of glass, gaskets, sealants, framing and any other component used in installation of glass.

Glazing Track:

The base of an extrusion that holds the glass in place.

Gutter:

A track that collects rain or condensation of water and diverts it to the drain.

Heat Transfer:

How heat flows from hot to cold. There are three methods of this, convection, conduction or radiation.

Length:

The dimension that is the same as the front wall.

Low E Glass:

Polaritic coating applied to the surface of glass that reflects long wave energy.

Muntin:

Horizontal member used to support the bottom and top edge of sunroom.

Rafter:

Support member that extends between the ridge and front wall.

Shading Coefficiency:

Measure of how glass transmits solar heat. SILL: Horizontal member that is installed first on the floor or pony wall.

Single Glaze:

One layer of glass.

Solar Control:

The ability of glass to resist heat flow from the sun’s direct radiation, the short wave energy that lies near visible light in the spectrum.

Solar Cool Bronze Glass:

A type of glass that has a heat reflective coating. This type of glass reduces the amount of heat entering your sunroom.

U-Value:

Describes the rate of non solar heat gain or loss through glass.

Weepage System:

A series of holes and channels in the aluminum framing system that allows accumulated moisture to escape outside.
