Roof Extensions and Overhangs

Extensions can improve the appearance of a building but will cost more. Roof extensions add "curb-appeal" to some buildings, but will take more time to complete the erection of the building because of the amount of extra covering trim. Extensions can also help a building merge in better in an environment of conventionally constructed buildings in commercial areas. An overhang offers you some protection from the rain and shade from the sun. These options can be important when you receive many visitors to your building, by offering shelter from the elements.

We offer two types of roof extensions: (1) Gable Extensions for endwalls (2) Eave Extensions for sidewalls. Using our system, you can easily and quickly design and price buildings with overhangs up to 5' on any or all of the walls. When in the Building Accessories section select Roof Extensions.

Facings

In addition to acting as a decorative protection barrier, facings serve an integral part of the overall insulation system. Facings provide vapor barriers, light reflectivity and structural strength. In some cases, a reinforcement of fiberglass scrim is used for extra rigidity and greater impact resistance.

The effectiveness of a vapor barrier depends on three primary factors:

1) Location within the insulated section

2) Permeance

3) Proper installation

Thermal Conductance (C-Value)

A measure of the amount of heat that passes through materials of any thickness.

Why are steel buildings so popular?

That's easy. Price. All around price. They are less per square foot than any other known form of construction, and can be erected quickly, offering its owners faster access to their new building. We are seeing more buildings sold for residential use. People are putting up shops and garages faster than you can count. As rural America gets divided into smaller ranches, we see the increase for barns, arenas, horse stalls... etc.

Controlling Condensation

Two things must be present for condensation to occur: warm moist air and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.

In metal buildings, we are concerned with two different areas or locations: visible condensation which occurs on exposed surfaces below dew point temperatures, and concealed condensation which occurs when moisture has passed through the vapor retarder and into interior roof and/or wall cavities and then condenses on a surface below dew point temperature.
