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.

Framed Opening Cover Trim

Full cover trim. Provides head and jamb cover trim and sill trim if applicable, so that no red iron is visible at the opening.

Overall Heat Transmission Coefficient (U-Value)

A unit used to express heat passage through a complete building section, including air films. U-Values serve as a basis for determining transmitted heat loss. The lower the U-Value, the higher the insulation value.

Building Permits/Codes

Do I need a building permit to build my metal building? - You will almost always need a building permit. On occasion you will not need a permit to build but you should ALWAYS check with your local building inspector before purchasing a metal building.

When I call my building inspector what should I tell them? - When you get in touch with your building inspector let him know what you're planning and you should be able to receive the information you'll need to get a building permit for your new metal building.

What do I do if I need permit drawings? - We supply the permit drawings to you after you have committed to buy a metal building from us. We will not begin fabrication or shipment until you have completed the approval process. See the Approval Process section of our website.

What about building codes and loads? - Every metal building that we ship is engineered to comply with regional building codes, wind load and snow load requirements (as stated on your plans). When you start designing your metal building, make sure to review your building code specifications very closely. Since there can be varying requirements within regions - you will need to confirm the codes by contacting your local building official. MetalBuildingDepot.Com is not responsible for confirming codes.

Installation and Selection of Insulation

We provide the highest quality products available. However, proper installation and selection is imperative for maximum effectiveness. Please refer to installation instructions to ensure correct procedures are used. Facings that have been torn or punctured are no longer capable of blocking water vapor and may eventually do more harm than good. Be sure to quickly patch any holes in the vapor barrier.

When selecting a facing, special consideration should be given to its reflective quality. A facing with high reflectivity reduces the need for high light levels in work areas. This results in reduced energy costs and increased productivity.

Although the fiberglass insulation itself is not affected by cold weather, the facing is. Colder temperatures can cause cold crack, a situation where the facing becomes brittle and if handled can crack. Bay Insulation recommends that vinyl faced fiberglass products never be installed in temperatures below 40 degrees.
