Insulating Against Radiant Heat

Traditional forms of mass insulation, like fiberglass, are effective in preventing heat transfer by conduction and convection, but they less effect on radiant heat. Between 80 and 90% of the radiant heat striking fiberglass will pass through or be "emitted". Radiant transfer typically has as much impact on the temperature in a building as conduction and convection. For more information on radiant barrier facings click here.

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.

Ridge Vent

Ridge vents come completely assembled for ease of installation. Ridge vents supplied by Metal Building Depot are of a low profile design to provide gravity type ventilation. Because gravity ridge vents are designed to allow free airflow, some penetration of water during blowing rains is to be expected. Standard available finishes for the ridge vents are polar white and galvalume. Other colors may be available at an additional cost. Nominal ridge vent length is 10'-0". Ridge vents are available with 9" and 12" throats. Bird screens are provided as a standard. The ridge vents can be ordered as continuous or single units. Exterior parts are 26 gage painted or galvalume. Interior parts are all made of G90 galvanized steel. The substructure consists of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms and damper slides are made of 18 gage steel. Manual operation is through activation of a pull bar which is attached internally to bell cranked type lifter arms connected to the damper with Teflon coated pins through the damper slides. Dampers are spring loaded to remain in the open position until the pull bar is operated and locked in the closed position. Dampers operate in a vertical manner. Each vent is opened by a pull chain that extends approximately 12" below the roof unless noted otherwise on the order documents. Other opening mechanisms are available at an additional cost upon special request. Ridge vents should not be placed closer than 5’-0" to the endwall steel line to allow room to properly flash the building. For example, a 90’-0" long building with ridge vents required the entire length should have no more than (8) units. The ridge vents are available with the following accessories:

Thermal Conductivity (K-Value)

A unit used to express the amount of heat, in BTU's per hour, that passes through one square foot of homogeneous material that is exactly one inch thick and has a temperature difference of one degree Fahrenheit between its surfaces. As the K-Value decreases, so does the amount of heat permitted to pass through the material.

RECREATIONAL

Todays sports, conditioning and recreational centers represent a multi-billion dollar business which continues to grow each year. Attractive, ultra-modern facilities are springing up everywhere, offering a myriad of activities to meet the recreational demands of our society.

Immense clear span, low cost-per-square-foot, and low energy costs are vital to the successful construction and operation of recreational facilities. Whether your need is for a tennis, bowling or health club facility, computerized design and manufacturing help our design engineers create building systems that meet the precise demands of recreational facilities with an eye to architectural designs that fit into any surrounding. Our engineers have designed and manufactured buildings for sports courts, sports fields, game rooms, locker rooms, roller rinks, ice rinks, riding arenas, recreational centers and every other pastime you can imagine. The most important element in the design of all these facilities was combining practicality with efficiency, while providing for the customers' needs. Equestrian buildings provide excellent examples of how the flexibility of these custom designs allow for cost-effective solutions to those specific needs. Your dealer can value-engineer a dollar-saving building system that fits the bill, whether your needs include an arena, a barn or a complete riding facility. Available from one stall to one hundred, with a center row or in a shed-row design, our value-engineered horse barns give you maximum space with a functional layout designed to streamline your horse operations. Riding arenas are available fully-enclosed or as a roof-only structure. Clear span arenas are available up to 240 feet wide and in unlimited lengths. Our engineering department and your dealer can work with you to custom design a structure which maximizes your building site with attached barns, tack rooms, or hay storage areas.
