Olympia Steel Buildings Cool Metal Roofing

Olympia Steel Buildings Cool Metal Roofing Is Energy Efficient and Sustainable

A buildings roof can have a tremendous impact on the buildings energy use. Olympia Steel Buildings Zeus Shield cool metal roofing, standing seam metal roof panels are a sustainable, energy efficient roofing product that can reduce energy costs by up to 40% by lowering cooling loads. In fact, cool metal reflective roofs directly save up to 40% in both heating and cooling energy costs as reported by Lawrence Berkeley National Laboratory.

Solar reflectivity (SR) is the ability of a material to reflect solar energy back into the atmosphere. Energy Star requires an SR value of .25 or higher for steep slope roofing and and SR value of .65 or higher for low slope roofs. The Solar Reflectance Index (SRI) used to determine LEED compliance is calculated using values for both reflectivity and emissivity. To meet LEED requirements, roofing material must have an SRI of 29 or higher for a steel slope and 78 or higher for slow slope roofing. 

Olympia Steel Buildings Zeus Shield cool metal standing seam roof for pre-engineered steel buildings and metal building systems is available in a wide variety of finishes, colors, textures and profiles for both steep-slope and low-slope roofing applications. Olympia Steel Buildings Zeus Sheild metal roofs incorporate the new "cool pigment" technology to offer both high total solar reflectance and high infrared emmittance, even with dark colors. The Zeus Sheild standing seam metal roofs cool coatings contain ceramic infrared reflective pigments designed to reflect infrared energy while  absorbing visible light. The result is a Green sustainable building material that can reduce peak energy demand and help mitigate urban heat island effects.

 

Olympia Steel Buildings Roof Sealant For Metal Building Roof Panels

Olympia Steel Buildings Roof Mastic Sealant For Metal Building Roof Panels

Olympia Steel Buildings uses a sealant or mastic tape on its metal building roof panels and on the sides. The side lap panels have have a 1” wide flat mastic strip and the end lap panel has a 1” wide double bead sealant strip that creates a watertight seal. The large 1" seal allows the fasteners to easily hit the mastic and penetrate the sealant, creating a tight seal against water and air infiltration into the steel building, giving you a nice tight building for efficient heating, cooling, ventilation, and protection  against the elements.

Some metal building competitor’s use only a 3/8” or 1/2” wide flat mastic strip on the side lap panel.  This narrow flat mastic strip cannot ensure a watertight seal. Strong winds can force rain against the metal building through the panel overlap, allowing water into the building. Where one vertical panel overlaps another there is only a 3/8” or 1/2” wide flat mastic strip increasing the risk that the screw used to fasten the panels together will missing mastic tape allowing water and air penetration into the building so that you do not have a nice tight energy-efficient building.

Olympia Steel Wind Bracing For Pre-engineered Steel Buildings

Olympia Steel Buildings Wind Bracing

Olympia Steel buildings use sturdy diagonal bracing consisting of heavy steel cables or steel rods. This diagonal bracing forms an “X” configuration in the brace bay, and is attached to the webs of the steel building columns and rafter beams to stabilize the building and provide tremendous strentgh. When diagonal bracing cannot be used as in the case of door openings, heavy metal portal braces are used that are made of welded H-beams. These pre-engineered steel buildings bracing methods transfer all the wind force into the building structure. There is no stress on the steel screws that attach the steel galvalume panels to the girts and purlins and the wind bracing prevents the steel building from swaying in any direction from strong winds.

Competition's Metal Building Wind Bracing

Many metal buildings competitors use diaphragm bracing (panel shear). The metal sheeting on the side is supposed to act as bracing, putting the entire wind load on the metal screws that attach the roof and wall panels to the building structure. The metal wall sheeting does not transfer the wind force to the building structure allowing the building to sway and/or collapse in strong winds.The resulting stress on the metal screws will eventually cause the screw holes in the panels to become enlarged allowing water to leak into the building. Use of the diaphragm bracing building design means that future door openings cannot be placed on the sides of the building. Cutting door openings into the sides of a metal building that is diaphragm braced would cause all the diaphragm action to be lost and the building could collapse. The metal wall sheeting does not transfer the wind force to the building structure, allowing the building to sway and/or collapse in strong winds.

Olympia Steel Buildings Metal Roof Fasteners

Olympia Steel Buildings Metal Building Roof Fasteners

If the metal building fastener is not compatible with the roof, the steel mill will void the warranty. Olympias steel roof fasteners are surgical stainless steel. They are supplied with an assembled neoprene washer to protect against over-tigntening and carry a lifetime warranty against rust. The steel building roof fasteners are 18 parts chrome and 8 parts nickel and will not rust, tarnish, turn gray or black.

 

Competition’ Metal Buildings Roof Fasteners

Some companies use zinc roof fasteners, which will rust and void the roof warranty. Others provide a long-life metal alloy screw that can prevent rust, but will oxidize, turn dark gray or black making the building unattractive.

Olympia Steel Buildings Now Offers An Energy-efficient Color Option

Olympia Steel Buildings has added an energy efficient color choice for its pre-engineered commercial, industrial, agricultural, and residential steel buildings. As more and more people look for ways to do their part to save and protect the environment and reduce their carbon footprint, finding a cost-efficient way to do so is not always easy. From pre-engineered industrial steel buildings to commercial metal buildings, Olympia provides our customers with energy efficient choices without sacrificing the look of the building or the bottom line.
