R-Value for Your Commercial or Industrial Roof
If you choose the right roof for your commercial or industrial building, you can save hundreds of dollars on your heating and cooling costs. Opting for an energy-efficient, reflective roof can make or break your monthly energy bill – but how do you know if you’ve made the right decision?
The commercial roofing specialists at Technique Roofing are trained in identifying the most energy-efficient materials, insulation, and roofing system for your building’s needs. One piece of information we use in our work is known as “R-value,” a calculation that refers to a material’s ability to resist thermal movement. Knowing the R-value of available materials can help you make an informed decision for your industrial roof.
What Is R-Value?
The R-value of a material helps a contractor determine how easily heat can travel through a material. The higher an R-value of a roof is, the more insulation it provides. The higher a roof’s insulation R-value, the harder it is for airflow to get in and out of the building. This helps regulate a building’s temperature, keeping you and your employees warm in the winter and cool in the summer.
To calculate the R-value of a material, divide the material’s thickness by its thermal conductivity. The value you receive is the R-value for that material. Each state or local region has different R-value requirements for different building types, so make sure to check with your roofer or local authority to see if the material you want for your roof meets these requirements.
Different places across the United States have different R-value minimum requirements for roofing systems. These values are set by your state, region, or local governing board. If you do not adhere to these building codes when constructing your industrial roof, you will fail building inspections, have to re-install your roof with proper insulation material, and may have to pay fines. Always make sure your contractor knows your local building code – our commercial specialists at Technique Roofing Systems always keep up-to-date with Ohio’s Building Code.
The United States is divided into different climate zones, known as ASHRAE zones. These zones help determine what level of insulation a commercial roof requires. Different climate conditions require specific insulation amounts. Both too much and too little insulation can cause different problems with moisture, temperature, and roof damage. Marine climates, dry climates, and moist climates have differing R-value requirements for this reason.
For example, the state of Ohio falls within two ASHRAE zones: 4 and 5. Both zones are within the moist climate range. According to the Ohio Building Code, both zones have a minimum R-value requirement of R-25 for commercial roofing materials.
Determining the R-value of your roofing materials can help you determine how energy efficient your roof will be. With higher insulation, less air will travel in and out of your building. This keeps your building naturally cooler during the summer and naturally warmer during the winter. As a result, you won’t need to crank the air conditioning or turn up the heat as often – keeping your energy costs much, much lower.
A high R-value material can provide this insulation for your commercial building. You can also combine insulation with a highly reflective roof to increase your energy savings. By reflecting he sun’s UV rays and retaining desirable heat levels, your energy bills can decrease by up to 30%.
Knowing the R-value of your roofing materials is key to constructing an energy-efficient, money-saving industrial roof. Technique Roofing Systems always checks the R-value of our materials, providing you with top-quality, responsible, and up-to-code roofing solutions.
