customize your fabric covered buildings’ needs
Calhoun’s fabric structures are designed to endure harsh weather, featuring membranes treated with ultraviolet stabilizers to protect against sun damage, ensuring longevity for your fabric cover. The natural lighting provided by these buildings creates a brighter environment than traditional structures, reducing the need for artificial lighting and lowering energy costs. Much of our fabric is the world’s first Membrane Structure Fabric to achieve Cradle to Cradle (C2C) certification through our partner, NovaShield, highlighting its positive impact on people and the planet across five key sustainability categories. With a high strength-to-density ratio, our lightweight materials offer exceptional durability against severe weather while facilitating easier transportation compared to wood or steel. Their thermal conductivity further boosts energy efficiency, and their resistance to UV rays prevents degradation. This unique combination of features results in significant savings in both construction time and maintenance costs.
Endless options to choose from
While Calhoun’s fabric building covers come standard as a white, HDPE, bag, non-fire retardant (depending on size and application), there are several options to choose from to customize your fabric covered buildings’ needs.
With a Calhoun fabric structure cover, you also select from a variety of colors for greater aesthetic appeal and customization.
We recognize that some fabric structures may require fire-retardant (FR) fabric building covers, so we have made this option available. Calhoun’s FR fabric is manufactured with self extinguishing properties to eliminate the flame instead of adding fuel like many other building materials would. It provides extra protection for your assets while abiding by strict building codes.
Depending on your industry, application, and requirements, PVC fabric building covers are recommended due to their durability, versatility, chemical resistance, longevity, and cost-effectiveness. Because of its amorphous structure which contains halogens like chlorine and fluorine, PVC is known for its chemical stability allowing the PVC fabric cover to resist flame, chemicals, and oil.
We offer two fabric building covers installation options depending on the size and budget of your structure: Bag Cover System or Keder Panel System.
Calhoun’s Bag Cover System is a one-piece fabric cover, pulled over the entire structure in one quick and easy step. It is more affordable than other fabric structure cover systems and stays on tighter on smaller structures.
Bag Cover Key Advantage: Affordable and efficient installation. Ideal For: GB Series, smaller CC series
Calhoun’s Keder Panel System does not allow the fabric to touch the structure’s frame, and helps to create a quieter, more secure environment with no risk of wear points on the cover, adding years of life to your structure. Calhoun’s Keder Panel System is standard on all buildings over 60′ wide.
Keder Panel Key Advantage: Quick replacement of individual panels if damaged, instead of removing the entire fabric cover. Ideal For: HT Series, VP Series, larger CC Series
Introducing Elite Fabric Upgrade
Calhoun’s Elite Fabric is a high-performance HDPE cover enhanced with ArmorKote™ Technology for superior durability, UV resistance, and extended lifespan. Its four-layer construction improves abrasion resistance, crack prevention, snow-shedding, and seam strength—making it ideal for demanding environments. Backed by a 25-year warranty (FR or non-FR), Elite adds less than 1% to the total project cost while delivering up to 10 extra years of reliable performance compared to standard covers.
Generational Protection
Elite Fabric takes protection a step further from our standard fabric. Made with rmorKote™ Technology that seals the fabric’s pores, Elite offers greater abrasion and crack resistance than standard materials.
The added UV-enhanced layer dramatically extends the fabric’s lifespan, preserving both strength and appearance; Elite looks newer, longer. In high snow load areas, Elite sheds snow more efficiently when compared to traditional fabric.
Available in both FR and Non-FR.
Built to Withstand a Buffalo, NY Snow Storm
In real-world testing with 6 ft / 1.82 m of snow, Elite fabric demonstrated exceptional performance – snow shed cleanly off the structure, instead of accumulating. For a marginal cost increase averaging less than 1% per project, Elite delivers long-term value. Cleaner, stronger, and longer lasting – the choice is clear.
Check out the comparison of Elite vs. Traditional fabric in the Elite Fabric Infographic.
Calhoun’s 25-year warranty on Elite is a testament to the product’s durability and longevity, backed by years of research and development. With rmorKote™ Technology, this coating improves abrasion resistance, flex resistance, seam strength, and longevity.
