What Are Calcium Sulphate Access Flooring Systems?

Calcium Sulphate Access Flooring sealed panels consist of a recycled Calcium Sulphate core sealed with heavy-duty ABS and a galvanized steel bottom. These panels are environmentally friendly, waterproof, rot-proof, fireproof (Class "A" flame spread rating) and provide excellent rigidity, load rating, durability, and acoustic and static performance. The Calcium Sulphate panel is U.S. wood-core compatible without the susceptibility to humidity, temperature, expanding wood core, and de-lamination of the standard wood-core system.

The Benefits of Installing a Calcium Raised Floor System

Flooring plays a critical role in workplace design and functionality. Whether for a new build or a building renovation, consider the benefits a calcium access floor system has to offer:

  • Green materials: These panels are environmentally friendly, "green" building materials that are 100% recyclable and manufactured using sustainable practices.
  • Fire insulation: If you have a fire, these panels are fireproof and will provide insulation that slows the flames and allows extra time for your employees to evacuate.
  • Load capacity: These tiles have an impressive ultimate load rating of 3400 pounds, offer 371.75 pounds of balanced load support per square foot and can withstand 150-pound impacts.
  • Waterproof properties: Calcium raised floor systems are waterproof, making them easy to clean and perfect for safe and reliable installation in high-humidity environments.

Airflow Panels

Calcium Sulphate Access Flooring systems with optional airflow panels are ideal for controlling hot spots and preventing your IT equipment from overheating. These panels are perforated, drawing air traveling through the room down past your equipment and underneath the floor to improve circulation. Depending on how much performance you need, you can choose between standard airflow panels or our high-output model:

Floor Under Structure
