Choosing the right roof deck for your construction project is crucial for ensuring structural integrity, cost-efficiency, and overall project success. At Keystar, we understand the importance of selecting the appropriate materials, and we’re here to help you navigate the options. In this article, we’ll compare Type A roof deck and Type B roof deck to help you determine which is right for your needs.
What is Type A Roof Deck?
Type A roof deck, also known as narrow rib roof deck, is characterized by its 1-1/2” depth and 36” width. This type of decking is commonly used for repairs and patches due to its wide support surface, which is ideal for various types of rigid insulation and roofing materials. Key features of Type A roof deck include:
Wide Support Surface: Provides a broad area for adhesive contact, enhancing the installation of insulation and roofing materials.
Structural Stability: Transfers horizontal and vertical loads effectively into the building frame.
Primer Painted Finish: Typically comes with a primer painted finish for temporary protection during construction.
Custom Lengths Available: Keystar offers stock lengths of 20’-2” and can provide custom lengths to meet specific project requirements.
Applications of Type A Roof Deck
Type A roof decking is often used in:
Repair Projects: Ideal for patching and reroofing due to its compatibility with older construction standards.
Low-Pitched or Flat Roofs: Suitable for buildings with low-pitched or flat roof designs.
Non-Residential Buildings: Commonly used in schools, arenas, malls, supermarkets, and auditoriums.
What is Type B Roof Deck?
Type B roof deck, also known as wide rib deck, is designed for new construction projects where cost-efficiency and structural performance are paramount. Key features of Type B roof deck include:
Efficient Load Distribution: Offers a higher strength-to-weight ratio compared to Type A, allowing for longer spans between supports.
Versatile Design: Can be used in a variety of construction projects due to its enhanced load-bearing capacity.
Cost-Effective: Often more economical for new constructions due to reduced material and labor costs.
Applications of Type B Roof Deck
Type B roof decking is widely used in:
New Construction Projects: Preferred for its efficiency and cost-effectiveness in modern building designs.
Commercial and Industrial Buildings: Ideal for office towers, warehouses, and large-scale commercial developments.
Open Ceiling Designs: Can be left exposed or manufactured with acoustical perforations for sound absorption.
