The Importance of Rigid Insulation in Flat Roofing Systems

Most flat roofing systems require some kind of rigid insulation under the new roofing system. The biggest reason is that all flat roofing systems require a substrate between the structural decking and the new roof system. The second and more obvious reason is for higher R-values, which building owners are asking for, and building codes throughout New England are requiring.

The Rigid Insulation Installation Process

Rigid Insulation can either be installed over the structural deck or directly over the existing roof system. Rigid insulation is used to provide a substrate between the membrane and structural decking. It is also used to increase the energy efficiency, or “R-value” of your roof system.

For most flat roofing applications, the rigid insulation is fastened down to the structural deck using fasteners. This is known as a mechanically fastened installation and can be used for mechanically attached membrane systems or fully adhered membrane systems.

If the structural deck is not strong enough to fasten into, or if fastening into the deck will be highly disruptive to the building’s operations (concrete decking, for example), the rigid insulation can also adhere to the deck. This uses a 2 part foam adhesive known as an install-stick or only bond, based on the manufacturer you are using. Typically, adhering the insulation to the structural deck is used in conjunction with fully adhered membrane systems.

Types of Rigid Insulation

  1. Polyisocyanurate (Polyiso) Insulation: Known for its high R-value per inch, polyiso is a popular choice for commercial roofing. It is lightweight, moisture-resistant, and offers excellent thermal performance. Polyiso is often used with a facing material, such as foil or fiberglass, to enhance its durability and fire resistance.
  2. Extruded Polystyrene (XPS) Insulation: XPS is a durable, moisture-resistant insulation material that provides consistent thermal performance. It is often used in applications where moisture resistance is crucial, such as below-grade or inverted roofing systems. XPS insulation is known for its high compressive strength and resistance to water absorption.
  3. Expanded Polystyrene (EPS) Insulation: EPS is a cost-effective insulation material that offers good thermal resistance and versatility. It is lightweight and can be used in various roofing applications, including tapered insulation systems for proper drainage. Compared to XPS, EPS is less resistant to moisture but can be treated with water-resistant coatings.
  4. High-Density (HD) Coverboard: HD coverboards, such as those made from gypsum, cement, or HD polyiso, provide a durable and stable substrate for roofing membranes. They enhance the roof system’s impact resistance, fire resistance, and wind uplift performance. HD coverboards are often used in combination with other insulation materials to create a robust roofing assembly.
  5. Fiberboard Insulation: Fiberboard insulation is designed to be an inexpensive way to create a separation between two roof systems. Unfortunately, it does a very poor job resisting moisture and has a habit of soaking up water over time. Typically, it is only used in situations where low cost is the main factor.
  6. Perlite Insulation: Perlite is a lightweight, volcanic glass material that is often used as a coverboard or secondary insulation layer. It can also be installed as the first layer of insulation, directly over the structural decking, to increase the fire rating of the roof assembly. It provides good thermal performance and dimensional stability. Perlite insulation is resistant to moisture, fire, and decay, making it a durable option for commercial roofing systems.
  7. Composite Insulation Boards: These boards combine different types of insulation materials to leverage their individual benefits. For example, a composite board might consist of a layer of polyiso insulation bonded to a layer of HD coverboard. This combination provides high thermal resistance, durability, and impact resistance.

 

Each type of rigid insulation has its specific advantages and is chosen based on the unique requirements of the commercial roofing project, including thermal performance, moisture resistance, fire resistance, and structural support.
