About Roof Heat Insulation Materials (2)

Roof heat insulation materials can be broadly categorized into several types, each working to reduce heat transfer (conduction, convection, and radiation) to maintain a comfortable indoor temperature and improve energy efficiency.

Here are descriptions of two common and effective types:

1. Polyisocyanurate (PIR) Foam Boards

Description: PIR is a rigid foam insulation board with a closed-cell structure produced via a chemical process. The cells trap gas, which is a better insulator than air, resulting in a very low thermal conductivity (lambda value of 0.020 to 0.027 W/mK). They often come with reflective foil facers to create a low-emissivity air gap, which enhances thermal performance by reflecting radiant heat.
Application: PIR boards are a universal solution suitable for all kinds of exposed and ballasted flat roofs, and are often used in pitched roofs to insulate between and over rafters. Their high compressive strength makes them durable for foot traffic during maintenance.
