Insulation materials are designed to reduce heat transfer, keeping buildings warm in winter and cool in summer. The effectiveness of insulation is measured by its R-value, which indicates its resistance to heat flow. Higher R-values signify better insulating properties, making it essential for energy-efficient building design.

Technical Features of Insulation Materials

The following table summarizes the key technical features of various insulation materials commonly used in China:

Insulation Type R-Value (per inch) Thermal Conductivity (BTU-in/hr-ft²-°F) Moisture Resistance Fire Resistance Typical Applications
Fiberglass 2.9 – 4.3 0.20 – 0.35 Moderate Non-combustible Walls, attics, floors
Rock Wool (Mineral Wool) 3.0 – 4.0 0.23 – 0.35 High Fire-resistant Walls, roofs, soundproofing
Foam Board 3.0 – 6.5 0.20 – 0.25 Low Varies Foundation, exterior walls
Spray Foam 3.5 – 6.5 0.20 – 0.25 High Varies Walls, roofs, irregular spaces
Bubble Foil 1.0 – 2.0 0.25 – 0.30 Moderate Non-combustible Radiant barriers, duct insulation

Types of Insulation Materials

Different types of insulation materials are available, each with unique properties and applications. The following table compares the most common types:

Type Material Composition Advantages Disadvantages Typical Uses
Fiberglass Glass fibers Cost-effective, good thermal performance Can irritate skin, requires protective gear Walls, attics, ceilings
Rock Wool Natural stone fibers Excellent fire resistance, soundproofing Heavier, more expensive than fiberglass Walls, roofs, industrial applications
Foam Board Rigid foam High R-value, lightweight Vulnerable to moisture, can be expensive Foundation, exterior walls
Spray Foam Polyurethane or soy-based Superior air sealing, high R-value Higher cost, requires professional installation Walls, roofs, irregular spaces
Bubble Foil Aluminum foil with air bubbles Lightweight, reflective properties Lower R-value compared to others Radiant barriers, duct insulation
