🧱 Kingspan Building Products Overview

🔹 Building Wraps

Kingspan building wraps are designed to act as a weather-resistant barrier (WRB) that protects structures from air and moisture infiltration. These wraps are installed behind exterior cladding to improve energy efficiency while preventing water intrusion.

Kingspan wraps help:

• Reduce air leaks and drafts
• Improve overall building envelope performance
• Protect against mold and moisture damage
• Increase long-term durability of wall systems

They are commonly used in residential and commercial wall assemblies where controlling airflow and moisture is critical.

🔹 Insulation Boards

Kingspan insulation boards, including XPS and rigid foam panels, provide high thermal resistance (R-value) and long-term performance. These boards are engineered for applications where strength, moisture resistance, and energy efficiency are essential.

Key benefits include:

• High R-value per inch (energy savings)
• Moisture resistance for below-grade use
• Strong compressive strength
• Lightweight and easy installation

Typical applications:

• Foundations and basement walls
• Under concrete slabs
• Exterior continuous insulation
• Roofing systems
