Thermally Broken Lintels: Advancing Fabric‑First Performance and Compliance

Introducing the Next Generation of Thermally Broken Lintels

Catnic’s Thermally Broken Lintel (TBL) range represents the most significant advancement in steel lintel engineering for a generation. Designed to support a fabric‑first approach to building performance, TBL technology reduces thermal bridging, enhances energy efficiency and helps specifiers meet increasingly stringent regulatory requirements.

Our new white paper explores the scientific research behind this breakthrough and provides specialist insight for architects, engineers, housebuilders and installers. Inside, readers will find expert guidance on:

What’s Covered in the White Paper

• Understanding compliance with UK Building Regulations and thermal performance standards
• Applying a fabric‑first approach to reduce heat loss at key junctions
• Durability and long‑term performance of thermally broken steel lintels
• Fire safety considerations for lintel design and specification
• Practical guidance for selecting, detailing and installing TBL products

This resource is designed to support informed decision‑making at every stage of the build process — from early‑stage specification to on‑site installation.
