Lintel Benefits

Duplex Double Protection System
Catnic lintels employ not one, but two methods of protection
against corrosion attack: Catnic's unique, sophisticated Duplex double protection system is additional to the Z275 galvanised steel used in manufacture. This distinctive benefit is a core characteristic of Catnic's standard range of lintels, and is manufactured and supplied at no extra cost to customers.

Built-in Damp Proof Course
Many Catnic lintels have a built-in damp proof course (DPC)*, which saves time in construction as no additional DPC is always necessary. To satisfy NHBC and Zurich Municipal technical requirements, Catnic lintels only require a separate DPC in severe exposure areas. Please refer to the Catnic Lintel Technical Guide on our website for more information. Insulated Core Catnic's lintels feature integral insulation to maximise thermal efficiency and minimise cold bridging.
