Feature Lintels |

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.
