A lightweight, weatherproof, external cladding system that provides moisture management, insulation and the impressive aesthetics of Rockcote’s seamless render giving you an all-in-one walling system.
First impressions count, that’s why the Rockcote Walling System has been designed to deliver a high quality, exterior rendered finish that makes a home truly distinctive.
The Rockcote Walling System has passed extensive independent fire testing procedures and is suitable for bushfire prone areas that require BAL (Bushfire Attack Level) 29 Certification.
The CodeMark Scheme is a building product certification scheme. The rules of the Scheme are available at the ABCB website www.abcb.gov.au. This certification of conformity is to confirm that the relevant requirements of the Building Code of Australia (BCA), as claimed against, have been met.
LRV value on NRG Greenboard Wall Cladding is 40%. This means that NRG Building systems does not recommend the use of colours with an LRV of less than 40% over the NRG Greenboard Cladding System.
Used to describe how light or dark a colour is (it is actually a measure of how much light is reflected by a surface of that colour), LRV works on a black (0%) to white (100%) basis – the higher the LRV, the lighter the colour, meaning less retention of heat and less risk of substrate movement.
Colours with low LRV absorb light energy and convert this to heat. If the heat cannot dissipate then the coating will heat up to very high temperatures. This can break down the coating system and cause blistering over a much shorter time span. It can also lead to thermal expansion in some cases. This can create issues at joints like peaking or cracking, and at corners with the render beads breaking away from the Render.
LRV value can be found on the database of your local render, texture or paint supplier.
