CPR Façade Upgrades are an award-winning specialist in building façade painting, repair and remediation. Their patented “upseiling” technology means work is completed more quickly, quietly, safely and less intrusively than conventional scaffold-based or abseiling approaches.

The company’s team of engineers, licensed builders, tradesmen and access specialists have successfully upgraded over 300 strata building facades since 2010. Their results have been recognised with 22 NSW Master Painters Association Awards for quality workmanship and excellence in customer service. 

CPR services include façade after-care, with a fully-itemised and documented maintenance plan that follows the manufacturer’s recommendations to ensure your building always looks good and keeps its 10-year warranty.

The technology CPR has invented and patented worldwide enables a building to be painted in around half the time of scaffold or abseiling approaches – with average savings between $20,000 to $200,000.

Network Architectural are the exclusive distributors of the industry’s leading façade products including Mitsubishi ALPOLIC™ NC/A1, a fire-safe, fully compliant aluminium composite cladding composed of a non-combustible mineral core containing zero polyethylene.

Like all ALPOLIC™ products, Mitsubishi ALPOLIC™ NC/A1 has exceptional durability and impact resistance, as well as superior flatness (no oil-canning). The high quality Lumiflon FEVE paint coating makes it highly resistant to weathering, UV radiation, corrosion and colour fading that has been proven in Australian conditions for over 20 years.

Scientifically proven to be the safest aluminum façade product in real life fire tests around the world, Mitsubishi ALPOLIC™ NC/A1 was introduced solely for the Australian construction market, and has the best possible safety rating with the Insurance Council of Australia. It is particularly recommended for high-rise residential buildings where a very high level of fire protection and the use of non-combustible façade materials is required.

Mitsubishi ALPOLIC™ NC is the only aluminium façade product in Australia to come standard with a 20-year FULL replacement warranty backed by the manufacturer that covers material, labour and rectification costs for faulty material. The warranty has no maintenance clauses for cleaning. Mitsubishi ALPOLIC™ NC also receives the tick of approval on sustainability and meets all the NSW Government testing requirements for use in Project Remediate.
