Colorcoat Prisma® re-launch your questions answered

26 June 2010 No Comment

Q1: You have re-launched Colorcoat Prisma®, does this mean changes to the guarantee?

Extended and comprehensive testing involving both natural and artificial exposure has given us the ability to extend the Confidex® Guarantee period for Colorcoat® Prisma to up to 30 years.

In certain applications like coastal roofs in the UK, the Confidex® Guarantee period has been extended by as much as 15 years. But there are no changes to the terms and conditions, there is still no requirement to maintain or inspect to validate the guarantee and cut edges are still covered for the life of the guarantee.

As independent verification, Colorcoat Prisma® is BBA certified for durability in excess of 40 years.

Q2: Have you added to the choice of colours available?

Following a series of workshops with architects and colour specialists, Corus has extended the Colorcoat Prisma® range to include 12 solid colours, 12 metallic colours and 3 matt colours. The new colour range reflects current architectural colour trends and ensures the demands of contemporary and architecturally challenging projects can be met.

Q3: My client has asked for a cost effective alternative to traditional roofing materials such as terracotta, or slate tile, or copper. Is this reflected in the new offering?

Colorcoat Prisma® now includes 3 matt colours. By utilising the very latest paint and paint application technology, we have introduced three new matt colours: Terracotta, Anthracite and Copprium. These matt colours have been chosen to replicate more traditional building materials such as terracotta and slate tiles and in the case of Copprium, weathered copper.

The Colorcoat Prisma® matt colours have been designed to achieve individual styles for a variety of applications from churches and domestic roofs to rainscreens and flat panels.

All Colorcoat Prisma® matt colours achieve Ruv4 status proving outstanding colour retention and come with Confidex® Guarantee periods of up to 25 years, the longest guarantee on the market for matt colours.

Q4: Just how durable is the product?

In addition to all colours achieving Ruv4, all solid and metallic colours are certified as RC5. The coil coating standard EN 10169:2009 classifies the corrosive nature of different environments between C1 and C5. Pre-finished steels are then assessed under natural weathering exposure and assigned a corrosion resistance category between RC1 to RC5 (RC5 being the highest corrosion resistance classification).

Samples of Colorcoat Prisma® were exposed for >2 years at the European classified C5 site at Brest on the West coast of France. Analysis of the samples showed had no significant edge peel, blistering or any other signs of coating degradation during this period.

The relevant certification has now been issued by the French Corrosion Institute and confirms that solid and metallic colours of Colorcoat Prisma® are classified as RC5.
