James Hardie Primeline Newport Weatherboard 4200 x 170mm x 7.5mm PrimeLine is a range of durable fibre cement weatherboards in a range of profiles that imitate traditional and contemporary timber weatherboard styles. Being fibre cement, PrimeLine weatherboards resist damage from rot, moisture, termites and fire when installed and maintained correctly. The time saving HardieLock insert sets the board overlap. Achieves the deep shadow line of a much thicker board. Pre-primed and ready to be painted on-site. The Newport weatherboard profile has a 3mm deep, 29mm wide horizontal groove that's cleverly positioned below the bottom of the overlapping board. This creates an attractive deep 12mm shadow line from the 9mm thick board. One of the more contemporary profiles, it's ideal for modern beach houses, country cottages and Cape Cod style homes.

I've used this product repeatably, is best cut with fibreboard saw blade and gives a seamless fixing free finish which is ready to paint.

Makes for really easy installation but a pain to cut due to the plastic inlay. I found only really a circular saw worked or probably a angle grinder because of the plastic Insert which prevented score and snap method. but once cut extremely quick and easy installation
