Hardiplank siding is a brand of lap siding or clapboard. Many homeowners choose to have their home clad in lap siding. There are many benefits as well as things to consider with this type of siding. For example, consumers must wear respirators or dust masks while handling Hardiplank siding to avoid breathing in silica dust.


Like all clapboard siding, Hardiplank siding features a bevelled edge, according to Home Tips, meaning one side is thicker than the other. The bevelled edge on Hardiplank siding acts as a drip edge. Consumers can choose from several textures of Hardiplank siding. According to Vinyl Siding Connect, clapboard siding can be manufactured with relatively smooth textures that mimic vinyl siding and aluminium siding. Hardiplank siding can be painted but Home Tips recommends priming the siding first to keep it from rotting.


According to This Old House, lap siding, including Hardiplank siding, can be fashioned from several types of wood or synthetic materials like fibre-cement. CalFinder.com claims that cedar and redwood are the preferred woods used in clapboard siding because they are durable and more resistant to decay than most other species of wood. Clapboard siding is also resistant to hail and termite damage. This type of siding requires little maintenance and can last for several decades if it is properly maintained.


If you're handy, you can install Hardiplank siding yourself or you can get a contractor to do it. Having a professional contractor install Hardiplank siding will be faster but it can come with a considerable price tag. Each board should overlap the previous board by about 2 inches. The nails used to secure a plank will be covered up by the next plank. This type of siding can be installed over foam insulation.


According to the manufacturers of Hardiplank, 30-year warranties are offered to consumers who have Hardiplank siding installed. James Hardie Building Products Inc. claims that the warranty offered on its siding is the strongest warranty the company makes available to consumers. James Hardie Building Products Inc. will replace or repair defective products under the warranty provided pictures are taken and the manufacturer is notified within 30 days of noticing the defect. Hardiplank siding must be installed properly and meet all state, local and federal building codes or else the warranty is voided. Warranties do not cover damage due to improper shipping, installation or storage. Hardiplank siding that is not being immediately used should be stored flat, kept dry and covered.


James Hardie Building Products offers two types of Hardiplank siding including HZ5 siding and HZ10 siding. According to James Hardie, HZ5 siding is specifically engineered for wet, freezing climates. HZ10 siding, on the other hand, is engineered for hot, humid climates or areas with high precipitation. For the most part, HZ10 siding is only recommended for Southern states such as Alabama, Mississippi, Florida, Texas and the Carolinas.
