The Best Materials for Coastal Construction
Living by the coast offers breathtaking views and a serene environment, but it also poses unique challenges for construction due to the corrosive effects of salty sea air. Coastal homes and structures require materials that can withstand the harsh conditions and ensure long-lasting durability. Here are some of the best building materials for coastal locations.
Fibre Cement Cladding
Fibre cement is a composite material made from cement, sand, and cellulose fibres. It’s a popular choice for coastal homes as it’s not only resistant to salt air but also to insects and fire. Demand for fibre cement cladding continues to grow in Australia as it’s low-maintenance, provides design flexibility and takes up less floor space than brick cladding.
James Hardie uses fibre cement to make products look like other materials such as timber weatherboards, vertical joint timber, rendered walls and metal panels. These products are durable because they’re resistant to fire (and deemed non-combustible), rot, and damage from moisture and termites.
Brick Veneer
Brick veneer closely resembles natural brick, is lightweight, easy to install, and offers high insulation capacity. Its durability, fireproof nature, and no-paint appeal make it a practical and low-maintenance option, particularly suitable for coastal homes.
Natural Stone Cladding
There are a number of natural stone cladding systems available in Australia, featuring materials like granite, limestone, and quartzite. A standout quality of stone lies in its exceptional insulation and thermal performance, enhancing a home's energy efficiency and minimising its carbon footprint. With non-porous and non-absorbent properties, stone provides effective moisture protection and robust resistance against harsh weather conditions.
Internally, stone exudes undeniable presence and character, making it an excellent choice for feature walls. Externally, it contributes to an appealing, rustic aesthetic, requiring minimal upkeep as a house cladding option.
Metal Cladding
Considered a sturdy and reliable cladding option, metal cladding comes in various types, with steel and aluminium being the most popular. Steel, being more durable, often comes at a higher cost. Aluminium composite panels (ACP) provide a more cost-effective alternative, albeit with a slightly higher susceptibility to weather-related damage.
Both steel and aluminium cladding are available in diverse profiles, including corrugated or trapezoidal, and are favoured for the contemporary ambiance they bring to homes.
Marine-Grade Lumber or Composite Products
When it comes to wooden construction in coastal areas, marine-grade lumber is the go-to choice. This type of wood is treated with preservatives and sealants that enhance its resistance to decay, insects, and water damage. Commonly used marine-grade woods include teak, cedar, and redwood, all of which provide an appealing aesthetic while ensuring longevity in the salty sea air.
Alternatively, timber-looking composite products are heat and water-resistant, making them a great choice for coastal homes.
Building in coastal locations requires careful consideration of the materials used to withstand the challenges posed by salty sea air. By prioritising durability and corrosion resistance, homeowners and builders can create homes that not only embrace the beauty of coastal living but also stand strong against the elements for years to come.
