For thousands of years ago, everyone from the ancient Egyptians to the Vikings used mud to keep their homes comfortable. Egyptians built their homes out of mud bricks, while Vikings plastered mud and straw in between the logs that made up their homes to keep the air and extreme temperatures out.

Ancient Greeks and Romans used both cork and a material they called ‘asbestos’, which in classical Greek means “inextinguishable” because of its resistance to heat and fire. In the Middle Ages homes were damp, draft-prone, and col, meaning animal hides and rugs were used to keep the floors warm and hung tapestries on walls to keep drafts and dampness at bay.

Then came a range of insulating materials cellulose, cardboard, straw, sawdust, or cotton. In the mid 1970s, the harmful effects of asbestos were finally brought to light, causing both cellulose insulation and fiberglass batting to be widely adopted in building and construction projects. Both are still used today.

In other words, insulation was first developed to keep cold out, then to mitigate sound, and finally, to prevent fire. While it was noted that mud and animal hide were the first examples of insulative material, today, now have purpose-built, mass manufactured products which assist in an array of sectors, including commercial.

Insulation effectively refers to a material that reduces the transfer of thermal energy. This can refer to thermal, acoustic or fire insulation, with some panels and products able to account for more than one form of insulation. The brilliance and ingenuity of Australian manufacturers has resulted in several superior products able to insulate commercial buildings, irrespective of purpose.

Providing acoustic, thermal, and fire-resistant performance, superior insulation solutions in commercial buildings are non-negotiable. The Australian offerings market wide are consistently at the coalface of industry trends, with each providing architects with adaptable solutions with individual qualities. We’ve curated a portion of our favourites here.

Let's go natural

AIS Group’s Rockwool insulation range is made from natural stone wool, the sustainable and non-combustible material is created through rocks ingeniously spun into fibres.

Available in an array of forms, including rolls, boards and slabs and possessing the ability to be pre-formed, the range is a specification haven for architects. Superior thermal and acoustic performance is backed by the highest level of fire protection (AS1530.1, AS1530.3 and AS4859.1) possible, underlining both its functional and safe qualities.

AIS’ sustainable commitment sees all Rockwool products certified to meet other standards, including the Environmental Product Declaration (EPD) and the Health Product Declaration (HPD).

Made to be environmentally friendly as it is made from recycled materials, Rockwool insulation has also been designed to be more durable than other insulation materials with a longer lifespan. It is resistant to damage from pests and moisture, making it suitable for use in a variety of different climates and weather conditions. It is also a good choice for use in areas with high levels of moisture, as it can absorb, and release moisture as needed.

Sydney’s most exclusive address, Lendlease and Renzo Piano’s One Sydney Harbour, has been insulated with the Rockwool range, with buildings at Melbourne’s Monash University and the University of Technology Sydney also the beneficiary of the AIS range.

Getting high performance

Askin’s XFLAM Insulated Panels are high performance panels that are fully recyclable and can be utilised for roofing, walls, ceilings, and architectural facades, XFLAM’s syntactic thermoset foam core meets all NCC requirements.
