7 trending eco-friendly construction materials

With a growing focus on eco-friendly builds, these are the materials experts are using

A new survey from Sell House Fast has revealed the eco-friendly construction materials that building industry experts believe will boom in the coming year.

After speaking to over 580 architects, engineers and construction (AEC) professionals, the research reveals the top seven materials destined to define eco-builds in both the commercial and residential sectors in 2020.

1. Bamboo

69% of architects, engineers and construction professionals agreed that bamboo was the biggest eco-friendly material trend for the next year. While inexpensive and light, bamboo has impressive tensile strength that offers an alternative method to concrete and rebar construction.

2. Straw bales

You may remember the Straw Bale house – a Grand Designs classic, in which the owners uniquely left its straw bale insulation on show to the world. As well as insulating properties, straw bales are naturally fireproof and can be used as a replacement in wall building for concrete, plaster, wood, fiberglass, stone and gypsum.

3. Timbercrete

By mixing sawdust and concrete to create timbercrete, not only are you provided with a much lighter material, but a more eco-friendly product. The sawdust replaces components within concrete that are most energy-intensive to produce.

4. Recycled plastics

While a property such as the Grand Designs Cowshed conversion in Somerset has re-used plastic in a clever way, with roof tiles made of bottle tops roof, modern construction methods using plastic look to re-use waste in the production of concrete. This takes this plastic out of circulation, reducing greenhouse emissions or keeping it from landfill.
