BioBased Material 20% Better Insulation

To decrease our energy and water consumption, we should pay more attention to a better insulation of our houses, offices and community buildings.

Of course we know all the classic insulation materials. But using BioBased insulation materials do have a lot of advantages:

  • Bio materials are a lot better for our health
  • BioBased materials have 20% better insulation properties than conventional materials like fiberglass
  • And because BioBased raw material comes from your neighborhood, the insulation material reaches a 50% reduction in embodied energy
  • BioBased materials absorb CO2! So you are contributing to the global CO2 reduction to decrease the CO2 and therefore the global warming

Bio insulation materials

BioBased aggregates such as straw, clay, wheat or grasses mixed with innovative binders might hold the key to a more environmentally friendly construction process and substantial improvements in energy efficiency for everything from individual private residencies to major public buildings.

The European project ISOBIO is one of the large research programs to develop different materials from idea to application, sharing their results with the building industry and key stakeholders group such as construction professionals, local authorities and architects.

Bio insulation for our health

Doctor Alessandro Miani (SIMA Italy) warned already years ago for health issues because of conventional chemical insulation.

One way to improve indoor air quality is using biobased construction materials like hemp and straw. By “breathing”, they offer better ventilation and help reduce damp. 

There are no doubts that BioArchitecture and BioConstructions can contribute to improving the overall health of people. Biobased construction materials have a positive effect on the amount of harmful emissions from the heating systems of our homes, which are the biggest source of thin particulates. It improves the indoor air quality.

And new green roof tiles and a new natural paintings are improving the indoor and air quality.

BioBased Material 20% Better InsulationBreathable, water-resistant walls

Textiles play an important role in the modernization of infrastructure and in sustainable buildings, explains Andrea Bassi, professor at the Department of Civil and Environmental Engineering (Italy).

 

Bassi:

“Nylon and fiberglass are mixed with traditional fibers to control thermal and acoustic insulation in walls, façades and roofs. Technological innovation in materials, which includes nanotechnologies combined with traditional textiles used in clothes, enables buildings and other constructions to be designed using textiles containing steel polyvinyl chloride (PVC) or ethylene tetrafluoroethylene (ETFE). This gives the materials new antibacterial, antifungal and antimycotic properties in addition to being antistatic, sound-absorbing and water-resistant”.

Rooflys is another example. In this case, coated black woven textiles are placed under the roof to protect roof insulation from mould. These building textiles have also been tested for fire resistance, nail sealability, water and vapor impermeability, wind and UV resistance.

Trends in construction are rapidly changing and it is time to take advantage of these alternative methods of insulating your home or business in a way that is safe for our families and the environment.

Circular buildings

Materials can have an impact on the environment in a range of different ways and at different times during their life cycles. For example, the extraction, transportation and manufacturing of raw material consumes energy and produces carbon. However, when the green materials are reused or recycled the wider environmental impact of the material is significantly reduced.

LCA is a method to measure and evaluate the environmental impacts associated with a product, system or activity, by assessing the energy and materials used and released to the environment over the life cycle. CEN is developing a standard, CEN TC350 to ensure methodologies for assessing the sustainability of buildings and construction products are harmonized.
