High-quality thermal insulation plays a vital role in the energy efficiency of a building. Reducing heating and cooling requirements means reduced greenhouse gas emissions. It can also improve indoor comfort levels, keeping surfaces cool in summer and warm during winter.
Other benefits of having well-insulated buildings include:
improved indoor comfort levels
warmer internal surfaces in winter
cooler internal surfaces in summer
a reduction in the reliance on fossil fuels which contribute to global warming
and improved durability of internal finishes.
Acoustic building insulants are designed to provide additional functions beyond thermal resistance. While thermal insulation may inadvertently reduce noise transmission, acoustic insulation is specifically designed for this purpose. Acoustic insulation is used in residential and commercial spaces. Indoor comfort levels are increased by diminishing penetration of external noise and preventing internal noise from being transmitted to other rooms.
However, the manufacture of insulation products can have negative environmental and social impacts depending on the processes involved. Inappropriate sourcing of raw materials, for example, can lead to the degradation of ecosystems. The use of certain blowing agents can contribute to climate change and ozone depletion. Inefficient use of energy and water during the manufacturing process and sending waste to landfill is environmentally damaging. Some manufacturers may also use hazardous materials and flame retardants linked to adverse health effects.
The standard sets requirements that aim to provide a benefit by:
avoiding the illegal harvest of wood and fibre for raw materials
ensuring that sand and rock is not sourced from within a National Park or threatened ecosystem
setting the amount of recycled content used in the product
banning chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs)
preventing the use of specific hazardous materials and heavy metals such as known carcinogens and mutagens
prohibiting certain flame retardants
ensuring workers and suppliers through the supply chain can expect fair pay, equal opportunity, and a safe working environment
The COVID-19 pandemic has highlighted the very urgent need for us to work together as an international community to address global environmental and social problems. At GECA, we think the stage is set for a new era that celebrates the need for and the benefits of collaboration and transparency while embracing circular economy thinking.Read More See all news
