Green Terms Glossary

Passivhaus

Passivhaus refers to a range of proven approaches to deliver net-zero-ready new and existing buildings optimised for a decarbonised grid and augmented for occupant health and wellbeing. Passivhaus buildings provide a high level of occupant comfort using very little energy for heating and cooling. Passivhaus adopts a whole-building approach with clear, measured targets, focused on high-quality construction, certified through an exacting quality assurance process.

When we refer to ISOQUICK being a Certified Passivhaus component, we mean it has been certified by the Passive House Institute. To become certified, the ISOQUICK product underwent independent uniform testing and it has been certified as a high-quality, energy-efficient product suitable for passivhaus construction. The quality seal of certification offers planning reliability to building owners and architects.

Sustainable

Sustainable is used to define those products and processes that cause little or no damage to the environment and therefore are able to support a Net-Zero agenda.

Net-Zero

Net zero refers to a state in which the greenhouse gases going into the atmosphere are balanced by removal out of the atmosphere. Zero energy buildings combine energy efficiency and renewable energy generation to consume only as much energy as can be produced onsite through renewable resources over a specified time period. Due to its sustainability qualities and insulation qualities, ISOQUICK can be part of a net-zero building strategy.

Environmentally Friendly

Refers to those products and processes that are not harmful to the environment. When we use this term in relation to ISOQUICK, we refer to the fact that because it is made from expanded polystyrene it is 98% air, no toxic substances are used in its manufacture, and it is 100% recyclable. Whether in our factory or on-site, any off cuts are broken up and recycled into new products so there is no waste. 

Thermal-bridge free

Refers to installed products in the building envelope that are free of thermal bridges. The total transmission losses under consideration of all thermal bridges must not be greater than the result calculated using the external surfaces and regular U-values of the standard building elements alone. The Passivhaus Institute described ISOQUICK as “The Optimal Thermal Bridge Free Foundation Solution” for its ability to eliminate weak spots. To eliminate thermal bridges builders must also consider their outer wall, roof and window components carefully.

Energy Efficient

Refers to installed products in the building envelope that are energy efficient in that they use only as much energy as is needed without wasting any.
