Passive Building Principles

Passive Building or Passive House is comprised of a set of principles relating to design that determine whether double glazed windows offer high enough levels of energy efficiency and comfort for the building user. One of the metrics used to measure the efficacy of our timber and aluminium windows is that of insulation, with airtightness and imperviousness against outside conditions key to meeting those standards.

Passive House also requires that double and triple glazed windows are able to retain air that has been conditioned by mechanical means. That’s in addition to factors like solar gain, whereby naturally-occurring energy sources are used to create a comfortable indoor climate with a reduced reliance on powered air conditioning. These are just a couple of the many metrics used to determine which windows meet the standard and ours meet every single one.
