Well said Munter.
Houses relying on sticky tape to keep them air tight are not sustainable as the sticky tape is not accessible when the glue fails!
Forcing mechanical ventilation on home owners is ridiculous. Who wants fans running 24 hours a day, 7 days a week, 52 weeks a year -filters require replacing one or two times a year and the fan motors will burn out probably every two years, not to mention the heat loss despite the so called heat exchange units. All good for job creation but not sustainable.
