As homes become increasingly airtight through efficiency measures such as insulation, draught-proofing and double-glazed windows, a lack of ventilation means that activities such as cooking, washing and even breathing builds up moisture in the home. Trapped, this moisture collects on cold surfaces such as windows and outside walls and causes condensation, damp and mould growth, all of which leads to poor indoor air quality.

MVHR systems constantly ventilate a property, meaning that everyday moisture has no time to settle on surfaces as it is extracted to the outside, eliminating the risk of structural and cosmetic damage caused by condensation and mould. They are also extremely efficient, being able to recover up to 91% of heat lost through extraction and transferring it to incoming air.

We understand that every project is different, IEC will specify a system for your requirements and supply install and maintain your system.
