Product guide

There are many suppliers of MVHR comfort ventilation systems in the UK.  Green Building Store specialises in systems for ultra low energy/ Passivhaus buildings.  We do not aim to supply units for more conventional standards of building, as our particular expertise is at Passivhaus level.  However, at this level, the requirements for these ventilation systems are a little different, as this Guide to Specification outlines.   We believe that it is vital that systems are designed by those who fully understand the requirements for systems at this level of performance.
