What have been the benefits to you and your home?

It is difficult to say because we did not live in the house before starting the renovation work, but the biggest change we have noticed has come from the improved airtightness, in particular sealing the chimney flues and removing the suspended timber floors. There are no longer significant draughts on a windy day and sealing all the holes in the party wall means that we can no longer smell when our neighbour is baking cakes! We like that the ventilation system can provide fresh air all through the night without having to leave windows open.
