New part F ventilation requirement
Why Mechanically Ventilate?
Modern homes are usually built to far higher technical standards than buildings constructed a few decades ago and are much more energy efficient, largely thanks to better heat insulation. One key area of improvement has been to make buildings more airtight so they hold onto the heat we put into them for longer. But there's a drawback: our homes need regular changes of air to keep them healthy. Baths and showers, doing the dishes, clothes washing machines, drying clothes indoors, and even simple breathing produce astonishing amounts of water inside our homes:, a typical family could produce 10–15 litres of moisture each day! Let that problem go unchecked and you'll get problems like mould and mildew, dust mites and a greater risk of asthma. Opening doors and windows is the obvious way to get rid of moisture and bring in fresh air, but if you do that in winter you might just as well flush your money down the toilet: all the heat you've expensively introduced into your home will blow away in the breeze. An old drafty house solves this problem by being automatically well ventilated, but it's probably also freezing cold because it's useless at holding onto heat; a modern energy-efficient home solves the draft problem but may be stuffy and under-ventilated.
Our experience and expertise in the industry means we can install our range of technologically-advanced systems into any property, old or new.
We work with architects, builders, self-builders, renovators, construction companies, building service contractors and the general public.
