Condensation Explained

Upstanding the basics between Relative Humidity, Specific humidity, Vapour pressure, Thirst, Boundary layers and Dew point.

Before we begin explaining the above where does water vapour come from?

Simple daily life produces water vapour through cooking, washing, ironing, drying clothes and even breathing, therefore it is extremely unlikely that an empty property will suffer with issues of high humidity, condensation and mould… read more



The balance between energy efficiency and ventilation

Most people in Britain are interested in finding new ways to increase the energy efficiency of their homes and spend less money on things like gas and home heating oil.

However, homeowners have been reminded to allow the water vapour that builds up during everyday tasks such as washing clothes and showering to escape, otherwise it can cause condensation and mould.

A study published earlier… read more

loft insulation

CONDENSATION IN ROOF SPACES IS GETTING MUCH WORSE WITH INCREASED LEVELS OF INSULATION.

It is important to remember that the majority of moisture we produce in our homes is created in a gas form as water vapour. Unlike water in a liquid state, water in a gas state can spread easily causing condensation, which may result in damp and decay to vulnerable building materials and… read more



A fan of ventilation

ventilation

Over this past winter i’ve been surveying properties on a daily basis suffering from severe condensation and mould issues, both problems which have become a trend over the last decade with new regulations for insulation and glazing and exaggerated further in new builds by air tightness tests.

As of April 2006 a percentage of new builds now require air pressure testing to comply with building… read more
