The average UK citizen spends 16 hours of each day in their home


Recent steps to increase the number of energy efficient homes has increased over the years yet the quality of the air inside is often neglected.

Insulation grants are available but little or no consideration has been given to allow for adequate air exchange to offset the hermetically sealed nature often associated with new buildings. In new buildings ventilation is often a requirement, however they often do not achieve the rates they are designed to.

Achieving a reasonable level of airtightness is important for the energy efficiency of dwellings and the comfort of occupants. Any benefits of improved insulation levels and energy efficient heating systems are lost or reduced if warm air can leak out of a building.
However, whilst most new houses in the UK achieve these levels of airtightness the quality of the air inside is often neglected.

In fact, the Royal College of Physicians reported in February of this year that indoor air pollutants such as cookers, air fresheners, irritant chemicals from new furniture, scented candles, dust mites etc cause thousands of associated illnesses each year.

This house in Midhurst which Timberworks Europe completed 2 years ago has a combined gas and electricity bill of just £75 per month.

Additionally, poor air quality in educational buildings can impair cognitive ability by affecting attention and concentration as well as memory and recognition.

One option is to install mechanical ventilation into buildings. This requires capital outlay and space in the buildings to house the ventilation ducting etc. In addition, there is also ongoing financial and environmental costs associated in running the system.

There is a solution…
Timberworks Europe’s closed panel wall systems will deliver Air Permeability measurements in the range of 2-3 m3/m2/hr and they regulate moisture and air movement.

Our walls have an external void which is open at the ground level and at the soffits and an internal void within the wall itself. The air is changed continuously.

The air in the external void moves faster than air in the inside void. This creates a pressure gradient from inside to out and the stale air and moisture is expelled through the wall and forced out of the building because the external pressure is lower than the internal pressure. The extensive use of ProClima membranes in the walls means that the moisture cannot get back in (works like Gore-Tex).

Expelling moisture and stale air from a building yet retaining the heat is at the heart of proper sustainable, thermally efficient building practice. If this can be achieved without the use of electrically driven mechanical ventilation and heat recovery units then buildings become even more efficient and truly sustainable.

This is exactly how Timberworks buildings work, explains why they are truly sustainable, and why customers are so pleased with their performance

Balscote Village Hall, Oxfordshire - 164 sq.m.

Renewables include solar panels and a Ground Source Heat Pump

At a steady 19 degrees Celsius throughout the year it cost no more than £700 to heat.

Bob Jesson, the Secretary to the Trustees says;

“The heat retention is brilliant. The building is very efficient and everyone who comes comments on its appearance and general comfort. It’s not stuffy”
