Windcatcher Natural Ventilation Systems & Balanced Flues

Monodraught Windcatcher systems encapsulate any prevailing wind and carry that wind force down into the room below to provide a constant supply of fresh air for natural ventilation. The system is divided internally into four quadrants so that the leeward side of the system acts as a passive stack for removing stale air from the building. Volume control dampers within the system are programmed to control the correct rate of ventilation, according to the building requirements. No matter which way the wind blows, one face of the Windcatcher system that will always act as air intake. The Monodraught Windcatcher systems eliminate the need for air conditioning during summer months and provides all the benefits of free night cooling without compromising the security of the building, since the dampers open fully at midnight to allow the cool night air to purge the building of stale air and they automatically close again at 7am.

SunCatcher Systems

The Monodraught SunCatcher system provides controlled natural ventilation by utilising the Monodraught Windcatcher method and this is combined with the Monodraught SunPipe natural daylight system. As with the Windcatcher arrangement, the prevailing wind pressure carries a continuous fresh air supply, through weather protected louvres, down into the room below, slightly pressurising the internal space. Warm stale air is expelled from the room by the principle of differential temperatures and natural buoyancy of air movement on the opposite side or leeward side of the system.

The heart of this SunCatcher system is the mirror-finish aluminium SunPipe tube which reflects and intensifies natural daylight down into the room below producing the equivalence of up to 1200 Watts of natural light.

SunPipe Systems

Monodraught SunPipes consist of silverised, mirror-finish aluminium tubes that carry sunlight down into the room below. There is virtually no limit to the length of SunPipe or the number of bends that can be used and the SunPipe system terminates in the patented Monodraught SunPipe Diamond dome, which seals the pipe against the ingress of rain, dust or insects. A special ceiling diffuser seals the bottom entry of the SunPipe at ceiling level creating a long column of still air, which acts as an excellent insulator against heat transfer. Accordingly, there is virtually no heat loss in winter months nor solar gain during summer months. Monodraught manufacture a range of 10 different sizes from 230mm to 1500mm diameter and Monodraught’s Design Team provides a full design service. A full installation service is also provided across the UK.

Sola-powered Systems

With the ever-increasing threat of global warming and rising energy prices, Monodraught decided to incorporate solar power into their Natural Ventilation systems wherever possible. This has resulted in four new products; Sola-vent, Sola-boost, Sola-signal, and Sola-extract. Sola-boost only works under sun power during summer months but increases the throughput of ventilation air by 250%. Sola-vent is the solar powered bathroom extract vent, which also incorporates the SunPipe for energy-free operation and Sola-extract is used in conjunction with cross flow ventilation, typically from openable windows, to provide powered extract ventilation – but without any electrical power. Sola-boost systems are available in either circular or square format and are manufactured in a wide range of sizes to suit every application. Sola-signal is still under development but will recognise the Buxton time signal and, therefore, operate the controls totally based on this radio signal.

Special Shapes & Finishes

There is virtually no limit to the style and design of all the Monodraught system range to complement any building design. The most popular shapes are square, round, and rectangular, but oval or hexagonal shapes can be produced. The standard material for Windcatchers is glass fibre but SunPipes are manufactured in polycarbonate with vandal proof ABS flashings.
