Ventilation Technology

Ventilation technology in buildings is a wide area, depending on heating, cooling and exchange of fresh air to ensure good air quality and room climate. The choice of the correct systems for your home or business requires a holistic approach setting targets in energy efficiency (=ongoing costs and environmental impact) and health for individuals represented by oxygen content, humidity. Smart systems do not have to be expensive and can achieve great results. SCS would like to present you with some efficient solutions, which need to be customised for your building.

Why ventilate?

Ventilation of housesIn order to save as much energy and costs as possible, windows, doors as well as walls, ceilings, roofs, etc are build as air tight as possible. Air exchange with the outside should be avoided in order to save heating and cooling costs. At the same time this leads to humidity being trapped within the building, dry air being created by the heating system and oxygen content being reduced by people within the perimeter.

High humidity levels can be created by showering, bathing, cooking, sport, tumble drying. This humid air causes condensations on walls windows, doors, etc, which creates perfect conditions for mould and spores. Especially, when external temperatures are low (in winter) or during the rainy season, condensations are a major problem. Mould and spores can have serious effects on people’s health, structural integrity of buildings, damage finishes and create a shabby and disgusting appearance.

Ventilation ensures that humid air is replaced with dry air immediately reduces the overall humidity and thus reduces condensation. At the same time this dryer air will help evaporate condensated water, which is already attached to ceilings, walls and floors. This evaporated water will then be transported to the outside via ventilation.

Many residential buildings are vacated during the day, so that windows and doors are closed and locked and condensations as well as stale air are trapped.

Many experts and researchers have investigated this problem and developed autonomous (user-independent) ventilation. These systems provide a regular air exchange without compromising of security and energy efficiency. Many systems work on principles of pressure difference; some are controlled by humidity levels. Some centralised systems even regulate the temperature difference of internal and external air via heat exchangers.

Window rebate ventilator (frame ventilator)

Ventilation - Rebate/ Frame VentilatorA rebate or frame ventilator is the smallest and easiest option to provide a basic air exchange. This vent is built into appropriate positions within the window frame replacing the seal with narrow rubber profiles allowing reduced air flow. These are not visible with, when the window is closed and does not impact on design or security, thermal or acoustic properties. A further advantage is that the vent closes automatically under heavy wind or storm.

Glazing rebate ventilator

Ventilation - Glazing Rebate VentilatorGlazing rebate ventilators allow for increased air exchange. In spite of increased air flow, great results for acoustic properties can be achieved; however the vision through the glazing unit can be slightly impaired. These ventilators can be turned or pushed open or close, so that the desired air exchange can be regulated for example during the day or at night differently.

 

Aeromat VT

Ventilation - Aeromate VTThe new Aeromat VT manufactured by Siegenia, Germany is multitalented in ventilation technology. This appliance is mounted underneath or next to the window frame. High air flow as well as capability of heat regain (in winter) can be achieved. Great acoustic properties are guaranteed, so that no negative side effects are caused by installation of this device. Both integrated fans can work silently and very energy efficient pushing air through exchangeable filters. The slide controller allows for continuously-adjustable flow rate. The system is available motorised or operated by pressure difference.
