Regardless of whether you are building or renovating, you can lower your power bills when using Reynaers products. Research shows that Reynaer’s sliding doors reduce the heat flow through the building’s windows, which improves the internal comfort of the home and reduces heating and cooling costs each year.
Windows and doors are typical weak points within the thermal enclosure. A leaky building enclosure leads to excess heat transfer, cold spots and potential for condensation. To achieve a continuous airtight enclosure, close attention to detail is required at all joints and penetrations.
The airtightness of a Passive House is measured by means of an air pressure test. Heat Recovery Ventilation systems are critical to ensure clean and fresh air intake and occupant comfort. High performance energy recovery systems (ERV), required for Passive House, helps to reduce energy losses by taking advantage of heat energy from extract air.
A stable building enclosure can dramatically reduce heating, cooling, and ventilation costs, and reduce a building’s carbon footprint. The thermal performance of Reynaers thermally broken windows and sliding doors allows for lower thermal performance, giving the best cost saving for energy loss. Additionally, thermally broken sliding doors and windows are dimensionally stable.
Condensation in buildings has been identified as an issue that requires consistent uniform guidance. The National Construction Code Series (NCC) requirements deal with damp and weatherproofing, ventilation, bushfire safety and energy efficiency.
Driven by fluctuating pressures around buildings, air also leaks inwards and outwards through interior linings by way of holes made for light fittings, light switches, power outlets, pipes and the like. It can also find its way through small gaps under architraves, around windows and doors, and behind ceiling cornices and skirting boards. In addition, outdoor air is deliberately circulated through roof spaces, wall cavities and sub-floor spaces to help them dry. Constantly mobile air carries water vapour with it inside buildings as we release water vapour into the air by breathing and transpiration from the skin, and through daily activities such as cooking, washing, showering, bathing and laundering.
Relative humidity, is the amount of water vapour present compared to the maximum that could be present at the same temperature and pressure. It is always expressed as a percentage. When relative humidity reaches 50% or more, undesirable effects can follow. Persistent high relative humidity can cause:
- dust mite proliferation, particularly in bedding, carpets and soft furnishings, producing inhalation allergens;
- Mould and fungi growth, including wood rotting fungi.
