Since 2000 VELFAC windows and doors have carried the Danish Indoor Climate Label, evidence that our products can make a positive contribution to a good indoor climate as soon as they are installed.

A good indoor climate – and indoor environment – is important for health and wellbeing and depends on a combination of factors including ventilation, daylight and noise levels.

Every day, building users raise the level of internal humidity. This, in turn, increases the risk of mould and a generally poor indoor climate which can have an adverse effect on our health. To counter this, rooms should be aired several times a day using both windows and doors. By encouraging the natural exchange of air within a room, the indoor climate can be improved and the impact of harmful emissions, from electronic equipment for example, can be reduced.

Architectural tools to help optimise atmospheric indoor climate

Provide basic ventilation

  • Develop a ventilation strategy (either natural, mechanical or both), and work with your window supplier to specify the appropriate glazing (usually a combination of fixed, manual, and remote or BMS-controlled window units)

  • Provide additional options for natural ventilation, including extractor fans and air vents

Beware of emissions
