Which exterior door to choose for a passive house?

A passive house, unlike an energy-efficient house, has even lower energy consumption. Statistically, in the case of energy-efficient houses, energy consumption is reduced by about 30-40%, while in the case of passive houses, energy consumption can be up to 90% lower than that of conventional houses. The main difference lies in the way energy is extracted – passive houses use, among other things, photovoltaics, which power the household with sunlight. No less important is the design of the house itself, the layout of which is designed to reduce heat escape as much as possible and contribute to maximum sunlight in the interiors. This makes passive houses more environmentally friendly, while at the same time allowing significant savings in operating costs.

As in energy-efficient homes, the passive module requires the right choice of doors. Passive doors are no different from energy-efficient doors – their production technology focuses on achieving the lowest possible heat transfer coefficient and insulating materials.

What features do passive doors have?

Passive doors are recognized by their high thermal insulation, revealed in their thickness and the parameters specified by the manufacturer. Passive doors are most often made of wood, steel or aluminum, and their filling is a material with very good insulating properties. At Stalprodukt Zamosc, the doors are filled with polyurethane foam, which shows the best thermal insulation properties in finishing products. In addition, passive doors have special seals that prevent drafts and excessive heat loss.

An important element of passive doors is also the appropriate glass design. As a passive house must take into account the appropriate insolation (both to heat the interior and to reduce the use of artificial light). For this reason, passive doors should be equipped with fanlights or glazing that provides effective thermal insulation.

Choosing a passive exterior door

When choosing a passive door, the first thing to bet on is quality. This one is offered by manufacturers specializing in the manufacture of exterior doors that comply with the current requirements of energy-efficient and passive houses. Experience is a guarantee of customer satisfaction. At Stalprodukt Zamosc we focus on transparency, including in the case of energy-efficient doors. In our catalog you will find a full selection of passive doors. The document includes a list of insulation parameters for individual models of entrance doors. When reading the catalog, it is worth paying attention to the heat transfer coefficient U and the master door tightness class.
