What technologies improve the thermal insulation of doors?

Having an exterior door with good thermal performance is not only a matter of convenience and economy, but also a matter of concern for the environment. Nowadays, more and more companies are using various technologies to increase the thermal insulation of their products. In this article, we will present the three most commonly used solutions: gaskets, insulating panels and warm frames.

Seals and the thermal insulation of doors

Gaskets are one of the most important elements affecting the thermal insulation of exterior doors. Their task is to prevent cold air from entering the premises. Good quality gaskets should be flexible, tightly adhere to the door frame and not deform under the influence of temperature.

It is also worthwhile to ensure their regular maintenance to prevent damage and prolong their life. In the case of old and worn seals, it is worth replacing them with new ones, which will insulate rooms more effectively and reduce heating costs.

Door infill – how does it affect the thermal performance of the door?

Door infill is another important element that affects the thermal insulation of exterior doors. Depending on the manufacturer and model, the door infill can be made of different materials, such as polyurethane, polystyrene or mineral wool. The better the quality of the materials, the higher the thermal performance of the door. It is worth paying attention to the heat transfer coefficient (U), which determines how much heat penetrates a unit of surface in a certain time. The lower the U value, the better the thermal insulation of the door. At Stalprodukt Zamosc we invariably use the properties of polyurethane foam as a filler. Our various tests have shown that it works best in the production of energy-efficient doors and cooperates with the other materials used in their construction.

Warm frame – what is it and what benefits does it help achieve?

Warm frame is an innovative solution that is increasingly used in the production of exterior doors. Traditional door frames are made of metals, which are good conductors of heat. As a result, heat from the room escapes through the frames to the outside, resulting in increased heating costs. A warm frame, on the other hand, is a frame made of heat-insulating materials such as wood, polyurethane or plastic. As a result, heat does not escape through the frames, and the thermal insulation of the exterior door is increased. The warm frame for external doors also appears in the new edition of the Stalprodukt Zamosc catalog. Among other things, it is used in the design of Ecotherm doors, which feature the best thermal insulation on the construction market. Thanks to their construction, heating costs are lower, and owners can save on energy bills.
