A modern home is not only about technology and energy efficiency, but also about style that emphasises its unique character. Choosing an entrance door is a decision that combines security, thermal comfort and timeless elegance. Find out how to match your front door to your home to create a very good first impression.
Energy-efficient entrance doors for the home – warmth and comfort from the threshold
Optimal thermal conditions in your home will allow you to create a space in which you feel comfortable – regardless of the vagaries of the weather. One of the most important parameters to pay attention to when looking for an entrance door for your home is the thermal transmission coefficient, denoted by the Ud symbol.
This determines the amount of heat penetrating the building envelope, i.e. the entrance door, with a temperature difference of 1K (Kelvin). The parameter is expressed in W/m²K. Importantly, the lower the Ud value, the better the thermal insulation of the door, which translates into less heat loss and lower heating bills. Quite simply, the less the better.
You can find an interesting range of energy-efficient external doors at PORTA(https://www.porta.com.pl/drzwi-zewnetrzne-do-domu).
