How to choose exterior doors for your home? Guide for investors

The choice of front door is one of the key decisions when building a house. It is not only a visual element – external doors have an impact on the everyday comfort of use, safety and energy efficiency of the building. In this guide, we explain how to choose exterior doors for your home and why aluminium is a solution that you should consider first.

How to choose exterior doors for your home? Key technical parameters

According to the current regulations, the entrance door to a residential building should be at least 90 cm wide and 200 cm high. However, more and more investors are opting for larger sashes – higher and wider, often with side or top glazing.

Here are the parameters that are crucial for exterior doors:

• heat transfer coefficient (Ud) – should not exceed 1.3 W/m²K (according to WT2025); the lower, the better the insulation,
• sound insulation (Rw) – important in the case of houses located on busy streets,
• structural stability – important especially with large leaf dimensions,
• Resistance to weather conditions – rain, snow, sun and temperature changes should not affect the operation of the door.

Exterior doors – what material will they be best made of?

The entrance door to the house can be made of PVC, wood, steel or aluminum. Each material has its own properties, but aluminium doors are increasingly chosen in modern single-family housing – due to their durability, resistance to weather conditions and great design freedom.

It is a solution that allows you to combine aesthetics with functionality and minimal maintenance requirements.

Aluminium doors for the house – why is it worth choosing?

Aluminium doors combine a modern form with durability and functionality. They work well in both traditional and energy-efficient homes. They are also commonly used in residences.

The most important advantages of aluminium doors:

• durability and resistance to deformation – aluminium does not crack, does not absorb moisture and does not change shape under the influence of temperature,
• corrosion resistance – does not require additional protection, even in difficult conditions,
• no need for maintenance – aluminium doors do not require varnishing or impregnation,
• great design freedom – aluminium allows you to create very large sashes

Front doors and security – what should they provide?

The front door should effectively protect the house against attempts to intrude. A properly selected model should enable the use of modern security solutions, such as:

• multi-point locks,
• high-quality cylinders,
• reinforced hinges,
• possibility of integration with the alarm system or Smart Home.

Aluminium doors are often chosen by investors for modern homes – it is worth mentioning at this point the compatibility with smart home systems. Integration with the Smart Home system (fingerprint reader, application control, or automatic locking) is a solution that should be considered already at the design stage.

Modern exterior doors – aesthetics that match modern architecture

Aluminium is a material that fits perfectly into modern house designs. It allows you to create doors with a simple, flush design, with hidden hinges and slender lines.

Effects such as flushing the leaf with the frame or hiding the hinges are also possible in wood and steel, but it is in aluminium systems that they are the easiest to achieve and are most often used.

Which exterior doors for a house? Summary and recommendations

When choosing an entrance door to a house, it is worth taking into account not only the appearance, but also technical parameters, durability, safety and comfort of use.

Aluminium doors meet all these criteria. They combine high aesthetics with durability, resistance to external conditions and wide configuration options. This is a choice that will work in a modern home, regardless of the style of the project.
