Which joinery to choose for your home – PVC or aluminium?


The choice of joinery for the home, i.e. windows and doors, is an important decision that affects the comfort, aesthetics and energy efficiency of our home. There are various materials available on the market, but the two most popular are PVC (polyvinyl chloride) and aluminium. Let’s compare these two most popular options.

Window frames made of PVC

Thermal insulation

PVC is a material with high thermal insulation. As a result, PVC windows and doors keep heat inside the building, preventing energy leakage and reducing heating costs. PVC has a low thermal conductivity coefficient, making it an effective thermal barrier. Good thermal insulation helps to maintain a stable indoor temperature without significant heat loss.

Acoustic insulation

In addition to thermal insulation, PVC also has sound dampening properties. PVC windows and doors effectively reduce noise from the outside, providing peace and comfort indoors. The material has a good ability to absorb sound waves, which contributes to the reduction of noise reflecting off the surface of windows and doors.

Durability and resistance

PVC is a durable and weather-resistant material. It does not corrode, fade or require maintenance in the form of painting. PVC windows are resistant to moisture, fungi, pests and other external factors, making them long-lasting and easy to maintain.

Low cost

PVC is often chosen because of its competitive price. The material is readily available on the market and offers good value for money. Both the purchase cost and the installation cost of PVC windows and doors tend to be lower compared to other materials.

Esthetics and availability

PVC is available in a wide range of colours and finishes to suit different styles and aesthetic preferences. It is possible to laminate PVC to create a wood effect without the maintenance required as with wooden windows. PVC can also be easily moulded into different shapes, allowing windows and doors to be tailored to individual design requirements.

Easy maintenance

UPVC is easy to maintain and requires no specialist maintenance. Regular surface cleaning with mild detergents and water is all that is required to maintain its attractive appearance for many years. The material does not need painting or waterproofing, which saves time and maintenance costs.

Window frames made of aluminium

Strength and durability

Aluminium is a high-strength material, making it ideal for the manufacture of windows and doors. Aluminium windows are resistant to deformation and mechanical damage. In addition, aluminium is also resistant to corrosion, making aluminium windows and doors durable and long-lasting. Due to its durability, aluminium is often used in areas with extreme weather conditions.

Slim profiles and larger glazing area

Aluminium has a low strength factor, which means that aluminium profiles can be thinner than other materials such as PVC or wood. This, in turn, allows for a larger area of glazing, which contributes to a greater flow of natural light into the interior. Aluminium windows allow for panoramic views and more open, airy interiors.


Aluminium gives a modern and elegant appearance. Aluminium windows and doors are often chosen for their minimalist design, which blends well with both modern and classic architectural styles. Aluminium is available in a wide range of colours and finishes, giving greater scope for personalisation and matching individual aesthetic preferences.


Aluminium does not require painting or waterproofing, making it easy to maintain. The material resists fading and requires no specialised maintenance. Regular cleaning of the surfaces is sufficient to maintain their aesthetic appearance for many years. Aluminium windows are resistant to moisture, fungi and insects, which translates into their durability and ease of maintenance.

Ecological choice

Aluminium is a fully renewable material, making it a greener choice. Recycling aluminium uses far less energy than producing virgin aluminium. By choosing aluminium windows and doors, you can contribute to sustainability and minimise your impact on the environment.

It is worth noting that the choice between uPVC, aluminium and other materials depends on individual preference, budget and requirements for thermal, acoustic insulation and aesthetics. Each material has its own unique characteristics and advantages, so it is worth consulting a professional to help you choose the best solution for your particular project before making a decision.
