PVC windows and balcony doors with ALU cladding
Here you will find answers to the most frequently asked questions about the advantages of PVC windows and doors.

Advantages of combining plastic and aluminium
Plastic and aluminium are high-quality materials that offer benefits when combined. Thanks to their multi-chamber construction, plastic profiles provide excellent thermal insulation values, compensating for the shortcomings of pure aluminium profiles. The outer aluminium cladding makes the window frame weather-resistant and stable. Both materials are very easy to maintain.
Different colours for the outside and inside
Alongside functionality, design undoubtedly plays a key role in choosing windows. Our configurator allows you to choose the window shape individually and also specify colours. By combining two materials, colours for the outside and inside can be selected independently. For example, you can choose an elegant wood appearance inside and anthracite grey outside.
Outstanding insulation
PVC windows and doors provide exceptional insulation, protecting your home from extreme outdoor temperatures and reducing heating and cooling costs. New PVC windows and doors have slimmer frames and larger glass surfaces, allowing more natural light into the home. The glass also has a UV-protective layer to protect furniture and floors from damage caused by UV rays.
Protection from excessive noise
PVC windows provide excellent protection from outside noise, particularly useful for people living beside busy roads or in urban areas. Replacing existing windows with PVC windows solves noise problems, contributing to peace in every room throughout the day and night.
Quality protection for greater security
Thanks to their strong material and laminated glass panes, PVC windows and doors provide additional security. They are harder to force open or create an opening in if the glass breaks. PVC windows and doors also have steel reinforcements, reducing the risk of burglary and forced entry through doors or windows and making your home more secure.
Minimal maintenance
Plastic-aluminium windows are extremely easy to maintain, and modern PVC and aluminium are highly resistant to poor weather and less susceptible to damage. The colour coating also provides additional surface protection for the material. With just a cloth and water, your PVC windows and doors will always look immaculate.
A wide choice of finishes and colours
The days when plastic windows were available only in standard white are long gone. Today, a broad range of colours and finishes is available. You can even achieve the appearance of real wood by choosing a wood-effect finish such as mahogany or golden oak. This option makes your window durable in different weather conditions, UV-resistant and easy to maintain.
Environmental protection
The increased energy efficiency of PVC windows and doors reduces the consumption of natural resources used to heat/cool the home. This reduction affects the processing of those resources, resulting in less negative impact on nature and the environment. At the same time, you save energy, benefiting both your wallet and the environment.
