How to make the right choice

Replacing or choosing new windows and doors is an investment made for many years to come. However, many people make the same mistakes that later lead to higher costs, inconvenience, and disappointment.

In this article, we have gathered the most common mistakes we see in our practice – and how you can easily avoid them.

Mistake #1: Choosing Based Only on Price

One of the most common mistakes is focusing solely on the lowest price. Cheap windows and doors often mean:

  • Lower insulation performance
  • Low-quality hardware
  • Short service life
  • In the long run, this leads to higher heating bills and the need for replacement.

Solution: Look at the overall quality – profile, glazing unit, hardware, and installation.

Mistake #2: Underestimating the Glazing Unit

Many customers pay attention to the profile but forget that the glazing unit accounts for more than 70% of the window area.

An unsuitable glazing unit can result in:

  • Heat loss
  • Poor sound insulation
  • Condensation

Solution: Choose double or triple glazing according to the orientation and purpose of the room. If necessary, opt for energy-efficient or low-emissivity glass.

Mistake #3: Lack of Professional Consultation

Every project is different – an apartment, house, office, or industrial building has completely different requirements.

We often see customers who:

  • Choose an unsuitable opening type
  • Order incorrect dimensions
  • Do not take orientation and usage requirements into account

Solution: Consulting a manufacturer or specialist from the very beginning saves time, money, and problems.

Mistake #4: Compromising on Installation

Even the highest-quality windows and doors will not perform well if the installation is done incorrectly.

Poor installation leads to:

  • Drafts
  • Moisture and mold
  • Deformation over time

Solution: Trust professional installation using the proper materials and techniques.

Mistake #5: Choosing Incorrectly Between PVC and Aluminium

PVC and aluminium windows and doors are not interchangeable in every situation.

  • PVC is an excellent choice for residential properties
  • Aluminium is more suitable for large openings, façades, and commercial buildings

Solution: The choice should be based on the purpose of the project, not only on appearance.
