How do we
measure quality?

Private User

When private users have to choose new windows, they often consider commercial factors only. In other words, they enquire about the price. But the essential information to be considered before choosing is much more, and ignoring some factors fatally causes additional costs.

Choosing the wrong supplier quickly turns into an increase in cost, damage and problems that the end users must then be able to solve on their own. That’s why many customers decide to take one more step, taking into consideration not only the cost, but also the quality/price ratio.

How can we compare two variables that have two different units of measurement? We know the unit of measurement of the price, in our case it is Euro.

But what is the unit of measurement of quality?

The very concept of quality is not so easy to be defined universally, and we at Noval Group, that have always been focused on the customers needs, tried to efficiently assign a value to some qualitative categories.

Below we list the practical advice that we suggest to our customers while they are grappling with the choice of their new windows. A quality window must:

  • Enhance the interior lighting, by letting in as much natural light as possible

  • Improve the thermal and acoustic insulation of the interiors
  • Improve safety against burglary
  • Ensure consistency with the interior design of the house

Our experience suggests that it is recommendable to think about the windows from the early stages of your project, bearing in mind three variables:

  • Climatic conditions of reference Country
  • Performance values in terms of temperature and masonry humidity
  • Evaluation of the architectural style of the building

What does thermal insulation mean?

The value of thermal insulation: 30% energy saving.

The world climate is conditioned by human intervention due to the continuous extraction and use of uncontrolled materials.

The cost of non-renewable energy increases day by day, a factor that determines the cost of electricity. Despite this, there are some measures to be taken to mitigate our environmental impact and reduce costs:

  • Using insulating frames: everyone can contribute to the aforementioned objectives, since the highest energy cost of a house is used in the refrigeration / heating of the interiors.
  • Using aluminum: a 100% recyclable material, which ranks third in terms of supply availability in nature.
  • Choosing systems with thermal break and double glazing: it has been shown that the use of these systems significantly lowers heating / refrigeration costs.

It has been shown that a thermal break window, compared to a simple non-thermic system, increases insulation by 30% which translates into energy savings of about 20%.

What does thermal break insulation mean?

The insulation capacity of a window is not only determined by its ability to reduce the hot-cold passage through its structure, but also by the ability to prevent the diffusion of heat thanks to the materials it is made of.

An aluminum profile is called “thermal break profile” when the internal and external parts are separated by an intersection made of a special material (polyamide) characterized by its extreme insulation capacity and resistance to high temperatures.

This type of profile prevents direct contact between the exterior and interior.

What are the key points for a correct installation?
  • Only galvanized or stainless steel fixing screws should be used.
  • Each subframe must be galvanized.
  • When using thermal break windows, the use of counter frames is not recommended. In this case, it is recommended to use insulation gaskets around the wall perimeter.
  • Any remaining space between the frame and the wall must be filled and adequately insulated.
How to carry out proper maintenance?
  • Aluminum windows do not need much care, just a quick monthly maintenance which consists in cleaning the frame, especially in the corners where the profiles are joined.
  • Cleaning can be done with a soft cloth, soap and water.
  • Do not use any type of solvent.
  • Do not use any pointed object to remove dirt.
