Why choose Alustetic to install K·LINE windows?
In 2021, Kline launched a project to create an “expert network,” selecting 20 distributors from across Spain to represent the brand, following the example of the main factory in France.
As soon as the project began, K-LINE gave us the opportunity to be part of it, allowing us to continue training and offering the latest products to our customers.
In 2022, Kline invited us to its headquarters in Nantes for the 1st Kline Expert Convention to learn about all the manufacturing and quality control processes they carry out on a daily basis, to experience them firsthand.
We continue to participate annually in the Expert Conventions to share experiences with other members of the Expert Network and stay up-to-date with the latest developments.

Large-sized sliding balcony door made of aluminium K·LINE
Thanks to its multiple bearings (lower bearings) the leaves slide easily and you only have to push the intuitive handle to open or close the balcony door.
Reduced profiles to obtain maximum light from outside and improve the energy efficiency of your home.
NEW sliding window with MINIMALIST PROFILES from K·LINE windows
Large balcony door with minimalist profiles that are narrower than the KL-BC series to meet the high expectations of the most demanding customers in the reduction of aluminium profiles.
To facilitate the sliding of the leaves, the lower recessed rail has been designed with lower bearings and thus continue with reduced profiles without sacrificing comfort.
Galandage sliding door by K·LINE
The sliding door that hides the leaves inside the wall allows you to open the entire width of the balcony door without losing space towards the interior or exterior of the home. For a better connection between the interior and exterior, you can embed the lower profile of the balcony door and thus have an open space without profiles on the floor.
The door frame is designed to close hermetically and thus achieve good thermal and acoustic insulation.
K·LINE tilt-and-turn window
Panoramic profiles to obtain the maximum glass surface and perimeter security closure that also improves the tightness of the window.
When installing a swing door, you can request the reduced profile to minimise the lower profile without losing the tightness of the window.
K·LINE Premium Entrance Door
K-line Premium model entrance doors are the best choice on the market if you are looking for security and thermal and acoustic insulation.
Wide variety of glazed and paneled models, and multiple side and top compositions depending on the measurements.

Home automation integrated into K·LINE windows and doors
Kline uses Delta Dore technology to control home devices. You can use them for blinds, lights, heating, windows, garage doors and garden fence, alarm, awnings, etc.
You can simulate movement at home wherever you are, create movement routines and control the status of windows and doors at any time (open, in tilt-and-turn position and closed with or without a key if applicable).
K·LINE Smart Home Devices and Kits
DVI: aperture sensor
The DVI (from the French Détecteur de Verrouillage Intégré) or Integrated Lock Detector indicates whether the doors/windows are open or closed, as well as whether the windows that have it are tilted.
These are the three DVI devices available depending on the type of window or door:
Here is what tilt and turn windows look like in the application:
Alarm Pack
This pack is composed of:
- 1 central siren to raise the alarm.
- 1 internal touch keypad that allows you to activate or deactivate the alarm and create multiple surveillance zones.
- 2 mini remote controls to control the alarm.

How is aluminium with Thermal Break differentiated?
Aluminium windows and doors with Thermal Bridge Break (RPT) offer much better insulation than aluminium windows made of cold carpentry (without RPT).
This is because aluminium is a conductive material, and therefore transmits heat, cold and noise through it. But thanks to this break made of PVC (which is an insulating material) we obtain maximum insulation.
The profile of the practicable window is as follows:
KLFP KLINE: section of a swing door with 4-chamber break.
The red part indicates the aluminum, and the gray part in the middle is the PVC.
Another thing that can be seen as different from KLINE is because this PVC has 4 chambers, that is, within a Thermal Bridge Break there are also different categories.
In the blue window you can see this difference.
Other profile: section of a swing door with a broken chamber.
Why choose ALUMINUM instead of PVC?
The main advantage of aluminium over PVC (the entire window, where the PVC remains exposed to the elements) is its durability.
Aluminum is a much harder material that does not suffer the same from environmental factors, whereas PVC is still plastic (a softer material) that can suffer some deformation after a few years.
For this reason, if you are looking for a window that closes well and slides easily today but also in 20 years, we recommend installing aluminium windows.
