Professional Frame: Aluminium Windows and Doors

Professional Frame offers a wide range of top-tier aluminium windows. We handle the study, construction, and installation of both casement and sliding energy-efficient aluminium windows. We offer all the top series from Exalco, Alumil, and Europa to help you choose the aluminium windows that suit your specific needs. Don’t hesitate to contact us for any information or questions.

Aluminium windows and doors significantly affect the energy performance of buildings. Therefore, the selection of windows must be meticulous and meet your requirements. Aluminium windows are categorized based on:

• Material of construction
• Thermal break
• Opening method
• Security features
• Durability against time and weather conditions

Energy performance is also crucial in deciding the brand and series of windows to install in your home or business space. Thus, special attention should be given to the coefficients and technical characteristics of aluminium windows.

Aluminium Windows in a Housing Complex in Ymittos

Both complexes were fitted with  Europa ESS34  in grey RAL 7038 color. The sliding windows feature a lift mechanism, and the casement windows come with a perimeter mechanism. Planistar EVO glass with argon was also used in this project.

Aluminium Windows Based on Opening Method

Casement Aluminium Windows Casement aluminum windows can be made with one or more sashes. Their distinguishing feature is the opening method. These windows open like doors, can include tilt functions, and pair perfectly with aluminum insect screens. Some advantages include enhanced insulating properties like thermal insulation and soundproofing, resistance to moisture, and increased security. The superior technical characteristics are mainly due to the perimeter seals and mechanisms we use.

This type is compatible with aluminium shutters and roller shutters and can feature tilting. They are sometimes not chosen due to cost and the need for free space in front of the windows to open. However, their benefits often outweigh their drawbacks. Types include:

• Thermal break
• Standard cold
• Single or double sash
• Rotating

Sliding Aluminium Windows Sliding windows consist of mechanisms with tracks guiding the aluminium sashes. They can be made in larger sizes and require less aluminium surface. They are divided into recessed, where the sashes slide into the wall, and parallel, where one sash slides behind the other.

Recessed sliding windows save space by hiding in the wall. Parallel sliding windows, while similar, have one sash remain closed and slide behind the other. Compared to casement windows, they have slightly lower insulating properties, which can be enhanced if made with a lift mechanism. Sliding windows types include:

• Thermal break (parallel & recessed)
• Standard cold (parallel & recessed)
• Lift and slide

Fixed Aluminium Windows Fixed aluminium windows meet all needs with excellent properties. They are easy to install and offer increased brightness and view in the space. Common uses include shop windows, facades, partitions, and bathroom windows. They are usually combined with sliding and casement windows.

Types include:

• Thermal break
• Standard cold

Energy-efficient & Standard Aluminium Windows Aluminium windows are known for their durability, thanks to aluminium’s resilience as a material. Other advantages include resistance to weather conditions, low maintenance cost, and light weight. The primary categories of aluminium window profiles are standard (cold) and thermal break. The difference in thermal break windows is the polyamide, a material within the profile that enhances sound and thermal insulation properties. Additionally, glass can be double or triple glazed with a special silver oxide film for better energy efficiency.

Differences in performance levels among single, double, and triple glazing are significant. Indicatively:

• Single glazing: 5.7 W/m²K
• Standard double glazing: 2.8 W/m²K
• Energy-efficient double glazing: 1.1 W/m²K
• Triple energy-efficient glazing: 0.6 W/m²K

The lower the thermal transmittance coefficient, the better. Thus, energy-efficient double glazing is approximately three times more insulating than standard double glazing and five times more insulating than single glazing.

Aluminium Windows with Shutters

The boxes for PVC windows and aluminium are the structures that house the shutter and are divided into two main categories: built-on and external.

Each category has its own advantages and disadvantages. Generally, shutters are more functional than casement aluminium shutters. The only aesthetic drawback is the storage box above the window, which can lead to thermal losses due to the holes in these boxes.

Shutter boxes are also divided into thermal break and standard. The primary difference is that thermal break boxes include special insulation on the inner side, such as DOW and polyamides, for better thermal insulation.

External Shutters External aluminium shutters are installed on the outside, right above the frame of the window, preserving the window’s height.

Main Advantages of External Shutters:

• Maintains the useful height of windows.
• Better thermal insulation coefficient because the shutter box is not within the window opening, unlike built-on boxes.

Main Disadvantages:

• Less aesthetic appeal as they protrude from the rest of the wall.
• Reduced security since the guides and the box are outside the wall, accessible to anyone.
• Can only operate with a motor, not manually.
• Difficulty in repairs if there are no balconies.

Built-on Shutters Built-on shutters are boxes placed on the window frame, reducing the clear opening height. The height of the box varies depending on the type of shutters chosen (e.g., aluminium, polyurethane blade, heavy-duty blade, large ventilation, perforated).

Main Advantages:

• Increased security since the guides are screwed behind the window frame.
• Can be operated with electric shutters, manually with a belt, or a combination of both.
• Easier maintenance.
• More aesthetically pleasing than external shutters.

Main Disadvantages:

• Reduces the height of the window.
• Lower thermal insulation if the boxes are not thermal break.
