Aluminium apertures play a crucial role in our homes, providing insulation, aesthetic appeal, and security. Today’s designers and architects increasingly seek sleek and modern designs, making aluminium the perfect material for such apertures. Let’s explore why aluminium is the ideal choice and how it stands out compared to uPVC, particularly with the Eklip 70 Essential slim profile.

Why Aluminium is the Best Choice
Aluminium is highly versatile and outperforms uPVC in many aspects, especially in the challenging Maltese climate. The sun, wind, and sea salt spray can significantly affect the durability of materials, and aluminium apertures demonstrate superior resistance over time. Modern homes demand minimalistic yet functional designs that ensure energy efficiency while allowing ample natural light. This is where aluminium slim apertures, like the Eklip 70 Essential, excel.
Comparing Aluminium and uPVC: A Closer Look
To understand the advantages of aluminium apertures, let’s compare the Eklip 70 Essential with a typical slim uPVC profile:
Feature | Elip 70 Essential | Slim uPVC |
Side Frame & Flap size | 66.0mm | 93.5mm |
Central Node size | 72.7mm | 95.0mm |
Air Permeability | Class 4 | Class 4 |
Water Tightness | Class E1650 | 9A |
Wind Resistance | C5 | C5 |
As shown in the table, the Eklip 70 Essential is significantly sleeker—42% slimmer than the uPVC profile. Importantly, while uPVC profiles often have a semi-hidden sash (visible from the outside), the Eklip 70 Essential features a completely hidden sash, giving the appearance of a fixed aperture from the exterior. This can be further enhanced by covering the frame from the outside, leaving only the glass visible.

Performance and Efficiency
Both systems exhibit comparable performance, with the Eklip 70 Essential excelling in water tightness. When it comes to thermal transmittance (Uf), the uPVC profile has a Uf value of 1 W/m²K, offering better thermal insulation compared to the aluminium’s Uf of 2 W/m²K. However, the overall performance of the Eklip 70 Essential is highly efficient, especially with its superior water resistance.
Aesthetic and Functional Excellence
The Eklip 70 Essential also features the innovative Arch Invisible handle. Unlike traditional handles, it is almost invisible when the window is closed or tilted, adding to the sleek appearance. This, when complemented with the concealed hinges makes these apertures a must-have.


In terms of finishes, uPVC offers more realistic wood options, while aluminium provides a broader range of anodised and corten (rust effect) finishes. It’s essential to choose finishes suitable for the Maltese climate, particularly for uPVC with film coatings.
Glass Options and Applications
Complementing these apertures with high-quality solar glass with a low g-value enhances their efficiency by minimizing heat transmission from the sun. These sleek profiles are not just for modern homes or apartments; they are also suitable for traditional buildings, replicating the slim iron windows commonly found in such structures.
Environmental Considerations
Modern homes prioritize not only efficiency but also environmental sustainability. Aluminium is a winner in this regard due to its recyclability. Many aluminium profiles are made entirely from recycled materials, making them a more eco-friendly choice compared to uPVC.
Conclusion
For those looking to make a premium statement with their projects, considering all aspects—design, performance, and efficiency—the aluminium Eklip 70 Essential is the ideal choice. Discover the Eklip 70 Essential at Servgroup, located at Kordin Industrial Estate.
