Frame Materials & Finishes for Windows & Doors

Window frame materials comparison - aluminium, PVC and wood in a modern residence

Choosing the frame material is the most important decision for your new windows, as it determines insulation, durability and the building's aesthetics. Discover the latest technological advances in aluminium, PVC and wood, compare their performance and find the ideal profile system.

In this section we analyse the technical characteristics of each material, protection and coating methods, next-generation hybrid systems and sustainability - so every choice is fully informed.

Aluminium Windows

Aluminium is the most popular choice in Greece, synonymous with robustness and modern design. Here we analyse thermal-break technology, coating options and the technical features that make modern aluminium profiles stand out.

What is a Thermal Break and why is it now essential?

Modern aluminium is no longer "cold". We explain how polyamide strips inside the profile interrupt heat transfer, ensuring top-class insulation without sacrificing structural strength.

Aluminium Coatings: Powder Coat, Anodising or Wood-Look?

The right coating choice determines aesthetics and service life. We compare ultra-durable powders with the anodising process and analyse the advantages of sublimation (wood-look) finishes.

Seaside Windows: Protection from salt air

The coastal environment is relentless on metals. We explain what pre-anodising is and why a Seaside Class certificate is essential for islands and seaside homes.

Cold vs Thermal-Break: Technical Analysis & Heat Loss

An in-depth look at the technical specs. How profile depth and polyamide thickness affect the Uf coefficient, and why "basic" aluminium windows are now banned by Greek energy regulations (KENAK).

Alloys & Wall Thickness: Rigidity for large constructions

Why the aluminium wall thickness plays a decisive role in large openings. How special alloys prevent warping and allow the construction of massive minimal-frame windows.

The Ecological Footprint: Recycling and "Green Aluminium"

Sustainability meets construction. How the industry now produces profiles from 100% recycled aluminium (green aluminium), drastically reducing the carbon footprint in modern (LEED) buildings.

PVC / uPVC Windows

The "smart" choice for top-tier thermal insulation and excellent noise reduction, at a significantly lower initial cost. We bust the myths of the past and analyse how modern uPVC profiles dominate energy upgrades.

uPVC Windows: Pros, Cons & Myths

The ultimate introduction to PVC. We objectively examine its excellent thermal properties, zero maintenance needs and debunk the misconceptions about its long-term durability.

Aluminium or PVC? The Ultimate Head-to-Head Comparison

The biggest dilemma in every renovation. We put both materials under the microscope and compare them directly on cost, thermal loss, security, soundproofing and service life.

PVC Chambers: What do 5, 6 or 7+ chambers mean?

How the air chambers inside a plastic profile act as an insulation shield. Why the number of chambers and profile depth are the keys to the energy class.

Greek Sun & PVC: UV Resistance (Yellowing)

We tackle the number-one consumer fear. How modern "Tropical Class" uPVC windows incorporate special titanium filters that guarantee the white colour will never yellow.

Steel Reinforcement: The "hidden" skeleton of the window

A plastic window on its own can't withstand pressure. We analyse the necessity of the internal galvanised steel that gives PVC the required rigidity and wind resistance.

Health & Ecology: The truth about Lead-Free PVC

Are uPVC windows toxic? The answer is no. We explain the European industry's transition to lead-free formulations using safe calcium-zinc stabilisers.

Wooden Windows

The timeless charm of natural wood meets advanced engineering. Explore how new processing techniques have eliminated past problems, making wooden windows the ultimate premium and eco-friendly choice.

Modern Wooden Windows: Nothing like the past

Forget the draughty windows of the '80s. New manufacturing technology, perimeter seals and precision hardware ensure perfect airtightness and insulation.

Wood Species: Oak, Meranti, Pine or Iroko?

Not all woods are equal. A detailed guide to choosing the right raw material, considering grain, moisture resistance, hardness and budget.

Glulam (Laminated Timber): The secret to stability

Why modern wooden profiles never warp. We analyse the process of bonding wood sheets with alternating grain, which eliminates natural warping stresses.

Wooden Window Maintenance: Myths & Reality

Maintenance is no longer the nightmare it used to be. Modern water-based microporous varnishes protect the wood for years, making a refresh a simple routine.

Solutions for Listed Buildings & Traditional Settlements

Legislation in historic centres and islands is strict. How to choose wooden windows that respect architectural heritage while providing modern insulation.

Ultimate Thermal Insulation: Wood as a natural insulator

By nature, wood has the lowest thermal conductivity coefficient of any frame material. We analyse the top U-values achieved by wooden windows in passive-house construction.

Hybrid & Special Materials

When a single material isn't enough, technology combines the best features of two worlds. From ultra-luxury Wood-Aluminium systems to industrial steel, here lies the cutting edge of modern architecture.

Wood-Aluminium Windows: The Premium Choice

The ideal combination: natural wood warmth on the inside, with an aluminium "cap" on the outside that provides lifetime protection with zero maintenance.

Steel Windows: Industrial Design

The architect's favourite for lofts and industrial spaces. Steel profiles offer unmatched structural strength with exceptionally slim, elegant frames.

PVC-Aluminium Hybrid Systems: The Smart Combination

How to get PVC's top-tier thermal insulation combined with the aesthetic superiority of metal. uPVC windows clad externally with aluminium profiles.

Fiberglass & Composite Materials: The future of windows

What are composite materials and fiberglass? We examine next-gen profiles that offer extreme insulation, warp resistance and unprecedented weight reduction.

Construction Details in Hybrid Systems

When joining wood, plastic and metal, thermal expansion differs. We analyse how elastic connectors allow dissimilar materials to work together harmoniously.

Extreme Security: Ballistic & Blast-Resistant Frames

Specialised applications require special alloys. A look at the ultra-reinforced heavy steel and aluminium frames designed for banks, embassies and high-security residences.
