How to choose between PVC profile and aluminum profile for windows
What to choose for a window in Alicante: PVC or aluminum? A comparison of profiles for a marine climate based on thermal insulation, strength, price, and resistance to sun and salt.
In Alicante, the choice of window profile is a practical solution that directly affects your comfort and utility costs. The local Mediterranean climate has distinct features that need to be considered:
- Lots of sunshine. High levels of UV radiation, which over time tests the material for resistance to fading and deformation.
- Salty air. Proximity to the sea means corrosive activity that affects the lifespan of facade elements.
- Summer heat and humid winters. Effective thermal and sound insulation is required to maintain coolness or warmth, resulting in savings on electricity.
In such conditions, the window material must be reliable - resistant to UV and salt, and most importantly, effectively insulate the premises.
PVC Profile. A Smart Balance of Price and Insulation
Unplasticized polyvinyl chloride is a classic solution that has proven itself well. Why is PVC often chosen in Alicante?
Practical Advantages of PVC Profile
- Good thermal insulation
Thanks to its multi-chamber structure, PVC has low thermal conductivity and effectively retains temperature. This is a direct saving on air conditioning in summer and heating in winter.
- Affordability
If you are undergoing a comprehensive renovation and have a clearly defined budget, PVC is an economically justified solution. You get high insulation ratings without excessive costs.
- Easy maintenance
It does not require painting or special coatings. Regular washing is enough to maintain its appearance.
What to Consider
- UV Impact
Quality profiles are protected by stabilizers. However, constant contact with intense sunlight may over time affect the white profile of low quality.
- Size Limitations
For very large panoramic constructions or doors, PVC may not be stiff enough. To maintain the strength of the frame, they will need to be more massive.
- Design
Despite lamination, a PVC frame will always look more solid than a thin aluminum profile.
Aluminum Profile. Strength for Large Projects and Challenging Conditions
If design, panoramic glazing, and maximum durability are a priority, an aluminum profile will be the best solution.
Advantages of Aluminum Profile
- High strength and durability
Aluminum is resistant to deformation and designed for long-term use (30+ years). It does not crack or change shape under the influence of heat.
- Architectural Possibilities
Due to its high rigidity, aluminum allows for the creation of thin frames with maximum glazing area. This is standard for modern sliding systems and panoramic windows.
- Coastal Resistance
Well-painted or anodized aluminum is inert to salt and moisture. It does not rust and does not require additional protection. This is critically important for properties on the front line.
- Aesthetics
Clean geometry and a wide range of colors (any RAL) perfectly complement modern minimalist design.
Pitfalls to Be Aware Of
- Higher Price
Quality aluminum systems, especially with thermal breaks, are noticeably more expensive than PVC. This is a direct consequence of their strength and durability.
- Need for "Thermal Break"
Aluminum conducts heat well. For a window to be "warm," it must have a "thermal break" - a special insert that separates the external and internal parts of the profile. Cheap "cold" aluminum for residential use poses a risk of condensation and significant heat loss.
Criteria for Decision Making
The choice between PVC and aluminum profiles always comes down to a balance between budget, design, and durability.
Basic Insulation vs. Structural Strength
PVC profiles win in terms of basic thermal insulation - their multi-chamber structure works excellently to maintain temperature without additional complications. At the same time, the aluminum profile excels in rigidity and scale - it allows for much larger glass areas and thinner frames, unattainable for plastic. For aluminum to match PVC in thermal characteristics, it must have a quality thermal break, which increases its final cost.
Price Today vs. Investment for the Future
If your budget is limited, PVC is an economically justified and reliable solution for 15-20 years. The aluminum profile is an investment: it requires higher initial costs, but its operational lifespan and resistance to aggressive marine environments exceed 30 years, which is particularly important for properties on the front line.
Resistance to Coastal and UV Effects
PVC is not afraid of salt, but it has a slight risk of aesthetic degradation due to constant UV exposure. An aluminum profile, protected by powder coating, demonstrates maximum resistance to sun, salt, and moisture - it does not fade or rust.
The final decision is always yours, but keep in mind that the material is only part of the success. The quality of the glazing unit, reliable hardware, and professional installation determine how effectively the window will serve in the given climatic conditions.

What is "cold" aluminum and why can't it be used in housing?
This is an aluminum profile without a thermal break - a special polyamide insert that blocks heat transfer. It is cheap but causes rapid heat loss, condensation, and does not meet the requirements for residential premises in Alicante.
Will a PVC profile withstand salty air on the front line?
The plastic itself is inert to salt. The problem may arise with metal elements (hardware) if they do not have enhanced anti-corrosion coating.
Does aluminum profile really last longer?
Yes. Aluminum, as a metal alloy, is significantly more resistant to mechanical deformation, UV, and changes in geometry over time than PVC. Its lifespan is usually 30 years or more.
So what is better, PVC or aluminum?
There is no "better" option, there is an "optimal" one for you. If you have standard windows and value thermal insulation and budget - PVC is great. If you have panoramic windows with a sea view and need maximum strength - aluminum is indispensable.
Is it worth choosing a PVC profile if the main priority is energy efficiency?
Absolutely. Thanks to its multi-chamber design and low thermal conductivity of the material, a quality PVC profile is one of the best solutions for thermal and sound insulation. This will significantly reduce air conditioning costs in the summer and ensure a comfortable temperature in winter.
