Choosing between PVC windows and aluminium windows in Spain depends on what matters most to you—insulation, design, or overall performance.
At Crystal Windows, we manufacture both, helping you find the right solution for your home and the Spanish climate.
PVC Windows – Energy Efficient & Reliable
PVC windows are a popular choice across Europe thanks to their:
- Excellent thermal insulation
- Strong energy efficiency (lower heating and cooling costs)
- Low maintenance and long lifespan
We use premium Deceuninck profiles, designed specifically for the Spanish climate. They won’t fade, yellow, or deteriorate—and come with a 10-year guarantee.
PVC is ideal if your priority is comfort, insulation, and value for money.
Aluminium Windows – Slim, Strong & Modern
Aluminium windows are known for their:
- Slim frames and modern appearance
- Strength for large openings and sliding doors
- Ability to maximise light and views
They’re perfect for contemporary homes, conservatories, and large glass installations.
Standard Aluminium vs Thermal Break Aluminium
When choosing aluminium windows, there are two options:
Standard Aluminium
- Strong and cost-effective
- Best for non-heated areas or where insulation is less critical
Thermal Break Aluminium
- Includes an insulating barrier within the frame
- Significantly improves energy efficiency and comfort
- Helps keep homes warmer in winter and cooler in summer
- Reduces condensation and outside noise
For most homes in Spain, thermal break aluminium is the recommended option for everyday living spaces.
Which Should You Choose?
- Choose PVC windows for maximum insulation and value
- Choose aluminium windows for slim design and larger glass areas
- Choose thermal break aluminium if you want aluminium with enhanced energy efficiency
