Aluminium vs Timber Windows in Malta: Which Is Better?
If you're replacing windows in Malta, aluminium, timber and uPVC are all options. This guide focuses on the differences between aluminium and timber.
For many homeowners, the answer depends on three things:
- Comfort
- Planning requirements
- Long-term value
Technical specifications
These are the standard specification options used as the starting point for a Heritage Apertures estimate. The final recommendation depends on the complete opening, property and project requirements.
- Frame profile and glazing basis
- 68 mm wood frame + 32 mm triple glazing is the standard, lower-cost basis. 78 mm wood frame + 42 mm triple glazing is the higher-cost upgrade for stronger soundproofing and insulation.
- Compatibility
- A 68 mm wood frame supports glazing up to 32 mm, including 32 mm double or triple glazing. A 78 mm wood frame supports glazing up to 42 mm; 42 mm triple glazing requires 78 mm.
- Timber options (wood species)
- Oak or Mahogany.
- Glazing and glass finish
- Double or Triple glazing with Clear or Frosted glass.
- Performance options
- Swisspacer thermal edging, plus Acoustic, Security or no performance glass.
- Default estimate basis
- Triple glazing with sun protection and sound/acoustic protection. If no frame profile is chosen, the estimate basis is 68 mm wood frame + 32 mm triple glazing. These are defaults, not customer-confirmed selections.
- Default opening basis
- Inward-opening tilt and turn. Units wider than about 600 mm are usually split left and right; viewed from inside, the right sash is usually the primary opener.
Aluminium Windows
Aluminium windows have been widely installed in Malta for decades.
Advantages
- Lower initial cost
- Minimal maintenance
- Modern appearance
Disadvantages
- Poor insulation in older single-glazed systems
- Higher heat transfer
- More outside noise
- Condensation can be more noticeable
- Usually unsuitable for many UCA and heritage properties
Modern Timber Windows
Today's engineered timber windows are very different from traditional solid timber windows.
Modern systems combine engineered timber frames with high-performance double or triple glazing and premium European hardware, preserving the character of real wood while improving stability.
Advantages
- Excellent thermal insulation
- Significantly reduced outside noise
- Traditional appearance
- Suitable for many UCA properties
- Repairable and refinishable
- Long service life

Comparison
| Feature | Older Aluminium | Modern Timber |
|---|---|---|
| Lower purchase price? | Yes | No |
| High thermal insulation? | No | Yes |
| High noise reduction? | No | Yes |
| Lower condensation risk? | No | Yes |
| Suitable for many UCA properties? | No | Yes |
| Repairable and refinishable? | No | Yes |
| Traditional appearance? | No | Yes |
Is Timber More Expensive?
Usually, yes.
However, homeowners are typically investing in:
What the investment can provide
- Better comfort
- Reduced outside noise
- Improved energy efficiency
- Longer product life
- Better appearance
- Compliance with planning requirements
Rather than simply buying another window.
Which Is Right For You?
If your priority is the lowest purchase price, aluminium may still be suitable.
If your priority is comfort, reduced noise, traditional appearance and long-term value, engineered timber windows are often the better investment.
Every property is different.
