Understanding the Three Main Window Types
Windows serve multiple purposes in a home: they allow natural light, provide ventilation, enhance security, and contribute to energy efficiency. The three primary types of windows to consider are:
- Fixed windows: Non-opening panes designed purely for light and views.
- Ventilation windows: Operable designs (casement, sliding, tilt-and-turn, etc.) that allow airflow.
- Combination windows: Hybrid units with both fixed and moveable sections.
Fixed Windows: Pros and Cons
Often used in hard-to-reach places or where ventilation isn’t needed, fixed windows offer:
Advantages:
- Uninterrupted views due to no frame divisions.
- Better thermal insulation (no moving parts mean fewer air leaks).
- Lower maintenance (no hinges or handles).
Limitations:
- No ventilation option.
- Cleaning exterior surfaces may require ladder access.
Ventilation Windows: Pros and Cons
Ideal for rooms needing airflow, ventilation windows include:
- Casement (side-hinged, excellent for catching breezes)
- Sliding (space-saving, common in apartments)
- Tilt-and-turn (secure, multi-functional opening)
Advantages:
- Adjustable airflow and natural cooling.
- Emergency escape routes (if sized appropriately).
Limitations:
- Potential dust ingress in high-pollution areas.
- More components (seals, hinges) that may wear over time.
Combination Windows: Pros and Cons
These blend fixed panels with operable sections, offering:
Advantages:
- Design versatility (e.g., large picture window with side vents).
- Optimised light and airflow in the same unit.
Limitations:
- Higher upfront cost due to complexity.
- Frame divisions may slightly obstruct views.
Factors to Consider When Choosing Windows
Energy Efficiency
Look for:
- Multi-chambered uPVC profiles (reduce heat transfer)
- Double glazing (argon-filled for better insulation)
- Weather stripping on operable windows (minimises drafts)
Security Features
- Reinforced frames and multi-point locking systems.
- Tempered glass for ground-floor windows.
Aesthetic Appeal
Consider:
- Frame colours (white vs wood-grain finishes)
- Grid/mullion patterns for traditional or modern looks
Budget Considerations
- Fixed windows are typically most affordable.
- Combination windows involve higher fabrication costs.
Which Window Type is Best for Different Rooms?
Living Rooms and Bedrooms
Prioritise light and views here. Fixed or combination windows work well, with ventilation units placed strategically for cross-breezes.
Kitchens and Bathrooms
Mandatory ventilation makes tilt-and-turn or sliding windows practical. Smaller openings help manage humidity.
Conservatories and Extensions
Large fixed glass panels maximise sunlight; add vents along the top or sides for heat regulation.
FAQs About Choosing Windows
Can fixed windows be cleaned from inside?
Yes—if reachable with standard tools. For upper floors, ensure tilt-in functionality or external access.
Are casement windows secure?
Modern designs include shootbolt locks and anti-jemmy features, making them as secure as other types.
How long do uPVC windows last?
Quality uPVC windows typically last 25–35 years with minimal maintenance (cleaning and seal checks).
