UPVC (unplasticized polyvinyl chloride) windows have become a popular choice for both residential and commercial buildings due to their durability, low maintenance, and excellent insulation properties. However, a vital yet often overlooked component of uPVC windows is the handle.
The type of handle not only affects the window’s functionality and security but also contributes to the overall aesthetic of the space. This guide explores the various types of UPVC window handles available, their features, and tips for choosing the right one.
Why UPVC Window Handles Matter
Before diving into the types, it's essential to understand why choosing the right window handle is important:
Security: Window handles often incorporate locking mechanisms, contributing to home security.
Ease of Use: Different types of handles provide varying levels of accessibility and ease.
Style: Handles come in various finishes and designs, influencing the appearance of your windows.
Functionality: Some window opening mechanisms require specific handle types for proper operation.
Common Types of uPVC Window Handles
uPVC windows are available with different handle types depending on the window design—casement, tilt-and-turn, or sliding windows. Here are the most common types of uPVC window handles:
1. Espagnolette Handles (Espag Handles)
Overview: These are the most common handle types used in uPVC casement windows. They operate a multi-point locking mechanism through a spindle that turns inside the window.
Features:
Typically have a straight lever.
Locking mechanism operated via a key.
Available in left-handed and right-handed versions.
Most come with standard spindle lengths (usually 40mm or 50mm).
Best For: Outward-opening casement windows.
Pros:
Good security with multi-point locking.
Widely available and easy to replace.
Compatible with most modern uPVC windows.
2. Tilt and Turn Handles
Overview: These handles are used on tilt-and-turn windows, which open in two ways: tilting inward at the top for ventilation, or swinging in like a door for full opening.
Features:
Typically rotate 90 or 180 degrees.
Position of handle dictates window function (locked, tilt, or turn).
Include key-locking for added security.
Best For: Tilt-and-turn uPVC windows in high-rise buildings or modern homes.
Pros:
Multi-functionality in a single design.
Excellent for ventilation and safety.
Modern appearance.
3. Cockspur Handles
Overview: A traditional handle type found mostly in older UPVC windows. Instead of using a spindle, these handles use a spur (nose) that fits over a wedge on the frame.
Features:
Lever-type mechanism.
Requires careful matching of the backset (distance from handle base to nose).
Can come with or without locks.
Best For: Older uPVC or aluminium casement windows.
Pros:
Easy to operate.
Can be fitted as a retrofit option for older frames.
Inexpensive.
Cons:
Less secure than espag or tilt-and-turn handles.
Becoming less common.
4. Inline Handles
Overview: A subtype of espag handles that are straight and symmetrical, allowing them to be fitted to both left and right-hand openings.
Features:
Straight design with no curvature.
Usually includes key-locking.
Spindle operated.
Best For: Casement windows where universal fitting is preferred.
Pros:
Versatile and easy to install.
Ideal for bulk replacements.
5. Cranked Handles
Overview: Another subtype of espag handles, but with a curved lever to fit ergonomically into the hand and provide clearance from obstructions like window trims.
Features:
Available in left-hand and right-hand options.
More ergonomic than inline handles.
Typically lockable.
Best For: Casement windows with restricted space.
Pros:
User-friendly.
Stylish and functional.
6. Spade or Blade Handles
Overview: These handles are typically used in vertical or horizontal sliding windows. They don’t rotate but slide or push to lock/unlock.
Features:
Low-profile design.
Often include a push-button or latch.
Best For: Sliding sash uPVC windows.
Pros:
Minimalist look.
Suitable for tight spaces.
Handle Materials and Finishes
Most uPVC window handles are made from strong, corrosion-resistant materials like:
Aluminum: Lightweight and durable.
Zinc alloy: Provides strength and allows detailed designs.
Plastic (ABS): Cost-effective and corrosion-resistant.
Common Finishes:
White (classic for uPVC windows)
Chrome (modern and shiny)
Satin or brushed nickel (sophisticated look)
Black (sleek and minimal)
Gold or brass (traditional elegance)
Choose a finish that complements your window frame and overall interior design.
How to Choose the Right Handle
When selecting a handle for your uPVC window, consider the following factors:
1. Window Type
Different windows require different handles. For example, tilt-and-turn handles won't work on casement windows, and espag handles can't be used for sliding windows.
2. Security
Look for handles with key locks, especially for ground-floor windows. Some are certified to PAS 24 or other security standards.
3. Handing
Make sure to choose the correct handed version (left or right) for cranked or cockspur handles.
4. Spindle Size and Fixing Centers
For espag handles, check the spindle length and fixing screw hole distance (typically 43mm centers). This ensures a proper fit.
5. Aesthetic Preferences
Match the handle finish and design with your interior decor for a cohesive look.
Maintenance Tips
Maintaining uPVC window handles ensures long-term usability and aesthetics:
Lubrication: Apply a light lubricant to moving parts every 6-12 months.
Cleaning: Use a mild detergent and soft cloth; avoid abrasive cleaners.
Check Screws: Tighten loose screws periodically.
Replace Worn Handles: Don’t ignore signs of wear, especially in lock mechanisms.
Replacing uPVC Window Handles
Most window handles are easy to replace with a few tools:
Remove the Screw Covers: Use a flat tool to pry off.
Unscrew the Old Handle: Typically two screws hold it in place.
Measure Spindle Length: Before buying a new handle, measure the existing spindle.
Fit New Handle: Align and screw into place, then test functionality.
DIY replacements are straightforward, but if your window uses an unusual mechanism, consider consulting a professional.
Final Thoughts
Choosing the right uPVC window handle goes beyond just style—it's a matter of function, security, and comfort. Whether you're outfitting new windows or replacing old handles, understanding the various types ensures that you make the best choice for your needs. From the ubiquitous espag handle to the versatile tilt-and-turn or the nostalgic cockspur, there's a handle for every window type and personal preference.
By knowing what to look for and how each handle functions, you can enhance the look, security, and efficiency of your windows for years to come.
