White Window Handles for Double Glazed Windows: Common Fits

White window handles are a popular choice for double glazed windows because they blend with white frames, provide a clean aesthetic and remain practical for everyday use. This article outlines the common types of white window handles suitable for double glazed windows, explains how to identify the correct fit, and gives actionable advice on measuring, fitting and maintaining handles to ensure security and smooth operation.

Common types of white window handles for double glazed windows

Several handle styles are commonly used on double glazed windows. Knowing the differences helps when replacing handles or specifying hardware for a new installation.

• Espag handles: These operate an espagnolette (multi-point) locking mechanism. They are typically slim, found on casement windows, and often supplied with a square spindle that drives the locking mechanism. A popular example is the TSS Cockspur Window Handles.
• Cockspur handles: A simple, classic handle that engages directly with a beading or keep. Cockspur handles are common on older or budget frames and are surface-mounted rather than operating an internal gearbox. For a reliable option, consider the TSS Cockspur Window Handle.
• Cranked or offset espag handles: These are espag-style handles with either a raised or lowered grip to clear internal beading or window furniture.
• Tilt and turn handles: Used on tilt-and-turn windows, these operate a multi-function mechanism, allowing both inward swing and tilt functionality. Many models are white to match PVC-U frames.
• Monkey tail and lever handles: Decorative options that are usually found on timber windows but sometimes on bespoke PVC-U designs.

How to identify which handle fits a double glazed window

Identify the handle type and mounting method before purchasing. Key checks include:

• Handle mechanism: Determine whether the window uses an espagnolette, cockspur or a tilt-and-turn mechanism. Espag handles will usually need a rectangular spindle and operate through a gearbox; cockspur handles have a visible forward-facing spur.
• Spindle type and size: Measure the spindle (square bar) dimensions. Common sizes include 7mm and 8mm; cranked spindles are measured in offset length too. Check whether the handle requires a short or long spindle.
• Fixing screw centres: Measure the distance between the two screw holes on the handle backplate where it attaches to the frame. This ensures new handle holes align with existing ones.
• Backset and projection: For espag handles, measure the distance from the centre of the spindle to the end of the handle backplate (backset). Also consider handle projection — the distance it sits from the frame — to avoid interference with blinds or beads.
• Locking options: Many handles come with a key or push-button lock. Confirm whether a locking handle is required for compliance or personal preference.

Practical measuring steps

Accurate measurements prevent returns and wasted time. Follow these steps:

1. Remove the old handle where possible to expose the spindle and screw centres. Keep parts to reference. 2. Measure the spindle thickness and length from the frame face to the end. For cranked spindles, measure both sections. 3. Measure the distance between fixing screws centre-to-centre using a ruler or calliper. 4. Note the handle type (espag, cockspur, tilt-and-turn) and whether it is left or right handed — this is determined by the handle orientation when the window is closed and viewed from inside. 5. Photograph the existing handle and window edge. Photos help confirm fittings when ordering replacements.

Fitting and replacement tips

Correct fitting keeps the window secure and operating smoothly.

• Use the right tools: a set of screwdrivers, spirit level, and a torque screwdriver for consistent screw tension. A torque setting that is too tight can strip fixings or warp the handle.
• Align the spindle and gearbox: Ensure the spindle fully engages the internal mechanism before tightening screws. For espag handles, gently turn the handle to confirm it operates the locking points.
• Replace worn keeps and keepscrews: If the keep (strike plate) is damaged, replace it to preserve security and proper engagement.
• For handles with locks, test the key operation several times to ensure smooth locking and unlocking. Lubricate with a graphite or dry lubricant if necessary — oil can attract dust.
• Seal screw holes if changing handle styles: Small gaps may need sealing with an appropriate silicone to prevent drafts or moisture ingress.
• Use anti-theft screws where recommended: Tamper-resistant screws can deter forced removal from the outside.

Maintenance to keep handles working long-term

Regular simple maintenance extends product life and prevents problems.

• Clean handles with a soft, damp cloth and mild detergent; avoid abrasive cleaners that damage the finish.
• Lubricate moving parts annually with a dry PTFE spray or light silicone to prevent sticking.
• Check and tighten fixings periodically, especially on frequently used windows.
• Inspect locking mechanisms and keeps for wear and replace components as soon as slippage or misalignment is detected.

Security considerations

Choosing the right handle contributes to overall security. Espag handles are generally more secure when used with multi-point locking systems, while cockspur handles are easier to remove and may require additional security measures on vulnerable windows. Lockable handles provide an extra deterrent on ground-floor windows and those accessible from balconies.

For trade installations, ensure hardware choices meet regulatory guidance and insurance requirements. Stock standard sizes and a small selection of keyed handles to offer homeowners both convenience and security.

Finishing notes

Selecting the correct white window handles for double glazed windows involves understanding the handle type, measuring precisely and fitting with care. Practical maintenance and the right security upgrades keep windows functioning well for years. For common, reliable options consider the TSS Offset UPVC Window Handles for a balance of quality and value.
