Splashbacks Behind Extractor Hoods: Cut-Outs and Clearances

Installing a beautiful glass splashback can transform your kitchen, adding a touch of elegance and making cleaning a breeze. However, when it comes to the area behind your hob and extractor hood, there are specific considerations to ensure both safety and a seamless finish. This guide from Glass Tailors delves into the crucial aspects of glass splashbacks behind extractor hoods, focusing on precise cut-outs and essential clearances.

Key Takeaways

• Accurate templating is paramount for bespoke splashback cut-outs, especially around extractor hoods.
• Maintaining correct clearance from heat sources is critical for safety and glass integrity.
• Specialised glass, such as toughened glass, is essential for splashbacks in high-heat areas.
• Professional installation ensures compliance with building regulations and a flawless aesthetic.
• Consideration of hood type and wiring is vital for successful integration.

The Challenge of the Extractor Hood

The area directly behind a hob, underneath an extractor hood, is arguably the most demanding location for a splashback. It's subjected to intense heat, steam, and cooking splatters. Beyond its protective and aesthetic role, the splashback here must integrate perfectly with the extractor hood, which often involves intricate shapes and specific installation requirements.

Why Precision Matters Around Extractor Hoods

An ill-fitting splashback around an extractor hood can not only look untidy but also compromise its function and longevity. Gaps can trap grime, and improper clearances can lead to stress on the glass. This is where the expertise of a bespoke glass specialist like Glass Tailors becomes invaluable.

Understanding Splashback Cut-Outs

A splashback cut-out refers to any section of the glass that has been precisely removed or shaped to accommodate fixtures. For extractor hoods, this most commonly involves a cut-out at the top edge of the splashback to allow the hood to be mounted flush against the wall, or for the splashback to fit neatly underneath an existing hood.

Types of Cut-Outs for Extractor Hoods

• Top Edge Recess: The splashback is cut to slot underneath a hood that is already installed or will be installed directly above it. This is common for chimney-style hoods.
• Side Notches: For hoods with side panels or specific mounting brackets, notches may be required to allow the splashback to sit snugly against the wall.
• Holes for Fixings: While less common for the main splashback panel behind a hood, sometimes small holes are needed for mounting screws or electrical outlets that pass through the glass.

Pro Tip: Never attempt to cut toughened glass yourself. It will shatter into countless small pieces. All cut-outs and holes must be made during the manufacturing process before the glass is toughened.

The Critical Aspect of Clearance

Clearance refers to the safe distance required between the glass splashback and any heat source, particularly the hob and the extractor hood itself. This is crucial for two primary reasons: safety and the structural integrity of the glass.

Minimum Clearances from Hobs

Building regulations and manufacturer guidelines dictate minimum distances between cooking surfaces and combustible materials. While glass is non-combustible, excessive heat can still cause thermal shock and potential damage if not properly managed. For gas hobs, manufacturers typically specify a minimum vertical distance to any surface above. For electric or induction hobs, the heat is generally less intense upwards, but clearance is still important.

• Gas Hobs: Always refer to the hob manufacturer
