Edges and Chamfers: Where the Premium Hides

When we look at a glass partition or railing, our attention is drawn to the surface of the glass — its color, transparency, reflections. But it is the edge — the treated border — that determines whether the product will look mass-market or premium. And it is not just about aesthetics: the edge directly affects safety.

Types of Edge Work

Ground edge The edge surface is processed with an abrasive, becoming matte and relatively even. The sharp edges are removed, but the surface remains rough. This is the minimum acceptable treatment for tempered glass.

Polished edge After grinding, the edge is additionally polished to a mirror shine. Such an edge is as transparent as the glass surface itself. This is the standard for all visible elements — partitions, shelves, countertops.

Chamfer A chamfer is an angled cut (usually 45 degrees) along the top and bottom edges of the glass. The chamfer width can range from 2 to 30 mm. A chamfer serves two functions: decorative (it creates an expressive line along the edge) and protective (it removes the sharp corner). A double chamfer creates a "frame" effect and makes the glass look visually thinner and more elegant.

Matte edge A less common option — the edge is worked to a uniform matte finish. It suits loft-style or minimalist interiors.

Why It Matters for Safety

An unpolished edge has microscopic irregularities and burrs. Even if they are invisible to the eye, touching the edge can cause a cut. This is especially critical for glass doors, shower partitions and glass shelves. A polished edge eliminates this risk completely.

How to Tell a Quality Edge

Look at the edge at an angle to a light source. A polished edge should be: - Transparent — with no haziness or clouding - Even — with no waves or dips - Free of chips — even microscopic ones - Perpendicular to the surface — with no skew

The chamfer should be symmetrical, with a crisp transition line and no "steps".

The Cost of the Question

A polished edge increases the cost of a product by roughly 10-15% compared to simple grinding. A chamfer adds another 5-10% depending on the width. But in the context of the overall budget for a glass structure, this is a small sum that radically changes the perception of the result.

At Nova Glass, a polished edge is the standard for all products. We do not skimp on details, because it is the details that shape the final impression of the product.
