The Difference Between Inexpensive and High-Quality Mirrors Explained

At first glance, a mirror seems like a simple product: glass with a reflective coating on the back. But when you take a closer look, you’ll find huge differences in the type of glass, the thickness, the edge finish, and the way the frame is mounted. Cheap mirrors often use standard, low-quality float glass with a reflective coating that can discolor or become damaged by moisture over time. This causes the well-known black edge effect, also officially known as mirror rot or oxidation.

High-quality mirrors use HD-grade silver mirror glass. That may sound like marketing jargon, but the difference is clearly noticeable: an HD mirror provides a crystal-clear, true-to-life reflection without distortion. You see yourself exactly as you really look, without colors shifting or straight lines appearing slightly curved. Nordic Style makes mirrors exclusively from this high-quality silver HD mirror glass, which is 4 mm thick as standard and 5 or 6 mm thick for larger models to prevent distortion.

Not all mirror glass is created equal. In cheaper models, the reflective coating is often thinner and less well protected against moisture. That’s exactly why you’re more likely to see dark spots forming along the edges of inexpensive mirrors, especially in areas where moisture is a factor, such as the bathroom or entryway. A high-quality mirror has a protected silver coating that prevents this from happening.

Another key difference: glass thickness. Thinner glass tends to bend slightly, causing your reflection to appear distorted. This is only noticeable when you move or look at the mirror from an angle. This effect is most pronounced in mirrors that are 170 cm or larger. High-quality mirrors compensate for this with heavier glass and a sturdy backing board. That’s why the large mirrors in the Nordic Style collection use thicker glass as a standard feature as the size increases.

With inexpensive mirrors, safety is rarely a priority. If such a mirror breaks, the glass shatters into sharp, dangerous pieces. High-quality mirrors are equipped with explosion-proof safety film on the back. This film holds the glass shards together in the event of a break, which significantly reduces the risk of cuts. This applies to both framed and frameless mirrors in the Nordic Style collection. Both types therefore fall under the category of safety glass.

A frame isn't just decorative. It holds the glass in place, protects the edge, and helps determine how long the mirror will look good. With inexpensive mirrors, you often see frames made of thin plastic or MDF board that has received little or no treatment. These types of materials are sensitive to moisture, which can cause them to swell, peel, or discolor.

High-quality frames are made from materials that truly prioritize durability. Nordic Style uses brushed aluminum for its aluminum models: lightweight, moisture-resistant, and ideal for use in damp areas. For the wooden models, we use FSC-certified pine or solid oak with an ultra-matte varnish finish. This varnish protects the wood without compromising its character: the wood grain remains visible, and the surface retains a matte, refined appearance.

Would you like to see what these wood types look like in real life? Nordic Style offers a sample box containing color samples of all frame colors in aluminum and wood, plus a piece of polished mirror glass. This way, you can assess the quality at home, in your own lighting.

A cheap mirror that you replace after three years is more expensive in the long run than a high-quality mirror that stays beautiful for years. Moreover, product quality also has an environmental aspect: buying a mirror just once means less packaging waste, less transportation, and less material consumption. Nordic Style consciously chooses FSC-certified wood for its wooden models, sourced from responsibly managed forests.

The collection also offers frameless options for those who want as little material as possible: pure mirror glass with a matte-polished edge, without any additions. This is both the most minimalist and the most material-conscious choice.
