Choosing the right level of privacy without losing the natural light you want in a room.
Obscure glass patterns are typically graded on a numbered scale, often shown as level one through five, where level one offers only very light texture and a relatively clear view through, and level five offers maximum privacy with almost no discernible shapes visible through the glass while still allowing light to pass. Manufacturers usually display these levels as a simple visual chart so you can compare patterns side by side before choosing.
Lower privacy levels, such as level one or two patterns, are often chosen for hallway windows, stairwells or side panels where some visibility is acceptable but a plain clear pane feels too exposed. These patterns tend to have a subtler, more decorative texture and let in slightly more usable daylight because the distortion is less pronounced.
Bathrooms and ensuite windows typically call for higher privacy levels, often level four or five, where the priority is preventing any visible shape or movement from being seen from outside, particularly on ground floor or overlooked elevations. These patterns still transmit good levels of daylight, so the room does not feel dark, but they scatter the light more heavily to obscure detail.
Front door glazing and sidelights commonly use mid to high obscure levels to maintain kerb appeal and allow light into a hallway while preventing a clear view directly into the home from the street. Many composite door ranges pair specific decorative glass designs with a chosen obscure level as part of the overall door style, so it is worth checking the glass specification alongside the door design itself.
Obscure patterns can be combined with low-e coatings, toughened or laminated safety glass, and standard gas fills, so choosing a privacy level does not mean compromising on thermal or safety performance. It is simply an additional specification layered onto the glass build most homeowners already have.
As a general approach, it helps to think room by room rather than applying one privacy level across a whole house: hallways and stairwells can often use lighter patterns, while bathrooms, ensuites and ground floor overlooked windows benefit from higher levels. A supplier's physical sample chart is the most reliable way to judge how a pattern will actually look once fitted.
It refers to how much visibility is obscured through the pane, typically on a scale from one, offering light texture with more visibility, up to five, offering maximum privacy with almost no visible shape through the glass.
Higher levels, often four or five, are typically chosen for bathrooms and ensuites, particularly on ground floor or overlooked windows, since the priority is preventing any visible detail from outside while still allowing daylight in.
Yes, obscure patterns scatter light rather than blocking it, so even higher privacy levels allow good levels of daylight into a room, though the light will appear more diffused than through clear glass.
Yes, obscure patterns can be combined with toughened or laminated safety glass and low-e coatings, so choosing a privacy level does not require compromising on thermal performance or safety compliance.
