When people picture a glass pool fence or balustrade, they usually picture frameless: an unbroken sheet of glass with almost nothing holding it up. Semi-frameless is the quiet achiever that gets you most of that look for less. Neither is wrong. It comes down to what you value.
The quick version
- Frameless is the seamless, premium look. Thicker glass, discreet spigots or standoffs, nothing between you and the view. Costs more.
- Semi-frameless uses slimline posts between panels. Still open, still clear, fully compliant, and easier on the budget, especially over long runs.
Looks
Frameless wins on pure minimalism. With no posts, the eye reads it as almost invisible, which is why it suits waterfront balustrades and feature pools where the view is the whole point. Semi-frameless has slim vertical posts at intervals. They are tidy and unobtrusive, but they are there, and on a very clean architectural home the difference shows.
Cost
Semi-frameless is the more affordable option. It uses thinner glass, usually 8 to 10mm, and the posts do structural work that frameless asks the glass and fixings to do alone. Over a long boundary the saving adds up. Frameless uses 12mm toughened glass and more precise fixing, so it sits at the higher end.
Glass thickness and fixing
Frameless panels are typically 12mm toughened glass on spigots or standoffs. Semi-frameless panels are usually 8 to 10mm, captured by posts. Both are Grade A safety glass, so both are strong and both shatter safely if they ever fail.
Upkeep
Maintenance is similar for both: an occasional wash to keep the glass clear and a check of the stainless. Frameless has fewer components to keep an eye on, while semi-frameless has posts and fittings to wipe down. On coastal sites, marine-grade stainless matters for both.
So which should you choose?
Choose frameless when the view is the hero and you want the cleanest possible result: a waterfront balustrade, a feature pool, a sharp modern home. Choose semi-frameless when you want the open glass look at a friendlier price, or over a long run where the cost difference is largest. If you are still unsure, we will show you both on site and price them side by side.
Frequently asked
Is semi-frameless glass fencing compliant?
Yes. Semi-frameless barriers meet the same New Zealand safety rules as frameless, using Grade A toughened safety glass. The difference is the look and the price, not the compliance.
What glass thickness does each use?
Frameless is typically 12mm toughened glass on spigots or standoffs. Semi-frameless is usually 8 to 10mm captured between slimline posts.
Which lasts longer?
Both last for decades when installed with the right stainless grade. Frameless has fewer fittings to maintain, but both need marine-grade stainless on coastal sites.
Can I mix both on one property?
Yes, and people often do. Frameless on the feature frontage where the view matters most, semi-frameless along side and back runs to manage the budget.
