The cost of a structural glass wall will vary greatly depending on the size and location of the wall. As a general rule, you can expect to pay between £900 and £1,200 per m2 for exterior walls. For single-glazed partitions, you usually have two options for the type of door frame and three options for the type of door. Prices can range from £650 to £1,000 for a frameless glass door (including basic hardware), and from £850 to £1,800 for a frameless glass door with additional features.
In many cases, the hardware is the most expensive component of a standard 10 mm or 12 mm thick tempered glass door. The cost of ownership for frameless single-glazed partitions is minimal. The main ongoing cost will be maintenance, which involves regularly cleaning windows with soap and water and checking the operation of the door and hardware. As long as the product has been installed by trained professionals, the only thing that could go wrong is the operation of the doors and hardware.
The glazed and perimeter frame should last more than 100 years with no major intervention. PVC windows can start from £150 per m2 for a fully glazed unit, with higher quality options available at higher prices. On average, an extension of glass costs £3,000 per m2 just for the glazing. The cost of a frameless single-glazed partition system has two main components: the cost of the actual system and the cost of installation labor.
Variables such as the thickness of the glass (10 mm to 12 mm) and type of frame (aluminum or steel) will affect the cost. Solar control coatings or heated glass will also increase costs. When it comes to installation, time is money so more complex job sites will incur higher costs. You may also need to rent a crane to move large panels of glass around your space, which could add an additional £5,000 to your bill.
The price of structural glass is not easy to determine as it will usually be designed first in terms of wingspan and load before being calculated. Acoustic laminated glass is generally supplied with a thickness of 10.8 mm or 12.8 mm thick. When conducting a cost evaluation exercise, you may find that seemingly comparable windows and doors can vary greatly in price. As such, it is important to consider all factors when deciding on your glass wall.
