So yes it is cheaper to replace a window than a glass wall but it is much much much cheaper and quicker to replace failed panels of a glass wall than sections of failed brick veneer or precast concrete.
Glass wall vs concrete wall cost.
Glass may provide a contemporary aesthetic but the look will cost more money than a wall finished with drywall.
On average however you can expect to pay about 31 ft of concrete wall and 34 per hour of labor for several contractors installing a concrete block wall.
Poured concrete walls cost.
In total the average cost of installing a concrete wall is about 4 459 but that can vary significantly from project to project with reported costs ranging from 2 352 to 6 763 on average.
I am guessing by using glass for walls you refer to glass facades.
Costs to build a wall.
Installing a new wall will run an average of 1 795 with a typical range of 939 and 2 696 due to the complexities of some homes the cost can reach as high as 8 000 installing walls seems easy to do but is ultimately a long messy affair typically involving framing electrical work and drywall.
When direct costs are considered glass facades are much more costlier than brick walls atleast here in india as it requires highly skilled labor and higher material costs.
