Watch the above video: There are warning from some engineers that condos with window walls will not last – the replacement costs could price owners out of home. Laura Zilke reports.
TORONTO – Floor to ceiling windows offer the million-dollar view that help sell condos across the GTA, but replacing those windows could come with a price tag of $100,000, according to a university professor.
John Straube, a professor of civil engineering and architecture at the University of Waterloo, says the windows on current buildings will have an approximate life span of 30 years.
“Given the current level of technology, thirty years is not unreasonable. If everything is built right and there are no surprises,” said Straube. “The entire wall is made of glass, so it’s going to very costly for materials and cost a lot more money to work on and access.”

The silicone adhesive and rubber gaskets used to install window walls eventually degrade as temperature changes and sun exposure can lead to the aluminium frame to bend causing the windows to fail.
Straube said the window replacement costs can become even more expensive if you’re forced to move temporarily while an exterior window wall is replaced.
