ᐅ Sealing of Floor-to-Ceiling Windows on the Exterior Side

Hello everyone.

According to the builder, our floor-to-ceiling windows have been properly sealed from the INSIDE.

The exterior sealing is supposedly our responsibility...

How would you go about doing this?

There will be a fully covered terrace in front of all the windows... but I still think everything should be sealed correctly.

Or am I worrying unnecessarily?

Isn't it just about the step?

Not just the step... You can also quite clearly see the purple insulation.

If I understand correctly, you are getting the house as a complete package from the builder, who is also supplying the windows?

In that case, I would not rely on any "builder-supplied" arrangements for the base waterproofing around floor-to-ceiling windows. If it gets damp, the builder is likely to blame your own work, which could lead to disputes.

Our window installer created a waterproof tray at this point using EPDM tape. However, in your case, you will likely need a smooth render to close off the exposed masonry and provide a suitable surface for the adhesive. Alternatively, liquid waterproofing could be an option.

Our builder informed me by email that the waterproofing from the INSIDE was carried out according to standards.

The forgotten connection...

This is a service owed by the general contractor, as it does not comply with the recognized rules of technology. Apparently, they completely missed the point... Defining this as an owner-side service!
