Glass block windows have poor thermal insulation properties compared to modern energy-efficient windows. They have a lower insulation value (R-value) and can contribute to heat loss in colder climates and heat gain in warmer climates.

In regions with hot and humid weather, glass block windows may trap heat and humidity indoors, leading to discomfort and increased reliance on air conditioning systems. As a result, glass block windows are generally considered unsuitable for warm climates where energy efficiency is a priority.

From the challenges of installation and high cost to poor thermal insulation and limited suitability for warm climates, glass block windows may not be the most practical or cost-effective choice for many homeowners.
