What is the nominal clearance that edge blocking should allow between the edge of the glass and the block for an inswing casement window?

• A. 1/4 inch
• B. 1/8 inch
• C. 1/16 inch
• D. 1/2 inch

Answer: (B)

The nominal clearance that edge blocking should allow between the edge of the glass and the block for an inswing casement window is established to prevent potential damage to the glass during expansion and contraction due to temperature changes. A clearance of 1/8 inch is specified as it provides enough space to accommodate these movements while also ensuring stability and proper support for the glass. This clearance helps in minimizing stress on the glass edges, thereby preserving the integrity and longevity of the window installation. It is essential for the edge blocking to have this specific clearance to adhere to industry standards and ensure optimal performance in various environmental conditions.
