What is the maximum joint width allowed for butt-joint glazing?

The maximum joint width allowed for butt-joint glazing is 1/2 inch. The specification of this width is crucial for maintaining the structural integrity and aesthetic appearance of the glazing system. A joint that is too wide can lead to several issues, including potential water infiltration, reduced thermal performance, and increased susceptibility to structural failure due to thermal expansion or contraction.

In butt-joint glazing applications, the joints need to be designed to accommodate movement while still providing a secure bond between the glass panels. A width of 1/2 inch allows for a sufficient amount of flexibility and expansion without compromising the performance of the glazing system. It is in alignment with industry standards and best practices, ensuring that the glass panels fit closely but can still accommodate slight shifts caused by environmental conditions.
