The basic guidelines for the fitting and handling of glass and glass-ceramics also applies to BOROFLOAT®
When sizing frames and panels, the different thermal expansions of BOROFLOAT® and the various frame materials plus any possible manufacturing tolerances must be taken into account.
If it is necessary for design considerations to use compression fixing of the glass in the frame, this pressure must be applied uniformly all around the edge of the panel (no uneven pressure).
The glass must be fitted in non-distorting frames. If it is not possible to avoid a small amount of torsion, a suitable permanently elastic gasket must be used to prevent the torsion in the frame being transferred to the glass.
There must be no direct contact between glass and metal (or any other hard element of construction). Permanently elastic, heat-resistant materials (e.g. mineral fiber materials) are recommended as an intermediate layer between glass and metal.
