The T-Vault is normally specified with our PVC Em-Curbs but can be fixed directly to a splayed top builder’s upstand, which can be made of Timber, concrete or metal. Dead and imposed loadings plus lateral thrust calculations can be calculated according to the continuous rooflight technical data.
For more information on Em-Curbs, visit the Em-Curb page.
On the long sides the curb top should be splayed as noted in the table below. Curbs at each end of the rooflight should be horizontal.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Vulcan Roof Glazing Systems is consulted before specifying.
