Em-Vaults are normally specified to fit to a site-formed builder’s curb, although, subject to loading calculations, can be supplied with the Em-Curb PVCu range of upstands. Use the slider below to scroll through the various options available. Click for an enlarged view.

Em-curb upstands

Em-Curbs are designed to be used in conjunction with Em-Vault rooflights to provide a thermally broken interface which in turn helps to improve the overall thermal efficiency of the roof. Em-Curbs represent excellent value for money, enhance the overall appearance of the rooflight and are prefinished white internally, therefore requiring no further decoration.

Splayed Em-Curb upstands give an excellent spread of light through the room whilst the vertical units are available where the dimensions of the roof aperture need to be maintained.

The standard Em-Curb ismade from extruded white PVC-u. The multi-chambered construction gives an exceptionally robust and thermally efficient performance. This curb is suitable for most roof finishes and is available in heights of 150, 300 and 350mm with other heights also available. All ventilation options can be used in conjunction with Em-Curbs.

For wide and multiwall Em-Vault units, we would recommend that a builder’s upstand is formed, rather than a proprietary PVC curb.

Em-Collar adaptors

Em-Collars provide a thermally broken solution for replacing existing rooflights and would typically be installed to an existing builder’s upstand. Consideration should be given to using the PVC 350/s upstand to oversleeve existing site upstand as this reduces site work, especially where existing linings must not be disturbed, e.g.may contain asbestos.
