PVC curb 35/30 fixed

PVC

A curb that’s easily installed over an existing curb. The height of the vertical part below measures 150 mm, which is ideal for insulation. An extra wide lower flange of 150 mm is offered as an option. This lower flange increases the supporting surface and the possibilities to fix the curb. A CE compliant SHE system, Skylux 160° CE, can be provided in the vertical part of the PVC 35/30 curb.

The importance of a curb

A skylight or flat roof window requires a curb for the installation on the roof. A skylight curb ensures rain water drainage and avoids water stagnation. An indispensable element, unless there already is an existing curb mounted on the roof. Some people opt for a wooden curb, but PVC or polyester is actually better. Wood is an other material than the material of a skylight which leads to different expansion with fractures and cracks as a result. But how do you know you're making the best choice?

Easy to install and maintain

PVC curbs are easy to install and compatible with all types of roof membranes. Polyester curbs are very strong yet very light thanks to their composite composition.

Implementation

The PVC curb can be used for fixed or openable plastic skylights, hybrid skylights or flat roof windows. The electric or manual opening system - mounted on the curb - can provide fresh air ventilation. PVC curbs are also used for electric smoke and heat extraction systems. An openable PVC curb (for ventilation) is fitted with hinges and a standard PVC frame. The skylight is installed on this structure.

Price and roof opening can be decisive

A PVC curb costs less than a polyester one. This can be a decisive factor, especially for larger sizes. The size of your roof opening plays a role too: a PVC curb is available in almost any size, a polyester curb is not. If your project concerns an industrial environment, then a metal curb is your best choice. These are very sturdy and non-flammable.

Vertical or splayed curb

In order to choose the right curb, the roof opening (actual opening in the roof) and the desired insulation value are important. Skylux offers two types: vertical and splayed curbs. A vertical curb can easily be installed over an existing curb, enhancing the insulation value. It is therefore often used for refurbishment projects. The splayed curb has a more even light distribution thanks to the splayed light incidence. The skylight mounted on this curb will be less expensive since it will be smaller.
