It can be installed onto warm roof applications with up to 140mm thick insulation (if unvented) and boasts exceptional weld strength due to the UPVC wall thickness.
The upper section of the external wall offers a ribbed section to give improved adhesion to a variety of waterproofing systems and can be fixed to a flat or inclined roof structure.
This range can be used with either a double, triple or quadruple skin polycarbonate rooflight and can also be supplied with a factory-fitted, argon-filled double glazed glass rooflight to further improve U values.
Our 290mm range of UPVC kerb is available in a range of ventilation, security, opening and access options.
The 290mm Range is available in a range of ventilation, security, opening and access options:
Unvented
Product code: NLS300
A fixed rooflight and unvented kerb. This product should be used for areas that require natural light only.
Hit and Miss Titon Vents
Product code: NLS320
This product offers manually operated ventilation via a sliding mechanism mounted internally to the kerb. The vents are opened and closed as required by hand or by pole. The vents can be installed on 2 or 4 sides of the kerb. This product is ideally suited for areas that do not require a high volume of ventilation.
Rotary Vents
Product code: NLS330
Rotary vents offer manually operated ventilation via a rotating internal vent which allows the user to open and close the vent as required by hand or by pole. The vents can be installed on 2 or 4 sides of the kerb. This product is ideally suited to areas that do not require a high volume of ventilation.
SecuriLight
Product code: NLS600
To fulfil the requirements of security conscious rooflight applications the ‘SecuriLight’ offers additional defence against intrusion through use of a continuous polyester powder coated perimeter clip to the external flange of rooflights. The perimeter clip removes the need for visible fixings to secure the rooflight to the kerb. Once installed the clip cannot be removed even by the use of hand tools by a potential opportunist intruder.
This product is certified PAS24: 2012, annex C.4.3 due to enhance security performance. An additional option of a high tensile burglar bar grid is available and can be integrated into the kerb assembly under the rooflight if required.
Wormgear
Product code: NLS340
A brass telescopic winding mechanism is mounted internally to a 40mm high UPVC lifting frame which is fitted with galvanised steel reinforcement bars. This mechanism allows the user to remain at ground level and operate the unit with a winding rod. Wormgear rooflights offer a higher level of ventilation and can be opened up to approximately 300mm.
Access Hatch
Product code: NLS350
An opening hatch that utilises 2no gas rams to assist opening, mounted internally to a 40mm high UPVC lifting frame which is fitted with galvanised steel reinforcement bars. The hatch will open to between 80-90 degrees to give ease of access to floor level. The Access Hatch is available with Brighton Catch, Hasp and Staple or key operated locking mechanism.
Chain Motor
