“The only LPCB certified insulated gutter system available on the market. The system is lightweight and available up to 8m long for quick installation”

ApplicationOur Membrane Lined Insulated Gutter is suitable for boundary wall, valley and valley-hip gutter applications for most building types. For further information, rainwater drainage calculations and standard construction details please contact the Kingspan Technical Services Department.

Membrane Lined Insulated Gutters are available in customer-defined custom lengths up to and including 8m. Note that lifting eyes and tackle can be provided on request for ease of mechanical handling.*

A range of gutter components are available made to order, including internal and external corners, stop ends, T-sections, sumps, overflows and weirs.

Notes:* Lengths over 7.2m may incur additional transport charges, please refer to Sales.

** Based upon 1m2 of top sheet, insulation and liner.

*** The U-value has been calculated using the method required by the appropriate National Building Regulations.

System Benefits LPCB certified to LPS 1181 Grade EXT-B and FM approved PIR insulation core.

Guaranteed for structural and thermal performance for up to 15 years (IKO Armourplan 0.6mm and Sika-Trocal 0.8mm membranes) and for up to 25 years (IKO Armourplan 1.2mm and Sika-Trocal 1.2mm membranes).

Available in lengths up to 8m maximum. Longer lengths mean less joints, less welding and less risk plus faster installation.

U-values ranging from 0.67W/m2K (30mm thick) to 0.21W/m2K (100mm thick) - fully compliant with the appropriate National Building Regulations.

Provides pre-melt drainage in the event of snow fall and ice formation, facilitating drainage under winter conditions.

Lightweight and easy to install. A typical 60mm thick gutter with 1200mm girth weighs just 15kg per linear metre.

IKO Armourplan membrane is available in Mid Grey (RAL 7046), whilst Sika-Trocal membrane is available in either Light Grey (RAL 7047) or Slate (RAL 7015).

Factory-fitted outlets on request, including customers own syphonic outlets.

Typical Applications

Boundary Wall Gutter without Parapet

Our boundary gutters have been fully tested for non-fragility when simply supported as shown and are suitable to be used as a walkway, with a maximum sole dimension of 1000mm. Wider soles will require additional support.

Typical Dimension Ranges

Boundary Gutters are inboard of the building envelope, often behind a parapet or feature eaves detail. They are normally simply supported from the eaves roof purlin and by a single continuous support under the vertical leg.

It is normal for a boundary gutter to be designed for pre-melt drainage in order to reduce potential snow loading and minimise potential risks during maintenance.

Stop ends, weir chutes and overflows are important features of a boundary gutter, as are T-sections and interfaces where building elements meet.

Valley Gutter

Typical Applications

Valley gutterInsulated roof panel

Outlet

Valley Gutters must be correctly designed to ensure adequate capacity and outlets to drain the adjacent roof slopes. The use of symphonic drainage is common for very large roofs where it may otherwise be difficult for a gravity drainage system to accommodate storm design.

It is normal for a valley gutter to be simply supported from the two roof purlins adjacent to the valley.

Weir chutes and overflows are particularly important for valley gutter applications.

All jointing kits supplied complete with the gutter, including rivets and jointing membrane, reducing the need to source from additional suppliers. Additional jointing strip and other components are available on request.

On request lifting eyes can be factory fitted to enable easy mechanical handling on site by crane or other lifting equipment. Shackles and eye-bolts can be supplied as necessary.

Our valley gutters have been fully tested for non-fragility when simply supported as shown and are suitable to be used as a walkway, with a maximum sole of 850mm. Wider soles will require additional support.

Note that when using 0.6mm membrane it may be necessary to use additional protection to the membrane if using the gutter as a walkway, in order to ensure no damage occurs to the membrane coating.

Kingspan SupportThe Kingspan Technical Services Department offer technical advice and support throughout the design and construction process. From the undertaking of roof drainage calculations to optimising the gutter size, outlet size and positions, to providing thermal junction values for whole building calculations, we can help ensure that your building complies with the building and thermal regulations. NBS format specifications are also available.

Our Field Service Engineers offer free contractor training on the installation of new and existing products at our specially designed facilities at Holywell, North Wales. They also offer a site inspection service throughout the construction stage and can offer advice on mechanical handling solutions.

Gutter AncillariesWeir Chutes, Hopper Boxes, Sumps, Tapered Outlets, Tell-tales and Overflows are all standard ancillary items essential to many gutter systems.

These items are available PVC dipped on request to ensure that installation on site is as simple as possible.

Membrane detailing strip is available from stock to assist in the site fitting of ancillary items.

Alternatively most items can be factory fitted, including syphonic outlets (customer own supply).

For further information please contact a member of the sales team.

Customers own syphonic outlets can be factory fitted on request, saving time on site.
