Nicoll gutters are made of TECHTAN®an exclusive and ultra-resistant synthetic material. This material not only contributes to the long-lasting protection of the building, but also enhances its aesthetics.

Nicoll gutters made of TECHTAN® have a 30-year warrantybeing the first synthetic material on the market to offer this coverage.

Different solutions for each installation

OVATION

OVATION® LG28 and LG38 in TECHTAN®.

Discretion and hydraulic performance Available in two models, LG 28 and LG 38. The OVATION® gutter system in TECHTAN® , with its sober and fluid design, adapts to all architectural styles. The OVATION LG38 model is the highest flow gutter on the market (maximum flexibility with a high flow rate). OVATION guarantees optimum capacity and flow rate. With a single outlet, the LG 28 model can service 65 m² of flat roof and the LG 38 up to 100 m².

Serie Circular

Circular Series LG25 and LG33

It has a semicircular design that offers optimum capacity and evacuation speed. In addition, thanks to a wide range of fixing hooks, it is possible to install it in cases where the tile ends beyond the box structure. The Circular Series guarantees optimum capacity and flow rate. With a single outlet, the LG 25 model can service 65 m² of flat roof and the LG 33 up to 100 m².

Elite-Alfa series

Elite-Alfa LG30 series

Characterized by a high resistance to shocks thanks to its double-walled internal reinforcement, it adapts to two types of downspouts: circular or rectangular. It adapts to two types of rainwater downspouts: circular or rectangular. Available in two colors: white and sand. The Elite-Alpha Series guarantees a capacity and a flow rate from 65 m² to 70 m² depending on the model of downspout and pipe.

Nicoll patented technology, manufactured according to European standards.

Our TECHTAN® range is made to meet 100% of your needs.

Profiles and accessories comply with NF EN 607. The hooks comply with the NF EN 1462 standard .

They meet the requirements of European standards: NF EN 607: profiles and fittings for gutters; NF EN 1462: hanging hooks for gutters (PVC or metal).

Invisible hook

With its completely invisible hook, the NICOLL gutter system is more discreet and aesthetically pleasing.

The hook supports a load of 50 kg ( EN 1462 class L). The free sliding between the hook and the profile facilitates installation and controls expansion.

How to size your gutter system correctly?

The correct sizing of the rainwater drainage system is essential to ensure its efficiency and durability. Below, we explain the key steps:

1. Evaluate the type of roof.

The design of the roof influences the installation:

Single roof with free edge
Gable roof
hipped roof
Roof with blocking at both ends

Identify your pluviometric zone.

Consult the isohyets map to know the average annual rainfall intensity in your area. This will allow you to calculate the rainfall intensity (I) required for sizing.

^{*See more information in the documentation at the bottom of the page.}

3. Calculate the collection area

Determine the roof plane with the largest area in horizontal projection.
Example: Roof 10 m x 8 m = 80 m².

4. Select the right model

Depending on the rainfall intensity and the roof surface, make your choice:

The geometry of the gutter
The diameter of the downspout
The number of downspouts required

^{*See more information in the documentation at the bottom of the page.}

5. Consider the length of the sections

If the section exceeds 12 linear meters, it is necessary to foresee dilatations.
Use expansion downspouts or special joints to avoid stresses in the system.
