The PVC Best cornice gutter has a molded shape of dimensions 122×97 mm which is equivalent to a development of 30 cm. Good to know: the area served by the gutter profiles and descents increases if the slope is higher. Thus, it goes to 70 m2 for a gutter of 25, and 200 m2 for a gutter of 33, if the slope is doubled to 10 mm/m.

Installation a PVC gutter
After having chosen the developments of its gutters and descents in PVC according to the principles described above, the second rule is to respect a regular slope of 5 mm / m minimum. Good to know: for better removal of rainwater, the overflow of the cover must cover 1/3 of the width of the gutter profile.
First, please determine the position of the hook furthest from the descent of the gutter. To do this, you can start from the edge of your roof and measure 30 cm. Note the location of this first hook with a grease pencil (or carpenter’s pencil). You should also consider Gutter Cleaning Wellingborough services.
Using a chalk line, draw a horizontal line on the edge board, respecting the famous and essential slope of about 5 mm per meter between the birth and the last hook. Make markings on this line every 40 cm to indicate the locations of the other hooks.
Good to know: we must not forget that the gutter hooks, in order to optimize the breaking strength of your gutter system, must also be placed 5 cm on each side of the births, angles or even junctions.
The installation on the roof strip is the simplest type of installation. Insert the gutter profile first into the groove of the PVC hook and introduce the bead of the gutter in front of the hook housing.
If you do not have a headband two possibilities are available to you. Fixing on the top of the chevron with straight shafts or fixing on the side of the chevron with scalloped shafts.
After installing the shafts on the roof wall, adjust the inclination according to the slope of the roof. The height of the PVC hook can be adjusted at the slot to obtain a regular slope of 5mm/m. For professional gutter services visit Gutter Cleaning Wellingborough.
