Starting rails

Starting rails : solutions pour l'isolation par l'extérieur

Before fixing the first insulation panel, the façade requires a rigid and perfectly horizontal support at the base of the wall. The aluminium starter rail fulfils this role across the full range of insulation thicknesses available on the market, from 23 to 243 mm, with a simple connection system to cover any length of façade.

Why is a starter rail essential at the bottom of an external thermal insulation cladding façade?

The first line that determines everything else

The starter rail acts as a rigid support for the first row of insulation panels whilst the adhesive sets, preventing any slippage or misalignment that would affect all the rows above. Without it, a simple temporary support cannot guarantee either perfect horizontality or long-term stability: aluminium, which is rigid and corrosion-resistant, retains its shape without deforming under the weight of the panels or deteriorating on contact with moisture at the base of the wall. Once the façade is complete, it continues to play a protective role by marking a clear boundary between the insulation and the ground or the plinth – an area particularly exposed to splashing water and mechanical impact. It is the very first component to be installed on an external wall insulation (EWI) site, even before the first insulation panel, and its initial alignment determines the evenness of the entire façade. Once positioned and secured, it also serves as a visual reference for checking the plumbness of the façade throughout the construction process.

What width of starter rail should I choose, and should I opt for a starter rail or a top rail?

A comprehensive range, from 23 to 243 mm

The range of starter rails covers virtually all insulation thicknesses available on the market, with widths ranging from 23 to 243 mm: simply select the reference that corresponds exactly to the thickness of the installed panel, regardless of the insulation material chosen. The 2.5 m bars are joined end-to-end using a connecting strip or a connector sold in packs of 100, so that they run the full length of the façade without any break in alignment, and simple adjustment shims compensate for any unevenness in a substrate that is not perfectly flat. The top rail is exactly the same width but is fitted at the top, only where the façade changes plane: unlike the starter rail, which is always required at the base of the wall, it is installed only at specific high points on a given building.

Which product is right for your building project?

Fixé en pied de façade, il supporte et aligne la première rangée de panneaux isolants et protège le bas de l'isolant.
La largeur du rail doit être égale à l'épaisseur de l'isolant : un rail de 120 mm pour un isolant de 120 mm, par exemple.
Généralement à au moins 15 à 20 cm au-dessus du sol fini, pour protéger l'isolant des éclaboussures et de l'humidité, sauf si un isolant adapté au contact du sol est prévu en soubassement.
