Frequently asked questions


Can we glue ceramic, decorative stone or another finish on the panel while using it as a heat-sceen behind a stove?

R: No, because compare to ceramic which is inert, the Finex panel has a dimentional movement with intense heat, like behind a stove.

What is the fire resistance of Finex panels?

R: Finex panels are incombustible according to our ulc-s-114 test. Finex panels have a different fire resistance depending of the construction assembly, so the fire resistance of the panels depends of their use.

Can we groove the panels?

R: Yes, it is possible to groove the ½’’ panel simply with a concrete router.

What differenciates the Finex panels from other fibercement panels?

R: Finex panels are reinforced with synthetic fibers spread through the entire panel, which means it is entirely concrete. Light concrete panels are reinforced with treillage each side and they have ‘fillers’ like sand which make these panels less resistant.

Can we use the ¼’’ panel horizontally?

R: No, the ¼’’ panel is exclusively for vertical use such as siding or ceilling/soffit. For horizontal applications, your silution is the structural ½’’ Finex panel.

Can we use the Finex panel as a shower siding?

R: yes, the Finex panel can be used as a shower siding with a waterproof membrane behind and a water repellent scelant over it.

Is there a thicker panel than the ½’’ panel?

R: No, but the ½’’ panel is as resistant as it gets, there is no need for any extra reinforcement for your projects.

Why do i need to leave an expansion joint between panels?

R: Finex panels are sensible to exterior climat changes or behind a stove and so, it is necessary to leave an expansion joint of 1/8’’ minimum for the panel to move freely.

Why do i need to drill a hole 5/64’’ (2mm) wider than the diameter of the fastener?

R: For the same reason as last question. Because of the natural movement of the panel during freeze/thaw cycles, the panel will expand and move, this is why drilling 5/64’’ (2mm) wider than the fastener is necessary.

Can we glue the panels instead of mechanically fasten?

R: it is always preferable to fix mechanically the panels where there will be temperature changes due to the panel’s expansion.
