Boral Nickel Gap siding

airfix | Posted in Green Products and Materials on

Does anybody have experience with Boral Siding? We’ve been looking for a Hardie or Allura siding but can’t find a ship lap style that we are trying to achieve.

Someone clued me into Boral Nickel gap siding but it sounds like it is new and maybe un-tested for the long term. It is made from fly ash and polymers.

The plan is to install it over exterior foam with a rain screen gap made from one by furring strips in zone 6a, a cold snowy climate.

Here are some links I found about the product:

Get the Look: Nickel Gap

Boral TruExterior Trim


Does anybody have any first hand working experience with this or any other links, literature that might be useful?

Cheers

    Steve,
    Here is a link to a GBA article on a project that used Boral siding:
    "Nearing the Home Stretch."

    Here is a link to a GBA article on a project that used Boral exterior trim:
    "Building a Passive House for $163 per Square Foot."

    Here is a link to a Q&A thread on Boral siding:
    "Boral – Proper installation on vertical siding."

    In that thread, Michael Maines wrote, "Boral trim is rated for ground contact, so it won't hurt the product any to be installed directly on the WRB. Best practice is to provide a drainage gap behind the siding, and if you go with your stated wall assembly you definitely want it to be able to dry to the exterior, for which you need the gap. If you read the article Martin linked to, the concerns about your exterior to interior foam ratio should become clear. One thing to be aware of is that Boral shrinks when the temperature drops. Not a lot, especially compared to vinyl or PVC trim, but a lot more than wood."
