Fiber Cement Siding

As global leader in fiber cement siding, James Hardie manufactures products unique to it’s market in Europe, Australia, New Zealand, and the USA. My structure seeks a modern aesthetic. If I had a choice I would have selected a Scyon system of exterior cladding or a EPDM tape option for a genuine rainscreen siding, but in the USA, we have fiber cement vertical panel and aluminum reveal to adapt to the limited products available.

Fry Reglet, Tamlyn, and Easy Trim Reveals offer fiber cement reveals. Each manufacture similar profiles to encapsulate the 5/16″ fiber cement panel on all edges to shed water away from the building, but only Easy Trim Reveals allows an easier installation of aluminum trim and a water management strategy, not just decorative trim. I worked with a handful of lumberyards for pricing and availability of products, and expect a delivery of panels, fasteners, trim, and tools soon.

Many firms manufacture fiber cement panels from the Japanese Nichiha and KMEW, to domestic Allura and GAF. Many of these cladding systems offer amazing textures and installation systems, but my walls are structural insulated panels, and few vendors are willing to warrant installations on this building system. James Hardie has an installation on sheathing exclusively with the correct fastener length in their Evaluation Report.

My final exterior cladding selection includes a Henry Blueskin VP100 Water Resistive Barrier, plywood battens for a 11 mm rain gap, HardiePanel in Colorplus Monterey Taupe JH40-20, SFS TW-S fasteners, and Easy Trim Reveals in clear anodized color. I had some primed Soffit panel that I needed to color match to the Monterey Taupe, and Valspar Paint customer service shared the recipe with my local paint store. For some reason Easy Trim Reveals do not offer a window flashing profile, so I had to order a Tamlyn XtremeTrim just for that part of the project.

There are many gaps in the storytelling of the dark green micro home addition. As history is revised, it’s also best to start fresh, and today is a good time to start. The foundation waterproofing system from Epro is finally in place, along with the removal of the last concrete form board. The first floor is secure with 4×10 sill plates, and the backfilling has begun. After a few hours of moving earth, I remembered a needed to research an acceptable thermal barrier for my mini-basement, or crawlspace.

Typically crawlspace construction is vented to the outside, separating the living space from the condition space above. I am trying the sealed crawlspace technology, which make the space more a basement, which then requires 1/2″ gypsum board or equivalent to protect the structure from fire. Usually a foundation wall might have an ignition barrier, but I need either gypsum or a portland cement barrier for protection. I considered for a few hours a EIFS but they are too labor intensive for an area that should not see much moisture or weather events. I decided on a stucco parge coating.

I looked up the inventory and pricing at the local home store, and going premixed or component (plastic cement and plaster sand) came out nearly the same price. I headed over to Lowe’s in Pacoima, but they could not find an entire pallet of 80 lbs Quikrete Scratch and Brown Base Coat, so I had to go the Burbank location. The order desk closed at 6:00 PM, and it was already 6:20 PM, so I headed over with my item numbers to customer service. The process took too long, as one of the perquisites of using a Lowe’s Commercial Account is considerable discount in home delivery, which they did not now about. I had to get a manager’s approval. Instead of the usual $79 fee, it drops to $20 an order. If one is a member of NAHB, that delivery price is zero! I did not get home until 7:40 PM, but I did have time to sign up for the Lowe’s affinity card, called myLowes, which will help track my purchases.
