Accessories
The right accessories can improve the overall quality of the siding project and make the
job go faster. Some of the accessories Allura recommends include:
Butt Joint Cover (T-covers)—A joint cover is a piece of metal that fits over the
joint between Allura Fiber Cement Siding panels. Joint covers add additional
weatherproofing to the siding and increase its aesthetic appearance.
H-channel—This receiving channel can be used to conceal the edges of vertical
siding panels at the joint.
Off-stud Joiner—Off-stud joiners are used to create a solid backing behind the
joint when the joint is not located over a stud. They hold the bottom edge of the
siding panel in line and provide a seamless appearing joint. Manufacturers include
Simplicity Tool.
Aluminum Moldings/Trim
Moldings and trim can define corners and transitions from one plane to another, or
between dissimilar materials. Manufacturers include:
• Easytrim Reveals • Fry Reglet
• Tamlyn • AMF and Associates
Note: Do not use uncoated aluminum or metal materials with Allura Fiber
Cement Siding.
Backflashing
A flashing strip installed behind the butt joint of lap siding, extending 3” to the left and
right of the joint and 1” over the top of the previous course of siding. Examples include:
Bear Skin
Simplicity Tool Junction Flashing
Painted Aluminum Trim Coil
#15 felt
Check with local building code requirements for acceptable backflashing material.
