Key Ingredients
•
Wood fiber: 100% northern hardwoods which includes maple
maple, beech
beech, oak
and other species. All wood comes from an area within a 150 mile radius of
the production facility and no old growth wood is used.
•
Zinc borate: EPA-registered
g
biocide and a naturally
y occurring
g earth
chemical that is environmentally safe and ensures protection against
termites.
•
Phenolic resins: Durable, heat and moisture resistant resins that create
moisture

d Th
There iis no added
dd d urea
formaldehyde; any emissions for the process or the product itself are the
same as background levels found naturally in the environment.
•
Wax: For moisture resistance.
•
And other proprietary ingredients.
Treated Wood Composite
Manufacturing Process
Manufacturing process was created solely to make exterior trim.
trim
1. Ingredients are combined and formed into a thick fiber mat.
2. Fiber mat is loaded into the sealed cavity press.
3 Steam is injected into the fiber mat; steam escapes the mat
3.
evenly from the center to the periphery of the board.
Treated Wood Composite
Attributes
• Best value
• Resists moisture, rot and termites
• Reversible; more authentic wood
texture
e ue
• Easy to handle, machine, cut and nail
• Won't check, split or crack
• Cuts consistently due to uniform
product density
• Broader product line
• 50-year warranty
• MiraTEC trim is the first and only wood
composite trim to earn an evaluation

Drawbacks
• Heavier than most wood
species
• Tougher on saw blades than
wood due to being an
engineered products (resins)
• Cannot be installed below
grade

Ingredients
•
Wood fiber
•
Environmentally friendly phenolic resins
•
Wax
•
Zinc borate in some products (method of addition of this
earth chemical varies; rate of retention – impacting total
product performance – if zinc borate varies)
Manufacturing Process
Hardboard Trim
1. Fibers + resin = form a mat
2. Inserted in an open press. The
two boards are pressed
between an upper and lower
platen. This may create a
product with variable density
3. Product is laminated together
into trim thickness outside of
the press, prior to cutting
4 Process was created for the

Treated Wood
Composite
• Independent third-party test results
shows treated wood composite trim
resisted moisture the best and had the
lowest percentage of residual or
remaining thickness swell.
• Thickness swelling is caused by the
breakdown of the resin bonds within the
trim board, which then leads to more
water absorption.
Hardboard Trim
Attributes
• Warranty coverage varies
from 10 to 50 years by brand
• Easy to use, like wood
Drawbacks
• May delaminate
• Product may have variable
density due to manufacturing
process
• Poor performance history;
significant issues with edge
swell and rot
• Less authentic wood grain
texture
• Warranty may exclude hail
hail,
termite damage and edge swell

– The most commonly used process is Free Foam, which features these
ingredients: PVC polymer, inert fillers, heat stabilizers, lubricants and
process aids such as acrylic compounds
– Products made using the Celuka process feature a range
of ingredients, including PVC and proprietary mixtures
