Use And Care Manual
 MIRATEC VS PRIMED WOOD TRIM
 MIRATEC VS HARDBOARD/FIBER AND OSB TRIM
>> Resists moisture, rot and termites.
>> Reversible with clear cedar wood grain 
texture on one side and smooth on  
the other. 
>> Easy to handle, machine, cut and nail.
>> Won’t check, split or crack. 
>> Cuts consistently due to uniform 
product density. 
>> Primed with an ultra-low VOC primer 
containing a mildewcide.
No other trim 
performs like MiraTEC.
• MiraTEC is not laminated. 
• MiraTEC has greater moisture resistance which means 
better long term performance. 
• MiraTEC performs up to 9 times better in Weatherability 
Testing, which evaluates a product’s ability to withstand 
exposure to the elements over time. See chart at right.
• MiraTEC has none of wood’s frustrating 
drawbacks.
• MiraTEC doesn’t require significant 
maintenance and replacement, because it 
resists moisture, rot and termites. Primed 
wood may be treated, but many do not offer 
rot and termite protection.
• MiraTEC is a more advanced, engineered 
material.
• MiraTEC offers consistent density.
• MiraTEC won’t warp, split or check over time.
• MiraTEC is one solid piece. Primed wood is 
normally finger jointed to make longer lengths 
and edge glued to make the width - with a 
limited warranty on the glue joints.
IN HEAD-TO-HEAD 
COMPETITION, 
IT’S NO CONTEST.
• MiraTEC has a more authentic wood grain texture. 
• MiraTEC is reversible. 
• MiraTEC is highly resistant to moisture. Independent tests show 
fiber cement absorbs five times more water (ASTM 24 - Hour 
Soak Test). See chart at right.
• MiraTEC is 100% silica free. Cutting fiber cement releases silica, 
a known carcinogen. 
• MiraTEC is not brittle or difficult to stack. 
• MiraTEC is as easy to handle, cut and nail as wood, requires no 
special tools. 
• MiraTEC is available in widths up to 16” and lengths of 16’, 
takes less time and labor to install. 
• MiraTEC is backed by a 50-year limited warranty.  
Most fiber cement has a 15-year limited warranty. 
• MiraTEC costs up to 30% less.
 MIRATEC VS FIBER CEMENT TRIM
• MiraTEC has a more authentic wood grain texture. 
• MiraTEC accepts all shades of paint beautifully. 
• MiraTEC is not prone to thermal expansion. 
• MiraTEC is made from sustainable materials and  
renewable resources. 
• MiraTEC costs up to 50% less.
