A Dream for Contractors
Contractors and builders appreciate the ease of installation of ThermA Siding. It’s double sided and perfectly profiled in V-joint and nickel gap. It’s up to 30% lighter in weight than regular wood siding. Expansion joints aren’t necessary. ThermA Siding has a far superior grain structure than cedar, isn’t dull like cement or composite siding, isn’t knotty, yellowish or unsightly like Scots Pine, won’t split during installation and is easier on tools as compared to Brazilian hardwoods.
