The 15/32-in X 4-1/4-in X 144-in colonial 620 base interior polystyrene moulding cuts, installs and fills just like wood and MDF moldings. The Trimfinity advantage is it's more durable, resistant to moisture, mold, mildew and pests. Our mouldings are also better for the planet, made of at least 90% recycled polystyrene. Use as is with our pre-finished white surface or easily paint.
