Fire Retardant PVC Colonial Door Casing Moulding B1 Grade Anti Termite Rot Proof Interior Decorative Trim 7ft 8ft
Product Overview
The fire-retardant PVC colonial door casing brings timeless architectural elegance together with modern safety and durability standards. The classic colonial profile—with its distinctive stepped design and refined proportions—is precision-extruded from B1 fire-rated cellular PVC with permanent anti-termite and anti-rot protection.
This casing transforms ordinary doorways into design statements while satisfying fire code requirements for commercial, multi-family, and institutional projects. Unlike wood colonial casing that requires skilled carpentry to install and constant maintenance to preserve, this product delivers identical aesthetics with zero maintenance for the life of the building.

Frequently Asked Questions
What makes this different from standard PVC colonial casing?
Three key differences: (1) B1 fire rating suitable for commercial fire-code applications, (2) integrated permanent termiticide (most standard PVC relies solely on being inorganic), and (3) enhanced density for superior fastener holding and impact resistance.
Can I install this with a standard miter saw?
Yes. Use a fine-tooth carbide blade (60-80 teeth for 10" saw). The material cuts cleanly without chipping. We recommend cutting slightly slower than wood for the best finish.
Is the colonial profile available in different proportions?
Yes, we offer the colonial profile in narrow (2-1/4"), standard (3-1/4"), and wide (4-5/8") widths, each with proportionally scaled step details to maintain the classic colonial look.
Does the fire rating affect the paintability?
Not at all. The primed surface accepts all standard architectural paints. The fire-retardant additives are integrated within the PVC matrix and do not affect surface adhesion or finish quality.
