Architrave moulding forms attractive borders surrounding the interior door and window frames. Complementing the frames with elegantly rounded edges, architrave complements a room's style with natural shadow lines and profiles. The trim adds polish to rough openings. Precision-milled architrave boards offer paint-grade craftsmanship beyond basic caulking and putty around casings. Tightly wrapped joints and mitres display quality workmanship matching the doors and windows within. Modern streamlined profiles and classical ornate curves project distinctly different impressions. From a practical perspective, quality wood or MDF architrave trim conceals small wall cracks and imperfections at window corners. Gaps get masked off with long clean lines rather than just filler compounds alone. The trim moulding also enables easier dusting and repainting of wall edges.
