Door Frame Pilaster Base
Polure door frame pilaster bases provide a solid visual plinth foundation designed to anchor door casing pilasters and architectural door surrounds. Molded from high-density rigid polyurethane (150-220 kg/m³), these flat-backed bases offer wood-equivalent physical strength and high impact resistance, protecting door surround bottoms from foot traffic, vacuum bumps, and cleaning equipment. Their closed-cell structural composition retains water absorption strictly under 1%, ensuring they will not rot, swell, warp, or foster mold in humid interiors or exterior entrance portals. Rated B2 for fire safety and stable from -100 °C / +80 °C, each base arrives factory pre-primed with white acrylic technical primer. Installation requires dual fastening using polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What is the primary function of a Polure door frame pilaster base?
A door frame pilaster base serves as the flat-backed bottom plinth foundation for door casing pilasters and entryway architraves.
Are Polure door frame pilaster bases load-bearing?
No, Polure door frame pilaster bases are non-load-bearing decorative elements.
What density material is used for door frame pilaster bases?
They are molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like strength and high impact durability.
How are door frame pilaster bases mounted on wall surfaces?
Apply continuous lines of PU assembly adhesive along all joining edges and wall contact surfaces, then secure with countersunk mechanical screws. Fill screw heads with putty, sand, and paint.
Can silicone adhesive be used to mount door frame pilaster bases?
No, silicone adhesive is strictly forbidden because it lacks structural bonding capability. Only polyurethane assembly adhesive paired with mechanical screws must be used.
