Best for homes seeking a authentic vintage look with modern safety. These fiber cement shingles mimic old asbestos siding while eliminating asbestos exposure. The UL ANS/UL723 classification and non-combustible ASTM E136 rating provide a safety edge for fire-prone areas. Durable against warping, rot, UV damage, and termites, they maintain their texture and appearance across seasons. Best for historical-style repairs or new builds aiming for a classic texture without hazardous materials. Caution: installation may require precise alignment to preserve the vintage pattern.

TruCraft Raised Panel Pilaster Sets, PVC

TruCraft Pilaster with Capital and Base

Best for architectural details and customizable elevations on modern homes. These 4″ wide x 82″ high PVC pilasters come in pairs with a standard capital and base, and the height can be trimmed up to 6 5/8″. They suit facades needing substantial vertical accents without heavy woodwork. PVC construction resists moisture and can be painted to match siding. Choose this if your project calls for visible, plinth-like features that mimic carved stone or wood details. Limitation: PVC may feel less authentic to historic materials at very close inspection.

They tolerate a wide temperature range (40°F to 130°F) and suit both indoor and outdoor use. They are ideal for covering cracks, holes, or blemishes on siding boards without requiring professional tools. A caution: patches may be more conspicuous on highly textured surfaces or when color matching is imperfect.

Best for a straight-edged, vintage look with durable performance.

The profile emphasizes a vertical, striated surface for a bold, classic appearance while offering resilience to weather, warping, and termites. Choose this if you want a longer panel height for fewer seams. Limitation: larger shingles may demand careful spacing during installation to achieve uniform lines.

Buying Guide: Key Considerations For H Molding And Siding Accessories

  • Material and safety: Fiber-cement options provide fire resistance and durability, while PVC and composite materials excel in moisture resistance and ease of maintenance. Consider asbestos-free certifications for safety and long-term durability.
  • Style and texture: For authentic vintage looks, select shingles with textured surfaces and patterns that resemble historical siding. For modern or column accents, choose pilasters and mounting blocks that match your siding profile.
  • Installation needs: Some products require precise alignment or trimming, while mounting kits offer built-in electrical boxes and easier, tool-light installation. Plan for weather conditions during installation.
  • Compatibility: Check chipboard thickness, lap widths, and height requirements. Ensure pilasters, shingles, and blocks fit your existing siding and architectural style.
  • Maintenance and color: Paintable surfaces require color-matching planning. Pre-primed options can shorten finish work, while darker colors may influence heat absorption.
