Why chosen: The R&R design simplifies laying, reduces measurement errors, and provides a ready-to-paint surface.

Buying Guide: Cedar Siding And Related Options
What to consider when choosing pre primed cedar siding and cedar-like products:
- Project type: For full-wall siding, prioritize primed shingles or panels that provide adequate coverage per carton.
- Exposure and layout: Check exposure (inches) and double coursing needs to estimate number of cartons.
- Surface finish: Primed cedar offers paint-ready surfaces; sanded versions provide a softer finish but may wear differently over time.
- Maintenance expectations: Vinyl options require less upkeep but may limit color customization or require expansion gaps with temperature changes.
- Warranty and codes: Ensure compatibility with local building codes and any required warranties for exterior wood or vinyl products.
- Ease of installation: Rebutted and Rejointed (R&R) designs can simplify alignment; check for grooving, notch patterns, and locking systems for vinyl.
- Aesthetic goals: Real cedar textures and light-block accents offer authentic warmth; consider a mix of full siding with decorative cedar blocks for interest.
