Evidence Scope

No moisture-performance or health comparison is made here. Caramella's current policy specifies ENF plywood for carcasses unless a client specifies otherwise.

Quick Answer

This page provides a cost-comparison framework only; it contains no completed local analysis or system ranking.

Cabinet System Costs: A Comparison Framework

Executive Summary

This page outlines how a property owner could compare cabinet-system costs using project-specific quotes and documented maintenance records. It publishes no local cost, durability, or replacement-cycle findings.

Plywood, HDHMR, and aluminum-frame systems are comparison categories here, not a statement that Caramella supplies every system.

Claim Labeling Rules

  • Label as measured only when the project cost or maintenance record is identified.
  • Label as cited only when the rate, standard, or supplier document is identified.
  • State model assumptions and show how they affect any calculated output.

Research Question

Which cabinet system minimizes 10-year total cost after accounting for installation, maintenance, defect risk, and replacement events?

Possible Analysis Steps

  1. Build cost library (installation, maintenance, repair, replacement).
  2. Estimate failure probability by system and environment.
  3. Compute discounted 10-year cost per scenario.
  4. Perform sensitivity analysis for uncertainty ranges.

Primary Endpoints

  • tco_10y_bnd
  • maintenance_share_percent
  • failure_cost_share_percent
  • break_even_year_vs_baseline

Assumptions

  • Any discount-rate, inflation, or usage scenarios would need to be stated before analysis.
  • Project-specific dimensions, selections, and use patterns can differ.

Limitations

  • Market prices and labor rates shift over time.
  • Any future failure-rate estimate should disclose its source, sample, and observation period.

Evidence Status

This is a proposed comparison framework. No local cost dataset or independently validated results are published here.

What This Does Not Prove

  • Exact project quote for any single home.
  • Future price certainty beyond modeled scenarios.
