Editorial method 2.0.0

How this directory reaches its conclusions

The directory combines declared editorial ratings, deterministic use-case weights, source-scoped factual claims, and clearly labeled editorial synthesis. Advertising and affiliated-product status are excluded from ranking inputs.

What this means for readers

Help readers compare covering mechanisms and conditions with scoped evidence. Educational comparison guidance for window coverings. It is not a product certification, installation instruction, or compatibility approval.

Exclusions: Product certification; Installation approval; Universal compatibility claims; Unsupported prices or reviews.

Taxonomy and dimensions

Twenty governed treatment types with category-specific mechanisms.

Upfront Affordability, Blackout Potential, Child-Safe Configuration Availability, Cleaning Ease, DIY Installation Ease, Durability, Smart Ecosystem Breadth, Glare / UV Control, Insulation Potential, Large-Opening Suitability, Adjustable Light Control, Moisture Resistance, Integrated Motorization Availability, Architectural Permanence, Pet Resistance, Closed Privacy, Repairability, Retrofit Automation Availability, Specialty-Shape Flexibility, Clear View When Open.

Formula parity

effectiveScore = rating when Weight >= 0; otherwise 6 - rating.

weightedAverage = sum(abs(Weight) * effectiveScore) / sum(abs(Weight)).

score100 = ((weightedAverage - 1) / 4) * 100.

Negative weights reverse the rating as 6 minus rating. Equal scores retain deterministic source order and are shown as alternatives. Missing ratings are not invented; a ranked record must have a complete governed matrix.

Fit labels: Excellent 80–100; Strong 60–79; Reasonable 40–59; Conditional below 40.

Evidence and confidence

  1. Government safety and energy guidance
  2. Standards and certification bodies
  3. Official manufacturer technical documentation for the named product
  4. Directory editorial synthesis, labeled as such

Manufacturer documentation is labeled and scoped to the named product. Editorial synthesis is labeled and never presented as third-party verification.
