Read and compare garage-door product specifications
Compare the same configured door, not just two brochure headlines. Keep model/options, dimensions, test scope and package inclusions aligned before deciding that one specification is better.

Read and compare garage-door product specifications
Compare the same configured door, not just two brochure headlines. Keep model/options, dimensions, test scope and package inclusions aligned before deciding that one specification is better.
Identify the exact configuration behind each number
A product family can have more than one construction, window package or finish. Record the model/series and chosen options with the brochure revision or current product page. Do not treat the highest number advertised for a family as the figure for every configuration.
Put different kinds of claims in different rows
Dimensions, construction, thermal performance, glazing and written coverage answer different questions. R-value and U-factor are not interchangeable, and a section value does not automatically represent a whole configured assembly. Link to the existing thermal-rating guide for the explanation rather than comparing unlike test scopes in one “insulation” cell.
Separate a specification from an installed promise
A brochure cannot confirm that a product fits the measured opening or that a quoted installer includes the required track, removal and setup. Ask the supplier to mark unknown fields and the installer to confirm fit and scope. A blank supported field is more honest than filling in an industry-looking number from a different product.
Worked comparison: two Classic Steel short-panel constructions
Clopay’s Classic Steel brochure separates 9200 polyurethane and 4300 bonded-polystyrene short-panel models. The table below compares their two-inch solid-section construction using the baseline steel gauge, excluding Black and Ultra-Grain finish options. Each figure comes from brochure page 3, including its section-R-value footnote. Opening size, selected finish/glazing, complete thermal test result, site fit, current written coverage and installed quote still need confirmation.
| Observation or choice | What it changes | What to record |
|---|---|---|
| Model/options | Defines the product being compared | Exact series and selected configuration |
| Dimensions/clearances | Need site and system confirmation | Product document plus measured opening |
| Thermal rating | Compare like test scopes | Metric, configuration and test reference |
| Windows/construction | Options can change the assembly | Chosen glazing/material |
| Package/coverage | Not every brochure feature is a quoted inclusion | Written package and current terms |
| Specification | 9200 short panel | 4300 short panel | Primary source |
|---|---|---|---|
| Section construction | Steel / polyurethane / steel | Steel / bonded polystyrene / steel | Clopay Classic Steel brochure, page 3 |
| Section thickness | 2 inches | 2 inches | Clopay Classic Steel brochure, page 3 |
| Baseline steel gauge | 27; named Black/Ultra-Grain options use 25 | 27; named Black/Ultra-Grain options use 25 | Clopay Classic Steel brochure, page 3 |
| Calculated section R-value | 18.4 | 9.0 | Clopay Classic Steel brochure, page 3 |
| Thermal scope | Door-section value, DASMA TDS-163 | Door-section value, DASMA TDS-163 | Clopay Classic Steel brochure, page 3 |
| Fit, quoted package and price | Not established by this table | Not established by this table | Clopay Classic Steel brochure, page 3 |
This is a source-backed construction comparison, not two approved site orders. Confirm selected dimensions and options before turning it into a purchasing comparison; do not infer whole-door U-factor or energy savings.
