The primary hazard is **thermal shock**: applying warm or room-temperature cleaning solution to cold glass creates a temperature differential that stresses the pane at its edges and existing micro-defects. This project provides: - **Thermal shock risk calculator** — five-variable assessment of glass surface temperature, delta-T, and risk band - **WFP freeze feasibility calculator** — evaluate whether a water-fed pole cleaning solution will remain fluid at operating temperature - **Reference datasets** — glass thermal tolerance thresholds and WFP solution freeze-point curves for 22 configurations each - **Multi-language implementations** — Python (PyPI), JavaScript (npm), Rust (crates.io), Ruby (RubyGems), Elixir (Hex.pm), Java (Maven Central), PHP (Packagist) --- Quick Start ----------- [](#quick-start) ### Python [](#python) ``` pip install residential-window-cleaning-2026 ``` ``` from residential_window_cleaning_2026 import ( GlassType, assess_thermal_shock_risk ) result = assess_thermal_shock_risk( glass_type=GlassType.DOUBLE_IGU_LOWE, ambient_temp_c=-8.0, wind_speed_kmh=15.0, sun_factor=0.0, # north-facing, shade solution_temp_c=18.0, ) print(result.risk_band.value) # 'low' print(result.advisory) ``` ### CLI [](#cli) ``` rwc-assess thermal-shock \ --glass-type double_igu_lowe \ --ambient-temp -8 \ --wind-speed 15 \ --sun-factor 0 \ --solution-temp 18 ``` ### JavaScript [](#javascript) ``` npm install @veronica_caledon/residential-window-cleaning-2026 ``` ``` const { assessThermalShockRisk } = require('@veronica_caledon/residential-window-cleaning-2026'); const result = assessThermalShockRisk({ glassType: 'double_igu_lowe', ambientTempC: -8, windSpeedKmh: 15, sunFactor: 0, solutionTempC: 18, }); console.log(result.riskBand); // 'low' ``` --- Glass Types Supported --------------------- [](#glass-types-supported) KeyDescription`single_annealed`Pre-1990 single-pane annealed glass`single_tempered`Single-pane tempered (shower doors, entry glass)`double_igu`Standard double insulated glass unit`double_igu_lowe`Double IGU with Low-E coating (post-2000 residential)`triple_igu`Triple-pane IGU`triple_igu_lowe`Triple-pane with Low-E — common in post-2010 Northern Ontario builds`laminated`Laminated safety glass (sidelites, skylights)`wired`Wired glass — lowest thermal shock tolerance--- Datasets -------- [](#datasets) Published on Hugging Face at `veronica_caledon/residential-window-cleaning-2026`: - **`glass_temp_risk_thresholds`** — thermal conductivity, safe surface temperature minimums, and maximum delta-T by glass type (22 configurations) - **`wfp_solution_freeze_curves`** — freeze point, viscosity, contact angle, and streak risk for 22 WFP cleaning solution formulations --- Northern Ontario Context ------------------------ [](#northern-ontario-context) North Bay and Sudbury experience freeze-thaw transition periods in March–April during which exterior glass surfaces commonly reach −10°C to −20°C overnight, while daytime air temperatures climb to +2°C to +8°C. Low-E coatings — standard in post-2000 Ontario residential construction — reduce heat transfer from indoors, keeping outer panes colder than ambient during morning hours. The cleaning window for each day is narrow: too early and glass is too cold; too late and afternoon winds increase solution evaporation and streak risk. This calculator helps identify that window precisely. --- Compliance References --------------------- [](#compliance-references) - **WSIB O.
