When comparing casement and double-hung windows for air infiltration, you'll want to evaluate airtightness test results.
You'll find that casement windows typically outperform double-hung models in weatherstripping effectiveness.
Under wind pressure, casement windows generally maintain a tighter seal, reducing air leakage and improving energy efficiency.
Airtightness Test Results
To truly understand the energy efficiency of different window types, you'll need to evaluate their airtightness test results. These tests measure how much air leaks through the window under controlled conditions. The results are typically expressed in cubic feet per minute (cfm) per square foot of window area.
When comparing casement and double-hung windows, you'll generally find that casement windows perform better in airtightness tests. They often have lower air infiltration rates, typically ranging from 0.01 to 0.03 cfm/sq ft.
Double-hung windows, on the other hand, usually have higher rates, often between 0.10 to 0.20 cfm/sq ft. This difference is due to the design of each window type.
Casement windows use a crank mechanism that presses the sash tightly against the frame when closed, creating a strong seal. Double-hung windows rely on weatherstripping, which can wear over time and allow more air leakage.
However, it's crucial to recognize that these are general trends. High-quality double-hung windows with advanced weatherstripping can sometimes match the performance of casement windows.
Always check the specific airtightness ratings for the windows you're considering to make an informed decision.
Weatherstripping Effectiveness Comparison
Weatherstripping plays an essential role in a window's ability to prevent air infiltration. When comparing casement and double-hung windows, you'll find that casement windows generally offer superior weatherstripping effectiveness. This is due to their design, which allows for a tighter seal when closed.
To understand the weatherstripping effectiveness of these window types, consider the following factors:
- Compression seal: Casement windows use a compression seal, pressing the sash firmly against the frame when closed. This creates a more airtight seal compared to the sliding action of double-hung windows.
- Number of contact points: Casement windows typically have more weatherstripping contact points around the perimeter, reducing air leakage potential.
- Wind resistance: The design of casement windows allows them to use wind pressure to their advantage, pressing the sash more tightly against the frame in windy conditions.
- Maintenance requirements: Double-hung windows may require more frequent weatherstripping replacement due to wear from sliding action, while casement window weatherstripping tends to last longer.
Wind Pressure Performance
How do different window types stand up to wind pressure? When it comes to air infiltration, casement windows typically outperform double-hung windows. Casement windows use a crank mechanism to open outward, creating a tight seal when closed. This design allows them to resist wind pressure more effectively, reducing air leakage.
Double-hung windows, on the other hand, slide vertically and may have small gaps between the sashes, potentially allowing more air infiltration. However, modern double-hung windows often feature improved sealing mechanisms that greatly reduce air leakage.
To better understand the wind pressure performance of these window types, contemplate the following comparison:
| Factor | Casement Windows | Double-Hung Windows |
|---|---|---|
