1. Weight and Installation

Acrylic: The Lightweight Champion

- Low Density: Acrylic is about half the density of glass, making acrylic pool windows much lighter than their glass counterparts of the same size.

- Easy Installation: The lighter weight means a simpler and safer installation process. Workers can more easily handle and position acrylic panels, reducing installation risks and labor intensity.

- Transportation Advantage: Due to its lightweight, transporting acrylic pool windows usually costs less than glass. This is particularly beneficial for projects requiring long-distance transportation.

- Structure-Friendly: The lightweight nature puts less pressure on building structures, which is especially important in older buildings or those with limited load-bearing capacity.

- Maintenance Convenience: If future maintenance or replacement is needed, lightweight acrylic panels are easier to handle, reducing operational difficulties and potential safety risks.

Glass: The Traditional Heavyweight

- Heavier Material: Glass has about twice the density of acrylic, meaning glass pool windows of the same size will be much heavier.

- Installation Challenges: The heavier weight may require more manpower and specialized equipment for installation, increasing complexity and cost.

- Transportation Considerations: Due to its greater weight, transportation costs for glass pool windows may be higher, especially for large-sized windows.

- Structural Requirements: May require reinforced building support, especially for large-area glass pool windows, potentially increasing overall project complexity and cost.

- Maintenance Difficulty: Replacing or repairing large glass panels may be more challenging than handling acrylic panels, requiring more specialized equipment and techniques.

2. Thermal Insulation Performance

Acrylic: The Heat Keeper

- Excellent Insulation: Acrylic has a lower thermal conductivity than glass, better preventing heat loss.

- Energy Efficiency: In cold seasons, acrylic pool windows can better maintain pool water temperature, reducing the energy consumption of heating systems.

- Comfort Enhancement: Due to reduced heat loss, pool water temperature remains more stable, improving swimmers' comfort.

- Condensation Reduction: The excellent insulation properties can also reduce condensation, improving visual clarity and reducing potential moisture damage to surrounding structures.

- Extended Seasonal Use: In colder climates, superior insulation properties can extend the pool's usable season, allowing you to enjoy your pool for longer periods throughout the year. 

Glass: Requiring Special Treatment

- Basic Insulation is Poor: Regular glass has inferior insulation properties compared to acrylic, potentially leading to more heat loss.

- Special Treatment Options: Low-emissivity (Low-E) glass or double/triple-pane glass can be chosen to improve insulation, but this increases cost.

- Lower Energy Efficiency: Without special treatment, glass pool windows may lead to higher energy consumption, especially in seasons when pool heating is necessary.

- Temperature Fluctuations: Due to poorer insulation, glass pool windows may cause water temperature to be more susceptible to external temperature changes.

- Condensation Issues: In environments with large temperature differences, glass surfaces are more prone to condensation, potentially affecting visual effects and the surrounding environment.

3. Safety and Impact Resistance

Acrylic: Safety Pioneer

- High Impact Resistance: Acrylic has higher impact resistance than regular glass and is not easily broken.

- Safe Breakage Pattern: Even in extreme cases of breakage, acrylic doesn't form sharp fragments, greatly reducing the risk of injury.

- Child and Pet Friendly: Due to its safety features, acrylic is particularly suitable for families with children and pets.

- Seismic Performance: In earthquake-prone areas, acrylic's elasticity and impact resistance can provide better seismic protection.

- Long-term Safety: Acrylic maintains its safety features better than regular glass over time.

Glass: Safety on Demand

- Regular Glass Risks: Untreated glass has lower impact resistance and may form sharp fragments when broken.

- Safety Glass Options: Tempered or laminated glass can be chosen to enhance safety. Tempered glass breaks into small granules, while laminated glass stays in place even when shattered.

- Situational: Safety depends on the type of glass and treatment method chosen.

- Regular Inspection Needs: Glass may require more frequent safety checks, especially in high-pressure or high-use environments.

- Replacement Considerations: Once cracked or damaged, glass pool windows may need immediate replacement to maintain safety.

4. Light Transmission

Acrylic: Light Conduction Advantage

- High Transparency: Acrylic can achieve up to 92% light transmission, higher than most glass.

- Clear Underwater Vision: More natural light penetrates the water, providing clearer and brighter underwater views.

- Color Reproduction: High light transmission helps better reproduce true colors in the water, making pool landscapes more vivid and appealing.

- Energy Benefits: More natural light entering indoor spaces can reduce the need for artificial lighting, thus saving energy.

- Plant Growth: If there are aquatic plants in the pool, acrylic's high transparency is beneficial for their growth and health. 

Glass: Traditional Transparent Choice

- Good Transparency: Regular glass has about 88% light transmission, slightly lower than acrylic but still providing good visual effects.

- Slight Distortion: Glass may cause slight distortion of underwater scenes, which in some designs might be viewed as a unique aesthetic feature.

- Special Treatment Impact: Some special treatments (such as low-emissivity coatings) may slightly reduce glass's light transmission.

- Stability: Glass's light transmission performance remains relatively stable after long-term use, less affected by environmental factors.

- Diverse Options: Different types of glass (such as ultra-clear glass) can be chosen to optimize light transmission performance.
