Unlock Privacy: Acrylic Window Alternatives for Glass Blocks
Glass block windows were once a popular choice to allow light into homes while maintaining privacy. However, advances in window technology have led to new alternatives that offer similar benefits to glass blocks without some of the drawbacks.
One of the most popular replacements for glass block windows is acrylic, also known as plexiglass. Acrylic windows provide an affordable, durable, and customizable solution for those seeking privacy along with energy efficiency and style.
Acrylic/Plexiglass Windows
What is Acrylic/Plexiglass?
Acrylic, or polymethyl methacrylate (PMMA), is a transparent plastic made from acrylic acid. It is manufactured in sheets and molded into shapes for various applications. Compared to glass, acrylic is stronger, more shatter-resistant, and easier to install in custom shapes and sizes.
While not as hard and scratch-resistant as glass, acrylic can be treated with coatings to improve surface hardness. It provides good insulation and sound dampening, though not quite as effective as some glass types.
Benefits of Acrylic Windows
Here are some of the key advantages of choosing acrylic over traditional glass blocks:
- Cost Savings - Acrylic is cheaper than glass blocks.
- Durability - Acrylic is very strong and shatter-proof.
- Design Options - Acrylic can be custom cut and molded into unique shapes.
- Noise Reduction - Acrylic dampens outside noise better than glass.
- Privacy - Opaque and frosted acrylic options allow light in while obscuring views.
- Light Transmission - Clear acrylic maximizes daylight like glass blocks.
- Insulation - Multi-pane acrylic units with gas filling provide good insulation.
Installation of Acrylic Windows
Acrylic windows can be installed in new constructions or used to replace existing glass block windows. The acrylic panes are mounted within weather-resistant frames, typically made of vinyl, wood, or aluminum. Panels can be joined together to create large windows or skylights.
The acrylic panes must be properly sealed within the frame using silicone or rubber gaskets to prevent leaks. Mechanical fasteners and structural support bars may be required for large installations. Proper spacing between panes provides insulation when filled with argon or krypton gas.
Maintaining and Cleaning Acrylic Windows
Acrylic windows require proper care and maintenance. To clean the surface, use mild soap and water or specialty acrylic cleaners. Avoid abrasive sponges and ammonia-based products that can scratch the acrylic.
Use microfiber cloths to prevent minor scratches. For removing scratches, use polishing kits containing very fine grit sandpaper and acrylic polishing compounds. Avoid solvents like acetone or alcohol. Apply UV-blocking wax occasionally to protect acrylic from sun damage.
Other Glass Block Alternatives
Low-E Glass
Low-emissivity (Low-E) glass is regular glass coated with a microscopic metal or metallic oxide layer. This allows light in while blocking UV rays and improving insulation.
There are two types of Low-E glass to improve energy efficiency - Solar Gain Low-E for retaining heat in colder climates and Solar Shield Low-E for reflecting solar radiation in hot climates.
Gas Filled Windows
Filling the space between window panes with inert gases like argon or krypton improves insulation. This reduces heat loss in winter and heat gain in summer. For best results, gas-filled windows are combined with Low-E coatings.
Unique Glass Options
For those who still prefer the look of real glass, there are energy-efficient glass alternatives to traditional glass blocks. These include patterned, frosted, colored, laminated, and tempered glass types that provide visual privacy while allowing light in.
Acrylic and plexiglass windows provide the perfect balance of durability, customization, noise reduction, and energy savings as an alternative to old glass block windows. They bring unique style to any home or building while maintaining privacy.
Other innovations like high-performance Low-E glass and gas filled windows offer exceptional insulation for improved efficiency. With so many options now available, glass block windows are no longer the only choice for privacy, security, and natural light.
