Solar control glass is a specialised type of glazing designed to manage the amount of solar heat and light that enters a building. With increasing awareness of energy efficiency, architects and builders are turning to solar control glass to create comfortable, energy-efficient indoor spaces.

This blog explores the benefits of solar control glass and its significant impact on energy management and indoor comfort.

Quick Navigation

What is solar control glass?

Solar control glass is a smart solution for keeping your home or business comfortable during the sunnier days of spring and summer. Designed with advanced coatings, this type of glass reflects a substantial amount of solar heat while allowing natural light to pass through. [1]

It’s a functional and aesthetic upgrade to standard glass, helping to keep indoor temperatures consistent without compromising on visibility or style.

Here’s how solar control glass works:

Solar control glass is highly effective in managing solar energy. It either reflects or absorbs a significant portion of solar energy before it enters the building, ensuring a comfortable indoor temperature and reducing the need for excessive air conditioning or heating.

In essence, solar control glass is engineered to effectively manage solar radiation, enhancing both comfort and energy efficiency.

Types of solar control glass

Solar control glass is a versatile solution designed to manage the amount of solar heat and light that enters a building, enhancing energy efficiency and indoor comfort. Several types of solar control glass are available, each with unique features and benefits. Let’s explore the main types:

Low-E Glass

Low-emissivity (Low-E) Glass features a thin metallic coating reflecting infrared light, which helps maintain the interior temperature by reducing heat loss during colder months and minimising heat gain during warmer months.

This type of glass is particularly effective in improving energy efficiency by allowing natural light to enter while blocking harmful UV rays and infrared radiation. Low-E glass is ideal for climates with significant temperature variations and helps lower energy bills by reducing the reliance on heating and cooling systems​. [2]

Reflective Glass

Reflective glass has a metallic coating reflecting a significant portion of solar radiation, reducing solar heat gain. This type of glass is often used in commercial buildings and skyscrapers because it enhances energy efficiency and provides a modern, dynamic exterior appearance. [3]

Reflective glass helps control indoor temperatures and offers privacy by reducing visibility from the outside during the day. It is available in various colours and levels of reflectivity, making it a versatile choice for different architectural designs.

Tinted Glass

Tinted glass is produced by adding small amounts of metal oxides to the glass during its manufacturing process, resulting in various shades like bronze, grey, blue, and green. This type of glass reduces glare and solar heat gain while maintaining visibility.

Tinted glass is popular in residential and commercial applications because it enhances aesthetic appeal and improves energy efficiency. By absorbing a portion of solar energy, tinted glass helps maintain cooler indoor temperatures, which can reduce air conditioning costs​. [1]

12mm Warm Edge Spacer Bar (Black, Argon Filled – Silicone Edge Seal)

An argon-filled warm edge spacer bar enhances insulation, reducing heat transfer and edge condensation. This design maintains a stable indoor temperature, contributing to overall energy efficiency.

11.5mm Clear Laminated Heat Strengthened Inner Pane

The laminated, heat-strengthened inner pane adds safety and durability, improving structural integrity, sound insulation, and UV radiation reduction.

Sunsquare’s solar control glass options deliver exceptional performance by integrating advanced components, achieving a solar control performance G value of 0.346.

Our commitment to cutting-edge technology ensures superior quality and performance, making our skylights reliable for maintaining a comfortable indoor climate while reducing energy costs.

The Benefits of Solar Control Glass

Energy Efficiency

Solar control glass significantly reduces the cooling load on air conditioning systems by blocking substantial solar heat, lowering energy consumption and utility costs. This makes it a cost-effective and energy-efficient solution for temperature regulation. [2]

Comfort and UV Protection

Solar control glass enhances occupant comfort by minimising indoor heat gain and reducing glare. It maintains a comfortable indoor temperature by minimising temperature fluctuations caused by direct sunlight, allowing occupants to enjoy natural light without feeling overheated. [1]

Additionally, it filters out up to 99% of harmful UV rays, protecting skin and preventing the fading of interior furnishings such as furniture, flooring, and artwork.

Aesthetic and Functional Versatility

Solar control glass can be tailored in various tints and finishes to meet specific aesthetic desires and functional requirements. This versatility makes it ideal for both new construction and retrofit projects. [3]

Solar control glass also minimises glare, making indoor spaces more comfortable and reducing eye strain for occupants.

Environmental Impact

Solar control glass helps lower carbon emissions by optimising energy usage and decreasing the need for HVAC systems. This contribution to sustainable building practices supports environmental conservation and helps combat climate change by reducing structures’ overall carbon footprint. [4]

Increased Property Value

Buildings equipped with solar control glass are more attractive to prospective buyers or renters due to their enhanced energy efficiency and comfort. These features can increase property values, making investing in solar control glass a financially beneficial choice.

By incorporating solar control glass into building designs, one can blend energy efficiency, comfort, aesthetic appeal, and environmental responsibility, making it an excellent choice for residential and commercial applications. [3]

Summary

Solar control glass is a smart investment for enhancing building comfort and efficiency, particularly in the warmer months. As you prepare for spring and summer, consider the benefits of integrating solar control glass into your property upgrades. By incorporating solar control glass into building designs, one can blend energy efficiency, comfort, aesthetic appeal, and environmental responsibility, making it an excellent choice for residential and commercial applications.
