How to choose the suitable IGU glass unit for your project?
Selecting the right Insulated Glass Unit (IGU) for your project can feel like a daunting task, but don’t worry – we’re here to help guide you through the process! 🤗
Assess Your Needs
- The first step is to clearly define what you need from your IGUs. Are you looking to improve the thermal insulation of your project? Or perhaps you’re more concerned with soundproofing or safety performance?
Consider Energy Efficiency
- Energy-efficient insulated glass units can help reduce heating and cooling costs, making them an excellent choice for those looking to save on energy bills. Look for units with low U-values, which indicate a high level of insulation.
SHGC – Solar Heat Gain Coefficient
- The SHGC measures the amount of solar heat an IGU glass unit allows through. If you’re in a hot climate, consider a unit with a lower SHGC to minimize heat gain. Conversely, if you’re in a colder region, a higher SHGC can provide passive solar heating.
VLT – Visible Light Transmission
- VLT refers to the amount of visible light that passes through an IGU. If you want plenty of natural light in your space, opt for a unit with a high VLT.
About Sound Insulation
- For projects in noisy areas, consider an IGU with superior soundproofing capabilities. A high Sound Transmission Class (STC) rating indicates better sound insulation.
Safety Performance
- Depending on your project, you might require Insulated glass units with additional safety features. Laminated or toughened glass can offer enhanced security against break-ins and accidental breakage.
In addition, don’t forget durability: Look for IGUs that are designed to withstand the test of time. Units with durable coatings can resist scratches and require less frequent cleaning. And also check whether the IGU glass unit can be customized to suit your specific needs. This could include options like tinted glass, patterned glass, or decorative add-ons.
