View Details +Sri Lanka’s architectural and construction sectors are undergoing a massive transformation. Driven by prestigious initiatives such as Colombo Port City and high-rise developments in Galle and Kandy, the island nation faces a critical challenge: extreme cooling requirements. Under a humid tropical climate, traditional building insulation materials often struggle to maintain performance, causing HVAC systems to run continuously. This results in skyrocketing energy bills due to recent tariff hikes in Sri Lanka's electricity grids.
Vacuum Insulated Glass (VIG) technology stands at the forefront of the solution. By creating a vacuum gap between glass panes, it completely eliminates convective and conductive heat transfer. This keeps interior spaces remarkably cool, making VIG an essential component for new-generation LEED-certified architecture in Sri Lanka. As green building regulations become mandatory across South Asia, local developers, contractors, and architectural firms are actively seeking reliable vacuum insulated glass manufacturers who can provide both standard configurations and tailor-made, large-scale shipments.
Traditional double glazing suffers from high failure rates in coastal tropical zones due to sealant degradation from UV exposure and high humidity, leading to internal condensation. Tempered Vacuum Insulated Glass bypasses this by utilizing high-durability inorganic seals. This ensures long-term operational integrity and maintains a U-value of less than 0.6 W/m²K, which outperforms conventional insulated glass units (IGU) by up to 300%. For coastal hotels, corporate offices, and transit hubs, this means significant operational cost savings and acoustic shielding from urban noise.

Understanding the core physical parameters of vacuum insulated technologies is essential when comparing insulation options. Below is an overview of the key advantages of fumed silica vacuum insulation panels (VIPs) and tempered vacuum insulated glass (VIG):
Get answers to the most common questions regarding vacuum insulated systems, procurement logistics, and installation.
In high-humidity coastal zones like Colombo, traditional double glazing units are prone to sealant breakdown over time, leading to condensation between the panes. Vacuum Insulated Glass (VIG) utilizes a high-durability inorganic sealing structure that completely prevents condensation. In addition, the vacuum gap eliminates convective and conductive heat transfer, reducing indoor heat buildup and HVAC energy consumption.
No. Because vacuum insulated glass is hermetically sealed under vacuum, it cannot be cut, drilled, or resized after fabrication. All dimensions, hinge placements, and cutout specifications must be carefully designed and finalized before starting production at the factory.
Under normal operating conditions, our fumed silica VIP panels are designed to maintain vacuum integrity for up to 10 to 15 years in cold chain applications, and even longer when embedded inside dry structural walls. Our advanced barrier films and getter systems help prevent gas permeation, ensuring long-term thermal performance.
Our products are shipped in customized, high-strength wooden crates designed for international sea freight. We use shock-absorbing layers, moisture barriers, and secure container strapping to prevent movement, ensuring the VIG panels arrive safely at Sri Lankan ports like Colombo.
Yes. The core material of our vacuum insulation panels consists of non-toxic, inorganic fumed silica. It is fireproof, non-combustible, and recyclable. Unlike polyurethane boards, our VIP panels do not release harmful VOCs during installation or use.
