LandVac Optimum glazing is an industry-leading product in terms of performance and reliability. This vacuum insulated glass unit boasts a thermal insulation value of up to 0.4 W/m²K, which is significantly better than the industry average. With this level of insulation, buildings can greatly reduce their energy consumption, resulting in lower energy bills and reduced carbon footprint.
Furthermore, LandVac Optimum glazing is considerably less expensive than its competitors, making it an excellent choice for those seeking a high-performance product at a lower cost. In addition, it can be easily installed into standard profile frames, so installers and manufacturers do not need to redesign their profiles to accommodate it. This makes the transition to LandVac Optimum glazing seamless, while still providing the superior energy efficiency and insulation that this product is known for. Its reliability, coupled with its lower cost, make it an ideal choice for energy-efficient projects.
