Warm Edge Spacers
Our Thermobar and Thermoflex Warm Edge Spacers are engineered to reduce heat loss by up to 94% at window edges, enhancing thermal efficiency. These Passive House-certified components are designed for durability and compliance with global energy standards. Ideal for double, triple, and quadruple glazing, they ensure reduced condensation and lower energy bills for homeowners and commercial buildings.
Desiccants
We supply Eurosiv 3A desiccants, specifically formulated to adsorb moisture within insulated glass units. These high-purity desiccants prevent condensation and maintain long-term unit integrity. Compatible with all spacer systems, they are essential for meeting EN1279 standards and ensuring gas-filled units retain thermal performance over time.
Sealants
Our dual-seal systems include primary and secondary sealants like Euroseal PIB and Hot Melt, ensuring airtight and durable insulated glass units. These products provide structural integrity, gas retention, and compliance with European certification requirements. Suitable for manual or automated application, they support efficient manufacturing processes.
Decorative Glass Products
The DecraLed range includes adhesive lead, bevels, and colour films for creating stained-glass effects in sealed units. These decorative elements combine aesthetic appeal with thermal efficiency, offering cost-effective solutions for residential and commercial projects without compromising on performance.
Glass Machinery
We provide machinery for insulated glass production, including desiccant dispensers, gas fillers, and edge deletion systems. Our equipment supports EN1279 compliance and optimises manufacturing workflows, from spacer bending to unit sealing, ensuring precision and efficiency for small to large-scale operations.
