Trusted Slim Glazing Experts in Banbridge
IMC Glass has been manufacturing specialist glazing solutions for over 30 years, establishing itself as Ireland's only certified manufacturer of Slim Glaze double-glazed units. Our commitment to quality is demonstrated through rigorous product testing and accreditations including BSEN1279 certification, British Kitemark licensing, and CE marking. We pioneered heritage-focused glazing technology that combines narrow sightlines (as slim as 7mm) with thermal efficiency, achieving U-values as low as 0.9. Our technical expertise extends to gas-filled units using Xenon and Krypton for superior insulation, warm-edge spacer technology, and compliance with strict moisture penetration and gas leakage standards.

With installations in iconic structures like Ashford Castle and Dublin Castle, we combine architectural preservation with modern energy efficiency. Our products undergo bi-annual testing by the British Standards Institution, ensuring ongoing compliance with European regulations. We maintain full traceability through certified gas-fill labels on every unit, providing customers with verifiable quality assurance. Our team's experience spans heritage restoration projects across Ireland, the UK, and Germany, serving both listed buildings and contemporary developments.
