About Us

Lumi is a range of award winning contemporary styled windows and doors which features a unique exterior all-glass appearance with superior thermal properties. We are based in Co Antrim Northern Ireland and the complete Lumi range is manufactured in our recently extended Ballymena factory site. Lumi windows are complemented by a range of sliding doors, patio doors and composite doors, all exclusively designed to match the all-glass external glazing effect and featuring the highest levels of security and thermal efficiency. Lumi is the brain child of MD Asa McGillian, who wanted to design a window system which looked completely different to anything else on the marketplace. The window frames are fibreglass (GRP) which we have been using for years in our composite doors. GRP is a strong robust material which can hold the weight of our triple glazed units on larger panes. Currently we do not have an on site showroom and visits to the factory are by appointment only.
