Sapphire Windows

Since 1989

The story of Sapphire Windows began in 1989 when our founder, Jeffrey Liew noticed the exceptional build quality of the windows in Europe while on a business trip abroad. He decided from that experience he would design his own home with windows that provide the same security, heat and sound insulation function.

With the sound famed reputation of Deceuninck, the world-leading uPVC maker, Jeffrey decided to source partners and supplies from them. This sparked the vision in him of bettering the lives of all the future homeowners. 

Today, Sapphire Windows is a leading window and door system specialist, renowned for its quality, workmanship and customer service. Driven by the company’s motto “Do it Right, Do it Proud”, we offer both innovative and timeless design solutions for all the homes around Singapore. 

The homes we touch show the world who we are and what is important to us. Our continuous development enables us to craft the best window and door systems through reverse engineering, research and development. To make your home safer, captivating and comfortable.
