We offer a full range of windows, from casement windows to sliding sash windows and uPVC options.
Our uPVC windows are available in a stylish range of styles and colours, including trendy pastel colours such as Cherwell Green.
Sash windows, or those which slide open vertically, are elegant with subtle proportions and have been a popular choice since the 18th and 19th centuries.
Our uPVC timber windows are becoming increasingly popular, offering the beauty of timber with the energy-efficiency and hardiness of uPVC.
Isis is a name with a long, proud history. Its first recorded use is as Isa in 1350, while the first evidence of its modern form dates from 1577.
It was also the name of an Ancient Egyptian goddess, later worshipped by Greeks and Romans, but, in Oxford, Isis has long referred to the stretch of Thames north of Iffley Lock.
It comes from the old name for the River Thames, Tamesis, which in the Middle Ages was wrongly taken to be a combination of Thame and Isis.
Isis has long been associated with Oxford rowing. Its the name of the famous university’s reserve boat for its rowing crew, and of a student magazine first set up in 1892.
The university’s research and technology company is also called Isis, as are several other businesses and organisations keen to highlight their connections with Oxford.
We love Oxford and Oxfordshire, too, and are delighted to have our pride in our city reflected in our name.
FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. Every FENSA Approved Installer, from large national brands to small local companies, is assessed regularly by us to ensure its standards are continually maintained.
