We offer a full range of windows, from casement windows to sliding sash windows. We’re also able to offer Timber and Aluminium windows.
Modern aluminium windows have many benefits, from strength, security and slim sight lines to resistance to the worst of the British weather.
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.
Whether you’re looking to replace your front door or are thinking about having a new Bi-folding door fitted to improve your home, we can help.
Our composite doors are exceptionally secure, energy efficient and designed to stay looking good on the inside and out, year in and year out.
Our bi-folding doors come in an array of finishes and colours, including woodgrain effect, with a slim sightline and superb levels of security.
A conservatory is a superb way of opening up your home to drench it in natural light, break down the barriers between your inside and outside environments and give your property more living space for whatever you need it for – all without the additional hassle and expense of moving.
At Isis Windows, we offer extremely long-lasting conservatories, orangeries and sunrooms to suit your home, in a wide variety of styles, such as Victorian and Edwardian, to give your property more than a hint of class and distinction. And if you want something unique, talk to us about our bespoke conservatory service. We use PVC windows for the strength of this material and its low maintenance qualities, as well as for its cost-effectiveness and smart appearance. And we use Ultraframe roofing systems to create whatever conservatory you have in mind to enhance the enjoyment of your home.
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.
