It is important that the style of your new windows and doors matches your home. Whether you are changing the original windows or replacements installed at a later date, you should always consider the internal as well as external appearance, as you will spend more time looking out of your new windows than looking in! Also, give thought to the practicalities of whether you want your sashes to be inward or outward opening, left or right hand opening, or for access and egress.

Rationel offers a wide range of window options. So consider the requirements of your house carefully, and we will find the perfect solution for you and your home.

We have bespoke windows and doors designed for almost any building or architectural style.
