Other Options

We bring increased flexibility to design, with a wide choice of low maintenance PVC-U colour finishes. With colour driving the replacement sector and an increasingly important feature in new build, we offer a wide choice of foils and a state-of-the art spray painting capability.

We’ve not quite got all the colours of the rainbow, but we’ve got more than enough beautiful shades, wood effects and textures to satisfy. If you want something that’s not shown in our swatch book, we can probably do that too – just ask. You can even choose a different colour and finish for indoors and out. Whether you want to stand out or blend in, we’ll do all we can to match your dreams and and the perfect finish for your site and your home.

You might spend more time looking through it than at it, but glass is worth a closer look. New technologies have produced practically invisible coatings that can actually help to keep your home warmer. Sealed units are filled with inert gases and warm-edge spacers form a thermal barrier between the warmth indoors and the chill on the outside. Pick the right glass and your home can be much more comfortable.

A perfect finish means that every component of your windows and doors has to work together and that includes things like hinges, handles, letter-plates and door knockers. It’s not just function – although it goes without saying that that’s essential – appearance matters too. Complementing a door or window
with the right hardware transforms it.


If your home is modern, you’ll want to reflect that in simple hardware with great lines. If it’s traditional, perhaps you’ll want more detail. Either way, you’ll want hardware that’s built to last with robust materials and quality
finishes. You’ll want locks and handles that are easy to use, and which suit your lifestyle. And you’ll want colours that work with your frame or door shades, either setting up a bold contrast or blending gently into a sophisticated and stylish whole.
