A bay window is a window space projecting outward from the main walls of a building and forming a bay in a room, either square or polygonal in plan. The angles most commonly used on the inside corners of the bay are 90, 135 and 150 degrees. Bay windows are often associated with Victorian architecture. They first achieved widespread popularity in the 1870s. The windows are commonly used to provide the illusion of a larger room. They are used to increase the flow of natural light into a building as well as provide views of the outside that would be unavailable with an ordinary window.

Ideal for installations where the house facade demands the appearance of a wood window but the intenral decor suits a clean white finish. Beautifully detailed, the outside looks just like realwood to add an extra depth and dimension. The deep, woodgrain finish itself has been developed so that it adheres to the PVCU section for year, after year, after year without degradation, maintaining its appearance and beauty. We carry out exhaustive tests to ensure its strength and adhesion properties. This involves using weights to test the integrity of the material and the adhesive, so you can be sure of a first class product every time. There are five choices in the Woodgrain Collection including Dual Golden Oak.
