OC-Ovolo & OC-Chamfered from Everglade

OC-Ovolo & OC-Chamfered

To give you more opportunities, One Collection is available in three styles, Ovolo, Chamfered and Flush.

With its smooth contours and stunning features, our OC-Ovolo series offers a traditional elegance. This range is ideal for period properties and homeowners who want to add or restore character to their homes.

OC-Chamfered windows feature sleek frames for a sharp, contemporary look. For design-conscious homeowners looking for a more modern finish, this is the perfect choice.

OC-Flush Sash

Our OC-Flush windows and doors are a great upsell for both timber and uPVC window replacements. They’re designed to replicate the appearance of timber, combining the authentic beauty of traditional timber with the modern benefits of uPVC. The One Collection flush window and door makes a stunning addition to both traditional and contemporary properties, transforming period homes, country cottages and modern townhouses. They’re also ideal choices for properties in conservation areas, as the traditional finish is in keeping with period properties.
