The Stellar Flush aluminium window and door system is designed for both high performance and simple fuss-free installation. It’s quick to glaze and with the unique reverse butt joint option eliminates the need for dummy sashes or adaptors so you can maintain internal glazing with more affordable designs. Strong aluminium sections allow for large glazed areas, while advanced thermal break technology ensures no compromise on insulation.
Stellar Flush aluminium windows deliver sightlines 30% slimmer than competing systems, giving you 12% more glass area for superior natural light and cleaner aesthetics. With A+ energy ratings and a design that works equally well in Georgian townhouses or modern new-builds, Stellar combines thermal efficiency with authentic flush styling.
The system requires minimal maintenance and uses sustainable aluminium throughout, backed by comprehensive guarantees for long-term peace of mind.
Standard Flush Sash
Flush on the exterior with a subtle stepped profile internally. This design provides excellent weather performance while maintaining the authentic flush appearance from outside.
Fully Flush Sash
Completely flush inside and out for a seamless, contemporary finish. Perfect for modern interiors where clean lines are a priority.
Both options deliver identical thermal performance and security—the choice depends purely on your aesthetic preference and interior design.
Consistent glass alignment – Casement and fixed lights sit flush for a uniform appearance
Opening casements and fixed panes align perfectly, creating a uniform grid-like appearance. Particularly important in bay windows and multi-pane installations.
Patent-pending reverse butt joint – Eliminates the need for dummy sashes or adaptor profiles
This innovative corner joint delivers true flush aesthetics without additional dummy sashes, resulting in cleaner appearance and reduced costs.
Easy-clean rebates – Simple to maintain and keep spotless
Water and debris drain away easily with no corners that trap dirt. A quick wipe with soapy water keeps windows pristine.
Enhanced thermal gaskets – Tailed gasket design improves insulation and reduces heat loss
Superior sealing between glass and frame prevents cold air infiltration, contributing to A+ energy ratings and lower heating bills.
