Halo System 10 FlushSash Casement Windows

With inward or outward opening options, the FlushSash has been designed to sit flush within its frame. This product mirrors the elegant window styles of the 19th Century, making it perfect for heritage and conservation projects. Though this window may look traditional, it offers deceptively modern performance. Equipped with energy efficient, five chamber PVCU cranes with double or triple glazing options, the FlushSash comes from the System 10 suite of profiles and offers all the strength, security and energy efficiency you would expect from a Halo product. The FlushSash also provides a cost-effective solution to a range of problems associated with historic homes. With the look of traditional stained or painted timber, it needs little or no maintenance and will appear virtually indistinguishable from the property's original windows. FlushSash is also a popular choice as an aluminium alternative especially for student accommodation.
