Flush Casement Windows

Genesis Flush Sash Casement

The new Genesis Flush traditional casement window combines the beauty and elegance of traditional windows with all the benefits of modern materials, namely maintenance-free security and thermal efficiency. It makes a stunning addition to both traditional and contemporary buildings, transforming period homes, country cottages and modern townhouse amongst others. Its unrivalled aesthetic appeal makes it one of the most attractive casement windows on the market today.

  • Seamless GRAF Weld
    Since investing in a Graf weld machine in 2016 demand for the superior corner finish it produces has been growing ever since.
    Consumers love the sleek beautiful finish offered especially and when compared with a ‘standard weld’ the finish is quite oustanding.
    Unlike a standard weld the excess sprue is pushed inside the weld rather than being allowed spill from the join requiring it to be ‘knifed off’
    The end result is an almost invisible joint which enhances the flush window aesthetics and raises the bar.

    Fully Mechanical Construction
    For those looking for the most authentic looking timber alternative flush window, we launched the fully mechanically jointed version.
    Properties in conservation areas or customers with a particular desire for the window to look as close as possible to timber will likely choose teh fully mechanical option. Each section of the profile is milled and assembled by hand with care and attention to detail ensuring the end result looks just like it’s timber counterpart.

    With homeowners becoming more security conscious and new-builders having building compliancy to meet it’s vital that our products can address their requirements. The flush sash is offered with PAS24 security for added peace of mind of you and your customers.

    • PAS24 accredited
    • Class A4: 600Pa Air Permeability
    • Class 7A: 300Pa Water Tightness
    • Class A5: 2000Pa Wind Resistance

    The beautiful thing about the Genesis flush window, apart from it’s looks, is that fact that there is little or no maintenance. All that is required is a wipe down with lightly soapy water from time to time to keep it in perfect condition.

    As with all the products in the Genesis Collection the Flush casement is available with a wide variety of glass options depending on the homeowners requirements. These include :-

    • Obscure Glazing
    • Toughened Safety Glass
    • Laminated Glass
    • Acoustic Performance Glass
    • Energy performance Glass

    Ventilation is an important consideration for most homeowners and dependent upon their needs there are two features available.
    Firstly included as standard is the ‘night vent’ facility which allows the window to be locked off in a slightly open position.
    On newbuilds, unless a mechanical ventilation system is being fitted, trickle vents will be required and these are fitted to the head of each frame above the sashes.

    As part of the bespoke nature of everything we make you will have the choice of style and colour of hardware.
    Handle types include contemporary, teardrop and monkey tail. Dummy peg stays are available for the teardrop and monkey tail variants.
    Colours include chrome, black, smokey chrome, graphite, gold, satin and white.

    To complete the authentic appearance the windows can be decorated exactly as required with either full astragal bar detailing, internal Georgian bar or leading.
    Each of these feature is expertly applied to give a finish that looks both beautiful and well crafted.

    The beauty of the Genesis flush casement is in it’s versatility.
    It’s perfect for traditional homes, contemporary properties, period homes, country cottages and modern townhouses amongst many others.
    Its unrivalled aesthetic appeal makes it one of the most attractive flush casement windows on the market today.
