Thermally Efficient

Aluminium flush casement windows are an incredibly thermally efficient product. These windows have been manufactured and designed to reduce your energy consumption. The polyamide thermal break technology within the Alitherm 800 profile is a major selling point. This window reduces the amount of heat that escapes from the property, with the quality so high, it has been awarded the BFRC Window ‘A’ rating. The window also has U-values lower than 1.5w/m2k when properly utilised. Through your property being heated naturally, you’ll start to rely on your central heating less, saving you money on your energy bills and reducing your carbon footprint.

Highly Secure

Security is extremely important when it comes to windows and doors, which is why we offer our Lincolnshire customers the Alitherm 800 profile. This highly secure product combines a sturdy profile with complex locking mechanisms to provide optimum security for many years. This product has been tested to PAS 24:2012 standards, so your home will be secure from any uninvited visitors. The double glazing within the window itself provides an extra layer of security to your home, so you can sleep peacefully knowing that you and your family will be safe.

Stylish Visuals

The sleek framing of our aluminium flush casement windows makes them so desirable for Lincolnshire homeowners. The sash sits flush within the frame to deliver a stylish finish, without making the window look chunky, giving your home an enhanced visual appeal. All our casement window frames are available in a broad array of different configurations for your home, so you can build an aluminium window tailored to your tastes. The slim frames that we use from Smart allow more of the surface of the window to contain high-grade double glazing, improving your home’s overall aesthetics and making it brighter and more welcoming on the inside.

Little Maintenance Required

A bonus of using the Alitherm 800 profile is how incredibly adept it is at maintaining not only its structural integrity but it’s high-quality. This window is specially weather-proofed to give your Lincolnshire or Nottinghamshire home decades of service. All your windows will require from you in the occasional wipe down with a damp cloth to keep their ‘good as new’ look.


The damaging environmental effects that come as part of the ageing process of your windows are a thing of the past with our aluminium flush casement windows. With Class E 1050Pa water resistance and Class A5 2000Pa wind resistance, your product will not allow your home to be compromised by the harsh Lincolnshire winters, maintaining structural integrity and stylish design for many years.
