With the Origin Internal Door, you can even choose between horizontal and vertical Georgian-style bars, or choose both options for your door. You are also able to increase or decrease the number of glazing bars to suit your preferred aesthetic. For example – you may opt for more glass and less bars for a more minimalistic design. On the other hand, you may want to choose more glazing bars for an Art Deco look.

No matter the size and configuration options you choose – you can rest assured knowing you will be provided with a high-quality, reliable internal door.
