Outlining The Difference Between Flush Casements And Non-Flush Casements

In our product range, we stock flush casement windows (Envisage) and non-flush casement windows, which can cause confusion amongst some people.

They are two different window solutions and what makes them different is the ‘flush’.

A ‘flush’ casement window gets its name because it has window sashes that sit exactly flush with the window frame, making it totally flat.

Whereas, in a standard casement window (non-flush design), the window sashes narrowly overlap the window frame.

You will see what we mean if you come to our showroom and view both from side-on.

Here’s some additional info that you may find helpful.

When were the first flush and non-flush windows made?

It was in the 19th century that the flush casement window was developed and back then it was constructed with timber as wood was the main material used for window crafting. Most Edwardian, Victorian and late Georgian homes with their original windows have timber-built flush casements.

The non-flush casement window came a little earlier, in the 18th century, and would be made from iron by blacksmiths. 300 years on and non-flush casement windows are still the nation’s favourite window style.

Why are flush windows all the rage at present?

The present-day homeowner is on the lookout for windows with a different aesthetic to your average designs and flush windows fit the bill, that’s why Orion Windows decided to bring the Envisage range to the market.

Envisage is modelled on the styling of a traditional timber flush casement window and therefore has similar lines and proportions. We reject wood though and manufacture the product using UPVC to make it low-maintenance, secure and energy efficient.

Which window will suit my property?

We advocate choosing a flush casement window if your home is located in a conservation area or carries historical importance as planners will usually accept it as a replacement for old timber casements.

The flush finish that we spoke about earlier in the piece is also well-suited to modern properties and looks especially good in Black and Anthracite Grey.

A non-flush casement window is as popular as it is because of how versatile its design is. So, it can be installed in any property style and look fantastic.
