Evolution Flush 70 Window

Evolution Flush 70

Timber alternative windows details

The timber alternative flush 70 window profile has all the characteristics you’d expect from an Evolution window – except the frame is only 70mm deep.

It has all the features of 82mm profile, including unrivalled energy efficiency, exceptional weather proofing and low maintenance without compromising on quality and design.

Whether you choose double or triple glazing, our windows are all argon-filled as opposed to the less efficient air-filled units. This applies to glazed units with Georgian bars and to leaded units too. Argon is a noble glass which means it doesn’t react to anything as much as normal air does. This means that heat is not lost as easily through the unit. If you use air-filled glazed units, the heat can escape through the unit much more easily. This of course contributes to the overall energy rating of the window.

Multipoint shoot bolt locking

When you lock the window shut, not only do bolts lock into their keeps next to the handle, but shootbolts at the top and bottom of the window lock into their keeps too meaning your timber alternative window is as secure as any other modern window on the market.

Lockable night vent facility

The window locks in a slightly open position, allowing ventilation into the property without compromising on security by leaving a window wide open inviting potential burglars in.

Outer frame

The timber alternative flush 70 profile benefits from exceptional performance without the bulk of a large frame. Take advantage of the thin profile and flood your home with natural light.

The minimalist design of the window offers all the benefits of a high-performance Evolution window. With a quality wood-effect, these elegantly crafted windows fit flush into the frame with sleek lines and simplistic but effective detailing. The flush 70 does not come with working peg stays but has friction hinges instead.
