1. Highly durable PVCu

Constructed with 3-chambers, the profile allows separate drainage and reinforcement. All frames measure 70mm from front to back allowing the replacement of traditional 3" timber frames with the minimum of 'making good' remedial work. The PVCu system is also bevelled to provide a slimmer, more attractive look.
Manufactured to BS 7413, the British Standards for PVCu window extrusions, the profile carries a full 10-year guarantee against discolouration and degradation.
2. Internal beading
Unlike many windows, Rehau 70mm is internally beaded. This means that the beading that secures the glass into place is located on the inside of the frame & can't be removed from the outside - helping to make Rehau 70mm one of the most secure systems on the market.
3. Fully welded frame

Many window frames are manufactured with the PVCu lengths mechanically joined. This 'nuts and bolts' method can often lead to the frame being less strong. Water can find its way into joints and extreme temperatures can cause points of weakness.
With Rehau 70mm, all joints are welded. This means that the window is a homogeneous structure, providing integral strength to the frame.
4. Central deadbolt

The steel central deadbolt acts in the same way as a door lock - shutting out potential attack from a jemmy or crowbar at the centre of the window.
Positioned in a slim, durable gearbox, the deadbolt completes the locking mechanism that means that the Rehau 70mm window meets the standards set by BS 7950 - the British Standard that relates to a window's protection against forced entry.
5. Shootbolt locks

The solid, bi-directional locking bolts anchor the opener securely into the top and bottom of the frame to ensure that the vent receives all-round protection.
The shootbolt is manufactured from high quality steel, protected with a galvanised zinc coating and chromatised for additional protection and maximum operational life.
6. Espagnolette rollers

The 2 adjustable rollercams operate by pulling the opener and providing compression to ensure a secure and effective weatherseal all around the window.
7. One-piece keeps

The one-piece corner keeps provide excellent location for the rollercam
and shootbolt, securing the opener to the outer frame. They also come with a
'night-vent' position as standard, ensuring ventilation whilst the window is locked.
