Stable Doors

Our PVCu Stable doors offer more versatility than a standard door, allowing maximum ventilation while retaining high security for children and pets. Because of its unique high-security multi-locking system to both top and bottom sections, our stable door is considered to be more secure than many conventional PVCu double glazed entrance doors.

Ultion High-Security Euro Cylinder

ultion door locks

At Test Valley windows we do not use standard euro cylinders that can be bumped, picked, and snapped. Millions of doors in the UK can be opened quietly in under 10 seconds with normal tools. Even the most secure multi point hook mechanisms are disabled when the cylinder lock is snapped. Securing your doors with Ultion defends your home from this and all other known Euro cylinder attack methods.

Fullex Multipoint Door Lock

Our Fullex XL door locks are Secured by Design and exceed the highest industry security standards. When you close a door fitted with Fullex locks, you lock out unwanted visitors and protect your home from the elements.

The operation of the lock is simple and once locked, you are protected by up to seven steel locking points, and smooth operation is assured by rolling steel compression cams. You can rely on the XL range for your long term piece of mind. The XL lock has been tested to over 50,000 operations, which equates to 20 years of use.

Superior Weather Seals

Our Q-lon weather seal is said to be the Worlds best door and window seal. It considerably out performs both EPDM and TPE rubber alternatives. As well as out performing the competition on air tightness Q-lon has the best acoustic and thermal performance across the widest temperature range. The 99% shape recovery of Q-lon ensures that your windows and doors will retain the highest weather performance for decades to come. The seal’s low sightlines leave your doors and windows with a sharp finish, clean lines and no unsightly black gasket protruding from the frame.

AV2 Slam Lock

Choose our new Slam lock, and there is no need to lift the handle up to engage the lock. The hooks engage the moment you close the door, then just turn the key to lock fully. With the fixed outside handle option as soon as the door is closed no one can walk in without a key. A demonstration door with this lock is in our showroom.

Security Glass

All door glass designs are installed with toughened safety glass as standard. This glass is over four times stronger than float glass, and if it breaks, it does so in a safe manner.

Test Valley windows strive to offer all our customers the ultimate choice and service. With this in mind, we offer our unique security guarantee. To qualify for this guarantee all doors and windows purchased must be upgraded to have our sealed units fitted with laminated glass to either the inner or outer pane. Please note that this option is not available on all glass designs.


Door furniture is available in 5 finishes. Chrome, gold, white, black and satin silver. The lever/lever and lever/pad handles incorporate a spring cassette to eliminate any dropping and has been tested to 50,000 cycles.

Letter plates are also available in 5 finishes. There are two options, our standard and deluxe. Our deluxe option opened to 180 degrees and was cycle tested to 100,000 operations. The external flap houses a peripheral seal that also forms a full thermal and acoustic barrier.

Our urn knocker is face fixed to remove the need for fixings on the inside of the door.
