Vertical Sliding Windows

Traditional windows without compromise

Designed to provide all the benefits that can be derived from high performance, modern materials, the vertical slider provides a long term, cost effective solution for period style properties. Advanced technology works in harmony with traditional design, to provide extra comfort and practical features for modern living, without any compromise to character or appearance.

The PVC-U window frames are designed to provide optimum strength, superior thermal properties and excellent weathering performance and will retain their pristine appearance year after year with the minimum of maintenance. The vertical slider has been designed to be suitable for commercial and domestic buildings, in both replacement and new build markets.

Traditional appearance with durability

Profiles are manufactured to the highest standards, from a formulation which includes a high impact modifier to withstand cold weather and a UV light resistant pigment to maintain colour and appearance for years to come. It is this formulation which prevents the PVC profile from degrading, bending or warping.

Structural strength is enhanced through the use of steel and aluminium reinforcement through the internal chambers of the profile.

Years of engineering experience mean that you have total confidence in the durability and longevity of the window frames, without having to cover the cost of high maintenance or spoiling the appearance of the property.

Traditional style with benefits

Much thought has gone into the design to ensure that the attractive style of the vertical slider is retained, whilst providing all the benefits that modern technology can provide.

For ease and cost effective fabrication, each sash option is post co-extruded. Thermal properties are enhanced through the use of 24mm glazing as standard. Excellent weathering performance is increased with a Pile seal detail on the sash edges and outer frame and air flow specification can be achieved through the use of trickle or glazed in vents to suit particular applications as required.

Traditional craftsmanship using modern technology

A wide variety of decorative options and colour choices are available, designed to the finest detail for a perfect finish. Tilting sashes are a major feature, allowing ease of cleaning. Tilt restrictors ensure the tilt mechanism works smoothly and safely. The vertical slider provides a blend of advanced technology with the craftsmanship of old. It is a simple solution in long term, cost effective, window maintenance, with all the benefits and comfort of modern living, whilst retaining the charm and appearance of a past era.

Character with assurance

You can rest assured that your Allerton Glass and Glazing window comes with the highest quality assurance, with all materials manufactured under the strictest quality controls. Safety and security are of prime importance and every detail has been considered to ensure that all hardware and locking options exceed requirements.

Character with ease

Choosing a PVC-U window will mean the end of costly, time consuming painting every two to three years. A damp, soft cloth is all it takes to clean a PVC-U frame. The vertical slider is even easier, with the use of the pivot bar. This allows the window to tilt, so that the exterior glass can actually be cleaned from the inside. Maintenance simply couldn't be easier.

Character with choice

An attractive ovolo shaped bead comes together with a choice of 2 cill sizes (150mm & 210mm), 3 sash options to allow a variation of application styles, including an equal sightline option for the top and bottom sashes, plus a deep bottom rail for a truly traditional appearance. In addition, you can choose a Georgian bar option to add a decorative horn. And for those who prefer a true timber appearance, the vertical slider is available in a mahogany, rosewood or light oak finish. You can even choose a timber appearance on the external face, with a white finish on the internal to maintain a light airy appearance to the inside of the room. White and cream woodgrain finishes are also available. To create the perfect finish, white, brass or chrome hardware options are available as well as end caps for both the cill and the sash stop.

Character with comfort

Choosing a vertical slider fitted by Allerton Glass & Glazing will give you all the benefits of a modern window with all the charm and character of a traditional vertical sliding window. Excellent thermal properties and weathering performance will conserve heat and save on heating costs. Combine these benefits with the charm and character of a traditional vertical slider and you have the best of both worlds.
