uPVC Windows

Not every PVCu window system is the same

When you’re deciding which range of windows to choose for your home or commercial project, there are a number of factors to consider:

Will they look good?

Will they be sympathetic to the overall building design?

Will they exceed the most stringent energy efficiency targets and help minimise ongoing heating bills?

Will they provide the highest levels of safety and security?

Are they available in a wide range of styles and colour choices?

Is there a range of matching doors, roofs and other products available?

Will the products be guaranteed?

Master Plastics range is different to other systems on the market – being designed from scratch to take advantage of the very latest developments in window engineering technology. Combining high-tech design and engineering with the flexibility to create an individual appearance for every home, the our system pushes the boundaries of possibility with a range that doesn’t even need to look like PVCu. And with the patented double-action bubble gasket offering a continuous seal, even in the corners, draughty windows are a thing of the past.We manufacture a huge selection of uPVC windows at our factory in Bristol. Styles include Casement, Flush Sash, French, Tilt & Turn, Bow & Bay. Available in many colours with the choice of hardware. For the best prices call us on 0117 971 9922.

Gone are the days when PVCu windows were only available in white.

We offer coloured wood-grain foils which are fitted as soon as the plastic has been extruded in the factory, using the very latest in machine tooling – so you may find it difficult to believe the frames aren’t made of wood.

The brand new ‘flush sash’ window offers the aesthetics of a traditional pre-1932 timber window, with the sash fitting flush into the frame. Or if it’s a modern appearance you’re after, you could go for one of a shade of flat grey to achieve a contemporary look that delivers the highest thermal efficiency.

Available in sculptured (curved) or chamfered (flat) profile, the our ranges can be tailored to make sure you achieve exactly the look you’re aiming for - from a small single casement window to huge arched church windows.

Better for the environment

Energy efficiency explained

One of the most effective ways you can save energy within your home is through installing energy efficient windows and doors.

Whether double or triple glazed, our windows outperform most of the other leading windows in the UK – mainly due to our innovative uPVC multi-chambered and symmetrical profile design.

The BFRC Scheme is the UK’s national system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method of showing compliance for your windows installation. The rating scale runs from G right up to A+ and indicates how well a product will

• help you contain and conserve heat within your building in the winter

• keep out the wind

• resist condensation.

Our windows and doors can achieve an ‘A+’ rating*, which means you’ll be able to enjoy a warmer and quieter home as well as lower energy bills.


Our window profile is made from 100% lead-free PVCu – better for the environment and better for you and your family. You no longer have lead in your petrol or paint, so why choose to have frames containing lead?

Designed for today’s challenges

Whether you are aiming for a traditional look or a more contemporary style for your home, our range of windows has something to suit everyone’s tastes.

Available in a variety of styles and designs together with a wide selection of attractive colours ranging from standard white, cream and rosewood to grey, black, and Chartwell Green amongst others. 

Not only are our windows ‘A+’ rated for energy, they also meet the highest security standards and are manufactured in the UK – showing that our windows have plenty of substance as well as style.

Safe and secure

The window range offers complete flexibility, whatever the room or the size of opening you need.

Your home should be a safe haven – that’s why all our products are designed, tested and certified to meet the highest standards of security. We offer a range of different hardware on our windows, and you can rest assured that the design features built into our windows will offer the maximum security to your home.

Child restrictors can be fitted to almost any window to give you extra peace of mind that your little ones will be safe.

A police-backed initiative, Secured by Design status is awarded to products designed with exceptional security features as their main priority. Liniar products that hold this certification are tested to meet the requirements of the Association of Chief Police Officers.

The BBA (British Board of Agrement) is the UK’s major authority offering approval of construction products, systems and installers. The Liniar window system has been certified and approved, proving its quality to architects, engineers and specifiers in the UK.

Introducing the Master Plastics window range

Whatever the age or style of your home,there’s a window for you.

Casement Window

Casement windows offer total versatility and are still the most popular choice available today.

The traditional British window style offers slim sight lines to allow in maximum light.

You can say goodbye to draughty windows as the patented double-action bubble gasket, used in all our products, gives a continuous seal - even in the corners.

To add character you can add astrigal bars or Georgian bars.

Our range is available in a wide configuration of openings, colours, finishes, glass and hardware, which means you’ll be adding your own individual mark on your home’s appearance.

Tilt & Turn Window

If you love having your windows wide open to let in fresh air then why not consider Liniar tilt and turn windows for your ground floor?

The open-in style of window is very much a European design and is ideal for cleaning from within (in the turn position).

Ideal for high-rise as well as low-rise applications, the tilt and turn window offers a greater scope for larger opening lights than a traditional casement window and the larger panes of glass help its thermal performance.

Perfect as a fire escape or simply to let in more fresh air, most windows are supplied as ‘tilt before turn’ to make them safer and avoid the risk of children opening them fully in the first instance. 

With many practical benefits, tilt and turn windows are also available with as many options as our popular casement window.

Flush Sash Window

Want the look of a traditional timber window with all the advantages of PVCu?

Many property owners require a traditional timber window frame, sometimes due to planning or environmental restrictions. Timber frames tend to be expensive, need regular maintenance and can be difficult to replace.

Our flush sash window, like the rest of our EnergyPlus window range, is ‘A+’ rated, offering a lower cost window with higher thermal benefits than timber – in addition to being fully secure and available in a huge choice of colours.

Sash Horn Window

The sash horn windows provide the traditional style of yesteryear combined with 21st century materials, offering superior performance and functionality.

Sash horn windows preserve the classic look of wooden box-sash windows while maintaining the authenticity of any property.

They are designed to achieve the highest levels of weather-tightness and resistance to draughts.

Made to compliment our casement range, the sash horn window looks like a traditional sliding sash but performs as a casement - giving you the best of both worlds.

The high security shoot bolt locking systems provide unparalleled protection against break-ins and the windows can be customised with accessories such as Georgian bars for an individual appearance.

Bay and Bow Window

Bay or bow windows are a great way to bring more light into your home.

Choose from different styles and colours to get exactly what you need.

The innovative bay and bow windows offer a number of features and benefits unrivalled in today’s market place and are available in a range of styles.

The ultra-slim frames of our beautiful windows increase the flow of natural light as well as creating an enhanced field of view.

Enhance the look of your windows with a range of additional designs including leaded glass, Georgian or astragal bar, or decorative sash horns.

A world of colour

Not just available in standard white, the Liniar range can be personalised to suit the style of your home - as well as its colour scheme.

Child safety

Child restrictors can be fitted to almost any of our windows, for your peace of mind – ask for more details.

Hinge guards

Optional hinge guards add a further level of security to your windows, preventing the sash being forcibly opened from the outside.


We will be delighted to show you the wide range of handles that can be used on our products, so you can select the options to best match your interior.


We can also show you the wide range of glass and glazing options for your windows, to truly tailor them to your specifications.
