So by specifying Cristallo uPVC System 1, you can deal with one company for the whole window system, including PVC-U profiles as well as hardware.

UPVc Case Studies

Traditional UPVc

Our team has extensive construction industry experience, from engineering skills to actually fitting windows for a living. Working together to design our window and door systems they have designed out niggling problems and designed in efficiencies that make our frames work better for longer.

Cristallo uPVC System 1 is a comprehensive PVC-U window and door system comprising the following four main product ranges:

  • A fully chamfered 60mm system
  • A fully integrated 70mm system utilising 60mm sashes
  • A decorative fully sculptured 70mm system
  • 100% recycled 70mm profile system

These high-performance systems have been carefully designed to meet the requirements of regional Building Regulations throughout the UK, including variations for Wales, Scotland, Northern Ireland and for the Republic of Ireland.

The fully chamfered 60mm system and the fully integrated 70mm system are available either internally or externally-beaded with a range of chamfered or sculptured sashes.

The decorative fully sculptured 70mm system is available internally-beaded with dedicated feature beads.

The Cristallo uPVC System 1 has been designed on the basis of full integration, utilising common parts, giving the window manufacturer the benefit of less stock and more market flexibility.

Sash Horns

Enhance your window by choosing either run-through or plant-on sash horns. The run-through utilises mechanical joints rather than welded to allow the horn to be a continuous part of the sash giving the window a more authentic overall look. The plant-on is a sculptured moulding that is fixed to the underside of the top sash.

Mechanical Joints

The fully mechanical joints take authenticity to another level because the 45 degree PVCu welds on the frame and sash are replaced with 90 degree mechanical joints as found on traditional  timber windows.

Seamless Welds

This revolutionary process disguises the external 45-degree corner welds with a flush mitre providing a far superior aesthetic finish. Available on woodgrain windows only and a mininimum window size of 475mm wide x 900mm high.

Period Style

The  Legacy PVCu sliding sash windows carry all the beauty of a traditional design, combined with modern industry thinking that not only enhance the ease of fabrication and installation but also the day-to-day use.

From near-invisible joints, the elegance of the run-through sash horn to the curvy ovolo frame shape, these are just a handful of the many clever details that work together to create the most graceful and advanced sliding sash window on the market.

With the rise of PVCu sliding sash windows being specified in premium developments, as homeowners recognise not only the elegance of this traditional style- but also its superior weather performance.

Three new colours have been introduced, providing additional choice.

Also, our stunning hardware range has become an art form, underpinned by underlying strength and security.

The Finer Details

Our PVCu sliding sash windows hold a host of impressive features that not only add to its good looks, but also enhance the performance of the window.

All parts of the stunning system has the crucial ovolo shape adding traditional character like no other.

Planning and Conservation

We’re often faced with projects that require special features to fit in with the unique character of a conservation area.

In the past, many planners used to refuse applications to replace timber sashes with a PVCu alternative.

However, the  Legacy sash window has been designed to recreate tradition, which has led to an increasing number of approvals granted.

Exceptional Thermal Efficiency

 With fuel prices constantly on the rise, thermal performance is crucial. The window frames are built to last and to resist the ever-changing conditions the British weather throws at them without losing their immaculate appearance. An innovative dedicated weather bar adds another level of defense against rainwater; a feature unique to this type of window.

A’ Energy Rating Available

The frames and sashes are multichambered, using the power of air as an insulator to stop warmth escaping.

Our sash windows are available with 24mm argon gas filled double glazed units enabling them to achieve an outstanding energy rating of ‘A’.

The efficient air filled sash window unit achieves an energy rating of  ‘B’ as standard and a u-value of 1.6/Wm2K.

Colourmatching Woolpile

The sash windows feature woolpile strips that provide an excellent seal against weather, air and debris infiltration.

We’ve paid attention to every detail and as something new we’ve introduced colourmatching woolpile to ensure that every single window is perfectly finished.


PVCu can be recycled over and over again, without any deterioration in performance. PVCu is an environmentally friendly choice as most PVCu windows will be recycled.

By choosing our sliding sash windows you can keep your home warm all year round, reduce your heating bills as well as helping the environment.


Peace of Mind

Our sash windows deliver the most advanced levels of security without adding complex operation. They are practical and come with all the safety features you would expect from a modern window solution. The window is secured using a snail cam fitted to the top face of the bottom sash. By turning the lever you release the cam from its keep. You have the option of choosing a key-locking or non-locking system.
