Duratech APX M4A B700 780x980 White uPVC Centre Pivot Roof Window

Whether you’re looking for a stylish window option for your loft conversion or want to increase the amount of natural light in your home, you can’t go wrong with a Duratech APX B700 White uPVC Centre Pivot Roof Window. 

Suitable for roof pitches between 15 and 90 degrees, this window is a perfect option for almost any home. Combining style with technical performance, you will find that the Duratech APX B700 White uPVC Centre Pivot window sits snugly against your roof line which maximises its insulating properties.

The window has been manufactured with a centre pivot, providing you with two opening position locking options. The two locking options allow greater control over the volume of air flow that filters through the room making this particular window perfect for all seasons.

As well as providing an increase of air flow in the warmer months, the design of the Duratech APX White uPVC Centre Pivot Roof Window has been optimised to provide maximum insulation. The aluminium reinforced PVC profile provides resistance against humidity and condensation ensuring that your home remains free from the effects of damp.

A high thermal performance rating is incredibly important when thinking about roof windows. Heat rises and will therefore escape through the window if the right insulating properties haven’t been installed. If you choose a Duratech window, the insulating properties could improve the energy rating of your home which will in turn have a positive effect on your energy bills.

It is also important to note how the stylistic features of the design enable the window to flood your home with more natural light. The slim and stylish frames let in 10% more light when compared to other designs on the market while the white finish reflects light back into the room, rather than absorbing it, making for a much brighter appearance.

Thermal Insulation

With the standard pane having a U value of 1.1 W / m2k and the 24mm double glazing filled with argon gas, you can be sure that all of our Duratech windows guarantee fantastic thermal insulation.  The technology reduces heat loss in the winter and limits overheating in the summer.


All of our Duratech Windows are fitted with handles which are manufactured from moulded zinc. The intelligent design enables three locking positions – one closed and two opening.

Quality Manufacturing

The Duratech range is manufactured in an ISO 9001, ISO 14001 and OHSAS 18001 certified facility which is your assurance that quality control is paramount. Using the latest technologies, we ensure that the best industrial, environmental and labour standards are achieved each and every time.

All of the Duratech windows are tested by an independent testing company which means you can expect the highest standards when it comes to energy performance and water tightness.


The installation methods have been tried and tested and are well known to experienced window fitters. Easy to install, we also supply step-by-step instructions if you are looking to fit your windows yourself.
