Transform your space

Tired of dull, cluttered spaces that feel disconnected from the outside world?

Cortizo 4700 sliding 3 sash doors create a seamless connection with nature, flooding your space with natural light and creating a calming sense of openness.

Their minimal design and modern style will transform any room, while the slim central interlock and streamlined frame emphasise the sleek aesthetic.

If 2 sash isn’t the right size for you, we stock a range of Cortizo 4700 sliding door sizes, including:

Increase natural light

A lack of natural light saps the life out of even the most beautiful spaces.

Cortizo sliding doors will maximise daylight, creating brighter and more inviting rooms.

Natural light has several benefits for your health and wellbeing, and will make every moment at home feel special.

Fitting & Measurements

The key measurement to focus on is the exact size of your structural opening. 

For the best fit, the opening should be 5mm larger on all sides than the sliding door size you are ordering. 

For example, if you order a door that’s 2100mm(h) by 4000mm(w), your structural opening should be 2110mm (h) by 4010mm (w)  to ensure a smooth fit.

This slight difference allows the doors to be installed smoothly and securely.

Please be aware that we do not supply fully flush-fitting doors (flush on both sides) as they do not provide a weather rating. The final finish is up to the builder, but in most cases, the interior side will be built up flush. However, the exterior must allow for proper water drainage. While the builder may install a flush drainage system, there must always be a slight step from the outside to the inside.

We advise each project has its own specifications. If this is a new build, then laminate glass is required to comply with document “L”. There may also be a requirement for trickle vents to be incorporated into your project. We advise checking this before purchase as all orders are made to order and sizes/specifications cannot be changed once manufacturing commences. Please note orders for triple glazed glass are not available on the website, please contact us if you require triple glazed glass.
