How Cortizo sliding patio doors differ

Within the Cortizo sliding patio doors range are two well-known products, the Cortizo Cor-Vision (also available as a Cor-Vision plus model) and the 4700.

The construction of these two doors is different as is the price. The more expensive is the Cor-Vision slider because this comes with a structurally bonded construction and is made around the glass as a result. The manufacturing is also more complex.

Therefore, the 4700 model is available unglazed, with the Cor-Vision model only available glazed.

Available at a more affordable price to the trade, builders and homeowners direct is the 4700 model. This features a conventional dry-glazed design, made in the factory unglazed, with the glass fitted on site.

One of the key considerations when choosing sliding patio doors is the sightline at the mullion or interlock. The Cortizo 4700 slider comes with a slim 47mm interlock. The Cor-Vision is even slimmer

There are some design differences between these two sliding door models as well as some similarities.

The 4700 model suits more standard installations and is especially cost-effective as a replacement for dated doors with a more modern alternative. Cor-Vision can also work in replacement applications. However, it’s especially suitable for new build extensions, where the frame can be set into the structure reducing the sightlines even further for a truly minimalist and ultra-slim sliding door model.

Both doors come with a standard or flush track option, an open corner design and even a pocket sliding door option.

Looking for steel-look sliding doors? Then the Cor-Vision with its slimmer all-around styling suits industrial and heritage style doors better. Both door types come in the full range of RAL colours, giving you over 150 to choose from.

Even better, both of these Cortizo sliding patio doors work well inside the home. You can use them as a stylish room divider or separate a conservatory from the main room.
