Which materials are best for internal bifold doors?
Internal bifold doors have a different set of requirements to external bifold doors. For example, thermal efficiency is incredibly important for external doors to protect your home from the elements. This means they are usually fitted with double or triple glazing, which increases door depth.
Deeper doors take up more space when they are stacked, which can be a problem in smaller rooms where space is an issue. For internal bifold doors, double glazing is not necessary and can be seen as superfluous with increased costs (and loss of space).
Many uPVC and aluminium doors that are stated to be ‘internal’ are actually designed to be external doors. They contain a number of unnecessary requirements, which increases their price. This means you will pay for additional features that are not needed.
Vufold’s internal wooden bifold doors are specifically designed to be fitted internally. They can easily be fitted flush (at the same level as the floor) and do not contain unnecessary utilities such as door hardware or double glazing. Internal bifold doors have slimmer frames than external bifold doors to make sure they can be used easily as an internal door. Instead, they utilise new technology and designs to save space and create a modern look for your home.
Maintenance required for each material
Maintenance includes things like painting, repairing or replacing doors. Internal folding doors require much less maintenance than external doors, as they do not have to face intense weather damage.
