Frequently Asked Questions
► Is it worth getting bifold doors for your patio or garden?
Aluminium bifold doors from Roof Maker improves your home. With the installation of these secure, robust doors, you can increase the airflow of your home, create a better connection with gardens and patios, and introduce more natural light. This makes bifold or any other aluminium folding doors a sound investment.
► What is the difference between a bifold door and a folding door?
Bifold doors are usually glazed with large glass panels that let plenty of light in. These doors open with a concertina and can be tailored to open in or out. This variety makes bifolds ideal for a wide range of door sizes, from smaller homes to grand patios.
Sliding doors on the other hand are a series of glass panels that slide in front of one another. These can be more difficult to use and are limited in their application.
► Do bifold doors add value to your property?
Aluminium bifold doors introduce light and airflow into your home, as well as offering a feature window over your garden and other green spaces. As such, bifold doors on a patio, garden, or other private exterior space can be hugely advantageous in enticing potential homeowners.
Optional Upgrades
A low threshold that connects your indoor and outdoor floors seamlessly or a rebated threshold if you need better weather resistance.
Upgrade to laminated glazing, or subtle tinted glass – available in both our bifold and rooflight range.
Upgrade to laminated glass for additional safety and security, combine with subtle blue tint glass for UV protection of furniture and fabrics.
