Frequently Asked Questions

Choosing the type of patio door largely depends on your taste & preferences, the space where you are about to install the door, and lastly your home requirements.

While folding patio doors are great options for opening up your home as well as creating an inside-outside feel to a property, sliding doors offer better views when closed. That’s because sliding patio doors come with bigger glass panes with less uPVC or aluminum showing.

You may also check out our French door options that provide great views on beautiful summer days. These both-side opening patio doors allow a larger opening than a standard PVC sliding door.

Being one of the largest patio door suppliers for Patio Doors Belfast, and Patio Doors Northern Ireland (Patio Doors NI), we offer a wide range of door types that are as follows:

  • Bifold doors
  • Sliding doors
  • French Doors

Our extensive collections of patio doors are made up of either uPVC or aluminum materials. Usually, most of the bifold doors that we supply and install are made up of aluminum. Our sliding doors are made up of uPVC or aluminum depending on our client’s requirements and French doors are made up of uPVC materials.

Perhaps you must be aware that suppliers of patio doors Northern Ireland (Patio Doors NI) and Patio Doors Belfast need to adhere to strict safety guidelines. That said, availing of patio doors at Smart Homes NI will provide you with a PAS certification along with a wide variety of features that will ensure your home security. These locking features include:

Multi-point locking system – This mechanism provides multiple locking points around the frame, thus making force entries even more difficult.

Internal beading – This allows the glass panes to be inserted on the inner side of the window frame rather than the outer side, thus it can only be removed from the inside. While traditional windows were actually beaded externally, we offer internally beaded windows with improved security features on the frames.

Key operated handles – This mechanism locks the window, thus eliminating every chance of force entry externally.

Secured by design – Being an official UK Police scheme and certification, this offers high levels of security for a variety of home-improvement products including our range of doors and windows.

As we offer customized patio doors and windows based on your home requirements, we take some time to manufacture the products from the scratch. This means that the estimated installation timeline can vary depending upon the size, sections, number of doors, etc. Further, it may also depend upon the number of orders our factory is currently processing. 

However, the usual timeframe from survey to fitting is around 8 to 10 weeks.
