We have discovered – that if you’re like our most discriminating sliding door clients – what attributes you desire in your sliding door. If so, here’s what you want:
I want a sliding door that is lightweight.
One of the reasons that sliding doors fail is due to the fact that they are too heavy for the hardware to adequately handle the stress of slinging a sliding door back and forth over time. Another issue with weight (especially for large sliding doors) is strain on the structure itself, which could compromise the home or building that hosts your sliding door.
I want a sliding door that is strong.
Many sliding doors that are regularly available via retail outlets may be lightweight, but if they are, usually cannot take much abuse. That’s why house rental agencies are constantly replacing sliding doors in-between renters. It doesn’t take much to damage a standard sliding door, and if they could be repaired it would be cost-prohibitive but you could never repair that sliding door to achieve its original strength.
Sliding Doors Big Large Oversize
I want a sliding door that will last.
Unless you like to replace your sliding doors periodically, why should you? If your sliding door was built like any other sliding door, then it will likely bend, warp or twist over time. Especially if you have twin sliding doors; you want your sliding doors to be straight and true for the long haul.
I want my sliding doors to provide some privacy.
Most people who have had experience with run of the mill sliding door don’t expect much in the way of privacy. When sliding door customers are looking for sound-deadening sliding doors, they find Sing Core for a variety of applications, including sound proof sliding doors.
I want a sliding door that is not going to let the heat out.
Energy savers know that in most cases, a sliding door is the weakest point of energy loss. Sing sliding doors are packed with insulation to keep the environments on either side of the sliding door uncompromised.
Is there such a thing as an Eco-friendly sliding door?
Yes, in this day and age, planet conscious individuals are seeking out ecologically responsible components and Sing sliding doors are the only affordable Eco-friendly, lightweight high-strength insulated doors that are designed to last for years without compromise.
We humbly agree with our high-end clientele that we do help build the best sliding doors in the world.
