Aluminium Sliding Door

The quality of an aluminium sliding door is determined by how the door functions. To ensure quality, consider the following:
Operation — Check how smoothly the rollers move in their tracks and how much effort it takes. The door should feel snug in its tracks, but move easily. It should feel more like it’s floating than sliding.
Security — Examine the locking system. Hardware selections vary, and the best doors will feature quality hardware. Locks should meet or exceed local forced–entry code.
Energy Efficiency — Make sure the sliding door you buy is well insulated and comes with the appropriate energy-saving glass to reduce your heating and cooling costs.
