Buyer's guide: sliding patio doors
Sliding doors come in a few types. A standard sliding door is the most affordable. A lift-and-slide door (elevadora) lifts off its seals as you open it, so very large panes move easily and seal tightly when closed. Tilt-and-slide doors (osciloparalela) also tilt for ventilation. Minimal-frame systems give the biggest glass area and cost the most.
Most large sliders are aluminium. On the coast they should have a thermal break and a coastal-grade finish. Ask how the track drains: a flush threshold looks good, but water must have somewhere to go on an exposed terrace.
Check the glass. Big panes need toughened or laminated safety glass, and low-e solar-control glass keeps a sunny living room cooler. Ask whether insect screens and a lock or security bar are included, and how the company will bring large panes into an apartment.
Questions to ask before you sign
- Is the door a standard slider, lift-and-slide or tilt-and-slide?
- Does the aluminium have a thermal break?
- How does the bottom track drain?
- What safety and solar-control glass is included?
- Are an insect screen and locks included?
- How will large panes be brought into the property?
Common questions
What is a lift-and-slide door?
A lift-and-slide (elevadora) door lifts slightly off its seals when you turn the handle, so even heavy panes slide easily, then drops back onto the seals to close tightly. It suits large openings and seals better than a standard slider.
Can sliding doors have a flush threshold?
Yes, many systems can be fitted with a flush or very low threshold. On an exposed terrace you need good drainage in front of the door, so ask the company how it handles heavy rain.
How big can a sliding door pane be?
It depends on the system. Lift-and-slide and minimal-frame systems take much larger panes than standard sliders. Ask the company for the maximum size of the system it is quoting.
