FAQ
Q: What is the difference in application between slimline aluminium sliding doors vs bifold doors?
A: Slimline sliding doors are ideal when the priority is uninterrupted views when the doors are closed, thanks to the 20mm sightlines and large glass panels. Bifold doors are better suited when the client wants to completely open up an entire wall to the outside. Sliding doors also require less operational clearance since they do not stack inward or outward.
Q: How do you ensure weatherproofing with a slimline aluminium sliding door with a flush floor track?
A: Our flush track systems incorporate concealed sub-sill drainage and EPDM weather gaskets. The track must be integrated with the exterior drainage channel during installation to ensure water is directed away from the property, making it fully weather-tight even in exposed locations.
Q: Are frameless glass slimline aluminium sliding doors secure?
A: Yes. While the frames are minimalist, the security is not. The system utilizes heavy-duty aluminium profiles, anti-lift blocks to prevent panels from being pried off the tracks, and robust multi-point locking mechanisms that engage directly into the solid frame.
Q: What is the lead time for custom size slimline aluminium sliding doors?
A: For standard RAL colors (like Anthracite Grey or Jet Black), our standard B2B fabrication lead time is 4 to 5 weeks from sign-off of the technical drawings. Custom RAL colors or marine-grade powder coating will add approximately 1 to 2 weeks to the schedule.
Q: How difficult is the installation process for these ultra-slim systems?
A: Because the frames are incredibly slim, the glass makes up the majority of the weight. The outer frame is assembled and fixed into the aperture first. The glass is often bonded to the sash profiles in the factory, meaning you will need specialized lifting equipment (like a spider crane or glass vacuum lifters) on site to position the heavy panels into the tracks safely.
Q: Can these doors achieve the thermal efficiency required for new build regulations?
A: Absolutely. The thermal efficiency of our slimline aluminium sliding doors is achieved through wide polyamide thermal breaks separating the inner and outer aluminium profiles. When paired with low-E, argon-filled double or triple glazing, the system easily complies with stringent energy regulations.
Q: Can we order just the aluminium frames without the glass?
A: Yes. For our trade and B2B clients, we offer the option to supply "frame-only" kits. We will provide the exact glass deductions and specifications required so you can source the glass units from your preferred local supplier, saving on shipping costs and logistical risks.
