Tailored Applications for Any Architectural Style
Our custom-manufactured sliding systems are completely bespoke, tailored to fit your specific architectural dimensions and functional requirements:
- UPVC Sliding Patio Doors: Transform the way you use your home. These doors create a stunning, wide-open transition to your backyard, outdoor kitchen, deck, or garden area. Because they slide parallel to the wall, they don't interfere with your patio furniture layout, making them perfect for entertaining guests.
- UPVC Sliding Door for Balcony: Space is often at a premium in apartments and townhouses. Traditional hinged doors eat up valuable square footage. A sliding door maximizes the usable footprint of your living room or bedroom. Furthermore, our tight weather seals ensure that high-rise balconies are completely protected against driving rain and high winds.
FAQ
Q: How long do UPVC sliding doors typically last?
A: High-quality UPVC is incredibly durable. With proper installation and basic maintenance, our doors have an expected lifespan of 25 to 35 years without losing their structural integrity or color stability.
Q: Are UPVC external sliding doors secure against intruders?
A: Yes. Security is a primary focus. Our doors come standard with anti-lift blocks, multi-point locking mechanisms that secure the door at several points along the frame, and toughened safety glass that is incredibly difficult to break.
Q: Do sliding PVC doors require a lot of maintenance?
A: Not at all. UPVC is virtually maintenance-free. To keep them functioning perfectly, simply clean the tracks of dust or debris a few times a year and wipe the frames with a damp cloth. There is no need for sanding, varnishing, or repainting.
Q: Can I use a UPVC sliding door for a balcony in a high-rise building?
A: Absolutely. UPVC sliding systems are ideal for balconies. They save internal space since they don't swing open, and our profiles are structurally reinforced with galvanized steel to withstand the high wind loads typical of elevated apartments.
Q: How energy efficient are UPVC sliding patio doors compared to aluminum?
A: UPVC is a natural insulator, whereas standard aluminum is a conductor of heat. While thermally broken aluminum doors are efficient, multi-chambered UPVC doors generally offer superior thermal insulation at a more cost-effective price point, preventing drafts and condensation.
Q: Are custom sizes available for large patio openings?
A: Yes, we manufacture all doors to order. Whether you need a standard two-panel slider or a massive four-panel configuration for a panoramic view, we engineer the frames and hardware to support your specific dimensions safely.
Q: Will the color fade under intense sunlight?
A: No. We use UV-stabilized UPVC profiles that are rigorously tested against harsh sunlight. This ensures the frames will not yellow, fade, or become brittle over time, even on south-facing external walls.
