The aluminum entry door for terraces from DERCHI is a collection of thermal break aluminum door and window systems designed to connect indoor living spaces with outdoor terraces, gardens, and balconies. Engineered for energy efficiency and structural integrity, this range includes folding, sliding, bifold, casement, and awning configurations to suit diverse project requirements.
- Thermal break profiles and energy-efficient glazing help manage interior temperatures year-round
- Large opening capabilities — some systems span up to 18 meters wide — for unobstructed terrace access
- Fully customizable dimensions, finishes, glass, and hardware with B2B project support
Product Details
The aluminum entry door for terraces uses 6063-T5 aluminum profiles with multi-chamber design and PA66 thermal breaks to separate interior and exterior frames, reducing heat transfer. EPDM seals and triple-sealing on select series deliver reliable air and water tightness for exposed terraces. Glazing options include tempered, laminated, and Low-E glass with argon-filled cavities for improved thermal performance.
Compared to standard patio doors, these systems withstand heavy use and wind loads. Folding models span up to 18 meters, while the Q15 sliding door supports panels up to 3 meters wide with optional motion sensors and app control. Each configuration is chosen for the terrace layout, from compact balconies to commercial rooftops.
Product Features
- Thermal Break Construction: PA66 reinforced nylon barriers reduce conductive heat loss, helping maintain indoor comfort and lower cooling loads when terrace doors are closed.
- Heavy-Duty Hardware: Multi-point locks and brand handles (CMECH, Kerssemberg, WEHAG) ensure secure, smooth operation even on oversized folding or sliding sashes.
- Advanced Weather Sealing: EPDM gaskets and optional triple seals with water swell strips protect against wind-driven rain, keeping interior floors dry during storms.
- Energy-Efficient Glazing: Double or triple glazing with Low‑E coatings and argon fill reduce U‑factors; laminated options also improve sound insulation for urban terraces.
- Flexible Opening Styles: Folding, sliding, bifold, tilting, and awning configurations let architects optimize space, ventilation, and the visual flow between rooms and terraces.
- Durable Finish: Powder coating, anodized wood grain, or PVDF coating resists corrosion and fading; custom colors match project façades and withstand UV exposure.
Customizable Styles
- Glass Options: Tempered, laminated, tinted, reflective, Low‑E; argon-filled IGUs; impact and acoustic configurations discussed upon request.
- Frame Colors & Finishes: Caramel Coffee, Deep Coffee, Black Crystal Stone, Quartz Gray, Starry Sky Black, Black Skin; custom RAL or anodized wood grain available.
- Sizes & Dimensions: Sash widths 500mm–4000mm, heights up to 6000mm; openings up to 18m for folding systems — final dimensions confirmed from project drawings.
- Opening Configuration: Folding, sliding, bifold, casement, tilt-turn, awning; top-hung or bottom-rolling tracks selected per threshold and load.
- Hardware & Accessories: CMECH, Kerssemberg, WEHAG, HOPO matched to series; screens, blinds, smart controls integrated during specification.
Hardware Accessories
- Multi-Point Locking: Shootbolt or hook locks engage multiple points along the sash, securing tall panels and compressing seals evenly.
- Stainless Steel Rollers: Heavy-duty sliding/folding hardware with sealed bearings; anti-swing upper wheels and load-rated lower rollers for panels up to 500kg.
- Ergonomic Handles: Lever/pull handles from CMECH, Kerssemberg, WEHAG, HOPO integrate with cylinder locks for comfortable, secure operation.
- Concealed Hinges: Adjustable stainless or aluminum hinges maintain clean lines and are protected from weather; allow post-installation fine alignment.
- EPDM Weather Seals: Extruded EPDM gaskets in frame and sash; co-extruded water swell strips expand when wet to boost water tightness.
Basic Parameters
| Performance Item | Available Information | Buyer Notes |
|---|---|---|
| Thermal Insulation | U‑factor as low as 0.28 (93 bifold and Q15) for standard configurations; Uw range 2.0–3.5 W/m²K for 78 series. | Request U‑value certificates for the exact glass package and size; values vary with frame ratio and glazing choice. |
| Wind Pressure Resistance | Tested up to 4.5 kPa on 93 bifold; up to 5.0 kPa on 78 series; Q15 rated 4.5 kPa. | Confirm design pressure rating matches local code and exposure; higher ratings may be achievable with thicker profiles. |
| Water Tightness | 450 Pa for 93 bifold and Q15; 500–700 Pa for 78 series. | Verify suitability for driving rain; sill drainage design is essential for terrace exposure. |
| Air Tightness | 1.8 m³/(m·h) on 93 bifold; Class 3 on 78 series. | Air leakage affects HVAC efficiency; request air permeability reports for large multi‑panel combinations. |
| Sound Insulation | 30 dB for 93 bifold; Rw 35–40 dB for 78 series; ≥35 dB for S63 awning; 35 dB for Q15. | Actual sound reduction depends on glass thickness and seals; specify acoustic performance during design. |
