What do I need to send to start a custom aluminum window or door order?

Architectural drawings, a BOQ or simply your opening sizes are enough to start. Our engineers select the profile series, glass and hardware, then issue shop drawings for your approval before production begins.

Can I check quality before placing a bulk order?

Yes. You can order corner samples or a full-size sample window to verify finish, hardware operation, sealing and build quality before mass production.

Which certifications and test results are available?

Our 76M tilt and turn system holds an AS 2047 StandardsMark Licence (SMK41686), our quality management is certified to ISO 9001:2015, and CE conformity is available. Complete national test-center reports can be provided on request, and products can be configured for NFRC, CE or AS 2047 target markets.

What is the difference between your OEM and ODM service?

With OEM, you supply the design and specifications and we manufacture to your exact standard with IP protection. With ODM, you choose from our tested product library and we apply your logo, labels and packaging for a faster, lower-cost launch.

Which markets do you ship to and how are windows packed?

We ship to the USA, Europe, the Middle East, Central Asia and Australia. Every unit is protected with corner guards and film wrap and loaded to prevent movement during sea freight.

What glass and finish options are available?

Options include Low-E, argon-filled and laminated insulating glass, thermal break profiles with PA66 strips, and PVDF, powder-coated, anodized or wood-grain finishes in custom colors.

Localized Applications

Tailored Pivot Entrance Systems for Diverse Bulgarian Climates

Bulgaria features three distinct architectural and climatic zones. Crestor customizes alloy anodizing, glass assemblies, and thermal breaks to fit each regional requirement seamlessly.

1. Black Sea Coastal Villas (Varna, Burgas, Sozopol)

Environmental Challenge: High atmospheric humidity, aggressive saline air mist, and severe autumn coastal winds.

Crestor Customized Solution: Heavy-duty aluminium pivot doors treated with C5-marine grade PVDF coating or 25-micron anodization. Hardware components utilize 316 stainless steel and concealed heavy-duty hydraulic floor pivots to stop salt-induced oxidation permanently.

2. Urban Commercial & Luxury High-Rises (Sofia & Plovdiv)

Environmental Challenge: High pedestrian traffic, strict acoustic insulation demands (city noise), and modern architectural aesthetics.

Crestor Customized Solution: Oversized grand pivot doors handling sash weights up to 500 kg. Features triple-glazed acoustic laminated Low-E glass, integrated motorized biometric/facial recognition locks, and hidden closer spindles for sleek minimalist entrance facades.

3. Mountain Resorts & Alpine Chalets (Bansko, Borovets)

Environmental Challenge: Sub-zero winter freezes (-20°C), heavy snow loading, and high thermal differential between indoor and outdoor air.

Crestor Customized Solution: Multi-chamber thermal break profiles with 34mm PA66 glass-fiber reinforced nylon strips. Combined with warm-edge glass spacers and argon gas filling to prevent ice formation on interior frames and eliminate energy loss.

Key Trends Driving Bulgarian Architectural Door Procurement in 2026

The Bulgarian construction market has shifted dramatically away from standard PVC swing doors towards oversized architectural entrance statements. Key structural demands include:

• Oversized Minimalist Sashes

Architects in Sofia are specifying pivot doors reaching 4.5 meters in height and 2.2 meters in width, requiring high-tensile 6060-T6 aluminium alloy framing.

• Smart Access Control Integration

Seamless integration of German electro-mechanical multi-point locking systems compatible with finger-scanner, smartphone app, and KNX smart building automation.

• Dual-Finish Aesthetics

Exterior surfaces rendered in weatherproof textured metallic powders (such as AkzoNobel or PPG) combined with real interior wood veneer overlay.

• Seamless Flush Floor Transition

Sub-floor concealed drainage channels paired with automatic drop-down bottom seals to achieve zero-barrier accessibility without water leak risks.

Procurement Guidance

Frequently Asked Questions by Bulgarian B2B Buyers & Importers

Clear answers regarding shipping, custom clearance, technical compliance, and order customization for Bulgarian architectural projects.

What structural & thermal certificates are provided for custom clearance in Bulgaria?

Every order shipped to Bulgaria includes full CE Declaration of Performance (DoP) documentation, test lab reports verifying compliance with BDS EN 14351-1, ISO 9001 quality certificates, and comprehensive structural shop drawings required by local Bulgarian municipal building inspectors.

How does Crestor handle sea freight logistics to Port of Varna and Port of Burgas?

We coordinate containerized shipping directly from Chinese ports (Qingdao or Shanghai) to major Bulgarian ports including Varna West and Burgas. All pivot doors are packed in heavy-duty export-grade plywood crates with corner guards, protective anti-scratch films, and desiccant bags to prevent moisture damage during transit (typical voyage: 25-35 days).

Can we order fully customized offset pivot hardware and custom sash sizes?

Yes. Crestor offers complete OEM/ODM engineering customization. You can select asymmetric or center pivot axis points, German Dormakaba or FritsJurgens pivot floor springs, integrated LED perimeter lighting strips, and custom dimensions up to 5 meters high.

What is the Minimum Order Quantity (MOQ) and sample validation process?

We support both single luxury residential project orders and volume commercial developments. Corner connection samples or full-size prototype pivot doors can be manufactured and air-freighted to your address in Sofia or Plovdiv for design and material verification prior to mass production.

How do your thermal break pivot doors prevent draft and water leaks in winter?

Our pivot doors utilize a continuous three-stage EPDM weather-stripping gasket design combined with an automatic drop-down mechanical bottom seal that lowers when the door closes. This guarantees air tightness grade 8 and water tightness up to 700 Pa even under high wind pressures.

What warranties are provided on Crestor aluminium pivot door assemblies?

Crestor provides a comprehensive 5-year structural warranty on aluminium extrusions and hardware mechanisms, alongside a 10-year warranty against PVDF coating discoloration or chalking, backed by continuous spare parts replacement availability.
