HEMELS is both a manufacturer and an installer, managing the entire process in-house from technical drawings through professional installation.
A pergola is an outdoor shading system built on an aluminum frame with blackout-fabric-covered profiles, providing protection from sun, rain, and wind for year-round use. It can be installed wall-mounted or freestanding, with flat or curved roof options to match different architectural styles. Pergolas are used in residential gardens, terraces, and hotel or restaurant outdoor areas to shelter seating, dining, or relaxation spaces from direct sun and rain. Comfort can be extended with complementary products such as LED lighting, heaters, and wind screens. A standard pergola with fabric covering offers a strong price-to-performance balance, while projects that need higher insulation and weather resistance typically choose an aluminum-louvered bioclimatic system instead. In both cases, the aluminum frame is engineered to the calculated regional wind and snow loads.
Four models: wall-mounted standard pergola, freestanding standard pergola, curved pergola, and arched pergola.
A wall-mounted pergola attaches to a building wall for terraces or balconies, while a freestanding pergola stands on four posts and is positioned independently in a garden.
A curved pergola is wall-connected; an arched pergola stands on its own posts and can be positioned anywhere.
Trusted options include Somfy, Cherubini, A-OK, Mosel, and Cuppon.
Integrated gutters and internal drainage channels route rainwater safely down through the supporting posts.
Yes. The aluminum frame is sized through engineering calculations based on the wind and snow load data for the installation region, an approach consistent with regional load-calculation practice used in structural engineering internationally. Durability can be increased further by adding wall thickness, more rails/supports, or tighter connection spacing — a revision typically recommended for high-wind regions or wide-span projects. The system drains rainwater safely through integrated gutters and internal channels inside the support posts, so no external downspout is visible on the facade. Exact wind and snow load values are calculated per project according to local building regulations for the installation region and shared in writing in the quote prepared after the site survey.
Yes — closed, the panels act as a waterproof roof; opened, they provide shade and ventilation, adjustable to the season.
Yes, LED lighting integration and motor automation are available, controllable via remote, wall switch, or smart home systems.
A standard pergola offers a strong price/performance balance with blackout fabric, while bioclimatic systems provide significantly higher insulation through foam/polyurethane-filled aluminum louvers.
Standard-sized projects are typically completed within 7–10 business days, including production and installation, after the site survey. The process has four main stages: on-site survey and measurement (about 1 day depending on project size), production and powder coating (duration varies by dimensions and stock availability), transport to site, and finally the installation crew's setup (typically 1–2 days for a standard pergola). Custom-sized, wide-span, or multi-module projects can take longer; installations that include bioclimatic systems or motorized components add a commissioning and testing step for the motor/automation. The exact delivery date is stated in writing in the quote prepared after the site survey — thanks to HEMELS's Twin-Factory production model, orders for customers in Turkey and the UAE are fulfilled from the nearest factory, shortening shipping time.
Square meters, motor brand, lighting/automation options, and installation region all affect price; exact pricing is determined on a per-project basis after survey.
HEMELS doesn't publish a fixed price-per-m² list; every pergola project is priced individually based on square footage, motor brand, lighting/automation options, and installation region. Request a free site survey for an approximate budget and a project-specific quote.
An awning is typically a lighter, more flexible shading solution with fabric panels that open and close, while a pergola is a more permanent, durable structure built on an aluminum frame that functions as a year-round, waterproof roof. HEMELS's systems fall into the pergola category.
Aluminum frames can be finished in any RAL color via electrostatic powder coating.
A bioclimatic system (also known as a louvered pergola, louvered roof pergola, or brise-soleil) is a modern exterior system in which motorized or linear-actuator-driven aluminum louvers manage sunlight, airflow, and rain protection through a single roof structure. The louvers rotate to the desired angle to adjust shade, and when fully closed the system protects against rain. Unlike a classic pergola, it uses adjustable aluminum louvers instead of fabric, giving it both durable insulation and a permanent appearance. HEMELS's bioclimatic models include the fixed-angle Tilt Model, the retractable Bio-Rolling, the combined Dual Movement, and the Rolling Roof for sloped applications. When fitted with optional rain and wind sensors, the louvers close automatically as weather conditions change, protecting both the structure and the living space beneath it.
A standard pergola offers price/performance with fabric, while a bioclimatic system delivers superior insulation via foam/polyurethane-filled aluminum louvers.
Tilt Model (angle-adjustable louvers), Bio-Rolling (retracting louvers), Dual Motion (combining both), and Rolling Roof (sloped application).
Yes — with quality systems, the structure remains watertight when the louvers are fully closed.
Yes, it's engineered for high wind speeds; the louver shafts and motor mechanisms are designed for thousands of open-close cycles.
Minimal maintenance is needed — a few soft-brush-and-water cleanings a year, with an annual check of the EPDM seals recommended.
Yes, integrating guillotine or fixed glass panels creates a fully enclosed, year-round living space.
Somfy, Cherubini, A-OK, and Mosel brands are available.
Villa gardens, terraces, pool areas, café/restaurant outdoor spaces, and hotel open areas — for both residential and commercial projects.
Rolling Roof retracts its panels in a single motion; it's lighter and more economical than a full bioclimatic system, and is preferred for large commercial terraces.
HEMELS doesn't publish a fixed price-per-m² list; Rolling Roof pricing depends on area size, motor choice, and installation region. Request a free site survey for an approximate budget and a project-specific quote.
Louvers rotate through a 0–90° range, allowing precise control of light and ventilation.
Yes — the louvers block summer sun for shade and protect against winter cold, indirectly reducing climate-control costs.
Optional rain and wind sensors automatically close the louvers when weather conditions change, protecting the system as well as the furniture and electronics beneath it. When the rain sensor detects the first drops, the louvers move to a fully closed position within seconds; the wind sensor moves the system to a safe position once a set speed threshold is exceeded, preventing structural strain. Because the sensors share the same control/automation infrastructure as the motorized louver system, no additional wiring is required, and they can also be retrofitted onto existing systems. The sensor package is not part of the standard delivery — it's offered as an optional add-on and can be requested during the site survey. It's especially recommended for summer homes, terraces, or commercial spaces that may sit unattended for long periods.
Area size, louver/motor choice, sensors, lighting, and installation region; exact pricing requires a project-based estimate.

A guillotine glass system (also called a guillotine glass balcony system, guillotine window system, or vertical sliding glass system) moves glass panels vertically via a motorized mechanism. Fully opened, it provides safe, easy-to-clean access even on upper floors; closed, it protects against wind, rain, and noise, making balconies, terraces, cafes, and restaurants usable year-round. Offered in Standard and Easy-Clean configurations, panel count and profile dimensions are customized per project. Running on well-known motor brands including Cherubini, Somfy, A-OK, and Mosel, the system can be controlled by remote or a single-touch switch. Glass thickness and type (single or double) are engineered according to the wind load of the installation region, combining aesthetics with structural safety.
Standard Guillotine Glass (a 2- or 3-panel vertical motorized system) and Easy-Clean Guillotine Glass (with inward-tilting panels).
The standard model is hard to clean without exterior access; the easy-clean model tilts its panels inward, so cleaning can be done entirely from indoors.
Either 2 or 3 panels, depending on the opening width determined at the design stage.
Tempered safety glass, which is more impact-resistant than standard glass and breaks into small, blunt fragments if shattered.
Yes, especially double-glazed versions, which retain heat and significantly reduce outside noise.
Cherubini, Somfy, A-OK, and Mosel. Motor selection is determined per project based on panel weight, system height, and frequency of use — heavier or multi-panel systems typically use motors with higher torque capacity. All motorized systems can be operated by remote control or a wall-mounted switch with a single touch, and can optionally be integrated with rain and wind sensors for automatic closing when weather conditions change. European motor brands such as Somfy and Cherubini are known for long service life and quiet operation, which is why they're often preferred for hotel, restaurant, and residential projects. The specific motor brand and model are stated clearly in the technical quote prepared after the site survey.
Periodic glass cleaning and an annual check of the rails and motor are generally sufficient.
Enclosing balconies, closing in terraces, as side panels for winter gardens, and enclosing café/restaurant outdoor areas.
Yes — combining it with a bioclimatic or Rolling Roof system creates a fully enclosed, year-round space.
Yes, tempered safety glass and anti-pinch measures reduce the risk of injury.
Glass type (single/double), panel count, profile dimensions, motor choice, and total area size.
HEMELS doesn't publish a fixed price-per-m² list; guillotine glass balcony pricing depends on glass type (single/double), panel count, profile dimensions, motor choice, and total area size. Request a free site survey for an approximate budget and a project-specific quote.
A winter garden (also called a glass conservatory) is an open garden, terrace, or balcony area enclosed with glass and aluminum systems to create a usable, year-round living space.
An aluminum-framed system available with 24mm insulated glass or 20mm sandwich panel options, providing full year-round insulation in either wall-mounted or freestanding configurations.
The concepts are closely related — "veranda" is HEMELS's product name, while "winter garden" is the general term for an enclosed glass living area.
Yes, thermally insulated glass systems, properly installed, maintain a comfortable interior temperature through winter.
Aluminum profiles with 24mm insulated glass or 20mm sandwich panel options.
A relaxation area, office, hobby room, guest space, or café/restaurant seating — and it adds to your property's value.
Yes, guillotine glass can be integrated with the veranda system.
The process runs through a free site survey/measurement, technical drawings and 3D design, production, then installation; the timeline depends on project scale and any permit requirements.
A system in which zippered fabric edges are integrated into aluminum side rails, preventing sagging in windy conditions and offering comprehensive protection from sun, wind, rain, dust, and insects.
A-OK, Cuppon, Somfy, and Cherubini; operable via single-touch or remote control.
Aluminum rails/cassettes in any RAL scale color, with the fabric color chosen to match your space.
A system that protects vehicles from sun, rain, hail, and dust, built on a steel or aluminum frame with ACP, aluminum louver, or timber cladding options.
Yes, EV charging stations, solar panels, and LED lighting can all be integrated into carport systems.
A modular cover system whose sections slide on wheeled aluminum or steel rails, collapsing into minimal space; built with UV-protected polycarbonate or tempered glass and used for pools, terraces, and gardens.
Structures in which PVC, PTFE, or ETFE membranes are stretched over steel cables or rods, spanning wide, column-free areas.
A three-dimensional steel lattice structure that distributes load evenly across every node, enabling large, column-free spans — used for terminals, sports halls, and shopping centers.
Mosque courtyards, industrial facilities, and sports venues that need a motorized, waterproof solution resistant to wind and snow.
A steel or aluminum load-bearing structure clad in waterproof fabric or membrane, operated motorized.
Timelines vary from a few weeks to several months, depending on area size, structural calculations, and production capacity.
Yes, every custom structure system is engineered and designed to the dimensions and intended use of the specific site.
Area size, system type, profile choice, glass thickness, motor brand, color, and lighting features all factor in; rather than a fixed price list, we prepare a custom estimate after a site survey.
Yes, a complimentary site survey and measurement is provided on request, followed by a project-specific estimate.
Approximate dimensions (width x length x height), installation location (garden, terrace, balcony), the system type you want, and any special requests (color, motor, lighting).
It depends on the quote's scope; turnkey quotes typically include installation, while regional shipping and labor may be itemized separately.
Tax inclusion is clarified in the quote document; get in touch via our contact page for exact pricing.
Product cost plus shipping, customs, and optional on-site installation; our Turkey and UAE facilities help reduce costs for nearby regions.
Payment terms vary by project — an advance deposit plus interim payments tied to production and installation milestones are detailed during the quote process.
It depends on your use case: a standard pergola for economical shading, a bioclimatic system for comfort and automation, or a veranda/winter garden for a home-like feel — we recommend the right fit after a site survey.
Standard projects typically within a few days; large-scale, engineering-intensive projects (space frames, tensile structures, large area systems) require more preparation time.
Installation is carried out by HEMELS's own expert teams or authorized regional partners.
Ground condition, electrical infrastructure (for motorized systems), and water drainage should be assessed; our survey team provides guidance on this.
Warranty length varies by product group and component; for example, the aluminum frame and electrostatic powder coating and the motor/automation components come from different manufacturers and may carry different warranty terms. Aluminum profiles and the powder-coat finish are covered against material and workmanship defects; motor brands such as Cherubini, Somfy, A-OK, and Mosel are covered under their own manufacturer warranties. For the warranty to remain valid, installation must be carried out by HEMELS's own teams and the recommended usage conditions must be followed. Damage caused by natural disasters, misuse, or unauthorized modification is excluded from coverage. Exact warranty terms for each product group are detailed in the sales contract and quote prepared for every project.
The motor brands we use carry their own manufacturer warranties; contact us for an assessment — a free replacement is provided under warranty, or a quote is issued if it falls outside warranty.
Generally, 1–2 simple cleanings a year (soft brush and water) plus a visual check of seals and drainage is sufficient; periodic motor checks are also recommended.
No — aluminum is naturally corrosion-resistant, and the electrostatic powder coating adds further weather protection.
Yes, aluminum is more resistant to salt and humidity than steel; stainless fasteners are used in harsher coastal conditions.
Modular systems (bioclimatic, space frame) may allow expansion depending on existing load capacity and connection points — contact us for an evaluation.
The electrical line required for motorized systems is generally arranged by the building/facility owner.
Yes — depending on the motor brand, control is available via remote, wall switch, mobile app, and smart-home integrations such as KNX, Google Home, and Alexa.
