Question 1

What types of projects does Namakaran Fakher Engineering Co. take on?

Accepted Answer

Our focus is on office and headquarters buildings, commercial projects and malls, residential and mixed-use towers, and governmental, educational, and cultural buildings. That said, we also review select smaller special projects in some cases (for example, the facade of a luxury residential building or a distinctive villa), especially when the facade type itself is distinctive (curtain wall, spider, dry ceramic, composite, HPL, etc.).

Question 2

What is the minimum facade area for accepting a project?

Accepted Answer

The minimum area for a project to make economic sense varies by system. In general: for curtain wall and spider systems, typically from around 500–700 m² and up; for dry ceramic, HPL, and composite, typically from around 300–500 m² and up. Special projects with smaller areas can still be reviewed case by case, depending on location and conditions. We recommend sending us your project information so we can assess it individually.

Question 3

Which cities do you work in?

Accepted Answer

Our office is in Tehran, but our projects have been executed in cities across the country (Tehran, Saveh, Kashan, Tonekabon, Sanandaj, Isfahan, and more). Provided the work is technically and economically justified, we have no geographic coverage restrictions.

Question 4

How do you calculate facade installation pricing?

Accepted Answer

Facade installation pricing depends on several factors: system type (curtain wall, spider, dry ceramic, composite, etc.), project area and height, material type (brand, thickness, quality), the complexity of the facade form, and the geographic location and site conditions. Before quoting a final number, we prepare a line-by-line estimate in which the costs of materials, labor, equipment, transportation, and margin are set out transparently.

Question 5

What information should we send you to start a collaboration?

Accepted Answer

The minimum information required: project location and type of use, architectural drawings (PLAN, SECTION, ELEVATION), the intended facade or material type (if already decided), the approximate facade area, and the project status (in design, under construction, or existing and due for renovation). The more complete the information, the more accurate — and faster — the estimate we can provide.

Question 6

What kind of warranty and guarantee do you offer on your work?

Accepted Answer

Depending on the project type and contract, we typically provide a multi-year warranty (for example, 3 to 5 years) for the substructure and mechanical connections, plus a defined period aligned with the system type for waterproofing and joints. Materials (such as composite, HPL, glass, etc.) also carry their own separate factory or supplier warranties, which are included in the contract and the attached documents.

Question 7

Do you only build, or do you also provide design services?

Accepted Answer

Both. We offer “executive design and shop drawings + value engineering” services as well as full installation. Depending on the project's needs, we can deliver executive design only, or take on design + construction as a complete Design & Build package.

Question 8

What differentiates you from the intermediary companies that advertise on Google?

Accepted Answer

Many companies are in fact only intermediaries and do not carry out the actual installation themselves. At Namakaran Fakher Engineering Co.: we perform the installation directly, with our own teams; every system we present on this website has been installed by us personally over the years; and there is complete integration between the technical office team and the site execution team. This reduces the risk of a gap between “what is on paper” and “what is actually built on site”.

Question 9

Is a phased contract possible (for example, design first, installation later)?

Accepted Answer

Yes. Many of our collaborations start exactly this way: first an executive design and value engineering contract is concluded; after approval by the client and the consultant, a full installation contract can be signed as well, if desired.

Question 10

How can we see your portfolio and execution details?

Accepted Answer

Through the “Projects” page you can view our key projects. The “Detail Library and Videos” page also publishes a selection of sample details and videos from our construction sites and exhibitions. For access to more complete details, you can contact us directly for a dedicated exchange.

Question 11

Is a glass handrail safe? Which type suits balconies and lobbies best?

Accepted Answer

Yes — provided it is built to standard. Our handrails use laminated tempered glass (8+8 or 10+10), which remains held on the PVB interlayer if it breaks — unlike tempered-only glass, which is not recommended. For lobbies and stairs, the German-style stainless handrail or a CNC metal handrail is a popular choice; for tower balconies and terraces, we recommend the fixed-point system or a frameless system with embedded base shoes (in new construction) or surface-mounted base shoes (in renovations). The final choice is determined in the consultation session based on the project phase, the architectural style, and the budget.

Question 12

How heavy is an aluminum decorative metal ceiling (stretch metal or punched metal), and can services still be accessed?

Accepted Answer

Decorative metal ceilings are among the lightest decorative ceilings on the market — their load is on the order of a few kilograms per square meter, and because of that light weight they add no noticeable extra load to the structure. Service access is planned in from day one on the drawings: over the service points (ducts, coils, hatches), openable panels with clips and a serviceable frame are installed so maintenance can be performed without demolishing the ceiling.

Question 13

Do operable facade louvers need a motor and electricity? Is their upkeep demanding?

Accepted Answer

Operable louvers need a servo motor or rotating shaft and a power feed; control can be via a panel, a remote, a time schedule, or light and wind sensors (even integration with the building's BMS). Fixed louvers, by contrast, require no building services at all. Louver upkeep is light: periodic servicing of the motors and seals once a year, and washing the blades just like the facade itself. We design a serviceable detail so that a motor can be replaced without dismantling the entire band.

Question 14

Is facade renovation possible without full demolition? Doesn't facade washing damage the material?

Accepted Answer

Yes — in most cases targeted repair instead of complete demolition is carried out at a fraction of the cost and without evacuating the building: waterproofing and re-sealing, replacement of damaged panels, anti-rust treatment and substructure reinforcement, and de-warping of panels. Washing is likewise done with “specialized facade cleaning agents” matched to each material — strong alkaline detergents are forbidden on composite and glass, and we follow a material-specific protocol (agents, concentration, full rinsing) and hand over documented records. First, a technical assessment with a water test is performed so that the actual defects become clear.
