Our design and engineering department is led by our Managing Director, a licensed Professional Engineer in the USA and Chartered Professional Engineer in Australia.  He has over 16 years of experience including design, engineering, construction and building envelope failure analysis and is a recognized building code expert in the USA.

Our design department is experienced in shop drawing preparation of shop fronts, curtain walls, doors, windows and frameless glass systems using 2D and 3D CAD systems.


We are experienced in testing and failure analysis of building envelope systems.  The Managing Director of REC Aluminum has years of experience in building envelope testing and failure analysis including the use of destructive and non-destructive testing methods. 

Our aluminum doors and windows are tested in the factory and in the field for water penetration using building code accepted standards such as AAMA and ASTM.  Our water spray testing equipment is calibrated and the testing method we employ meets USA industry testing standards.

Our frameless glass handrail system has been impact tested and tested for distributed and point loading conditions in accordance with International Building Codes, such as the USA IBC. 


REC has developed close working relationships with material and logistics companies throughout southeast asia. We work closely with material suppliers and logistic companies in Thailand, Hong Kong and the Peoples Republic of China.

Our expertise gained in working with our partner suppliers and logistic companies in southeast Asia ensures that our manufactured products are properly prepared, shipped, and delivered in accordance with international customs requirements and thus delivered and installed on schedule.


REC operates an advanced manufacturing facility located in Samut Prakan, Thailand.  We utilize CNC machining centers, CNC saws, digital double miter saws, punching machines, 2D and 3D CAD to generated cut sheets and fabricate our door and window systems.  Our CAD and CNC fabrication process ensures that our systems are fabricated to tolerances within +/- 2 mm.

REC Door and window systems are fabricated in our shop and delivered to the jobsite for quick installation.  Fabrication of our door and window systems at our factory ensures that critical seals are made in our factory. 


REC fabricates and installs door and window systems, curtain wall systems, frameless glass hand rails and window walls throughout Thailand.  Our installation team follows internationally accepted standards for the installation of our fenestration systems and provide post water spray testing to guarantee quality and provide our customers peace of mind.    

Recently completed commercial projects include an 8 story luxury condominium building on the water in Na Jomtien Beach and an 8 Story apartment building utilizing our frameless glass balcony balustrades and our window wall system.

Recently completed residential projects include complete door and window replacements for luxury condominiums located in Bangkok, residential houses in Hua Hin, Chiang Mai and Phang Na. 

All of our door and window systems are fabricated at our fully equipped factory in Samut Prakan, Thailand.  
REC’s fabrication factory is equipped to quickly and accurately process large volume custom orders.  Some of our equipment includes advanced CNC machining centers, CNC machine saws, digital double miter saws, punching machines, glass lifting machines, glass edging machines etc.

We have multiple equipment lines for our various systems which ensures high production capacity, quality, and on-schedule installation.

Our centrally located fabrication factory provides our clients with the peace of mind and flexibility that project changes can be accomplished in a timely and inexpensive manner.  

Deluxe System
Door and window systems are designed to provide weather protection from the external environment, sound proofing, thermal control, security, and to functionally separate spaces for living.

Our Deluxe system door and windows are designed to provide superior water proofing with a secondary water slot drainage to weep moisture.  Our systems are assembled and water spray tested in our factory and in the field after installation to provide superior water proofing and peace of mind.

Sound Proof Windows
Our deluxe systems can be glazed with different glass types to increase the sound proofing of condominiums, residences and commercial properties.

Sound is transmitted via air through vibrations.  Doors and windows which do not seal well or are not fitted with the proper glass, allow noise to enter almost unimpeded.

Our deluxe door and window systems are multi-locking systems which provide compression gasket sealing to limit noise and air intrusion.   We design and fit our door and window systems with laminated glass of varying interlayer thicknesses and glass lite thicknesses to damp noise causing vibration from a wide range of frequencies.

In addition to selecting the appropriate door and window systems and glazing, the installation and anchoring of the system plays an important part in noise reduction.  REC is experienced in providing design solutions to reduce noise problems and in implementing the solutions in the field.   

Energy Efficient Windows
REC door and window systems use low-e coated tempered insulated glass with argon gas fill when our customers are interested in high energy efficient doors windows.

We use industry accepted software from the USA for analyzing window thermal performance and can simulate U-values for a wide range of glazing types, low-e coatings, gas fills, and spacer widths to meet our customer requirements.

Energy efficiency is described via U-Factor, which is a measure of the air-to-air heat transmission (loss or gain) due to thermal conductance and the difference in indoor and outdoor temperatures.  Basically, the U-factor measures how much energy is transferred through a glazed opening, within a certain amount of time and having a temperature gradient.

A lower U-factor means that less heat is transmitted through the glazing opening.  A higher U-factor means more heat is transmitted through the glazing opening.  So, when selecting products for thermal energy efficiency, consider products with a lower U-factor.

In addition to U-factor (U-value), solar radiation will also increase internal heat gain.  Thus, products with a low SHGC (solar heat gain coefficient) and low U-factor will better contribute to overall energy efficiency.

As a reference point, a single pane 6 mm clear glass has a U value of 1.04 whereas a double pane insulated glass with a 6 mm spacer/argon gas/low-e coating has a U-value of 0.35. The rate of heat transfer is reduced significantly with low-e coated insulated glass with gas fill. 

The easiest way to obtain a subjective sense of the difference would be to measure the temperature of the inside pane of a low-e coated insulated glass on a hot day and then to measure the temperature of the outside pane.  The difference would be easily observed.

The use of energy efficient windows will result in reduced cooling expenses, provide greater comfort for building occupants, and also aid in noise reduction. 

Safety Glazing
Many western building codes mandate the use of safety glazing in interior and exterior doors and in tub and shower enclosures as well as other locations identified as hazardous.  The primary purpose of safety glazing is to reduce the potential of injury. 

Fully tempered glass and laminate glass are types of safety glazing.   A common danger is of a person walking into a glass door.  Annealed glass breaks into large sharp pieces which can result in serious injury whereas fully tempered glass will fracture into small dice like pieces greatly reducing the likelihood of serious cutting or piercing injuries which can occur from large pieces of broken annealed glass. 

In addition to the break pattern, fully tempered glass is nearly 4 times stronger than annealed glass further reducing the likely hood of breakage at impact.

Laminated Glass consists of 2 or more pieces of glass that are bonded together with a PVB interlayer or other resin/urethane/polycarbonate interlayers, etc.  The pvb interlayer supports and holds the glass when broken or cracked.  Thus, the likelihood of injury via cutting or piercing injuries is significantly reduced when compared to annealed glass.
