  • Q What is your payment terms ?

    A 50% deposit by T/T advance and 50% balance by T/T before loading; L/C is accepted as well.
  • Q What is Autoclaved Aerated Concrete?

    A Autoclaved Aerated Concrete (AAC) is a lightweight concrete that is formed into blocks and panels for a wide range of loadbearing and non-loadbearing construction applications. It is manufactured from silica sand, cement, recycled material, lime, gypsum, aluminium paste and aerating agents. It is moulded, cut and steam pressure cured in an autoclave before being packed, ready for transport.
  • Q Is Autoclaved Aerated Concrete a new building material?

    A Aerated Concrete Autoclaved (AAC) is an amazingly innovative building material that has been used in Europe for more than 80 years and in the US for more than 15 years.  
  • Q Where has Autoclaved Aerated Concrete been used?

    A It can be used ranging from low rise industrial/commercial developments to high rise offices or medium density residential buildings. 
  • Q Is Autoclaved Aerated Concrete a load bearing material?

    A The intensity of pressure for cube is more than 4mpa. The load bearing capacity for one point is more than 1200N. The rebars within AAC panels are made according to computer calculating force. As a non-loadbearing cladding, AAC panels can be used under circumstances of pressure.
  • Q What are the benefits of Autoclaved Aerated Concrete over other building materials?

    a. Cost effective - lightweight panels allow for reduced structural components and smaller lifting equipment.
    b. Excellent thermal resistance performance.
    c. Acoustic performance - effective sound transmission barrier between external and internal environments of the building.
    d. Excellent fire rating properties.
    e. No wet trades - less mess and a cleaner, safer work area.
    f. Less wastage - significantly reduced waste as panels can be custom-made to length requirements.
    g. Fewer waste bins and less crane movements.h. Design flexibility - panels can be easily cut and routed to suit design requirements.
    i. Panel lengths up to 4.8 metres. 
    j. Strong, secure and durable with corrosion protected steel-reinforced panels.
  • Q Can I cut a window or door opening into the Ecotrend wall?

    A In most cases it is possible to retro-fit an opening into Ecotrend walls. Professional advice must be sought to ensure the structural framing is suitable for this modification.
  • Q How do I attach other external items to our Ecotrend walls?

    A A fixing guide is provided to assist you in selecting the appropriate fixing method for the object you are to secure to the walls.
  • Q How do I drill penetrations into the Ecotrend for such things as external lights or speakers?

    A Holes can be drilled in Ecotrend walls using a masonry drill bit fitted to a standard (not rotary hammer) drill. Once the penetration has been filled with the required cables or the like, the gap around the penetration should be filled with a reputable flexible sealant such as Sikaflex polyurethane sealant.
  • Q How long will the coating system last?

    A Ecotrend coating systems are permanent. Like all surfaces exposed to the elements, preventative maintenance will keep it looking its best and preserve its optimum performance.
  • Q Will I ever need to recoat?

    A Ultimate life-cycle costs of the total facade and finish are optimised when an Acrylic paint membrane (min DFT 150 micron) is applied every 10 years. This ensures the integrity of the weather proofing system and provides the opportunity to address typical longer term building maintenance issues - such as building movement. Preserving your investment in Ecotrend is just one good reason, secondly a “10 year refresh” maintains the property’s visual impact “as new” and adds to the resale value if, and when, the time comes to sell.
