Access Doors

With energy conservation at the heart of every design more and more ductwork systems are required to be pressure tested to ensure they meet leakage parameters in accordance with DW143 and EN 15727:2010.

At the same time, the revised DW144:2016 has called up additional cleaning and inspection doors be provided for a wide variety of applications. Increasing the number of access doors in all ventilation ductwork has often resulted in failing to meet the leakage rates due to the use of such high quantities of untested access doors.

AMS have sought to remedy this issue by assembling a complete range of doors to suit every duct type, size and shape in providing the right door for the right application. Included in this range are insulated/ uninsulated, fire rated/ standard, round/ square, tabbed/ plain, and, most importantly, tested/ untested doors.

Our comprehensive range of access doors includes:



  1. SureFire EnSave Heavy-duty Fire Rated Doors (BSRIA Tested)
  2. SF/AD SureFire Standard Fire Rated Doors
  3. EnSave 144 Tested Doors Suitable for DW143 Leakage Rates
  4. ECO/RD Uninsulated (rectangular) and ECO/R/RD Uninsulated (round)
  5. EZFIT/AD Insulated Tabbed Doors (for DW144 Ductwork)
