Centor Integrated Doors are tested to ensure they can withstand every season, climate and time of day so they can be specified with confidence.

Air, Water and Structural

Centor Integrated Folding Doors achieved the following performance levels when tested in accordance with the standards set by NFRC/AAMA/WDMA/CSA.

US Air Infiltration 0.16 cfm/ft2
Canadian Air Infiltration/Exfiltration A2 (0.12 cfm/ft2 In, 0.14 cfm/ft2 Ex)
Water Infiltration 5.43 psf /260 Pa (DP 35)
Design Pressure DP45

The Design Pressure (DP) rating represents the maximum positive and negative wind load that a window or door can experience without breaking, deglazing or permanently distorting. The DP Rating is expressed as a positive and negative pound per square foot measurement (+/- psf). The Centor Integrated Folding Door was tested to a structural load of 67.67 psf and achieved a DP + /- 45 psf rating. The Centor Integrated Folding Door was tested in accordance to AAMA/WDMA/CSA 101/I.S2/A440-08,-11.

Florida hurricane approval

The Centor 205 and 405 Integrated Folding Doors and 211 XO Integrated Sliding Door are approved by the Florida DBPR for use in coastal zones. They are all built to withstand coastal conditions such as fluctuating temperatures, burning sunshine, salt and wind.


Centor Integrated Doors are rated to a 0.23 Btu/h ft²-°F U-factor when triple-glazed. Even more impressive, the doors that include an integrated shade built into the doorframe, was awarded a 0.19 Btu/h ft²-°F U-factor when the shade was drawn.

The National Fenestration Rating Council (NFRC) has developed and governs a national rating system for thermal performance of fenestration products. The Centor Integrated Folding Door was tested in accordance with NFRC 102-2010.
