The MHD Clar­i­on Series apart­ment win­dows com­bine out­stand­ing crafts­man­ship with a tra­di­tion­al look and feel out­stand­ing crafts­man­ship with a tra­di­tion­al look and feel. Strong and ener­gy effi­cient, the Clar­i­on Series is suit­able for gar­den style or mid-rise apart­ments, mul­ti­fam­i­ly homes, as well as his­toric restorations.

The low­er the I‑value, the greater a window’s resis­tance to heat flow and the bet­ter its insu­lat­ing val­ue. Please check the Nation­al Fen­es­tra­tion Rat­ing Coun­cil (NFRC) at www.NFRC.org to com­pare ener­gy per­for­mance values.

Design Pres­sure (DP) — Spec­i­fies a win­dow’s resis­tance to wind and oth­er dynam­ic pres­sures. The lighter the DP rat­ing, the stronger the window.
Air Infil­tra­tion (CAM/FT2) — The amount of air in cubic feet per minute that may come through the win­dow at speeds of 25MPH.
Water Pen­e­tra­tion (mph) — Spec­i­fies wind load pres­sure in mph a win­dow can with­stand with­out leak­ing, under rain equiv­a­lent to 8″ per hour.
Struc­tur­al Integri­ty (mph) — Wind load in mph the win­dow can with­stand before breaking.

All result num­bers are based on test­ed win­dow sam­ple by NFRC and AAMA test­ing win­dow guide­lines. Use for com­par­i­son pur­pos­es only. Actu­al val­ues may vary depend­ing on instal­la­tion, size of the win­dow, and oth­er con­di­tions. All illus­tra­tions, pho­tographs, and spec­i­fi­ca­tions are based on the lat­est prod­uct infor­ma­tion avail­able at the time of pub­lish­ing. Some win­dows shown with option­al fea­tures. See the actu­al prod­uct for com­plete accu­ra­cy. The man­u­fac­tur­er reserves the right to alter or dis­con­tin­ues any mod­el or spec­i­fi­ca­tion with­out notice.
