Pella single-, simulated-, and double-hung windows are traditional in every detail – with all the Pella innovations you demand. Our quality select wood is treated with Pella’s exclusive EnduraGuard®. This triple-action formula has three active fungicides that have a broadbase of protection against moisture, stains and decay caused by mold and mildew, as well as termite damage. The exterior of the wood windows are protected by Pella’s low-maintenance EnduraClad®, or EnduraClad® Plus, aluminum cladding system. Upper and lower sash are fully operable on double-hung and balanced to open to virtually any position. Both sash tilt to the interior without removal for easy cleaning of outside glass. Sash corners are joined three ways (mortise and tenon, adhesive, and metal fasteners) for increased strength. Sash locks are factory installed. Our wide range of glazing options includes custom glazing and obscure glass. Pella maintains its high standards by taking the time to test virtually every vent unit for air infiltration, so you know you’re getting a quality product.
