[wpex more = “CLICK TO SHOW MORE” less = “CLICK TO SHOW LESS“]Sing Core provides Sing panels with window and door pre-cut and ready for installation. We will cut 1/8 larger in width and 3/16 inch wider in length to fit your window glass. We build a frame using 1.25 inch solid wood to your specifications. You may create any size or shape of window or door with our simple method just by providing a simple drawing.[/wpex]


[wpex more = “CLICK TO SHOW MORE” less = “CLICK TO SHOW LESS“]Sing Core windows and doors are profile ready for CNC routing. You may add molding or trim to create your own window or door design, otherwise we will provide you with thicker skin — such as 1/4 inch or thicker mdf, hardboard, etc. — for you to carve or profile by CNC machine. With Sing Core windows and doors you can create a true raised-panel door or any design you desire.[/wpex]


[wpex more = “CLICK TO SHOW MORE” less = “CLICK TO SHOW LESS“]The standard ready-to-ship panel condition is, “untrimmed.” This leaves unfinished exterior edges that may have exposed adhesive and might require being built ½ inch over-sized for trimming at your location. An additional fee will be assessed for trimming and sizing in our factory. All trimmed edges are 1/2 inch over width and 1/2 inch over length. After trimming, your Sing Panel will be 1/2 inch less (4 x 8 will be 47.5 inch x 95.5 inch). Standard solid wood edging with 1.5 inch will be reduced to 1.25 inch after trimming.[/wpex]
