The following pages have general information on heat forming AZEK Trim and Moulding Products using a heat blanket and are not intended as a Users Manual. You should always use the heat blanket manufacturers User Manual instructions when using their product.

�� 2 x 6 Boards 8” Long

�� Cement Boards �� One at 10” x 65” �� One at 5” x 65”

heat Preparing to Heat Form

�� Layout wooden blocks to support cement board (8” x 65”) and to protect work surface from heat

�� Place heat blankets on Cement board

�� Begin preheating �� Place 5” x 65” cement board between blankets �� Set Controller to High �� Preheat for 15-20 Min

�� Preheating system �� Do not allow heated portion of blankets to come in direct contact �� Temperature should reach about 290 -300 degrees F �� Lower heat if forming will not begin for some time

�� Place AZEK material (3/4”x 3.5”x 64”) between blankets with preheated cement board on top and bottom as shown

�� Continue heating for 7 – 10 minutes temperature should reach about 300 F �� Periodically check temperature

�� When product is approaching final temperature check for consistency �� Consistency should be like cooked spaghetti

�� When proper temperature is reached place material over center of form �� Gently form material around radius �� If product wrinkles or feels too rigid to form straighten piece out before it cools too much and place back in heat blankets. �� If top edge wants to roll away or curl from form; a block of wood can be used to gently hold material flat while it cools. Too much pressure will mark the AZEK surface.

�� Clamp Product and allow to cool �� Product can be removed once cool enough to maintain its shape

�� Longer pieces of AZEK can be heat formed by heating one side at a time. �� Lay blankets end to end without overlapping blankets �� Begin heating product one side at a time. Flip product periodically until board reaches proper temperature. �� A piece of preheated cement board can be used to keep top face warm during the heating process. �� A tight radius may have a tendency to wrinkle slightly on the inside edge of the formed piece. A router can be used to clean this edge up. �� Wrinkling on larger radius pieces may be an indication that the part has not been heated enough or that it has cooled too quickly

�� Heat Blankets are available through your AZEK Building Products Dealer �� Or direct from Heatcon- AZEK Trim Heat Forming Kit HC99-100 Phone: 800-566-1990 Email:
