Every glasser knows that the more floor racks you have the more production you can achieve. Epoxy takes longer to set than polyester and slows down traditional glass shops. Boards in the hot coat phase take longer to stop dripping at the rail so that they can be placed on a wall rack or flip over to brush out the other side. These customizable sized rooms speed up this process , significantly (especially in winter months) and at significantly reduced energy costs. They are able to be thermostatically controlled and can maintain a regulated temperature (R19 insulation value). Optimum temperature during epoxy wet-layup times is 77-80 degrees F at sea level (25-26 C). The room can be ramped up to 140-150 F after the resin has set or reached gel state for a quicker cure and a legitimate post-cure. Ramping up temps during the wet phase results in a poor lamination that has drained and/or caused pin-air. The better you can regulate temperature, and the more boards you can speed up the final cure process all at once, the faster your production rates will be.
