Sandwich-construction polystyrene insulated sectional commercial doors. Mid-tier insulation at a lower price than polyurethane Intellicore — the right choice for service shops, partially-conditioned warehouses, and budget-conscious commercial use.
Polystyrene-insulated commercial sectional doors are the mid-tier insulated commercial choice — sandwich construction with polystyrene foam core between two steel skins. Less thermal performance than polyurethane Intellicore, but at a noticeably lower price. The right choice when some insulation matters but maximum R-value isn't critical.
Auto service shops where the bays are heated but not climate-controlled. Partially-conditioned warehouses. Industrial spaces where some thermal performance matters but the budget doesn't justify polyurethane Intellicore. Cost-conscious commercial replacement projects where the existing door is uninsulated and the upgrade target is reasonable thermal performance, not maximum.
Sandwich construction: outer steel skin, polystyrene foam board core, inner steel skin (or vinyl back panel for cost reduction). Section thickness typically 1⅜ to 2 inches. Steel skins in commercial gauges with paint finishes in standard white and brown.
The polystyrene foam doesn't bond to the steel skins the way polyurethane does — it sits in the cavity. This is what makes the door cheaper to manufacture, but it's also what allows some thermal bridging at the section frame. R-values run 6 to 9 typically — adequate for many commercial use cases.
If the building behind the door is fully climate-controlled (food storage, pharmaceuticals, conditioned manufacturing), polyurethane Intellicore's higher R-value and lack of thermal bridging usually pay back in lower heating costs. If the space is partially conditioned or the budget is tight, polystyrene is the practical choice.
Polystyrene insulated commercial sectional pricing varies with size, steel gauge, finish, and operator. Below are typical Hudson Valley ranges.
Reynolds installs polystyrene insulated commercial doors across auto service shops, partially-conditioned warehouses, and budget-conscious commercial replacements throughout the Hudson Valley and Fairfield County. We'll help you decide between polystyrene and polyurethane based on your conditioned-space and budget requirements.

Typically R-6 to R-9 depending on section thickness and skin construction. Lower than polyurethane Intellicore (which runs R-12 to R-20.4), but adequate for many partially-conditioned commercial spaces.
Polystyrene insulation is sandwiched foam board — manufactured separately and inserted between the door skins. Polyurethane is foam-in-place — injected during manufacturing and expanded to fill the cavity. The foam-in-place process is more expensive but produces higher R-values and eliminates thermal bridging.
Yes — standard finishes are white and brown, with custom paint matching available. Reynolds discusses finish options at spec.
LiftMaster Logic 5.0 commercial operators are standard. Heavy-duty and high-cycle hardware kits are available for service-shop applications that open and close the door many times per day.

"My garage door would not open so I called the number on a sticker next to the garage opener. It was after hours so I left my info and got a call back first thing in the morning. Within 30 mins I had a working garage door. They were amazingly nice as well as efficient."
