Maximum thermal performance. Minimum noise. Built in America. Haas's Insulated Steel series delivers the highest R-values in their residential lineup — the smart choice for any attached garage in Southeast Missouri.
If your garage is attached to your home — sharing a wall with your living space, laundry room, kitchen, or bedroom — the thermal performance of your garage door has a direct and measurable impact on your home's energy efficiency and your comfort. An uninsulated or poorly insulated garage door is one of the largest sources of heat loss in winter and heat gain in summer for attached garages.
Haas's Insulated Steel series addresses this directly with a triple-layer sandwich construction that uses injected polyurethane foam as the core material. Unlike competitors who simply insert a polystyrene board between two steel skins, Haas injects the foam in a liquid state and allows it to cure bonded to both steel faces. The result is a structurally superior, thermally efficient, dramatically quieter door that outperforms insert-foam doors across every measurable metric.
Mastertech recommends the Haas Insulated Steel series as the first choice for any homeowner in Southeast Missouri with an attached garage — and the best overall value in their lineup when long-term energy savings and comfort are factored into the cost equation.
The foam bonds permanently to both steel skins — the door acts as one rigid unit, not three separate layers. This eliminates flex, oil-canning noise, and delamination over time.
Polyurethane foam provides approximately twice the R-value per inch of polystyrene. Haas achieves up to R-19 in their thickest Insulated Steel configuration.
A bonded polyurethane core absorbs vibration and sound significantly better than a loose polystyrene insert, making the door measurably quieter during operation.
The bonded construction creates a panel that resists denting and flexing under wind load and impact far better than single-layer or polystyrene-insert doors.
Haas's standard insulated model. 1-3/8" total door thickness with injected polyurethane core. R-value of approximately R-12 to R-14 depending on configuration. Excellent for most attached garage applications and the most popular Haas Insulated Steel model Mastertech installs.
Maximum insulation in the Haas residential lineup. 2" total door thickness with the thickest polyurethane core available, achieving R-values up to R-19. The right choice for heated garages, home workshops, garages with bedrooms directly above, and homeowners in the coldest microclimates in Southeast Missouri.
The Insulated Steel series is available in raised-panel and flush profiles consistent with the American Tradition design language — which means you don't have to sacrifice style for thermal performance. Available in the full Haas color palette including painted solid colors, woodgrain embossed finishes, and optional window insert configurations in multiple glass types.
Homeowners in Farmington and throughout Southeast Missouri experience significant temperature swings — summer highs above 90°F and winter lows well below freezing are the norm. An attached garage with a high-performance insulated door stays significantly more temperature-stable year-round, reducing the HVAC load on the adjacent living spaces. Most homeowners who upgrade from a non-insulated to a Haas Insulated Steel door notice a meaningful difference in comfort and energy costs within the first season.
Beyond energy savings, the reduced noise from a properly insulated door is one of the most immediately appreciated benefits — particularly for homeowners whose garage shares a wall with a bedroom or home office.
