Garage Door Construction
Quality construction, whether comfort or budget comes first.
Find the right insulation for your garage
You don’t need the highest R-value for every garage. The right choice depends on where your garage is, how you use it and how much temperature control matters to you.
3-Layer Polyurethane: R‐12 or R‐16
Best for maximum comfort and performance
A great choice for attached, heated or cooled garages, workshops, home gyms and spaces you use year-round.
Polyurethane delivers our highest insulation levels, along with excellent sound reduction and added structural strength.
Construction: 2 steel skins + high-pressure injected polyurethane foam
Best for: Attached / conditioned spaces
3-Layer Polystyrene: R‐7 to R‐15.1
A strong balance of comfort, durability and value
A versatile choice for garages where comfort and durability matter.
Polystyrene helps control temperature and noise, while 2 steel skins add rigidity and a clean, finished interior.
Construction: 2 steel skins + polystyrene insulation
Best for: Everyday comfort
2-Layer Polystyrene: R‐7.2
Smart insulation at a practical price
A smart choice when some temperature control makes sense, but maximum insulation doesn’t. Polystyrene adds comfort without paying for performance your garage may not need.
Construction: 1 steel skin + polystyrene insulation + protective backing
Best for: Basic insulation
1-Layer Non‐Insulated
Best for unheated spaces and tighter budgets
Ideal for detached garages, sheds and other unheated spaces where temperature control isn’t a priority. A solid steel Garaga door without the added cost of insulation you don’t need.
Construction: 1 steel skin, non-insulated
Best for: Unheated detached spaces
What goes into a garage door built to last?
Built to keep the elements outside
Tight-fitting joints and flexible weather seals help keep drafts, rain and outside air where they belong. Outside.
Polystyrene & Non-Insulated Doors
Tongue-and-groove joints fit sections closely together, while flexible U-shaped bottom weatherstripping helps seal along the floor.
Even More Protection with Polyurethane
Our polyurethane-insulated doors add Garaga InterLokTM joints, wood end blocks and U-shaped bottom seal flexible up to -24°F to further reduce heat transfer and help keep the elements outside.
