How tough is your garage door?
Not as strong as you might think, if it includes thermal breaks.
Thermal breaks are long on hype, but short on performance----especially in a garage door, which is often seven times wider than an entry door. A thermally broken door is a door waiting to be broken.
Thermal breaks do more to compromise a garage door, than they do to ensure a sustained R value for energy efficiency. In essence, the push for greater R value often compromises the strength of the garage door.
The marketing of these compromises is often intriguing. One manufacturer boasts it uses wood blocks to ensure thermal breaks for hinges holding sections together, noting the wood gives them more fastening leverage than other companies.
Wood cracks, warps and rots easily, so any sustained value of the extra fastening, would be easily compromised. Many companies use a mild steel self-fastening screw which is used to fasten the hinge to the section. Those are often short and don't adjust to jarring use well.
The anatomy of a strong garage door goes beyond thermal breaks, to include injected foam insulation in many doors on the market today.
Utilizing injected foam, sandwich garage doors are shaped by the insulation. The injected foam often translates to a higher R value initially. But it too comes with big compromises.
Foam breaks down quickly and easily. The constant jarring, twisting and flexing of a garage door moving up and down shifts the insulation within the panel, causing the door to lose its shape. So the result is diminished R value and an ugly delaminating garage door.
Martin Garage Doors has designed its door differently than other manufacturers.
A Martin Garage Door features a full wrap around flange. The heavy-duty style hinge features a custom-designed dimple, which helps ensure a lifetime connection when the professional installer fastens the hardened thread forming screw. The screw actually binds the hinge, stile, and door section into one solid unit. In essence there is a binding of steel to steel.
There is more durability in binding steel to steel, than in trying to hold something together by plastic, rubber, foam or glue.
The insulation in series II Martin Garage Doors is contained with heavy-duty multi-contact steel stiles, with a continuous sheet of a textured, galvanized steel back-skin. The Martin raised panel door's steel face is not laminated to the insulation.
In essence, Martin's hardened steel fasteners hold up to four layers of steel together.
The durability with which the door is held together manifests itself over time. A dent is repairable even on an insulated Martin Garage Door. The insulation is recyclable, removable or reusable and the R values of the door remain the same over a longer period of time than other doors.
Martin binds steel to steel with its garage doors, rather than trying to hold something together by plastic, rubber, foam, wood or glue.
