It’s Smart to Know About Garage Door Insulation

garage door

When you consider that the garage door is the largest opening in your home, it just makes sense that you would want to make sure that it is as well insulated as possible.

I discovered this myself last winter when the thermostat reached minus 5 degrees outside.  I like most folks; I do my do-it-yourself projects in my garage.  I’m lucky enough to have an electric heater in my garage (after many years of using a kerosene heater/and several years of suffering from those fumes) that allows me to work in the garage on even the coldest days.

However, while working last winter I realized the heater was running non stop.  I finally realized that the reason it was running constantly was my old wooden garage door.  I went outside in the evening and I was able to see light coming through the cracks between the panels of the door, when I placed my hands on the panels they were warm to the touch.  All the heat I was producing in my garage was escaping through the panels of my non-insulated garage door.

That is when I started re-searching garage doors to replace my old wooden door.  I found a company that Shari and I have been proud to not only call one of our sponsors, but a company that I have decided to use for my own home: Haas Door.

I have installed the American Tradition Model on my home and not only is it fully insulated with polyurethane foam construction is has the following features.

American Tradition Series

  • sectionalVinyl top cap provides thermal barrier and foam protector.
  • Full thermal break on ALL sections insulates from extreme temperatures.
  • Embossed galvanized steel skins assure protection from warping, rotting, and rusting.
  • Attractive deep wood grain embossed steel is factory pre-finished and painted on both the exterior and interior with epoxy primer and polyester finish coat.
  • Rigid vinyl end caps protect and seal the foam core and provide a smooth surface for door stops.
  • 1 3/8” polyurethane insulation is pressure injected and leaves no voids when bonding to both exterior and interior skins.
  • Heavy 20-gauge galvanized back-up plates extending the full height of each section give superior hardware support.
  • Flexible vinyl bottom astragal fits contour of floor providing a weather seal and is easily replaced if damaged.

When purchasing a garage door for your own home, keep in mind the following information to help you make an educated decision on your garage door purchase.

When comparing products prior to specifying or purchasing a sectional door it can be confusing when faced with all the different choices. There are many different styles and designs available. One of the common choices that the consumer is faced with is the material used to insulate the door sections.
 
It is only natural for a manufacturer to promote their product materials and design. For this reason we would like to present some facts that sometimes get overlooked.
 
With today’s concerns over rising energy costs, your choice of a garage door becomes a major decision. For this reason Haas Door Company is proud to be a supplier of superior, high quality door sections. A Haas Garage door will provide the best performance for your dollar!

Insulating Materials:

Two common insulation materials used in garage doors are polyurethane and polystyrene. Polyurethane and polystyrene both have some distinct advantages and some disadvantages. Both materials are commonly misrepresented and misunderstood.

Polyurethane Foam Construction:

Polyurethane foams are used as insulation in garage door panels, roof insulation on commercial buildings, wall insulation in newer high efficiency homes, office chairs, refrigerators, freezers, walk in coolers, furniture and in automobiles for dashboards, armrest’s, suspension bushings and many other areas.

Polyurethane foam is a two-part system. It begins with two chemical blends that when mixed together expand and cure to fill the garage door panel. During the expansion, the foam flows and completely fills the inside of the panel and comes in complete contact with and becomes fully adhered to the steel skins of the garage door panel to form a composite structure that is of exceptional strength and rigidity.

Polyurethane foams are very stable when encapsulated (fully enclosed) inside a garage door section.

The polyurethane foam in a Haas garage door section is fully enclosed inside the steel skins and therefore protected from R-Value loss! This design puts the insulation properties of polyurethane foam way ahead of polystyrene foam for performance and value!

Polystyrene Foam Construction:

Polystyrene foam board is used as insulation in garage door panels, houses, as vapor barriers, and most commonly as an inexpensive packing material.

Polystyrene foam board must be attached to or inserted into the door sections. The foam must be held in place by mechanical means or by bonding the foam to the door skins by using adhesives (glue).

Insulation Testing:

The factors that effect the insulation properties of a garage door depend on the materials used, design of the sections and the air gaps (leaks) between the section joints and the doorjambs. Inch for inch polyurethane foams surpass polystyrene foams when it comes to insulation values.

The publication of R-Values is sometimes listed as the R-Values of the insulation only, sometimes referred to as “core value”. The insulation property of the installed door is the only true representation of the doors performance.

Thermal performance testing is performed using established test methods. Independent laboratories usually perform these tests. The test performed duplicates the normal installation conditions of a 10’-0” x 10’-0” Haas garage door.

The 10’-0” x 10’-0” doors were independently tested by Architectural Testing, Inc., York, PA. See chart below.

Insulating with Polyurethane provides a superior product with higher insulation properties and a stronger unitized section.

When comparing garage doors ask to see the ANSI/NAGDM 105-1992 test results for installed doors.  See chart above.

So when you are considering replacing or installing a garage door, make sure you do your research regarding the insulation properties of the door.  The best place to do your research and to see a wide selection of garage doors, make sure to visit an authorized garage door dealer in your area.  For a Haas Door dealer in your area, visit  haasdoor.com/locator/index.php

Good luck with your garage door search and have a great time working in your warm and toasty garage.
