  Garage Door Insulation is a MUST HAVE for any un-insulated metal garage door, especially those facing the morning EAST sun, afternoon WEST sun or any door that needs to retain heat in the winter and keep cool in the summer!  Garages are typically the largest un-insulated area of a home and the garage door is a natural choice to insulate.  Join in combating the rise in high energy costs by installing our Garage Door Insulation and Threshold Seals which will provide a simple, cost effective solution and return on your investment.  Garage Door Insulation will decrease your heating and cooling costs by providing up to an "R4.6" insulation value with our "PanelFoam™" EPS (UL® certified Expanded PolyStyrene) kits, and up to a "R6.0" insulation value with our "Reflective Double Foil" kits when installed properly on your garage door.  Insulating your garage door will keep your garage cooler in the summer and warmer in the winter, but also reduces street noise and those squeaky opening and closing sounds by providing an additional sound barrier.  Our Garage Door Insulation Kits can be professionally installed within our service areas or installed by the homeowner by following the enclosed instructions with a tape measure, straight edge and utility knife!

  Our Garage Door Insulation Kits and Door Seals carry a One Year Limited Warranty from date of purchase.  Our Garage Door Threshold Seals carry a Lifetime Warranty from date of purchase.

Reflective Foil Garage Door Insulation

Recent customer comments:

"We received our order and I have installed the insulation.  The afternoon sun hits the garage door for a good four hours and it was unbearable.  After installing the insulation we really felt the difference.  The insulation reduced the temperature by (my guess) of 15 to 20 degrees.  The garage is now usable where before it was not.  Thank you for a wonderful product."  E. Doss, TX

"I just wanted to let you know that I received the order and already have it installed on the door.  Installation went smooth as silk and it looks great!  Thanks again for the quick shipment, was a pleasure doing business with you."  W. Hendrickson, MD

Reflective Foil Installation Instructions

(Detailed instructions are included with each kit.)

1. Since you are taking the time and effort to install a cost effective insulation product for your garage door, why not take the time to do a little maintenance on your garage door that may be over due?  Click here to see our maintenance suggestions.

2. Tools Required: Utility Knife (included in kit), Adjustable wrench to remove door obstructions like handles or locking mechanisms, Spray Cleaner like Windex/409 and wiping rags.

3. Clean all exposed metal edges and surfaces of the door to be taped.  We normally use Windex and sometimes 409 if there is oil/grease present.  Make sure all dust, dirt and oil is completely cleaned off of the exposed metal surfaces before applying the double-sided tape.  Also, do not apply tape to a door that is wet or in high humidity situations that will cause the tape to not properly adhere to the door or to the foil.  Sometimes new doors have a thin film of oil on the galvanized parts, and there is sometimes over spray of lubricant of the hinges on the door, make sure to completely clean the oil off, the tape will not stick to the door if there is oil and this will void any warranty or returns!

4. Once the door panel edges are clean, measure, cut and apply double sided tape (included in kit) and press firmly onto all exposed edges of the garage door for the reflective foil to attach to.  Apply tape when temperatures are above 45°F.

5. Before applying the Reflective Foil to the double sided tape, make sure the foil is clean from dust, dirt, greasy finger prints and anything else that will interfere with proper bonding to the double-side tape.  DO NOT LAY THE FOIL ON THE GARAGE FLOOR, CONTAMINANTS MAY GET ON THE FOIL AND PREVENT PROPER BONDING!  Clean the Reflective Foil with Windex if needed.

6. Remove double sided tape strip and attach reflective foil to the outside frame edges of the garage door panels by pressing insulation firmly onto panel edges and install one horizontal row at a time.  Trim excess reflective foil as required.  Now enjoy your quieter more comfortable garage!

7. Do not paint the Reflective Foil, aluminum will not reflect if painted.

There's a Wrong Way and a Right Way

  Texas Garages believes in offering our customers Quality Products at Reasonable Prices and support after the sale, but it doesn't stop there.  We are a real company with real locations in Austin and Dallas-Fort Worth, we don't work out of our house and we don't sell our products on eBay.

  We also want to inform you of the WRONG WAY and RIGHT WAY to purchase and install Reflective Foil Insulation for your Garage Door.  The pictures below show the WRONG WAY and RIGHT WAY to install Reflective Foil Insulation on your Garage Door!  You can find companies on the Internet that sell pre-cut foil panel kits and claim R-Values from 10 to 16, but be careful.

  First let's review the installation.  The foil panels in the WRONG WAY Picture are attached to the door skin directly, reducing overall "R" value because of not providing an "Air Pocket" between the foil and the door skin.  The Air Pocket acts as an additional radiant barrier and increases the overall effectiveness and performance of your garage door insulation installation.  Another major error is the panels do not cover the vertical support rails and side frames of the door allowing passive heat and cold to pass through the door into the garage from the exposed metal.  By installing the foil on the "entire" door and covering as much exposed metal as possible provides the best insulation performance.

  Now "R" values, these mystical insulation property values are determined by 3rd party engineering certification laboratories.  Anyone can claim any "R" value they want, but ask them if they have independent testing data to support it.  "R" values are rated several ways on the same product, for instance "Horizontal" thermal penetration which is usually a ceiling or attic application where the material is laying horizontally for upward and downward usage.  Horizontal thermal penetration is always the highest "R" value, and some companies use this value to rate their garage door insulation and this would be incorrect because garage doors should be rated using a "Vertical" thermal penetration rating, meaning a wall or door insulation application, which will always be lower than horizontal.  For instance our Reflective Foil product is rated at R14.3 Horizontal Resistance and R6 Vertical Resistance, so we use the R6 not R14.3 rating which is more appropriate for Garage Door Applications.  Our products have been tested, certified and the datasheet is downloadable below.

Installation Instructions

Provides Up to R4.7 Insulation Value

1.    Question:  "Does the PanelFoam come with plastic caps or ends on the material to give it a finished look, like a picture frame?"

 

Answer:  No.  The PanelFoam Panels on one side have Expanded Polystyrene (EPS) that goes next to the garage door and the other side has a High Impact PolyStyrene (HIPS) laminated plastic facer for durability and easy cleaning.

2.    Question:  "How do you attach the PanelFoam to the garage door, does it have double-sided tape or glue?"

     

Answer:  The PanelFoam Panels "tuck" between the recessed vertical garage door rails and hold themselves in.  No tape, glue or screws are needed.

 

3.    Question:  "Would you recommend using both the PanelFoam and Reflective Foil to get the best insulation value?"

       

Answer:  It is not recommended to install both types of insulation products on your door.  The reflective foil kit needs a minimum air space of ¾” between it and the door so you wouldn’t be able to do that by attaching it to the PanelFoam.  Also, by installing both products with R6 and R4.7 will not give you a total insulation value of R10.7.  You only get the highest insulation value of the highest R-value product installed, which in this case would be up to a R6.

 

4.    Question:  I have wooden doors, will either the Reflective Foil or PanelFoam kits work on my doors?

 

Answer:  Maybe.  If you have standard metal doors and the wood fascia was attached to the exterior of the door, then either kit will work.  If your doors are truly all wooden the answer is no.  Our kits are designed for standard aluminum/metal doors.

 

5.    Question:  I have metal hurricane doors, will either kit work on these type doors?

 

Answer:  Yes, however, most new style hurricane metal doors have smaller panel heights, usually 16"H instead of the standard 20"H and they are heavily braced with both vertical and horizontal bracing.  The bottom line is that you can install either kit on these types of doors, it will just be a more involved process to both trim the insulation and gain access to the panels. 

 

NOTE:  Do not take off all the braces at once, only take off one brace at a time, install the insulation and put the brace back on before moving to the next brace.  By taking off too many braces at once you run the risk of getting your door out of alignment.

 

6.    Question:  I have a new home and my garage gets extremely hot in the afternoons, almost unbearable.  I have standard garage doors that face the west and get direct afternoon sunlight.  Also, the attic above the garage ceiling was not blown with insulation, is the heat problem more a function of the non-blown ceiling or heat through the garage door?

 

Answer:  Both the garage door and attic not being insulated are contributing to your heat gain.  The garage door is the easiest, quickest and least expensive to insulate and you can begin to notice an immediate difference.  Once your door is insulated you should then contact an insulation expert/company and discuss your attic options.

 

7.    Question:  Will the additional weight of either insulation kit effect the operation of my garage door opener?

 

Answer:  No.  We have installed hundreds of these kits and have never experienced any garage door opener problems.  If you happen to experience this problem, most garage door openers have torque setting adjustments that can be made.  Check your owners manual or consult a professional Garage Door Specialist.

 

8.    Question:  I have a roll up door on the storage unit I rent that faces the afternoon West sun and it gets extremely hot.  Is there a product I can use on that type of door?

 

Answer:  Not that we have found.  Because this type of door "rolls up into itself" the PanelFoam is not flexible enough nor is there a way to attach it.  The Reflective Foil doesn't have an air pocket thus reducing your "R" value, plus the door won't properly roll up with the material on the door.

 

9.    Question:  Installing the Reflective Foil, am I supposed to stick the insulation to the door frame and to the back edge of the door that folds up, leaving an air gap between the insulation and the garage door?  If so, how do I keep the middle of the insulation on each panel from sagging over time?  Or should I cut the insulation into (16) individual panels and attach it directly to the garage door, leaving no gap between the door and the insulation?

 

Answer:  You will usually have (4) horizontal rows of panels on your garage door, treat each row separately. Clean all the outside exposed metal edges where you will be placing the double-sided tape, remember, failure to clean the door adequately will not allow the tape to bond properly.  After you apply the tape, start at one end of a horizontal roll and using the bottom edge of your horizontal roll as a guide, unroll your reflective foil roll slowly and carefully making sure it attaches to the tape firmly. Your panels are approximately 20” high and the foil rolls are 24” high, so once the entire horizontal roll is done, go back and trim the height of the roll and around hinges, locks, etc.  Be careful not to trim too much, key items to remember are trying to create an air tight space between the foil and the door skin and cover as much exposed metal with the foil as possible so heat/cold doesn’t radiate into the garage. The middle of the insulation will not sag because it is attached on all four edges as you can see in our installation pictures above.  Do not attach the foil directly to the door skin because you won’t have an air pocket, if you do this you will decrease your “R” value by 50%.  Also, do not cut individual panels, by rolling out an entire horizontal roll the installation is much easier and more effective.

 

10.    Question:  I purchased the optional roll of White Seam Tape for the Single Foil White Vinyl Garage Door Insulation Kit.  Is this tape used to cover the horizontal gaps between the garage doors rows of panels?  I am not sure if that will cause a problem when the door opens?

 

Answer:  The White Seam Tape is intended to be used to repair damaged areas to the foil rolls or to seal areas where there may be air lose or gaps around door handles, locks, hinges, etc.  DO NOT use the White Seam Tape on the horizontal seams between the door panel rows as this will not allow the "gap" between the panel rows to separate when the door opens and will probably pull the tape and the foil off the door.

 

11.    Question:  Is there an expectation of how much cooler the garage will be with the insulation installed on the garage door?  Is there a rating system somewhere that can give me an idea of how many degrees cooler we might be with insulation?

 

Answer:  Unfortunately there is no system to determine exact temperature differences you will experience with any of our garage door insulation products. The products are rated with an “R” or resistance value by a certified 3rd party testing organization in a laboratory environment as required by law.  An "R" value is then assigned by the testing organization.  The “R” value is a measure of thermal conductivity, and describes the rate that heat energy is transferred through a material.  The higher the “R” value the better the insulation material.
  We can’t tell you how much of a difference the temperature will be with the insulation on your door because of a variety of issues, such as, is your attic insulated, are your side walls insulated?  Is there a heat source in the garage like a dryer or hot water heater?  Is there air leakage around your garage door?  All of these issues factor into how much difference the temperature will be affected.

 

12.    Question:  Does the Single Foil White Vinyl insulation have white on both sides?  I have small windows on the top of my garage door and just want to make sure that it is the same basic white color on both sides.

 

Answer:  No, the “Single Foil White Vinyl” rolls have commercial grade aluminum foil on one side, that usually goes towards the door to radiate heat and cold back through the door, and white vinyl on the other side that is normally exposed to provide a more pleasing look to the door.  If you want the white vinyl to show on both sides I would recommend getting two rolls and tape the aluminum foil sides together to expose the white vinyl on both sides.  This will reduce your overall "R" value but will accomplish the look you are requiring.

 

13.    Question:  I have two new metal doors that are insulated, however, they seem to be extremely cold.  Would your insulation help the new doors even though they are insulated?  Which type of insulation would you recommend?

 

Answer:  Yes.  You currently have insulated doors, meaning the space between the door skin and the outside frame edges are filled with some type of insulation material. This also means that the PanelFoam product will not work on your door because it is designed to tuck into the recessed cavity between the door skin and the outside frame edges. That leaves us with our Foil Product.  Both the double reflective foil or single foil white vinyl will work on your door, however, because these products are designed to have an air space between the door skin and the material, that will not be possible because of the existing insulation.  With the air space you could receive up to a R6.0 with the double reflective foil and up to a R4.7 with the single foil white vinyl.  Without the air space you reduce your R-value by approximately 50%.  Will the added insulation help your situation, YES, you just won’t get the maximum performance of the product because of the lack of the air space.
