HOW TO MEASURE YOUR DOOR PANELS
Determine if your door has embossed panel designs or not. Then measure the panel depth to determine which size product will suit your door. Double doors require 2 packs
OPTION 1 : 28mm PANEL
Embossed panel design doors have a smaller depth for the product to sit, you will need to allow for it. This can be done by placing a ruler vertically against the protruding design and measure as shown in the photo (right); it should suit the 28mm product. Note that the when we refer to the 28mm panel this is made up of 25mm polystyrene panel and 3mm corflute panel.
OPTION 2 : 35mm PANEL
Flat panel design doors generally have a deeper depth, measure this from the back of the panel to the front of the profile. This should suit the 35mm product. Note that the when we refer to the 35mm panel this is made up of 32mm polystyrene panel and 3mm corflute panel.
FAQs
What is R-Value?
An R-Value is a rating which measures how well insulation can resist heat flow. ‘R’ stands for thermal resistance.
- R-Value level depends on a number of things such as the type
of material, its density and thickness. - Higher R-Value = Better insulation.

What if my garage door panels are a different size?
The garage door kits have been manufactured to fit standard size garage doors.
However with the increase in models of garage doors in the market they may not fit.
Often the offcuts are used to make up the shortfall however if this is not possible please go back to your supplier who can arrange fillers or a set to be specially cut. Depending on the extent of the difference there maybe an extra charge.
Do I glue the polystyrene to the door?
There is a tube of glue in each pack but is generally not needed, it can be used to secure loose panels.
Do I glue the polystyrene to the liner?
No definitely not, the liner should be cut oversize and should hold itself in place…… see instructions
What if the cavity for the thickness of the garage door is larger than 35mm?
You will need to pack out the insulation panels by cutting some thin packers from the polystyrene off cuts and then glue them to the insulation panels and then to the door.
What happens if after fitting the garage door insulation my door will not go up?
The added weight of the insulation may effect the spring tension in your door. This may require adjustment by a qualified service technician, contact the company which installed your garage door or your local garage door company.

IMPORTANT
The EXPOL GARAGE DOOR Insulation DIY Kit is made for sectional Garage Doors. Each kit will insulate a single Garage Door of approx. 5.76m2. You will need two kits to insulate a double garage door.
The polystyrene insulation and the corflute liners are supplied in 1200mm x 600mm sheets. You will need to cut the insulation panels and corflute liners to size to suit your garage door.
Some garage doors have sections wider than 1200mm for these doors you will need to use some of the offcuts to make up the shortfall and use the glue to fix them in place against the door.
Do the same with the corflute liners but make sure the pieces used to make up the shortfall have the flutes running the same direction as the larger panels. The joins can be hidden with some white tape. Do not use the glue on the liners they will stay in place if cut to the correct size.
STEP 1
Measure vertically the first door section to be installed as shown.
STEP 1A
Measure horizontally the first door section to be installed as shown. As mentioned above if your panels are wider than 1200mm you will need to make this up with 2 pieces.
STEP 2
Mark out and cut polystyrene panels as shown.
STEP 3
USE the offcuts to make inserts for the hidden vertical cavities as shown.
Note: skip this step if there are no hidden cavities in your door.
STEP 4
Install cut to size polystyrene panel as shown.
Repeat steps 1 – 3 to complete the remaining door sections. Use glue here if necessary
STEP 5
You are now ready to install the plastic door liners.
Measure vertically the door section to be installed as shown.
STEP 5A
Measure horizontally the door section to be installed as shown. As mentioned in Step 1A if your panels are wider than 1200mm you will need to make this up with 2 pieces. You can then cover the join with a strip of white tape
STEP 6
Mark out and cut plastic door liners.
Caution: A neat cut is required to achieve a professional finish.
Insert plastic door liners as shown.
Repeat steps 5 – 6 for all remaining door sections.
FINISHED
Congratulations, you now have a fully insulated garage door.
Allowing for a metal Rib
Some doors have a horizontal metal rib to add strength.
When installing EXPOL Garage Door Insulation you have 2 choices to accommodate this.
1. Cut an L notch and insert
2. Cut a spacer and insert
Please note:
Garage Door manufacturers often screw the brackets or struts onto the door frame. Sometimes the screw protrudes into the open cavity space where the polystyrene is positioned.
Please check your door and if this is the case cut out a small notch in the polystyrene so that it slides in easily. The added weight of the insulation may affect the spring tension in your door. This may require adjustment by a qualified service technician, contact the company who installed your garage door or your local garage door company.
