Garage Door Insulation Kit – Our Top 3

What is insulation

Buy from Amazon!

Garage doors influence a lot the overall temperature because if the garage is not well thermal insulated you will have big heat losses.

If you do a cost-benefit analysis you will find out that you lose a lot of money if the house and garage don’t have efficient thermal insulation.

Insulating the garage doors is a really cost-effective and easy to apply the measure to reduce heat bills and to make your garage comfortable.

The insulation R-value refers to the insulation capabilities of the material used, so bigger values mean more insulating power.

Why do we need garage door insulation

Heat exchanges can happen in three different ways like radiation, convection, and conduction.

So when we speak of radiation we are thinking of the heat radiated from

the sun that will be transferred through the atmosphere directly to the uninsulated garage door.

Convection refers to the movement of warm air that is less dense upward and the downward movement of cold air.

So raised heat will pull cold air from outside allowing cold to infiltrate the garage space.

Conduction is a property of a material to transfer heat at a molecular level and usually garage doors are from with metal.

The sun will directly beat down on the garage door and the heat will accumulate because the metal is a very good heat conductor.

The metal doors used for garages are inefficient when regards to thermal isolation and also thermal comfort.

R-value represents the resistance of a material to conduction and metal has a really low one, needing added insulation with materials with high R-value

Without proper insulation of the garage doors even if the walls are perfect insulated you will still have great thermal variations and exchanges.

Adding a reliable insulating system you will make a big difference balancing the micro-climate of your garage.

These are very cost-effective solutions that will efficiently improve the quality of your working space making it more heat-efficient.

Having insulation on your garage door will ensure an efficient barrier against high-temperature fluctuations

Insulation types for garage doors

Buy from Amazon!

Manufacturers have developed three different methods to isolate garage doors like batt insulation, foam board insulation, reflective insulation.

The Batt insulation uses rolls of rock wool or fiberglass that is fluffy in a layer.

Because it comes as a thick fluffy layer it is a great insulating material and can be easy installed.

But if you have not enough space and you must compress it then it is not suitable for your use, compressed batt insulation is not good.

The rock wool is a great material for insulation and has fire retarding properties being a bit more expensive than fire glass.

The Foam board insulation uses rigid panels that are similar to Styrofoam.

This kind of material can be used on wood and metal garage doors to better insulate them.

The foam board has a lower R-value than batt insulation but when you cannot use batt insulation foam is perfect being less thick.

These foam panels must have a foiled face to avoid becoming a fire hazard.

The Reflective Insulation is made of a flexible insulating material which is covered and surrounded by a shiny foil.

This kind of insulation is used in summer to help keep garages cool and can be used in combination with other types.

Garage Door Insulation Kit – Compatibility

Most of these insulating kits are manufactured and designed for metal garage doors that have side channels.

The side channels are perfect to fit in fiberglass sheets or solid foam core.

For wood garage doors you can use the adhesive tape to secure the insulation.

What is very important when you use foam panels is that you must check to see if they are fire rated and have vinyl or foil facing.

Without these facings, foam panels are highly flammable and you should only use special kits that are designed for this purpose only and not any kind of foam panels.

If you aim to reduce heat from your garage then you should use radiant insulation kits.

This kind of insulation is good at keeping heat out of your garage and can be used in combination with rigid foam core insulation.

To secure this kind of insulation you will need to use double-sided adhesive tape.

Reflective insulation is suited more for very hot areas and the thicker insulation for colder areas.

Insulating material addresses not only the thermal changes but also fumes, noises, and some security issues.

To insulate your garage doors means to ensure a good working environment for your enjoyment.
