The advantage of having an insulated garage door over a sectional garage door is that you can cut down your power bills as less power will be required to heat the garage, as less heat is lost to the outside environment, while in winter you will be able to keep the garage at a warmer, more comfortable temperature. It will also allow you to use the garage as a workspace or as an additional “living space “within your home. The advantage of the sectional garage door is that it is cheaper to purchase,  and will require a cheaper less powerful motor as the door, in and of itself, is lighter.

Why choose an insulated garage door?

As mentioned above you should choose an insulated garage door for your home if you’re looking to use the garage as in a workspace on traditional living area. It is also a good option if you are looking for a way to cut down on your power bills or reduce your reliance on air-conditioning solutions, albeit at the expense of a greater initial upfront cost.

What do insulated garage doors look like?

Insulated garage doors from the outside or exterior of the home look identical to sectional garage doors.  they are composed of a number of horizontal panels which are connected to one another with a series of hinge joints.

If you find a style of sectional garage door which is appealing to you but what the benefits that and insulate garage talking offer,  it is very likely that we will be able to provide you with an insulated garage door that has the exact same appearance as a sectional garage door.

Noise reduction with insulated garage doors?

One of the greatest benefits of an insulated garage door is that it reduces noise transfer. This is great for circumstances where the garage is used as a workspace,  all for those who live on a busy street as you’ll be surprised by how much quieter your home become when less noise is carried through the garage door from outside.

What are insulated garage doors made from?

While the frame and panels of the insulated garage door are composed of Colorbond steel, the insulating material is made from either foam, foil or fibreglass.

These three materials are very effective at reducing the transfer of both heat and noise.

  • The foil is around 5 centimetres thick. it is made from a combination of aluminium foil and polyethylene foam. Higher quality foil insulation can consist of multiple layers of these alternating materials.
  • Polystyrene Foam is a more effective insulator than foil but it is not as aesthetically appealing. Additionally, it is more rigid and is likely to crack if the garage door is impacted.
  • Fibreglass is the best-looking insulation material on offer, but it is not as effective as the polystyrene foam. That being said, it is more resistant to water and mould and is the best choice for those living by the coast.

Ultimately the material from which your insulated garage door is made does not have much effect on the exterior appearance or the function of the garage door – they are all great insulating materials. The material from which the door is made is generally not of concern to the customer, rather, as long as it is effective in insulating the garage door, the customer is generally happy with the door, regardless of the insulation material.

Insulated garage door installation

Insulated garage doors are not too dissimilar to the more common sectional garage door when it comes to their installation and the installation of an insulated door will be within the skillset of almost every qualified garage door technician.

Insulated doors do differ from sectional garage doors as they lack hinges and are notably heavier. When the insulated garage door panels are installed, the panel edges are shaped in such a way that they fit into the indent of the neighbouring panel. This allows the door to form a tight seal when closed, assisting with the insulation of the garage door, but also creating a pinch point in which fingers can be caught and crushed. It is important to be aware of this pinch-point when installing any new insulated garage door.

Insulated garage door repair and maintenance?

Insulated garage doors need to be regularly maintained just as you would a sectional or roller door. By performing a regular visual check of the door, the motor, the spring, the tracks, and the moving parts for rust and signs of wear, you will be able to detect and address any issues that might occur. Combine a regular visual check of the door with an annual service to ensure a correctly tensioned spring, you’ll be able to get the most out of your garage door set up and notable extend the longevity of your door and motor.

How often should you service an insulated garage door?

Insulated door service is in line with other garage door services. It is recommended that the first service is performed after 12 months following the door’s installation, with each subsequent service occurring every 18 – 24 months thereafter.

It is very important to ensure that these maintenance services are completed not only to improve the functioning and extend the life of your door and motor but many garage door motor warranties require regular servicing. Avoiding the service can be very costly as it will not only increase the likelihood that an issue will occur, but the cost of addressing that issue will fall to you, rather than the manufacturer.

Insulated garage door motors

Insulated garage doors operate using the same motors as sectional garage doors. There are a huge number of suitable garage door motors on the market from manufacturers including:

  • Centurion

Which is the ‘best’ insulated garage door motor?

Garage door motors come in various size and strengths. This is to allow garage door motors to be able to lift progressively larger and heavier doors but allow for a cheaper motor for those who do not require the immense power of the largest motors. Due to this, the best motors are those which are correctly paired with your specific garage door, are reliable, provide great value for money, and is a motor that will have a lifespan spanning many years – ideally, matching the lifespan of the door.

Our personal preference when it comes to insulated garage door motors are those motors from Merlin’s Commander range. The motors in the Merlin Commander range are great motors! They are quiet, come with an industry-best 7-year warranty, and can be controlled with a remote, a wall button, and your phone! To find the best Merlin Commander motor for you, we’ll need to pair the weight of your door with the power of the motors within the range.

Do note that insulated garage doors are heavier than sectional garage doors of the same size due to the additional weight of the door’s insulating material.

Insulated garage door optional extras

It is standard for insulated garage doors to come with a motor, a wall button, and 2 remotes to operate the door. In addition to this, you can additionally purchase keypads and safety beams.

Keypads work as another wall button but are accessible from the garage exterior. As to not compromise safety and security, a PIN must be entered to allow the keypad to operate the garage door.

Safety Beams add an additional measure of safety to the door. The safety beams extend a laser beam between two points on either side of the opening. If the beam is broken by something within or passing through the garage door opening, the door will not close. This is important to prevent the garage door from crushing whoever or whatever might be beneath the garage door, which can weigh up to several hundred kilograms.

What other options are available?

Alternative garage door styles to consider are sectional garage doors, custom garage doors, and roller doors.

Sectional Garage Doors look very similar to insulated garage doors from the home’s exterior, but they do not reduce the transfer of heat and noise as the insulated doors do. If you are not looking to use the garage space as either a workshop or additional ‘live-in’ space within the home, sectional garage doors are arguably a better choice.

Custom Garage Doors are tailor-made to your requirements and design. If the style and colour options offered by insulated garage doors do not match your vision for your garage door, custom garage doors are the way to go.

Roller Garage Doors are a functional, cost-effective garage door. Roller doors offer minimal insulation and will not be suitable if insulation is something you require. But, if budget is the biggest concern, roller doors will offer you a garage door at the lowest possible price.
