- 40mm bonded polyurethane core
- Thermal break at every section joint
- Full perimeter seals, all four edges
An insulated garage door has a foam core between two skins rather than a single sheet of steel or aluminium. In Centurion the reason people buy one is usually what the garage has become. A large share of the doubles here are now part workshop, part gym, part home office or part flatlet, and an uninsulated door makes that space unusable by mid-afternoon.
Insulated garage doors we supply in Centurion
- Insulated steel sectional doors, the standard and strongest option.
- Insulated aluminium-faced doors where the finish matters on the elevation.
- Insulated roller shutter doors for low-headroom garages that still need the performance.
- Full perimeter seals, without which the insulation in the panel does very little.
Garages that have become rooms
Where a garage is a gym, an office, a studio or a flatlet, the door is the largest uninsulated surface in the room and it usually faces the afternoon sun. An insulated panel with proper seals changes the space more than anything else you could spend the same money on.
Noise, and why it matters in a cluster
In the clusters through Die Hoewes, Highveld and Midstream the garage frequently shares a wall with a bedroom. An insulated door runs noticeably quieter, both because the panel does not drum and because the extra stiffness stops the door flexing against its rollers.
Seals matter as much as the core
An insulated panel with a fifteen-millimetre gap under it is a compromised door. Bottom, side and head seals are part of the specification rather than an accessory, and they also keep out dust and driven rain.
Insulated and cold storage doors for business
Temperature-controlled areas in the food and pharmaceutical distribution buildings along the N1 corridor need insulated curtains with proper sealing, and often fast operation so the opening is not standing open while the temperature leaves. That is a different specification from a domestic insulated door and we quote it as one.
Weight, balance and the operator
Insulated doors are heavier. The balance components are rated to the finished door and the operator is sized on the real mass. Fitting an insulated door onto hardware set up for a single-skin door is the most common reason one fails early.
Estate approval for an insulated door
Insulation is inside the panel, so the visible face can still be built to the estate specification. We match the profile and colour and supply the specification for the committee, so you get the performance without an argument about appearance.
What an insulated garage door costs in Centurion
More than a single-skin door, and worth it where the garage is used for something. Priced on opening size, facing material, finish and automation. We will tell you when you do not need one.
Common questions
About insulated garage doors
If the garage is attached to the house, has been converted into a room, or has a bedroom above it — yes, clearly. If it is a detached garage storing a car and a lawnmower, the money is better spent on a heavier gauge or better locking.
Our standard sectional door uses a 40mm section with a rigid polyurethane core bonded to both skins. Because the foam bonds rather than sits loose, the section is stiffer than a single sheet of the same weight and does not drum.
Noticeably, in both directions: the boom of the door itself and traffic noise off the street. It is often the real reason people upgrade when there is a bedroom over the garage.
Low-headroom track kits recover part of the requirement. Beyond that a sectional door will not fit, and we get part of the benefit with an insulated roll-up curtain and heavier perimeter sealing instead. Measure lintel to ceiling and send us the number.
