Insulated Pedestrian Doors
Insulated steel pedestrian doors are a step up from standard single skin options in terms of performance of thermal efficiency, rigidity, and have a more solid overall feel. They are ideal for garages, workshops and utility room spaces, giving you easy access with the added benefit of maintaining the comfort and security of the space throughout the year.
Commonly referred to as garage side doors or insulated personnel doors, these door models are constructed with double skinned steel door leaves. The construction has a notable difference in strength and performance.
What Makes Them Insulated
This door has a double skinned steel construction with insulation sandwiched between the inner and outer steel panels. Double skinned means a stronger, more stable door leaf and less flex during use.
The insulation helps to reduce the amount of heat loss through the door leaf and is particularly useful if the garage is used as a workspace or is attached to the house.
The Benefits of a Double Skinned Construction Include:
✓ Improved security because of the more rigid structure.
✓ Resistance to twisting or warping over time.
✓ A more solid feel when opening and closing the door.
Matching Insulated Garage Doors
These insulated pedestrian doors often match the designs of insulated sectional garage doors by prominent suppliers such as Carteck and Hörmann. As a result, they are able to provide a consistent panel design and matching surface finish and colour across both doors.
For matching insulated side hinged garage doors, there are also options available, allowing for a consistent look and design across the entire garage.
GDO Pro Range Options
GDO Pro 20
The GDO Pro 20 is the go-to option for overall value for money and performance. These doors are made to measure as standard, so you get a better fit without needing to work around fixed sizes. The insulation provided is substantial along with the security performance.
With 32 colour options available, it’s easy to match the door to existing garage doors or the surrounding property. The Pro 20 also pairs well with equivalent insulated side hinged garage door models for a consistent finish.
GDO Pro 51
The GDO Pro 51 offers higher insulation performance, making it a good choice where thermal efficiency is more important. Like the Pro 20, these doors are also made to measure, allowing for a precise fit within the opening.
Supplied Pre-Assembled for Easy Installation
All personnel doors in this range are offered as complete, pre-assembled units including the door leaf, frame, hinges, locking systems and handles.
With all factory-fitted and aligned components, installation is simple. The door set is positioned in the opening, levelled, and fixed in place.
For best results, the opening should be square and the floor should be level. This ensures the door set operates correctly right from the start and makes the installation process easier.
Weather Protection
These insulated steel pedestrian doors are designed with weather protection in mind. Seals around the frame help reduce draughts and water ingress, which makes them ideal for exposed locations.
Various threshold options are available depending on the installation and how the door will be used. This allows you to balance weather tightness with ease of access, particularly where there may be frequent foot traffic.
Made to Measure as Standard
Most models of these types of doors are made to measure, which helps achieve a cleaner fit and finish. It also reduces the need for on-site adjustments or infill work.
When ordering, it’s always worth allowing a small fitting tolerance to make positioning and levelling easier during the installation process.
A Better Access Door for Everyday Use
Insulated steel pedestrian doors provide an ideal access solution for environments where a standard single skinned door may not provide the required level of security or protection.
The double skinned construction makes these doors stronger and more stable and provides better protection compared to a standard single skinned construction door. This makes them the ideal access solution for environments that are expected to have a high level of use.
Whether matching a Carteck or Hörmann sectional garage door, or choosing a GDO Pro 20 or Pro 51 for a made-to-measure solution, these doors offer a well-balanced combination of performance, security and ease of installation.
