Cold Weather Protection That Keeps Water Moving
Cold weather can present real challenges for underground infrastructure. When temperatures drop and frost penetrates the ground, manholes and valve chambers can become vulnerable to freezing conditions that affect system performance.
For municipalities operating in colder climates, protecting these structures is an important part of maintaining reliable service throughout the winter months.
One solution designed specifically for this challenge is the Frost Shield Kit, an internal insulation barrier installed inside manholes to help reduce frost penetration and protect critical components from freezing.
Why Freezing Can Affect Underground Infrastructure
Although much of a water system operates below ground, frost penetration can still reach manholes and valve chambers. These structures often create a pathway for colder air to reach deeper parts of the system.
When freezing temperatures reach components such as valves or fittings, operation and maintenance activities can become more difficult.
In northern climates, municipalities often look for ways to reduce the impact of frost inside these structures.
Using Insulation to Reduce Frost Penetration
One approach used in municipal infrastructure is the installation of an internal insulation barrier inside a manhole or catch basin.
By installing an insulated barrier at a selected elevation inside the structure, it is possible to reduce the movement of colder air deeper into the manhole. This helps maintain more stable conditions in the lower portion of the structure where valves and other components are located.
This concept is the basis behind the Frost Shield.
A Practical Solution for Cold Climate Infrastructure
The Frost Shield Kit is designed to act as an internal insulation barrier within a manhole or catch basin.
Installed inside the structure, the barrier helps separate colder upper air temperatures from the lower portion of the manhole where infrastructure is located.
Because the system is designed to fit through a standard 20 inch frame and cover, it can be installed in many existing structures without major modification.

FAQ
What is a Frost Shield used for?
A Frost Shield is an insulation barrier installed inside a manhole or catch basin to help reduce frost penetration and protect underground infrastructure from freezing conditions.
Where are Frost Shields typically installed?
They are commonly used in manholes, catch basins, gate valve chambers, and air release valve chambers where freeze protection is required.
Can a Frost Shield be installed in existing infrastructure?
Yes. The Frost Shield Kit is designed to fit through a standard 20 inch frame and cover, allowing it to be installed in many existing manholes.
Does the Frost Shield replace the manhole cover?
No. The Frost Shield is installed inside the manhole barrel below the frame and cover and acts as an internal insulation barrier.
Is the Frost Shield load bearing?
No. The Frost Shield is designed for insulation purposes only and is not load bearing.
