Why Thermals and Long Johns are a must for winter months on building sites.

Thermals and Long Johns are a must for winter months on building sites.

There are few things more unappealing than the summer heat on a construction site. Sweaty, sticky workers make for an uncomfortable environment. But those conditions are nothing compared to the winter cold when outdoor work is almost impossible. The elements pose serious challenges to construction sites everywhere.

Hail, sleet and snow can all shut down a project until spring returns; rain and other precipitation can also lead to frequent delays when exterior work is involved. In this article, you will learn about the various ways in which thermals and long johns help construction workers cope with the bitter cold this time of year – and why they’re essential garments if you work outside in wintertime!

What are thermals?

Thermals are an undergarment designed to keep the wearer warm. They’re often worn underneath other layers of clothing and can also be used in sports, such as skiing or snowboarding, as well as in other outdoor activities where keeping warm is critical.

Thermals are made out of synthetic fibres that are very effective at retaining body heat. They’re also very breathable, meaning that they don’t trap excessive moisture, which is important for preventing the growth of mildew or moisture, which can cause discomfort.

There are a few different types of thermal garments available. Thermal shirts and pants are the most popular, but thermal underwear, thermal socks and even thermal headwear are also available.

Thermals are generally made of polyester and come in a variety of thicknesses, with different weights designed for different temperatures. Workers who spend a lot of time outdoors in cold weather usually prefer the thinnest and lightest fabrics they can find.

Why Long Johns?

Long johns are like thermals in that they are an undergarment designed to trap the body’s own warmth, keeping the wearer warm and comfortable. They’re made from fabrics similar to thermals but are generally heavier – often made of wool and thicker synthetic fibers, or a combination of both.

Long johns are generally worn underneath other garments, such as jeans or overalls, but they can be worn on their own in milder temperatures. Long johns are usually made in long trousers, and sometimes include sleeves, keeping the arms warm as well as the legs.

The name “long johns” is actually a misnomer, as long johns are not, and have never been short shorts! Long johns used to be loose-fitting trousers or knee-length trousers, and the name came from a brand of underwear produced in the 19th and early 20th centuries. Since long johns are a type of undergarment, they’re loose-fitting and are not generally worn as outerwear.

How do long johns benefit construction workers?

Long johns are a good choice for construction workers for a few different reasons. First and foremost, long johns trap the body’s own heat very effectively, making them ideal for outdoor workers who are spending most of their time in cold weather.

Long johns are also thick and fairly heavy, meaning that they provide ample warmth. And because they’re constructed from synthetic fibres, long johns are highly resistant to the growth of mould and mildew, making them a good choice for workers who might get wet often.

Long johns are generally thick enough to be worn alone in milder temperatures or in combination with lighter layers when the weather gets colder. Long johns are also very comfortable, making them a good choice for workers who will be spending long hours on the job.

Other ways to stay warm while working outdoors in winter

While thermals, long johns and hard hats are three of the most important pieces of winter gear for construction workers, there are a few other things workers can do to stay warm.

Dress in layers:

Wear a warm shirt and pants, and then add another layer if necessary.

Wear socks that trap heat and moisture:

Thick wool socks or synthetic socks work well.

Wear gloves:

This can help workers keep their hands warm, but be sure to choose ones that allow for dexterity.

Stay hydrated:

This is important for warmth, as well as for overall health.

Keep moving:

Moving around helps generate heat.

Choose a job that keeps you inside:

Some tasks can be done indoors, such as electrical work, plumbing and roofing.

Winter weather can be dangerous and uncomfortable, but construction workers who are prepared will be able to survive it relatively unscathed. Thermals, long johns and hard hats are essential garments that can help construction workers survive the winter months. And while staying warm can be difficult when temperatures drop, it’s important to remember that it’s never too early to start preparing for winter.
