One of the most common questions we receive from investors planning projects in cold regions sounds something like this:

"Is your insulation system suitable for -40°C?"

It's a completely understandable question.

But strictly speaking, insulation systems do not "handle" temperatures at all.

Because insulation doesn't generate heat.

It only slows down the movement of heat.

That may sound like a small distinction, but it changes the way cold-climate accommodation should be designed, discussed and evaluated.

The Thermos Bottle Example

Imagine pouring hot coffee into a thermos bottle.

Several hours later, the coffee is still warm.

Did the thermos bottle create heat?

Of course not.

The coffee was already hot when it entered the bottle.

The thermos simply slowed down the rate at which heat escaped into the surrounding environment.

Buildings work in exactly the same way.

Insulation helps keep heat inside.

It does not create the heat in the first place.

What Happens Without Heating?

Imagine a well-insulated room with triple glazing, insulated walls and an insulated roof.

Now imagine that all heating equipment inside the room is switched off.

The room may stay comfortable for several hours.

It may even remain relatively warm for a day or two.

But eventually, the indoor temperature will become the same as the outdoor temperature.

It has to.

Heat naturally moves from warmer areas to colder ones until equilibrium is reached.

Insulation simply slows down that process.

It cannot stop it.

Without heat input, there is no heat to preserve.

There Is No Such Thing as "Enough Insulation"

Another misunderstanding we occasionally encounter is the idea that colder climates simply require thicker and thicker insulation.

Following that logic, if 20 mm of insulation is insufficient, perhaps 50 mm is better.

If 50 mm is still not enough, perhaps 100 mm would solve the problem.

Eventually the question becomes:

"Why not simply use one meter of insulation and eliminate heat loss entirely?"

Of course, that isn't how buildings are designed.

Every additional layer of insulation reduces heat loss, but every increase delivers a smaller improvement than the one before it.

Meanwhile, wall thickness, construction cost, transportation cost, usable interior space and construction complexity continue to increase.

We once discussed a project with an investor from a very cold region who was concerned that 20 mm polyurethane insulation could never be sufficient for local winter conditions.

The concern itself was reasonable.

But if insulation thickness alone determined comfort, the logical conclusion would simply be to keep increasing thickness indefinitely.

Real projects rarely work that way.

Good building design is rarely about maximizing a single parameter.

It is about finding the right balance between thermal performance, construction cost, operating cost, available space and guest comfort.

This is why there is no universal insulation thickness for cold climates.

A successful project in northern Canada may use a completely different strategy from a successful project in Iceland or Mongolia, even if their winter temperatures appear similar.

The objective is not to eliminate heat loss.

The objective is to reduce heat loss to a level where comfort becomes economically practical.

The Purpose of Insulation Is Surprisingly Simple

The purpose of insulation is not to make a room warm.

The purpose of insulation is to reduce how quickly a room becomes cold.

From an engineering perspective, that difference matters enormously.

A better insulation system usually means:

• lower heating demand;
• smaller heating equipment;
• lower operating costs;
• more stable indoor temperatures;
• improved guest comfort.

But none of those benefits exist without a heat source.

Insulation and heating are not alternatives.

They are partners.

Insulation Works Both Ways

Another misunderstanding is that insulation is only useful in cold climates.

In reality, insulation works in both directions.

During winter, insulation slows down heat escaping from the building.

During summer, it slows down heat entering the building.

The physics is exactly the same.

Only the direction of heat flow changes.

This is why the same insulation system that improves comfort during a Canadian winter can also reduce cooling demand in places such as Australia, the Middle East or Southeast Asia.

Insulation is not a winter technology.

It is an energy management technology.

Its purpose is not to make buildings warm or cool.

Its purpose is to help buildings maintain whatever indoor conditions people are trying to achieve.

The Better Question

Because of this, we rarely think the question should be:

"Can this insulation system handle -40°C?"

A more useful question is:

"How much energy is required to maintain a comfortable indoor temperature when it is -40°C outside?"

This changes the discussion completely.

Imagine a guest room maintained at 22°C while the outdoor temperature is -30°C.

The building must continuously overcome a temperature difference of more than 50°C.

At that point, comfort is no longer determined by insulation alone.

Window performance, air tightness, ventilation strategy, wind exposure and heating efficiency all become equally important.

This is why two buildings with similar insulation thicknesses can perform very differently in real operating conditions.

What This Means for Glamping Projects

For glamping investors, this misunderstanding often leads to unrealistic expectations.

We occasionally hear questions such as:

"If we increase the insulation thickness, can we avoid installing heating equipment?"

Or:

"If this insulation is suitable for -20°C, how thick does it need to be for -40°C?"

Unfortunately, building physics rarely works that way.

Insulation can reduce energy consumption.

It can improve comfort.

It can make heating systems more efficient.

But it cannot replace heating.

Successful cold-climate accommodation is not built around insulation alone.

It is built around the relationship between:

• the structure;
• the insulation system;
• the glazing system;
• the heating equipment;
• the local climate;
• and the guest experience.

The projects that perform best are usually the ones where all of these elements are considered together from the very beginning.
