Why Hempcrete Homes in Lithgow Keep Their Cool (and Warmth)
Do you own a fridge? Of course you do. But here’s a question: would you ever leave the fridge door open all day and still expect your milk to stay cold?
Most people laugh when they picture it. Yet when it comes to building homes in places like Lithgow, where winter mornings can be icy and summer days can still climb high, we sometimes treat our houses just like that open fridge. We spend money heating and cooling, but without good insulation and airtight construction, much of that energy escapes.
That’s where hempcrete comes in.
Houses Work Like Fridges (When Built Right)
A fridge works because of three things:
- Good seals around the doors
- High-quality insulation in the walls
- A controlled internal climate with different zones (the fridge vs freezer)
Your home is no different. The building envelope, the walls, roof, and floor, acts like the fridge shell. The better insulated and sealed it is, the less effort your heating and cooling systems need to make.
When we talk about “thermally controlling internal spaces”, that’s just the building equivalent of your fridge maintaining a steady 4°C. Your heater or air conditioner sets the target, and good insulation keeps it there.

Why Hempcrete is Different
Conventional insulation works like a blanket, it slows heat transfer but doesn’t actively help regulate it. Hempcrete, on the other hand, not only insulates but also breathes. Its thermal mass absorbs and releases heat over time, ironing out the temperature swings Lithgow is known for.
In winter, hempcrete walls help retain warmth overnight, so you wake up to a house that isn’t freezing. In summer, they absorb excess heat during the day, releasing it later when the air has cooled. That means less reliance on mechanical heating and cooling. And lower power bills.
Long-Term Payback
Yes, building with hempcrete can be a little more upfront. But just like buying a fridge with a higher energy star rating, the payback is worth it. Over the lifespan of your home, hempcrete’s reduced energy demand can pay itself back in as little as 6–8 years, depending on your design. After that, it’s all savings.
And unlike synthetic insulation, hempcrete won’t sag, compact, or lose performance over time. It continues working for as long as the house stands.
Healthier Homes for Lithgow Families
There’s another benefit fridges don’t have: indoor air quality. Hempcrete is breathable, reducing condensation, mould, and stuffiness. That makes it especially valuable in Lithgow’s cold winters when homes are often shut up tight.
