Coldstream Pond just got a whole lot warmer… and way less drafty!
We just finished wrapping this gorgeous lakeside home in premium Rockwool insulation — and let me tell you, this place is now tighter than your uncle’s grip on the last beer at a family BBQ.
No more shivering through Maine winters while the heater runs like it’s training for a marathon. No more summer heat sneaking in like that one mosquito that always finds its way inside. Just pure, cozy, energy-efficient bliss.
Thanks to Rockwool, this home is now:
• Snug as a bug in a (very well-insulated) rug
• Quieter than a library during tax season
• Fire-resistant enough to make the fire department jealous
• And so efficient your energy bill might actually send you a thank-you note

Be honest… when was the last time you were in your attic?

Last week?
Last year?
…Never?

If your attic ladder is basically home décor, there’s a good chance you might have mold growing up there and not even know it.

Moisture + poor ventilation + insulation =
🏠 a perfect mold hangout spot.

Before it becomes a bigger (and more expensive) problem, let Great Northern Insulation take a look.

✔ Attic mold remediation
✔ Insulation removal & replacement
✔ Ventilation solutions to prevent it from coming back

We go into the attic so you don’t have to. 😅

🔥 Big Building. Big Efficiency. 🔥

This large metal building was fully spray-foamed by Great Northern Insulation, transforming it into an extremely energy-efficient space that’s easy and cost-effective to heat — even in cold climates.

Spray foam insulation creates a tight thermal envelope, sealing out air leaks and locking in heat. The result?
✔️ Lower heating costs
✔️ Consistent indoor temperatures
✔️ Reduced condensation
✔️ A stronger, quieter, longer-lasting building

Whether it’s a shop, warehouse, or commercial space, spray foam is one of the most efficient insulation solutions available for metal buildings.

If you’re planning a new build or upgrading an existing structure, Great Northern Insulation has you covered. 💪❄️
