From Freezing to Comfortable: How Insulmax^®® Transformed a Cold Farm Cottage

Sandra knows firsthand how cold her farm’s worker cottage can get—because she used to live in it herself. Located on a rural property north of Christchurch, the old farmhouse had underfloor and ceiling insulation, but it still felt freezing in winter.

"We knew how cold the house was, even with insulation in the ceiling and floor. You could literally feel the wind whistling through the cupboards," Sandra recalls. When she decided to insulate the walls, she wanted a solution that wouldn’t require ripping the house apart.

A Simple, Non-Invasive Solution

Sandra discovered Insulmax^®® and was impressed by the ability to insulate existing walls without removing any linings. She contacted the Christchurch Insulmax^®® team, who walked her through the process and explained how the product is water-resistant and designed for long-term performance.

"The team was efficient and professional. They explained everything clearly, and the job was done incredibly quickly—in just one day," says Sandra.

Once the insulation was installed, the team returned a week later to patch and colour-match the exterior, leaving the home looking seamless.

Immediate and Noticeable Results

The difference was felt straight away. Sandra’s farm manager, Luke, noted that after one winter with the insulation installed, the cottage held heat significantly better.

"Now, the room actually retains heat. The heat pump doesn’t need to run as long, and it’s so much more comfortable," he says.

The Right Choice for Comfort and Efficiency

For Sandra, the decision to retrofit Insulmax^®® was about more than just warmth—it was about ensuring her farm’s worker accommodation was comfortable and efficient.

"The whole process was seamless and easy. If I had to sum it up in three words, I'd say efficient, professional, and seamless. I’d absolutely recommend Insulmax^®®," she says.
