About BJ Carter Ltd Builders/Insulation

BJ Carter Ltd were among the pioneers of home insulation 30 years ago, and have been bringing southerners warmer, drier and healthier homes ever since - we've even recently developed our own system, Envirowool. Envirowool is eco-friendly 100% pure southern wool and can be installed in the ceilings of new homes, older homes and commercial buildings. The wool is pumped in the ceilings and reaches areas other products can't. Envirowool is fire resistant and absorbs sound. For more information visit

We also supply and install Insulmax insulation for insulating the walls of existing homes. Insulmax wall insulation is a soft white blown mineral wool product manufactured specifically for thermal and acoustic insulation of wall cavities and is installed without removing wall linings. Insulmax is manufactured to be installed via small access holes made in the interior or exterior wall lining. We use the latest infrared camera technology to ensure that all cavities are completely filled and at installed densities, Insulmax will not settle, shrink or slump. For more information, visit our website.

For underfloor insulation we can supply and install black polythene on the ground; and Terra Lana wool blend fleece blanket under the floorboards.

Over the years, we've retrofitted hundreds of older houses and insulated new homes to the very highest standards. We've proved it's not just what's used to insulate a home that makes such a difference, it's how it's done.

Incorrectly installed insulation can detract significantly from the financial and health benefits - as well as being downright dangerous. So, unlike other insulators, at BJ Carter Insulation, we choose to use our experienced, qualified tradespeople to install all our insulation products to provide our clients with the best, and safest, results.

From ensuring there are no safety concerns - like exposed wires - to check for hidden problems, such as rotting wood, our specialist team brings extra peace-of-mind and quality to every project we work on.

We service the whole of Southland and Otago. For a free assessment, or to talk through our insulation solutions for retrofitting older homes or on new builds and commercial sites, contact the BJ Carter Insulation team.
