Established in 1984, Thermguard has spent more than 40 years helping South Africans create warmer, cooler and more energy-efficient buildings.
Our locally manufactured cellulose-fibre insulation is made primarily from recycled newsprint and professionally installed into roof and ceiling spaces. The material forms a continuous insulating layer around roof trusses, pipes, wiring and other difficult-to-reach areas, helping reduce heat loss during winter and heat gain during summer.
Thermguard is supported by a national network of approved installers and distributors, allowing us to provide professional insulation solutions across South Africa. Today, our experience, technical performance, product quality and commitment to sustainability remain at the heart of the Thermguard brand.
Genuine reviews from Therm Guard customers across South Africa.
Thermguard is dedicated to enhancing people's lives through our products and our service. Our manufacturing plant is ISO 9001:2015 rated, and our commitment to compliance and continuous improvement has kept us the trusted, tried-and-tested frontrunner in thermal roof insulation for over four decades.
However, Thermguard is about more than just an exceptional product, we also excel in the service we provide. Our nationwide network of approved installers are among the best in the country, and we have the reviews to prove it. With over 40 years of industry experience, we take pride in helping thousands of South African households and businesses every year reduce heat loss by up to 92% through their ceilings.
What's more, sustainability is at the core of everything we do. Thermguard is made from 80% recycled newsprint that would otherwise fill up landfills, uses 10 times less energy to manufacture than glass fibre insulation and 14 times less than polyester insulation, and requires no water in production. This "double green" effect - saving energy in your home while using low embodied energy to make - means every bag we produce is doing double duty for the planet. By choosing Thermguard, you become part of a genuinely sustainable way to build.
We are always looking to expand our network of high-quality installers in South Africa. It is free to be a part of our network, and there is no membership or hidden fees.
You only pay for the leads you receive. We can help you, if you’re interested in reaching out to more customers and expanding your business in different regions in South Africa.
