Roof Insulation

Thermguard Cellulose Ceiling & Roof Insulation

Thermguard Cellulose Ceiling & Roof Insulation , our flagship  insulation product  is manufactured in South Africa and has been creating comfort in homes since 1987. Reducing energy usage for home owners whilst continuously improving to ensure it remains the industry leader in insulation materials, has been the main focus of the founders of the company.

Thermguard blown insulation material is a cellulose manufactured using more than 80% recycled newsprint, a material that would have ended up in landfill and polluting our atmosphere.  Thermguard Ceiling Insulation  is environmentally friendly, fire retardant and has no harmful synthetic additives and is 100% organic and biodegradable. 

Thermguard  is installed as a dry product onto  ceilings  and will provide 100% coverage; getting into every nook and cranny assuring your hard earned cash is well spent. The product offers a better  insulation  value than ( R-Value ) other bulk insulation  materials on the market. 

Insulation reduces the exchange of heat through a surface such as a wall, attic, duct or roof. In a well-insulated home, less warm air escapes from the house during the winter, and less cool air escapes during the summer, reducing the amount of energy needed for heating and cooling (see References 1). Improving the insulation in older structures may lower your annual heating and cooling bill by up to 20 percent.

Thermguard Ceiling & Roof Insulation  is ideal for  sloped (cathedral) ceilings as well as drywall insulation to ensure sound proofing between offices. Applied onto a ceiling of a flat roof will reduce unwanted noise and increase comfort levels dramatically.

Why Seal and Insulate?

Most homes in South Africa don’t have enough insulation and have significant air leaks.  Did you know that 9 out of 10 homes in the S.A. are under-insulated? Sealing air leaks around your home and adding insulation are two of the most cost-effective ways to improve energy efficiency and comfort in your home. By tackling both projects, you can maximize your comfort and save up to 10% on your annual energy bills.


Save Energy and Money

Air that leaks through your home’s envelope − the outer walls, windows, doors, and other openings − wastes a lot of energy and increases your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills. EPA estimates that homeowners can save an average of 15% on heating and cooling costs (or an average of 11% on total energy costs) by air sealing their homes and adding insulation in attics, floors over crawl spaces and basements. 

Increase Comfort

Insulation helps keep your home warm in the winter and cool in the summer. When correctly installed, insulation can deliver comfort and savings, especially during the hottest and coldest times of the year. Sealing leaks and adding insulation can improve the overall comfort of your home and help to fix many of these common problems:
