Insulation for the home

Why Merino wool is the safe and practical choice for heat and sound insulation in your home

Homes need insulation to prevent heat or cold air from travelling from one area to another, either from outside in or within the home. Proper insulation will reduce the need for heating and cooling, having less impact on the environment and saving you money on gas and electricity bills.

In addition to fluctuations in temperature internal or external sounds can dramatically affect how pleasant a room or entire home is to be in. Insulation can increase the habitability of your home by trapping sound and blocking noises from outside your home as well as between the rooms, helping to create a greater sense of calmness in any space. With more people living in busy cities insulation has become even more important to block out the stressors of our daily lives.

Homes need insulation not just in the roof but also in the walls —especially, east and west facing dwellings that are subject to heat from the sun. Insulation between your carpet and floor and around your doors and window frames will also help to moderate temperature and sound.

So which type of insulation should you use?

It’s seems obvious that Merino wool, grown by Australian sheep, has excellent natural insulating properties when you consider the original purpose of wool: to keep a sheep warm and dry regardless of the at times extreme environments it will live in.

Merino wool fibres naturally have a coiled or crimped structure that traps air in between it. Wool itself is a bad conductor so when combined with air, another substance that does not conduct heat well, you have the ultimate insulator.

This elastic, crimpy structure also means that insulation batts made from wool — using wool fibres bonded together — will keep their shape and last longer than other synthetic materials. Placed in your ceilings, walls, door and window frames, wool insulation will significantly improve the noise and temperature control of any home.

You can also further manage heat and sound levels with your choice of interior textiles. Combine roof, floor and wall insulation with sound absorbing Merino wool curtains, carpets and other furnishings and you’ll be able to effectively help keep your home warm in winter, cool in summer and quiet all throughout the year.

Plus, Merino wool is a biodegradable and renewable resource making it a conscientious choice for our environment. Unlike synthetic materials it is also fire resistant, with a much higher temperature required for ignition than most other materials providing a safe insulation alternative for your home.
