At the first sign of winter do you dust off your heaters and throw your electric blanket on the bed? Or maybe you stock up on gas and firewood to keep you warm through those dark, chilly nights? With a green home, you wouldn’t have to do any of these things.

And the reason for that lies in proper insulation. You may be surprised to hear that a well-insulated home not only reduces your electricity bill, but it takes all the hassle out of dealing with the change in seasons.

Yes, insulation does mean a significant reduction in your heating costs. But the real benefit is that it keeps your home at an even temperature throughout the year; cool in summer and warm in winter. Green homes combine a variety of insulation materials and techniques to keep your home at the perfect temperature all year round.

Not only are the materials and techniques they use environmentally friendly, but they’re also remarkably efficient and effective. Here’s a breakdown of how a home should be insulated against the elements.

Lambdaboard: Built in-between external and separating walls

Lambdaboard is a high-quality, environmentally friendly alternative which provides superior insulation for homes. Lamdaboard is a polyisocyanurate, which is another name for a thermoset plastic. Essentially, it is closed-cell, rigid foam board set between two facers. The facers are made of a various organic materials such as fibreglass or paper.

Lambdaboard is the ideal insulating material and provides several benefits to homeowners:

  • The foam core resists moisture which reduces the risk of rising damp on walls.
  • It is made from recycled materials and can also be recycled itself which makes it really environmentally friendly.
  • It performs better than most other materials in fire tests. It will not melt, drip or spread the flame.
  • It has a wide service temperature range from -30° to 140°.
  • It has the highest thermal resistance (R-value) per 25mm of thickness which makes it the most thermally efficient insulation material available on the market.

By inserting this remarkable material in-between exterior and separating walls, the temperature of each individual room is contained and maintained. The result is that heating your home in winter is cheaper and easier.

The Lambdaboard helps to keep any heat generated within the room, which in turn makes you less dependent on other energy-hungry heat sources to keep warm in the colder months. And in summer, the board keeps the heat of the sun out, which makes interiors cool and comfortable.

Here again, you won’t have to rely on expensive and environmentally damaging air conditioners to keep the temperature down. It’s not hard to see how using this amazing material to insulate every room in a home would make it more comfortable to live in.

Hydronics radiant heating and cooling

Homes built using this method to help homeowners control and customise the temperature of their home to suit their individual preferences,  makes it a versatile and economical way to heat or cool your home.

How does it work?

Hydronics radiant systems circulate water through tubing laid in the floor between the foundation slab and the surface of the floor. They are connected to a hot water tank and gets cold water directly from the heat pump system. The feeder pipes are well-insulated which helps to maintain a consistent temperature throughout a specific area.

The system is laid out over multiple zones in the home and you can adjust the temperature of each zone individually. That means each member of the family can adjust the temperature in their area to suit their preferences.

What are the benefits?

When compared to regular methods, using water to heat or cool your home has several benefits:

  • The floor surface of the area is heated or cooled, rather than the air within it. This eliminates hot or cold spots and makes it more comfortable for the people living in the house.
  • There is no need for messy ductwork or noisy fans which means a cleaner and quieter home.
  • Dust particles aren’t circulated through the air so there’s less risk for those who suffer from allergies.
  • It’s easier to control the temperature of the building and set the temperature to suit your comfort level.

The system is compatible with any type of flooring so you don’t need to avoid using tiles throughout your home for fear that it will be cold in winter. With a hydronics radiant heating and cooling system, you’ll be able to walk barefoot across your floors no matter what time of the year it is.

Combined with the use of Lambaboard in the walls, it’s easy to see why these homes are both more energy efficient and comfortable to live in. Being able to control the temperature within your home, and maintain it without relying on expensive electricity makes a green home particularly attractive to anyone looking to buy a new home.

Any costs involved in such a system will be quickly offset by the reduction in running costs, especially as the price of electricity continues to rise. But beyond this, the knowledge that these methods are also kinder to the environment provides a benefit that cannot be measured in economic terms.

Going green doesn’t have to mean sacrificing your comfort. In fact, a green home is easier to live in and maintain, despite the perception that reducing your reliance on electricity means missing out on the convenience of modern living.

Insulated floors

Adding a layer of insulation to floors of every home, ensures that the hydronics radiant heating and cooling system is even more effective.

On its own, an extra thick screed will provide your home with insulation. It is also a good idea to insulate the pipes carrying water.

And not only in the bedrooms and living areas – the kitchen, bathrooms and domestic quarters should be fitted with these pipes and an extra thick screed. So no matter where you spend your time, the temperature of the area will always be just what you want it to be.

Innovative ceiling insulation

One popular method of insulation consists of laying a thick roll of fibre-glass or asbestos material in the roof of your home to trap the heat inside. Although it may be effective, it certainly isn’t environmentally friendly. And it makes it awkward to access your roof space should you need to install new lighting or lay any kind of wiring. But there is a far more efficient and sustainable way to insulate your ceiling.

So what should you use in place of this? If you’re concerned about safety, you’ll be delighted to know that there is an entirely green technology to insulate the roof of your home. Called Isotherm, this insulating material is completely made up of recycled plastic bottles. Not only is this material environmentally friendly, it can also be recycled. You can’t get greener than that.

And it still has some other benefits that all homeowners will appreciate:

  • Dust and water resistant
  • Non-toxic with no associated health risks
  • Non-flammable
  • Lasts longer than most other insulating materials

Choose a ceiling insulation product that is effective and gentle on the environment. Once again, you don’t have to sacrifice modern comforts for the sake of greener living. And you’ll be reaping the benefits of reduced electricity consumption and the costs associated with it for years to come.

The double benefit of insulated plumbing

Don’t let any opportunity go to waste when it comes to insulating your home. Even the water pipes should be insulated. First, cover with an insulation material which is wrapped with insulating tape. And then, benefit from the insulation in walls, floor and ceiling.

You might think this is too much, but this only adds to the savings you’ll enjoy. Obviously all this insulation means that your hot water won’t cool down in winter or your cold water heat up in summer. Via a linked-loop system hot water is available a few moments after you turn on the tap.

So you won’t need to run your taps until the water reaches the desired temperature. This means you’re saving water too. And considering what a precious resource this is, it makes perfect sense to insulate your plumbing as much as possible.

Double glazing on windows and glass doors

You may think that this would be unnecessary considering how many other insulating methods are used to make green homes comfortable and energy efficient. But every technique available must be used to maximise the efficiency of green homes.

Double glazing refers to a window that consists of two panes of glass, an outer pane and an inner pane. Because the window is completely sealed, the air between them acts as a layer of insulation. This stops the warm air inside the home from escaping during chilly winters. And in summer it has the reverse effect; preventing unwanted heat from entering your space.

Once again, this reduces your need to keep heaters or air conditioners running constantly to maintain the temperature of your home. And there are some other benefits to double glazed windows that you may not be aware of:

  • It reduces condensation which is the primary cause of mould in the home.
  • It cuts down on medium to high-frequency noise, which makes for a quieter space.
  • It’s harder to break through two panes of glass so double glazed windows and doors also act as a security measure.

Once again, a feature like this does tend to add to the cost of a home. But it’s easy to see how the benefits outweigh the initial costs.

It’s easy to see how much your energy costs will be slashed by taking advantage of these materials and techniques. Great care should be taken to ensure that every green home build conforms to the strictest safety standards. The materials and techniques used should not only be environmentally friendly, but also durable, effective and cost efficient.

A well-insulated home makes financial sense. Although it may affect the cost of your initial layout, your living costs will be significantly lower. And in less than 10 years the savings you’ll enjoy will more than make up for extra expense of buying a green home. With low maintenance costs, you’ll continue to enjoy modern comforts while also making a positive impact on the environment.
