Cavity Wall Insulation How It Works And How You Can Get It …

One of the best ways to save on your heating bills and make your home warmer in winter is to install ‘cavity wall insulation’. Plus if you choose the right installer you can get the job done professionally for a very low price, with a 25 year guarantee. In fact some people can get it done completely free. The following article explains all about cavity wall insulation and how to get it installed for less.

In most UK houses built after the 1920s, the external walls are made of 2 layers with a small air gap or cavity in between them. If your home has unfilled cavity walls, a considerable slice of your energy bills will be spent heating the air outside. In fact it is estimated that around 35% of the heat from your home is lost through the walls.

Filling the gap between the 2 walls of a house with an insulating material massively decreases the amount of heat (and money) that is escaping through your walls. This could save you between £130 and £160 a year on your fuel bills for an average house, according to the UK’s Energy Saving Trust, and pay back the cost of installation in under 2 years. It will also prevent around 1 tonne of CO2 emissions each year, so makes a significant contribution to fighting Climate Change. Plus having your cavity walls insulated will make your home more comfortable by evening out the temperature in your home, help reduce condensation, and also keep your home cooler in hot summer weather.

This is a job that is definitely best done by a professional, as it can be quite technically demanding and requires specialist equipment. However, despite paying a contractor, it can be done for little money. This is because the large UK gas and electricity companies heavily subsidise the cost of insulation through certain contractors, in order to reach their carbon reduction targets set by the government. Typically they pick up 30 to 70% of the bill, no matter what your income. The contractor will also take care of all the paperwork, so that you automatically get these subsidies. In addition, if you receive certain state benefits, the government will pick up the rest of the cost so you can get your home installed completely free. When you get a quote from a contractor, they will be able to tell you whether you qualify for these grants.

How is cavity wall insulation installed? The cavity wall is injected with insulating material by drilling small holes in the external wall through the mortar joints. The holes are generally around 2cm wide and are made good after the injection by the installer. The material injected is normally ‘mineral wool’ (fibres made from rock or glass), polystyrene beads or white foam. All materials have a similar insulation performance. The insulation normally takes about 2 hours to install, but the time does depend on the size of the house and other factors such as access.

How do you know if your house has cavity walls? Most houses built after the 1920’s have been built with cavity walls. An easy way to check is to look at the brickwork in your outside walls. If all the bricks are laid the same way, with just their sides showing (rather than their ends), then you have cavity walls. But you don’t need to make sure of this yourself. All good insulation contractors will offer you a free no-obligation insulation survey, when they can check for your and let you know what is possible.

All reputable cavity wall insulating contractors in the UK are members of the Cavity Wall Insulation Agency (CIGA) guarantee scheme. This scheme gives you a 25 year guarantee on your cavity wall insulation, so that you can be completely confident in the quality of the work. Plus you will be able to pass this guarantee on to any future purchaser of your house, which will help contribute to your house’s value.

If you are interested in installing cavity wall insulation, you should contact a reputable contractor to request a free no-obligation survey. You can do this through the site mentioned at the bottom of this article (go to the page about insulation), or else several contractors advertise on the Internet (if you type in ‘cavity wall insulation’ into Google)

Does Great Tragedy Always Produce Great Change? by Ian McCoy

American environmentalism often wins its biggest victories after major destructive events. An oil spill and a burning river in 1969 led to new anti-pollution laws and the Exxon Valdez disaster helped create an Earth Day revival in 1990 and sparked a landmark clean-air law.

But this year, in the worst oil spill in U.S. history—there has not been the same kind of drive into the debate over climate change and fossil-fuel energy.

The Senate is still gridlocked; opinion polls haven’t budged much. Demand for petrol (gas) is going up, not down.

Environmentalists say they’re trying to turn public outrage over oil-smeared pelicans into action against more abstract things, such as oil dependence and climate change. But they are also facing a political moment deadened by a bad economy, suspicious politics and lingering doubts after a scandal over climate scientists’ e-mails.

It seems that people’s anger is focussed on BP and hasn’t been automatically connected to some sense that there’s something more fundamental wrong with our relationship with the natural world.

The story of 2010 is not that nothing happened after the BP spill; -it’s that much of the reaction has focused on preventing accidents — on tighter scrutiny of rigs and mines — rather than broader changes in the use of oil and coal.

Last year, the House of Representatives passed legislation that would create a “cap and trade” system for reducing greenhouse-gas emissions. That bill probably won’t fly in the Senate because of concern over rising energy costs — and a compromise is still being worked out.

Meanwhile, for the environmental groups trying to break this logjam, it’s hard to imagine a more useful disaster. The BP oil spill has made the intangible — the cost of fossil-fuel dependence — into something tangibly terrible. Environmental activists have held “Hands Across the Sands” events at gulf beaches to protest offshore drilling, and in DC they spelled ”Freedom from Oil” on the Mall with American flags. They have organized calls to Congress and have held viewing parties to watch films about oil dependence.

We at just4theplanet commented a short while about the USA “stepping up to the plate” over climate change legislation. This is probably their best chance to pass a comprehensive bill

But in public opinion polls taken after the spill by academics, 53 percent of people said they were worried about climate change. That was only slightly different from January, and still down from 63 percent in 2008.

There may be distrust of climate science among a small group after the “Climate-gate” scandal last year, in which stolen e-mails seemed to show climate scientists talking about problems in their data. But as we reported last week, those scientists have been repeatedly cleared of academic misconduct.

What is even more worrying are U.S. government estimates that show public demand for gasoline and electric power is looking stronger now than last year at this time. So if these disasters have made individuals start conserving their energy use – there is not much empirical evidence to back this up.

All of this makes a sharp contrast to 1969, when a far smaller oil spill — 100,000 barrels (4.2 million gallons) — hit beaches near Santa Barbara, CA.

That spill triggered new restrictions on offshore drilling and, along with other disasters such as the fire on Cleveland’s Cuyahoga River; it helped spark the first Earth Day in 1970. In the years afterward, the government imposed historic new restrictions to protect clean water, clean air and endangered species.

This year’s spill, hit in the era of recycling, organic food and hybrid cars, has revealed a worrying shift toward quieter, less ambitious environmental politics.

One reason is the economy: Concerns about unemployment have made the public and elected officials wary of the costs of change. People still remember $4-a-gallon gasoline a couple of summers ago, and don’t want fossil fuel to become more expensive. So it seems that great tragedy can bring great change – but it depends on the timing. When people are very concerned about the economy – this overrides any other concerns – including the environment.

Another factor was likely the site of the spill. Louisiana residents, who are among the most affected by the oil, have vented anger at BP specifically — but not as much against the wider oil industry, which plays a vital role in the state’s economy.

Perhaps there is also a feeling which runs deep in the American psyche that the government cannot really control this stuff anyway. But at 11 weeks after the spill, some historians say it’s too early to say it won’t alter national environmental politics. In 6 months to a year we shall have to see what has been done. But we at just4theplanet repeat what we said previously – please America- don’t neglect our planet for the sake of the mighty dollar.
