What are the benefits of Cavity Wall Insulation?

Guest Blog from Domestic & General Insulation Ltd

Having a good insulation solution is something that is often overlooked by homeowners, with many seemingly disregarding the extra savings and related benefits that having a full loft and wall insulation system can provide for them. Masses of heat is lost through the walls and lofts of homes every year, thanks to their poor insulation qualities, and this is something that really needs to change.

However the unfortunate thing about insulation is that there is always an upfront cost involved. No matter what the potential future benefits of the work, having the work done in the first place is often a barrier that many people simply aren’t willing to navigate past without some solid information under their belts.

With this in mind, we are going to look at some of the benefits associated with cavity wall insulation, providing as much information as possible as to why such a solution is ideal for any home that has a cavity.

Cavity wall insulation is most useful for homes that were built after the 1930s. Homes built before this time period were usually solid wall homes, which themselves had rather poor insulation qualities. For such properties, solutions like external wall insulation and internal wall insulation exist. However cavity wall insulation is required for the homes that were built with an external wall that consisted of two smaller walls with a gap in between.

So what are the benefits of cavity wall insulation? Well, for starters…

Effective cavity wall insulation reduces energy bills

Statistics indicate that approximately 45% of the heat lost in a home escapes through the walls of the property, a number that can be massively reduced with the implementation of good cavity wall insulation. This is all energy that is being paid for and then not used by the homeowner, which of course means that energy bills soar to levels that they need not be reaching. Cavity wall insulation can help to reduce the heat loss dramatically, ensuring that less energy is needed to keep a home at a chosen temperature.

Cavity wall insulation can increase the value of a home

For many people, having insulation installed is a long term investment that can also indicate that a homeowner is fully committed to settling at their property. However, with the introduction of the Energy Performance Certificate, this is no longer the case. Having insulation installed allows you to instantly add value to your property by increasing the home’s rating substantially. This serves to make the property much more attractive to prospective buyers, in addition to reducing their own fears that they would have to spend time and money to have the work done themselves.

Your home becomes much more environmentally friendly

We have already covered how having insulation can help save a homeowner a ton of money. However that shouldn’t be the only reason to have it cavity insulationinstalled. The simple fact of the matter is that cavity wall insulation makes your home more energy efficient. In doing this it makes your home more environmentally friendly and allows the homeowner to reduce their own carbon footprint. We live in an age of increasing awareness when it comes to environmental issues, so anything that you can do to make your home greener should be seen as a positive.

Cavity wall insulation can reduce condensation

Of course, the primary concern when having cavity wall insulation installed is ensuring that you keep your home nice and warm. However that isn’t the only benefit that comes with having an effective insulation solution installed.

All homes generate moisture, simply due to the fact that there will often be occasions when warm air comes into contact with a cold surface, which in turn leads to condensation. This can cause mould and black spots in the home if it is not monitored and kept in check. Having cavity wall insulation installed can prevent this, as it allows the home to maintain a warmer temperature, reducing the amount of cold surfaces that water vapour can condense on.

Cavity wall insulation is extremely tidy

Another issue that many people have with insulation is the possibility of the insulation making a home seem unsightly. After all, loft insulation requires a lot of material being placed in the attic and even older versions of cavity wall insulation could leave a home with a number of unsightly holes across the outer surface. Newer techniques in cavity wall insulation have reduced this issue substantially however, with technologies like bead lances allowing for a single hole to be drilled and used install the cavity wall insulation. In addition to this, the insulation itself goes into gaps in the property’s walls, meaning it is never visible to the homeowner.

Cavity wall insulation is something that all homeowners should look into if it is relevant to their property. The benefits that can be provided are simply too numerous to justify not having the technology installed!

Guest Blog from providing helpful advice on the dangers and health risks of exposure to Asbestos.

Which Construction Jobs have the Highest Risk for Asbestos Exposure?

The construction industry has been one of the largest sources of asbestos exposure. Before regulations in the late 1970s limited the use of asbestos in construction material, more than 3,000 asbestos-containing products were made with asbestos.

Products like cement, paint, insulation, drywall and roofing materials all contained asbestos. Workers, who mixed, installed or removed these products likely asbestos.comexperienced exposure if they failed to wear protective gear. At the time, most workers were completely unaware that asbestos could cause serious diseases later in life.

As a result, many former construction workers have developed mesothelioma, lung cancer and asbestosis. These conditions are typically fatal and treatment options usually only relieve symptoms for a short period of time. The best way to fight an asbestos-related disease is to detect it early. With symptoms taking as much as 50 years to arise, former construction workers who handled asbestos should receive annual screenings to check for an asbestos-related disease.

Jobs at Risk

Although every job in the construction industry could have placed workers at risk for inhaling asbestos, certain tasks carried higher than average risks for exposure. Construction jobs that have historically been associated with high exposure rates include:

Roofers and Siding Installers – Roofing materials have been a big source for asbestos exposure because shingles and roofing felt were made with asbestos. The installation of a roof with asbestos products or the removal of one that was built with asbestos materials certainly could result in airborne asbestos fibers.

Siding installers also faced asbestos risk factors on a regular basis. During the housing boom in the 1960s and ‘70s, asbestos siding was a very popular material. Today’s construction workers should be careful when replacing old siding on a house.

Demolition Worker – Demolition work is one of the most at-risk jobs for asbestos exposure. Asbestos fibers become airborne after being disturbed and demolition work is certain to damage asbestos products if they’re present.

Insulation Installer – Asbestos insulation has possibly been responsible for more exposure occurrences than any other asbestos product. The material was used in attics, basements, walls, electrical boxes and anywhere else that required insulation. Asbestos naturally possesses insulating and fireproofing capabilities, so incorporating it into insulation materials made perfect sense.

Drywall Installer – Before the 1980s, drywall was often made with asbestos. The installation or removal of drywall has always been an occupation with higher than average exposure risks. If asbestos-containing drywall needed to be cut to fit into a specific space, asbestos fibers were likely released into the air.

Abatement Worker – Anyone who performs asbestos abatement is certainly at risk for exposure. Abatement workers are called in to physically remove asbestos-containing materials. If done improperly, exposure can easily occur.

Although most workers fully understand the risks involved and take all precautions to avoid inhaling asbestos, accidents can happen. Some companies hire employees unfamiliar with asbestos abatement practices and do not protect them with equipment. However, it is illegal to let uninformed workers perform asbestos abatement and all safety precautions must be taken. Today, the Occupational Safety and Health Administration and the U.S. Environmental Protection Agency strictly enforce safe asbestos procedures.

There are a number of additional construction jobs that place workers at risk on a daily basis, but the jobs mentioned above presented some of the highest risks. Those who performed these jobs for more than a few years naturally have a higher chance of developing an asbestos-related cancer. However, it should be noted that there is no safe level of exposure. If asbestos-containing materials are suspected, it’s best to assume asbestos is present and to take all safety precautions.
