Understanding Regulatory Standards for Cavity Barriers
With advancements in construction technology, cavity barriers have become a standard element of the building process. They are used extensively by builders and installers to enhance the thermal performance as well as fire resistance of a building. Considering the importance of cavity barriers, it is essential to understand the regulatory standards prescribed by the authorities. Knowledge of these standards helps one to make an informed decision while buying cavity barriers for a building.
Testing Cavity Barriers for Insulation
The primary objective of installing cavity barriers is to achieve a thermal break. Thus, it is essential to test the cavity barrier for insulation properties before installing it. Look for the manufacturing material of a cavity barrier to understand its thermal performance. Check the R-value of the raw material. This value gives a fair idea of the thermal conductivity of the material. Polystyrene is a good insulator and is used extensively in the manufacturing of cavity closers. Reputed manufacturers typically use chemically processed derivatives of polystyrene to enhance thermal efficiency.
Also, one must check the installation process for the cavity barrier. A good barrier is easy to install and is flexible enough to accommodate into different shapes. Strike out barriers that require screws, adhesives or complex tools for fitting. The installation process should save time by eliminating the complex process of timber dummy. Compatibility is another factor to consider. It should easily accept window systems of different sizes.
Fire Performance of Cavity Barriers
Cavity barriers should not act as a transit system for smoke and fire. It should have fire resistance property. According to building regulations in the UK, any cavity near the edges or perimeter of a fire-prone element should be treated with a 100% fire-resistant cavity barrier. The only exceptions to this rule are cavities on the floor and the roof where the element should have 30-minute fire resistance property. To enhance the fire-resistance property of cavity barriers, some manufacturers add glass or fibre elements. It is important to ensure that the barrier is tested and approved for fire resistance by the concerned authority.
Acoustic Test for Cavity Barriers
Cavity barriers should have a high acoustic performance as per the building regulations. They should be used along with the internal and external wall cavities during steel-frame or timber-frame construction to reduce the transmission of noise. The cavity barrier acoustic performance is even more stringent for buildings that require mandatory sound-proofing.
Environment-Friendly Cavity Barriers
Look for cavity barriers that are manufactured from environment-friendly raw materials. They help reduce pollution and conserve the environment. PVC-U is being used extensively by cavity close manufacturers to produce environment-friendly products. These products are manufactured from recycled solid material collected from consumer waste. Encourage manufacturers who do not use harmful chemicals and environmentally-damaging gases in the production process. The use of cavity barriers manufactured by recycling helps to gain approval from the control authority concerned with local buildings.
Although not a part of standard regulations, durability is a crucial deciding factor while choosing cavity barriers. The cavity barrier should be manufactured from rugged material that can withstand extreme conditions of the construction site without fracturing. Also, cavity barriers should not get easily affected by periodical changes in the building, such as shrinkage, subsidence or thermal change.

Saving money on your heating dollars
There are many building envelope anomalies that can generate significant heat and air conditioning loss, which causes your energy dollars to be wasted in a not-so-tight home.
Sources of Air Leakage in a Typical Home
My infrared camera allows me to perform a comprehensive energy efficiency inspection within your home by locating and pin-pointing those areas where unconditioned air is infiltrating into your living areas. Most air infiltrations are located at wall penetrations (such as windows, doors, vents, etc), and at transition areas of fully insulated walls, ceilings and floors. My thermal scan will identify the smallest of insulation breaches and fissures within the concealed cavities of your walls and ceilings. I will literally show you where you are wasting your precious energy resources and your hard earned dollars. My IR camera enables me to point out exactly where your costly energy dollars are being lost. I will then assist you in determining how to properly insulate those breached areas with minimum damage to your surfaces, so you can get the most out of your heating and cooling systems for many years to come.
No access to the top side of this ceiling, but infrared detects missing insulation
An infrared inspection detects a radiator conducting heat to the exterior.
During a Re-hab, infrared imaging detects missing insulation above ceiling
An infrared home energy efficiency inspection can be used to verify problems caused by poor design, poor workmanship, or material failure. With the ridiculously high priced heating fuel today, my energy audit can pay for itself in as little as one year. This is the ideal inspection to conduct for numerous situations in a typical home…
1) Use my infrared services while I'm performing your Standard home inspection. This valuable option is not included in my standard home inspection fee.
2) You can hire me immediately after completion of your newly constructed home while the home or building is still under warranty with the building contractor. I can also scan your new home on construction stage inspections. (In many cases, those moisture stains on your basement walls are explained away by the builder as "during construction" moisture. It pays to confirm this before the builder's warranty expires.)
3) If you own an older home that is costing you too much in energy dollars due to excessive air drafts, I can pinpoint those problem areas where cold air is infiltrating your living space. Then, it's best if you contact a building contractor to upgrade those specific areas that I will be clearly identifying throughout your home. All efficiency information and pictures will be transferred onto a professional thermal report for your convenience.
4) An infrared energy inspection will easily locate any missing insulation behind your finished walls and ceilings. Then, you can contact an insulation contractor to upgrade the areas that I will be identifying throughout your home. These areas will also be clearly identified on a professional energy efficiency report. During this inspection, I can show you how you can insulate specific areas without removing walls or ceilings.
5) I am able to detect potential mold problems behind walls and ceilings. All moisture issues must be mitigated immediately. As I stated previously, infrared imaging does not detect the actual Molds behind your walls and ceilings, but it will detect the issues associated with Mold build-up.
6) Infrared Thermography provides you with a unique opportunity to assess the energy efficiency of your HVAC (heating, ventilating, and air conditioning) systems, including the tightness of the duct work that is located behind your walls and ceilings. In order to prevent deadly carbon monoxide poisoning, this inspection will also test for leaks throughout the vent pipes.
7) An infrared camera will locate those thermal panes that are at the beginning stages of leaking insulated gases. I am able to locate any broken seals in double/triple pane windows that do not visually show signs of condensation as of yet.
Windows look great visually, but infrared detects three thermal barrier leaks
As you can see, having an infrared energy efficiency inspection makes it much easier to positively pinpoint problems throughout your home, instead of simply making an educated guess without the camera. An IR inspection also allows me to communicate my findings with greater understanding to you (the homeowner) instead of just "speaking another language." As one client had put it very clearly, "This inspection lets my eyes make sense of what my ears are hearing." Now that makes perfect sense, Right?
The dark blue areas indicates that insulation is missing in this area
Thermal imaging pictures combined with digital photographs can greatly enhance your understanding of just what the problem is and how to go about having it repaired with minimum damage to the home. My final energy efficiency report will enhance your ability to deal directly with the contractors that may be performing the repair work for you. All you have to do is show your contractor the infrared energy efficiency report and they will fully understand your issues. After your contractor completes their upgrade, and before you make any final payment, you can then contact me to perform a final scan to verify that all work was performed correctly.
Looks Great visually, until I detect insulation defects with thermal imaging
