High Specification Thermal Backer Boards Are Vital For Underfloor Heating How Run Your New Electric Underfloor Heating Economically.

The latest electric underfloor heating systems are capable of providing safe and economic heating. However there is a lot of confusion regarding claims by some suppliers of heating mats who maintain that theirs is an ultra efficient cost saving version. The fact remains that 1kw of electricity will produce 1 x kw of heating. Therefore, a floor area of say 20 square meters using 130w heating mat will produce 2.6kw of heating The secret of getting economical heating is to begin with a high specification insulation layer. The underfloor heat up time is determined by the thermal conductivity of the sub-floor that it is fitted on It is therefore vital that a thermal backing board is fitted over the sub- floor before the heating mat is fitted. This should have a thermal conductivity of 0.027(W/mk) and a U value of below 3.5 (W/mK) This thermal conductivity is a calculation of the rate at which a material will pass heat energy. This is measured in watts per square meters per degree of temperature difference (watts meters) per degree of temperature A good insulating underlay will force the heat upwards instead of letting it disperse back down through the sub-floor, meaning that far more of the heat that the matting is generating is in turn heating the room. This will in turn mean that the heating thermostat can be turned down by the corresponding degrees, thereby saving power and electricity costs. It is also important to remember that high thermal conductivity below the heat matting helps to give a fast warm up time of the floor surface -less than 20 minutes can be achieved. Thickness of the insulating backer board has a direct bearing on the thermal resistance. A thicker board having a greater thermal resistance than a thinner one, so if final floor thickness is not an issue, then go for a thicker board every time. You will also find that there is hardly any price difference between the board thick nesses. This is because the face material of the board and the manufacturing labour is the same regardless of board thickness.

When choosing an insulating backer board, compressive strength kPa is very important. Look for a board with a high rating over 300 kPa as this will ensure strength sufficient to support the weight of the heat mat, adhesive, floor tiles and any heavy appliances or furniture that will be resting on the floor. 300kPa is nearly equivalent to 30 tones per square meter. The facing of the board should be a consideration. A fiberglass scrim on either side of the board, coated with a polymer will assist in adhesion of the tile adhesive as well as providing greater structural stability. This also means that the boards can effectively be used to level up old uneven floorboards. This can be an alternative to covering the floorboards with expensive plywood which has little thermal resistance. However if the sub-floor is flexing, a plywood layer may be the only option. The boards can be cut and installed extremely quickly.

They can usually be cut with a Kraft knife and are either screwed into a wood floor, or bonded onto a solid substrate with a fast setting flexible tile adhesive. To summarize. 1. Do not lay your heating without a thermal backing board- it will waste electricity and money in the long run. 2. Buy waterproof boards that have at least 0.027 W mk thermal conductivity and a compressive strength of over 300kPa. 3. Buy boards that are mesh backed on both sides- these are slightly more expensive than un-backed boards, but will perform better.

What Is Insulation, Why Do We Have It And How Does It Work? A small science lesson about insulation: Heat moves from warmer areas to colder areas. This is the single basic principle on which the idea of insulation is based. On hot days heat tries to get inside your house and on cold days the heat tries to escape. Insulation seeks to minimise this ebb and flow of temperature by slowing the process.

Unfortunately no matter how good your home insulation is, any building always needs a constant supply from a heat generating source to maintain a steady temperature. Of course however, if you have good insulation then you will need much less heat and thus a lot less energy to achieve the same effect. Most of us learned in GCSE science about conduction convection and radiation.

Here is a brief summary of each to refresh every ones memory. Conduction This is the process that heat flows through or along one material and into another. This is done through molecular transportation. To do this, the materials must be in contact with each other. This conduction happens with all things of liquid, solid or gas substances but that rate at which it happens greatly varies depending on the substance and its state i.e. if it is a good conductor or a bad conductor. Good metal conductors include gold, silver and copper down to the worst conductors like wood and THERMAL INSULATING MATERIALS. Gases and liquids are also bad conductors BUT are prone to the other, convection. Convection The requirement for solids to lose or gain heat by this process it must be in contact with the liquid. Convection happens when a change in temperature happens in parts of the fluid thus causing the liquids density to alter. This is called ‘natural convection’. If the fluid in instead displaced and accelerated by wind or artificial factors then it is called ‘forced convection’. In forced convection the process of convection can be increased substantially. Radiation This is how heat is emitted from a body and transmitted across a space as energy. This kind of radiation is similar to radio and light waves. It does not even need air in between for it to happen, and works just as well in a vacuum. Every solid body emits energy but the rate of emission all depends on three different things. Distance between surfaces The emissive of the surfaces (shiny and light/matt and dark) Temperature differences between receiving and radiating surfaces House insulation The application of thermal insulation does not have the effect of generating heat in your house. It is still always the rule that you will have to supply heat from an inside source. There may be a rise in temperature inside the building after the installation of insulation but that will be down to the better performance and energy saving properties of better house insulation.

In recent years homeowners have become increasingly aware of the importance of good insulation. Although the government would have us believe we should do our bit for the planet, the motives for this sudden interest aren’t always that green.

The main concern of homeowners is probably cost – with energy bills spiralling and no end in sight it’s important to cut down on spending as much as possible. The better insulated your house is, the less energy you use and the less it costs.

So what are the most important bits of your home to insulate? Well, your windows actually have the potential to lose a lot of heat, especially big picture windows with a large surface area. Double glazing is the best solution and these are fitted to new build homes as standard. In older properties it can be more difficult if you want to replace the windows but match the existing character of the building, but there are specialist companies who can help.

The next important place to insulate is your loft. Heat rises so a well-insulated loft can make a very big difference. Insulation not only keeps heat in, it keeps cold out and you’ll find that your house maintains a constant temperature a lot better. This means that you never have to heat it from scratch, and it will actually be a lot more comfortable even in the summer.

It can be difficult to choose the right kind of insulation – recycled insulation is increasingly popular. One type is made from mashed up old newspapers between wooden boards (to create a sandwich) and has very good insulating properties. You can also buy natural wool insulation – this is what was used in the olden days before synthetic materials started to be produced. These have the advantage of being green products and aren’t necessarily expensive. Synthetic materials can offer good insulation and their advantage over natural ones is usually size. For example, 6 inches of one insulating material could be replaced by just 2 inches of another. It all depends on the ‘R’ value – the higher the R value the better insulator it is. If space is an issue then you’ll have to take notice of this but any good DIY shop can help. It’s actually quite easy to fit thermal insulation yourself. Most insulation comes in rolls so you just have to roll it out in your loft, being careful not to block any air flow spaces. It’s important to keep your loft space well-ventilated as this stops damp problems from forming. You should be able to fit your own insulation in a day, but if you’re unsure it’s best to get a professional to help. When choosing your new insulation it’s a good exercise to work out how much it costs compared to how much energy you’ll save over the next few years. The money savings should outweigh the cost of the insulation and this will make all the hard work worthwhile. Insulation is your hidden saving and of course, you’re helping the planet too. Author: Sylvia Kittens Sylvia Kittens lives in Harrogate, England Article Source: http://EzineArticles.com /?expert=Sylvia_Kittens Using insulated plasterboard after installing chemical damp proof … Hi, I know there have been previous posts about insulated plasterboard. My question is this: I have a terraced house approx 120-130 years old with solid brick walls, no cavity. Insulation to pitched roof We want to add extra insulation and from reading above the best would be to fix insulated plasterboard directly onto the existing ceiling using ‘no nails’ or similar and then Ceiling insulation? One of our bedrooms has apparently already been insulated on the ceiling with a layer of polystyrene before the plasterboard. As this room is much warmer than the others and the ceilings. Wall insulation – heat and noise He’s got a continuous envelope between the ground floor running up the walls to the first floor. He’ll plasterboard that on top.
