What is loft insulation and how does it work?
Loft insulation works by reducing the amount of heat lost from your roof – reducing the amount of fuel you need to burn for heating and saving you money. When your home is heated, a lot of that heat escapes through your roof, both through conduction and convection.
What is the purpose of loft insulation?
Insulation between the joists keeps warmth in your living space below and creates a cold loft, while insulation in the rafters allows you to keep warmth in the roof space as well. Other benefits of roof insulation include: Lower heating bills. Improving your home’s energy efficiency rating.
Why is loft insulation bad?
Fibreglass Insulation can cause various different health problems, such as: The tiny fibres of glass from the insulation can irritate your skin and eyes. With too much contact comes the ‘irritant’ called contact dermatitis (inflammation of the skin). Breathing in the fibres can also hinder breathing.
What is the requirement for loft insulation?
The Government say that you cut your energy bill by up to 20% through effectively insulating your loft. The recommended depth for loft insulation is 270 millimetres for glass wool, 250 millimetres for rock wool or 220 millimetres for cellulose.
Should you remove old loft insulation?
In most circumstances removing your old insulation isn’t necessary and it can actually be quite beneficial to leave it. This is as most insulation will retain its thermal properties so leaving it in place will mean that you continue to benefit from it whilst also having an additional layer of insulation on top!
How long should loft insulation last?
Insulating your loft, attic or flat roof is an effective way to reduce heat loss and reduce your heating bills. Installed correctly, loft insulation should pay for itself many times over in its 40-year lifetime.
Does loft insulation make a difference?
The most obvious difference offered by an insulated loft is the saving in energy bills, and it’s very simple here. It’s estimated that a quarter of all the escaping heat from a building goes through the roof. That means you could recover the modest cost of the insulation in as little as two years.
Can you put too much insulation in loft?
As long as you ventilate your property properly, you can have as much insulation as you like within reason. The trick with loft insulation is to balance the amount of insulation you have with the amount of ventilation necessary to prevent damp. As long as you get that balance right, you should be fine.
What type of loft insulation is best?
Sheet Insulation Firm boards of either synthetic or natural materials, this is the best solution for insulating the underside of your roof. The boards provide highly effective insulation for your loft space and can also be decorated over. The downside is that sheet insulation tends to be the most expensive type.
Can loft insulation cause sore throat?
Short-term Exposure Direct contact with fiberglass or breathing airborne dust containing fiberglass may irritate the skin, eyes, nose, and throat. The symptoms of irritation are often nonspecific, temporary, and may include itching, coughing, or wheezing.
What is wrong with Fibreglass loft insulation?
Fibreglass Insulation: The Disadvantages If laid in the loft, it should be covered by boards and not touched. If it becomes wet, it loses its insulation qualities, making it ineffective. This can happen if the product becomes directly wet (ie if there is a leak in the roof), or if it is affected by condensation.
Does fiberglass stay in your lungs forever?
Fiberglass Insulation Particles Have Low Biopersistence But a biopersistent fiber doesn’t dissolve in the lungs immediately and stays. In fact, the typical fiberglass insulation dissolves within 10 days (compare this to over 5,000 days for asbestos insulation of the past).
Should loft insulation go to the edges?
Insulation should be continued right to the edge of the ceilings but it shouldn’t block the eaves’ ventilation. You must also avoid laying insulation over recessed light fittings or cables in the loft space that may overheat.
How thick should my loft insulation be?
The recommended depth of blanket style insulation (glass or mineral wool) for a loft is 250 to 270 mm. If you already have insulation, but it was put in some time ago, it is worth checking the depth, as only a few years ago the recommended depth of insulation was 200mm, and before that it was as low as 100mm.
Can kingspan be used as loft insulation?
Using rigid insulation board as loft insulation Some people may prefer to use rigid insulation board to insulate the loft space – for example Celotex or Kingspan – the process is pretty similar to above, although you will need less depth to achieve the same insulation levels (than mineral wool).
