There seems to be some degree of misunderstanding here. You have a floor with cold air rising through it. Why? Because warm air rises, the wind blowing over a roof, sucks the air from inside a building. The air that is pulled in is colder and drier than the warm wet air in the home. The...

I had the same problem, a tiny hatch in the bathroom. Mine was so small, I had a problem with my shoulders. You need the think about access, from ground level and loft level. Can you get to the ladder with the things you want to take up or bring down in your hands, is there room in the...

I had this problem about 3 weeks ago. My boiler is 14 years old, fitted for previous owner, who had it serviced every year. I have had it for 9 years during which time, it has worked perfectly, without servicing. The problem was down to a blocked copper capillery tube. I pulled off the tube...

The governments idea of insulation is 12 inches or 30 cms of fiberglass. The problem is, that fiberglass is rubbish as an insulation unless its in an airtight plastic bag, or air tight container. It also needs to be an almost air tight fit between the joists which in real life is impossible...

The way to understand this is: Water vapour is created by people in their home. It is produced by cooking, washing, drying, breathing, sweating, fish tanks, flowers, plants, animals. When you breath out your breath is 100% full of water vapour. You probably breath out a litre of so every 24...

So the question is:- - Is a mild amount of condensation in the loft as descibed above (droplets forming on north side of roofs lining with a few drops falling down) to be expected on damn/cold spells like this? - Could the damp entering the roof from around the chimney be causing (some of) it? -...

The foil covering is there to keep the inert gas in, that provides an improved level of insulation for roughly 15 years, then it gradually disappears, and reverts to type.

[/url] Polystyrene degrades in sunlight or at a temperature above 74C. It melts at 240C. It is inflammable and is often glued to sheet plasterboard, which provides fire protection and a hard surface suitable for a skim coat plaster. Plasterboard provides a 30 minute fire wall.

The roofs in our village are interesting. You can never tell if they are insulated or not. Mine are the last to loose our snow- but then, we have 8 inches of polyurethane and polystyrene in our ceilings. A roof covered with snow, may have very good insulation, or little or no heating, it may...

While prior to the 1970's oil shortages that was true. Since then we have had the IPEC agreement where lower oil use results in higher costs. And our Power companies are working to the same principal, use less pay more. Adding ventilation to a roof increases heating and cooling costs...

Sorry, you miss the point of it all! It is because the air is warmer than the roof, that it holds water vapour. But, on contact with the roof, the air cools and has to drop its excess water vapour; ie ;Condensation. Heating the air, will enable it to hold more water vapour, but the water...

Your priority is draft proofing; Keep in mind that the wind forms an area of low pressure to the lee, and above a building, and the air will mainly be sucked out of that side. The wind is pulling your warm air mostly from higher holes, and that warm air is being replaced by cold pulled in...

You have put one hell of a lot of water into your home, probably at a time when you have been keeping the windows closed to keep warm. Gradually that concrete and plaster has been (and will be for some months) drying into the air. Concrete dries at a rate of about one millimeter a day at a...

The condensation in the loft, will be the result of water vapour rising from your home and condensing on the cold roof. This is normal. Runs of water down the side of the chimney are almost certainly down to leaking flashing. It may be that old lead flashing has moved or cracked - it may be a...

Vibration doesn't work like that. Again think of a drum, noise doesn't come out of the solid sides, only the skin vibrates.
