Insulation - Loft
Loft insulation can help you save money due to heat rising it can be very effective and save up to 20% of energy bills.
When insulating a loft, a depth of at least 150mm (6inches) is recommended. In many older properties, shallow joists in lofts restrict depth for loose-fill insulation. The most common type of insulation is blanket insulation this is using glass fibre, mineral fibre blanket, foil-backed felt and rock fibre. Another type is granular and loose fill fibre these are best not used in a draughty loft because the fibres may blow about in high winds. these are some forms of loose fill fibres; Cork granules, exfoliated vermiculite, mineral wool or cellulose fibre. Sheets of loft insulation are a good option if you intend to use the attic area, Only thin sheets are required especially if the finish is covered with plasterboard.

Open Question: Unfinished cavity wall insulation!?
I am part of a block of four flats and we decided to have cavity wall insulation so called up a surveyor to take a look. At first it seemed to him we already had it installed, but on further inspection he found the other three walls were empty! Therefore we have one wall partially insulated wall (possibly a DIY job?) and the company said because of that they can't do the rest of the walls. The surveyor seemed to think that there was nothing we can do to remedy this, does anyway have any advice please?
Open Question: I am considering cavity wall insulation. I know the pros are there any cons I should consider?
Cavity fill insulation (post construction) is a good way of reducing heat loss but does it cause problems like condensation?
Open Question: expanded polystyrene packaging as insulation?
Can you use expanded polystyrene packaging as insulation in your loft? I'm thinking about using it in addition to the existing rolls of insulation between the joists. Is there anything I should know? Is it fire safe for example?
Open Question: Insulating under a bath.?
Right, what with scary gas and electric prices here in the UK I'm on an eco-mission!
My bathroom is on the first floor - downstairs underneath it is the back hallway which leads to the garden. We have a large corner bath and the floor under the bath are old wooden floor boards which are a bit gappy and at times you can really feel a breeze gusting through (the remainder of the bathroom floor is tiled). The fact the bath is huge means if you have a bath, the hot water goes cold in record time!
I was wondering if it is possible to put insulation around the bath - obviously I need to leave some gaps to allow air to circulate.
Any builders out there who can tell me if this is actually worth doing on a cost basis AND would I be at risk of causing damp problems with the floorboards under the bath?
Many thanks!
Open Question: Advice regarding attic conversion?
I am currently living in a house which as had its attic converted by a previos owner. As it's getting colder I've noticed that the attic is getting colder. Am I right in assuming that it's been built using little or no roof insulation? Is there an easy way to rectify this, short of taking down the ceiling and starting again?
