Loft insulation in Minstead

The first thickness goes down between the joists and finishes level with the timber. On its own that is only half a job, because every joist is then a strip of cold running the full width of the ceiling.

The second thickness is laid across them at right angles, the joists disappear underneath it, and the pair come to roughly 270mm. That is the depth Approved Document L expects of a loft being renovated, and the reason for it is a lower U value across the ceiling. More heat loss goes that way than any other, which is why you feel it in the rooms and see it on the heating bill long before an EPC catches up.

What goes down depends on the Minstead roof. Rolls of mineral wool, glass wool or rockwool, cover open ground. Batts suit a roof cut into small bays. Loose fill is what gets into a shallow pitch, and sheep wool suits anyone who would sooner keep mineral fibre out of the house. Rigid board such as PIR or Celotex belongs at rafter level rather than on a floor. So does taped vapour control, and so does multi-foil quilt, which is what you reach for when a sloping ceiling or a dormer cheek cannot give up any depth at all.

Then the eaves, which is where the care goes. The wool finishes on the wall plate and the strip of air above it is not touched, because that is how the roof takes its air. Vent trays hold it open. Cross ventilation begins at the eaves, travels the slope and escapes under the ridge, and a ridge vent gives it a wider door. A breathable membrane offers another way out. Bitumen felt underlay offers none at all. Warm the ceiling and the dew point rises with it, so a loft that coped for decades can show condensation, wet material and black mould on the timbers in one winter once the edges are packed.

Anything already in a Minstead loft is looked at before it is buried. Thin where it has settled, crushed and compressed under boarding, patchy round old wiring, contaminated with droppings or simply missing at the wall, and it goes into bags at the hatch and comes out with us rather than sealing interstitial damp into the middle of the build up. Access is that hatch and nothing else, so crawl boards go down first, nobody trusts a lath and plaster ceiling, and the ladder work counts from the first rung.

What is left is the things that live in a loft. The cold water tank is lagged and so is its pipework, because the space above your ceiling is colder the day after than the day before. Wiring and cables go on top of the insulation rather than under it. Fire rated covers go over recessed lights and downlighters. If the loft is used, the boarding is put back on legs at a height that leaves the depth untouched, the loft ladder is reset to reach the platform, and the hatch is finished with rigid board and a draught seal.

Roof construction decides how the day goes. A cut roof, made on site from rafters and purlins, gives head room to work in and often has no underlay at all behind the tiles, so it breathes well and lets the wind through, and material has to be fixed rather than simply unrolled. A trussed roof gives none of that: it is a lattice of braced timbers, everything is fed in from the hatch, and the corners are reached one length at a time. Either way we would rather tell you at the quote which of the two you have than surprise you with it on the day.

No Minstead loft is priced per square metre. The open middle of a loft is quick; the edges take the time. Getting in. A cottage where the hatch is a small trap in a cupboard, a loft you can stand up in, and a chalet with rooms already in the roof sit at very different points on the price. A hatch over a stairwell, or a crawl space crossed on your knees, adds hours before any material is laid.

What has to move. Old material to bag and remove, stored boxes to shift and put back, and boarding to lift or raise on loft legs so the insulation is not squashed all cost time.

The roof structure. Joists at regular centres with a clear run across them are straightforward. A trussed roof full of bracing, or an old cut roof with uneven joists, is slower.

Ventilation and the edges. Insulation stops short at the wall plate so the eaves stay open, or a warm bedroom becomes a wet roof. In a damp, shaded setting under trees that ventilation matters even more. Depth into the corners, round the hatch and over downlighters is most of the labour, and Approved Document L sets the depth the work should reach.

Ask any other quote what depth is being laid and in how many layers, whether the old material comes out, and whether the hatch is insulated and draught-stripped.
