Loft insulation in Kinson

The top-up comes first. An early post-war Kinson loft usually holds a grey, flattened layer, missing wherever cables were run or someone crawled over to the tank. Anything wet from an old leak or contaminated with droppings is bagged and taken down; what is sound is evened out and kept.

Glass wool or Rockwool roll then fills between the ceiling joists, and a second roll crosses them at right angles, so the timbers stop acting as a cold bridge every 400mm. That takes the ceiling to the 0.16 U-value Approved Document L expects when a roof is upgraded, with loose fill or batts round the struts where a roll will not go, and sheep wool if you would rather have a natural fibre. It is one of the cheaper ways to lift an EPC, and most semis take a day.

Bungalows. In a Kinson bungalow the loft covers the whole house, so it is the biggest saving on the heating bill. It is also the hardest to get right at the edges, where the rafters come down low over the wall plate. That is where insulation gets pushed in until it blocks the air gap under the felt. We fit a vent tray in each bay first, then take the full depth out to the wall so the edge of every room is covered and the roof still has cross ventilation. An insulated loft runs colder, so without that airflow the dew point sits on the underside of the felt. A long bungalow loft can take a second day.

Storage. In a cut roof the ceiling joists were sized for a ceiling, not a floor. So storage goes on a small raised platform on loft legs near the hatch, above the full depth, rather than boarding across the whole loft. The hatch is insulated and a loft ladder fitted if you want one.

Owners, tenants and flats. Much of Kinson was built by the old Bournemouth council, and plenty of those houses have since been bought and sold on. If you own yours, you instruct the work. If you rent from BCP Council, the loft is theirs to insulate, so report it to them rather than booking a builder. In a flat, the roof space belongs to the freeholder, and a job for the whole block comes through the managing agent. On a semi, the party wall in the loft is checked too, so heat and smoke cannot pass over the top of it to next door.

Cables, tank and lights. Cables are lifted to sit on top rather than buried, recessed downlighters get proper covers, and the tank and pipework left in the cold are lagged.

Rooms in the roof. Some bungalows in Kinson have had a room put in with a dormer. The sloping ceiling is insulated at the rafters with PIR rigid board such as Celotex, keeping an air gap under the felt or underlay, with a vapour control layer inside, aiming at 0.18. A multi-foil helps where headroom is short.

When we would say wait. Black mould on a bungalow ceiling that comes from a bathroom with no extract fan will not stop because the loft is deeper. The fan goes in first.

No rate per square metre, because the floor area is the easy part and the awkward edges are where the time goes.

Getting to it. A bungalow with a long, low loft and eaves all the way round, a semi with the hatch over the stairs, and an end terrace with a boarded loft full of boxes all price differently. A hatch on a landing you can stand a ladder under is one job. A hatch over a stairwell, a crawl space you can only move through on your knees, or a loft full of boarding that has to come up and go back, is time before any material is laid.

What is up there now, and what it is sitting on. Old material that has to come out, be bagged and taken away is a cost before anything new goes down, and so is a loft full of boxes that has to be emptied and put back. Joists at 400 centres with a flat run across them is a different afternoon from a trussed roof full of bracing.

Ventilation, and the edges nobody reaches. Insulation stops at the wall plate and the eaves have to stay clear, or you trade a warm bedroom for a wet roof. Getting depth right into the corners and around the hatch, boxing over downlighters and lagging anything that now sits in the cold, is most of the labour. Approved Document L sets what the work is expected to reach.

Comparing quotes? Ask what depth is actually being laid and in how many layers, whether the old material is coming out or being covered over, whether the eaves are being kept clear, what happens to anything you store up there, and whether the hatch and the pipework are included.

Most repairs in Kinson need no application at all. What decides whether a change to the outside of your house does is who the council is, whether a conservation area or a listing applies, and whether the place sits in a protected landscape.
