Insulation in West Lulworth

Loft depth, done to the edges. Most lofts in West Lulworth have something in them and almost none have enough. We straighten and repair what is down, close the gaps where the runs stop short, fit vent trays along the eaves, then lay eco roll across the joists at right angles, between and over, to a finished depth of about 270mm.

That is the depth behind the 0.16 u-value Approved Document L sets for a renovated roof. Sound old material stays and we lay over it. Anything wet, mouldy or nested in is bagged and leaves with us, on its own line in the quote.

Ventilation, which matters more this close to the sea. The village is under a kilometre from the water and the prevailing weather comes off it, working at the edges of a roof rather than the middle, so eaves here are often already damp before anyone adds insulation. Pack wool into that gap and you have sealed the one path the roof space had, and a cold loft with no airflow grows mould on the underside of the felt. Trays go in first so the airflow the Approved Document F standard expects is kept, and the depth stops at the tray rather than in the gutter line.

Where a West Lulworth bedroom is already tucked into the roof the work is at rafter level: rigid PIR board such as Celotex cut tight between and under the rafters with a ventilation gap kept clear above, a vapour control layer before boarding, and the dormer cheeks and sloping ceilings done to match. Where the head height is already low, a multi-layer foil quilt such as TLX gets you performance without losing another inch. If the roof is thatched, that is a specialist trade and we will say so on the phone.

Houses that stand empty over the winter are common enough around West Lulworth to be worth their own line. An empty house with a well insulated loft is a colder loft, so the tank and every run of pipework above the ceiling gets lagging as part of the job, never as an afterthought, and the hatch gets boarded and draught sealed. If a place is let out or shut up between visits, tell us, because we will do the pipework first and the depth second. Where a wall is solid stone there is no cavity to fill whatever a leaflet says, and the real choice is an internal lining or external wall insulation, on a build-up that breathes rather than one sealed tight.

Which part of the house needs it comes first. A loft top-up is one job. Lining a solid stone wall on the inside is another, and insulating a room in the roof is another again. In a stone cottage that room usually has sloping ceilings, so the work goes between and under the rafters. The survey settles which will make the most difference for the money.

What the building needs. Solid walls and old roofs need breathable materials, which cost more than standard foam board. Using the wrong material on stone traps damp and can rot timbers, which costs far more to put right.

Access and clearing. A small hatch in a cottage bedroom, a boarded loft full of storage, or old insulation to bag and remove all add time before any new material goes in.

Ventilation. Adding insulation without keeping the eaves clear or fitting vents moves condensation into the roof timbers. On a house in damp coastal air we price ventilation as its own line. Approved Document L sets the U-value the work should reach.
