Loft Insulation in Sarn

Estate homes and older terraces around Sarn

A large share of homes in and around Sarn are semis, short terraces and bungalows from the second half of the twentieth century, alongside more recent private estates. Their roofs are mostly simple, with a hatch over the landing and an open loft floor. The usual finds are mineral wool laid at 100mm or less decades ago, gaps where electricians have pulled it aside, and loose boards nailed straight onto the joists that have flattened whatever was beneath.

The older terraced rows along the roads through Aberkenfig, Tondu and Brynmenyn date back to the coal and ironworking years at the mouth of the valleys. These have smaller, older lofts with stone gable walls, and they need more care around the eaves, where draughts and damp tend to get in.

What Sarn homes usually need

Loft Insulation in Sarn

Open estate lofts around Sarn are ideal for a Knauf Earthwool top-up to 270mm, laid across the joists in a second layer so there are no cold gaps.

Loft Boarding in Sarn

Plenty of family homes here use the loft for storage, and raised boards on loft legs give that space without crushing the insulation.

Rodent Proofing in Sarn

Homes backing onto fields and the riverbanks around Sarn see mice looking for a way in as the weather cools, so we seal the gaps and replace any fouled insulation.

Getting the most from a Sarn loft

Because so many homes here rely on the loft for storage, the most common mistake we see is chipboard fixed straight onto the joists with only a thin layer of insulation below. Our guide to boarding a loft without crushing the insulation explains why that matters and what the alternative looks like.

Parking is generally easier here than in the valley terraces further north, which helps on the day. With the hills of the Garw and Ogmore valleys just behind the village, the older terraces still take plenty of rain, so we check gable ends and eaves for damp before laying anything new.
