Loft Insulation Top-Up in Heaton Moor (200mm Knauf Upgrade + Lap Vents)

With temperatures dropping fast, loft insulation becomes one of the highest-ROI home improvements a family can make.

Today’s job in Heaton Moor was a perfect example of a quick, clean upgrade that makes an immediate difference.

The homeowner already had a solid 100mm insulation base layer in place.

Our job was to add a 200mm Knauf top-up and install lap vents to help reduce condensation build-up.

What We Found on Arrival

The existing insulation:

• was not the old yellow fibreglass

• had no patchy cold spots

• was evenly installed

• provided a solid 100mm base

No removal was needed.
No waste or disposal costs.
Just a straightforward top-up install.

What We Did

1. Installed 200mm Knauf Top-Up Insulation

We laid fresh 200mm Knauf roll insulation across the entire loft to bring the total depth to approx 300mm (the recommended modern level for UK homes).

This directly improves:

• heat retention

• boiler efficiency

• running costs

• overall comfort in winter

Today was one of the coldest days so far this year — perfect timing to benefit from the upgrade immediately.

2. Installed Lap Vents for Condensation Control

Most modern homes trap moisture in the loft from:

• showers

• cooking

• drying clothes

• general house humidity

Without ventilation, this leads to mould on rafters and dark patches on membranes.

We installed lap vents between the felt layers to allow airflow to escape rather than sit in the loft.

This prevents:

• mould growth

• damp odour

• timber damage

• long-term insulation failure

Customer Reaction

The homeowner was extremely happy with:

• the speed

• the clean install

• the immediate warmth difference

• and the fact that this will reduce energy bills going into winter

They also said they’ll likely book us again for boarding in the new year.

Duration
