First Aid for loft renovation: insulation and damp problems
A loft renovation might seem straightforward at first, but it can come with its fair share of pitfalls – from damp walls to heat loss through the roof. Numerous problems can make the space uncomfortable or even unhealthy. That’s why taking the right steps from the very start of your renovation is essential. In this article, we look at the key points of attention, with tips on how to optimally insulate your loft and effectively tackle persistent moisture problems.
Reduce energy loss by insulating your loft
Good insulation in your loft is essential to prevent heat loss in winter. If your loft is poorly insulated, heat will escape through the roof. This not only increases energy bills but also reduces the comfort of your home.
Quality insulation is a must. Aquaplan offers a range of insulation materials that help you create an efficient thermal barrier between inside and outside.
- IKO enertherm Multi-Fit is the ideal PIR insulation board for windproofing and damp-proofing your loft, wall, floor and ceiling. The boards fit together perfectly thanks to their unique tongue-and-groove click system. There’s no need for an additional vapour barrier. IKO enertherm ALU TG is the same insulation, but purchased in individual boards.
- IKO enertherm MG insulation board is ideal for insulating flat roofs with various substrates: steel, wood, concrete (provided an underlay is used), etc.

Aquaplan tip: Planning to use or live in your loft? Then it’s important to insulate the roof. If you’re not planning to use the loft, it’s smarter to insulate the loft floor so that no heat is lost. IKO enertherm Combi-Floor or IKO enertherm BM are both excellent choices for insulating the floor of your loft. |
Moisture control in the loft
One of the biggest challenges during a loft renovation is keeping moisture under control. Moisture issues can lead to mould growth, timber rot, and an unhealthy indoor climate.
Common moisture problems
- Condensation: Occurs when warm, humid air comes into contact with cold surfaces.
- Leaks: Often caused by damaged roofing or poorly maintained gutters.
- Poor ventilation: Traps humid air, which increases the risk of condensation and mould growth.
To minimise the risk of moisture in your loft, you can apply a number of coatings during your renovation to tackle the problem.
- Wall Protect Sealer: This moisture-repellent coating is ideal for treating damp interior walls before painting or wallpapering. It creates a breathable, colourless waterproof barrier that protects against moisture infiltration and prevents mould and peeling paint.
- Rain Protect Liquid: For exterior walls, Aquaplan offers a breathable, water-repellent coating. It protects unpainted external walls from rain penetration and dirt, without changing the appearance of the wall. It’s ideal for protecting walls from damp conditions and provides long-term protection.
