Condensation In Loft After Insulating: How To Fix It

Condensation in loft after insulating

Attics and lofts are often neglected space which could be far better utilised – if they were not so damp. Even condensation in lofts after insulating sometimes means that the area is not usable.

Lofts and attics are prone to dampness and air leaks, which all lead to condensation, making it completely unsuitable to even store things in.

The great thing about using a spray foam to insulate the attic or loft is that it can mean adding extra space to your home, and extra value to your property.

What used to be a damp area dripping with condensation, can be transformed into a cosy, comfortable room, that’s habitable all year round. If your loft insulation installation is carried out correctly, there should be no condensation whatsoever.

With this in mind, we explore the challenges of condensation in greater detail, and offer some savvy solutions to keep your loft functioning effectively for many more years to come…

Condensation in Loft After Insulating: Key Causes

Many old methods of insulation meant that floors in the loft were insulated, and the top of the room left without any insulation in place. If this is done, the house will be warm, but the attic will be cold, with numerous air leaks, causing condensation.

If you want your home to be warm, and your loft to be free of condensation, then it is important that the insulation is applied right at the roof level.

Condensation in lofts after insulation will eventually affect the roof by rotting the timers, and impairing their structural integrity. You may be looking at replacing the entire roof if the condensation in the loft after insulation is not taken care of soon enough.

How Spray Foam Solves the Problem

Many older houses were built with roofing felt which is impermeable to water, so no moisture is able to escape. That is why you may find mould on the ceilings in these houses, even after the house has been insulated. Optimal temperature is important for this project.

By using a spray foam to insulate your loft, the build-up of moisture is eliminated from the roof area. Spray foam insulation also protects properties against mould. Consequently, the threat of respiratory diseases is significantly reduced.

Once completed, there should be no condensation in the loft, after insulation is installed. Spray foam insulation will benefit you in many ways, one of them being to reduce your energy costs.

Taking into account that more than 50% of heat is lost though inadequate, or no loft insulation, it makes sense to carry this out as soon as you can!

How Does Loft Insulation Help?

We all know that hot air rises. If the insulation only warms your house, then hot air will eventually meet cold air in the loft, because the loft is insufficiently sealed. Hot and cold mean dampness, and then inevitably condensation.

To prevent condensation in lofts after insulating, you should make sure that you have a reliable company carry out the work. Never go for a ‘budget’ company, as they will deliver substandard materials, which will mean extra problems for you in the future.

Whether you are thinking of replacing loft insulation in an older house, or applying it in a newer home, our experts will guide you through the whole process, and make sure that the work carried out is exactly what you expect.

Without good barriers in place, your home can easily become a hotbed of damp and condensation problems, and cost you lots of money in the future. Having spray foam applied is the best way to counter condensation in lofts after insulation.

Condensation in Loft After Insulating: Top Tips and Tricks

  • Increase ventilation in the loft. It is a good idea to have a window which opens in the loft, after you have had the area insulated.
  • Consider reducing moisture in the lower rooms of the house with better extraction methods.
  • Make sure that the bathroom extractor fan is not venting into the loft, as this will only increase condensation.
  • If you have a cold-water tank in the loft, then be sure to cover it so that no evaporation occurs.
  • Make sure that kitchen extractor fans blow outside, and not into, your loft. Check out some energy saving tactics to use in your kitchen.

Condensation in lofts after insulation can occur in businesses as well as homes, so be sure to check frequently for this, and consider having your loft insulated with a good quality spray foam.

Once your loft is condensation free, you should check out some methods of keeping the area dry and ambient for good.
