Just how Green is your home?

When you buy applianaces these days they have and energy rating from A to G indicating how efficient the appliance will be from an energy usage point of view.
The less energy, the less the cost of running it.

The same applies to homes and commercial buildings.

If you have an EPC (Energy Performance Certificate) it will show how energy efficient the premises are, thus also telling you if you are saving or wasting money.

Having your premises insulated with NS Insulations not only is often free of costs due to the governments grants, but its a smart move too on your part.

If you insulate the walls for instance you’re less likely to heat the street and more likely to see savings in your annual running costs.

We do make holes to fill your cavity walls, but …

When we carry out a survey to give your home the much needed cavity wall insulation, we’ll first survey the brick work.

We’re looking for loose render, loose mortar joints and anywhere that water can ingress.

The last thing we want is for you to complain of damp because water can get in. Anyway having ensured that the walls are in good condition we drill holes as shown in the attached image to ensure that the cavity wall is totally filled so that you don’t have any cold spots.

The holes are really neat and we even mix mortar with chemicals to get a near perfect match so that you’ll barely see them.

So unless you have a brand new home where the cavity is already filled with insulation there is no other way to make your home warm.

But we respect our customers home and our trained staff ensure that you fully understand everything about the installation process before we go ahead.

Don’t worry though we’ll look after your home.

Does cavity wall cause damp inside a property?

Not if its installed correctly!

You’ve probably heard of nightmare stories where cavity wall insulation has been installed and the occupants are up in arms over damp and cold coming into their homes.

You’ve probably heard too that when a house is built it generally has a cavity between the internal and external walls.

So let us explain the causes and various type of damp in houses.

Rising damp is caused when the membrane just above the foundations, at the bottom of the room walls is breached. Once the moisture starts to get into the walls, they become damp and the plaster becomes wet.

The outside walls of a brick house are pointed between bricks with cement. When the mortar between the bricks drys out and comes out, driving rain that hits the walls penetrates through the walls. Its the cavity that actually stops this coming into the house.

Occasionally the cavity is full of debris and it is this that passes the damp from the external wall to the internal one.

Generally if you see damp in a home, check to see if the walls are sodden, the plaster soft and coming away from the wall. If it is this will likely be rising damp, but if the damp is on the inside surface of the walls only and the plaster is generally dry, then the issue is caused by condensation.

So armed with this knowledge you’ll now be able to understand why damp ends up in the home and what to consider when having cavity wall insulation.

So to start with you must ensure the external bricks are well pointed, no gaps in between the bricks for moisture to get through.

When My Energy Grants turns up at your home the very first thing they will do is to check the pointing of your house. This has to be perfect before cavity wall insulation can be installed.

There are stories that we hear of property owners saying that as a result of cavity wall insulation, instead of keeping the cold out they had damp coming in. But if you have poor rendering or pointing on the outside of the property this will cause the penetrating water to soak into certain types of wall insulation like rock wall and then like a sponge penetrate the entire internal walls.

Most property owners that experience damp issues are surprised to find that actually its condensation that is causing the internal damp. The cause of condensation is moisture in the air. The simple truth is that by opening windows, using vents and ensuring a flow of air properties can and do avoid damp.

So remember this, if you’re considering having cavity wall insulation installed by My Energy Grants, if you’re rendering or pointing is not up to scratch, we’ll not install the cavity wall in your home until its sorted. But don’t worry we can help sort it for you if needed. YOu’ll also need to commit to opening windows occasionally using vents after showers, allowing the air to flow around your home in order to not have condensation. Finally if the walls have signs of damp, we’ll check if your damp proof membrane or if the cavity walls are clear first with cameras before we start any work.

So when you next get told that cavity walls causes damp, you’ll now be better informed and tell others about My Energy Grants!

Stone wall insulation

Some homeowners have previously been told that their home may not be suitable for traditional cavity wall insulation due to the make-up of the walls.

We are able to recommend a specialist product called Technitherm which can be used to ensure your home receives the same benefits as those installing traditional cavity wall insulation.

National Surveys

Nationals Surveys specialise in domestic and commercial Energy Performance Certificates (EPCs), Legionella Risk Assessments, Display Energy Certificates (DECs), floor plans and landlord inventories.

Cavity wall insulation

The external wall of a house is usually made of two layers with a void in the centre, known as a cavity wall.

Filling the space between the two walls with insulation material is an effective way to prevent the loss of up to 35% of your home’s heat.

Room in Roof Insulation

Room in Roof Insulation

Room in Roof Insulation grants are available to everyone. As long as the property is suitable, you should qualify for a 100% grant to have the rooms insulated.

Loft Insulation

Loft insulation is one of the most effective and common insulation solutions. Around 25% of a home?s heat is lost through the roof of an un-insulated property; therefore it’s advisable to get a good layer of insulation installed.
