Why choose energy saving masonry paint from SecoTherm

Home insulation is a great way to save money on your heating bills; locking the warmth inside your home so you can reduce your energy consumption. It’s also great for the environment, as this means you’re reducing your carbon footprint too.

While the benefits of home insulation are numerous, it can be confusing to decide what type of insulation type to choose. Cavity wall insulation, loft insulation, double-glazing and draft-proofing are all popular options. However, a new and innovative product has recently been grabbing headlines in the insulation industry, in the form of insulating masonry paint.

How does Masonry Paint work?

Energy-saving masonry paint works by keeping your home’s exterior dry, which prevents heat escaping through brickwork and improves its thermal efficiency. SecoTHERM, a leading brand of masonry paint, points out that wet bricks convey heat 2.5 times faster than dry bricks, meaning around a third of heat can be lost through a home’s walls.

Porous building materials, such as stone and brickwork, contain numerous air-filled cavities which provide good insulation properties. This only works when the materials are dry however. Wet materials increase the transfer of heat dramatically, which you’ll notice if you’ve ever tried to remove something from the oven with a wet oven glove.

Masonry paint creates a thermal barrier to slow the escape of heat. It’s a transparent product which chemically bonds to the exterior of a building, repelling water from soaking in, and preventing dirt, mould and discolouration from taking hold.

The benefits of WALL COATINGS

The benefits of masonry paint for wall coatings are both practical and cosmetic. From an energy standpoint, it improves the thermal efficiency of masonry by keeping it dry, which in turn can lower your energy bill. If you already have existing insulation, such as cavity wall insulation, it will work alongside this to maintain and strengthen its thermal properties.

As well as reducing heat loss, it can help your home appear cleaner and fresher, by slowing the aging of your brickwork. By making exteriors less susceptible to micro-organisms, algal bloom, and dirt taking hold in the first place, it turns walls into self-cleaning surfaces that need little to no upkeep. It also protects from UV degradation, so your home is protected all year round.

The downside of Masonry Paint

Due to the materials required to produce this treatment, the costs of masonry paint, as you may expect, are a little more than your average exterior paint. When you factor in the money-saving benefits however, it’s certainly beneficial in the long run.

Another downside of this new product is that there are several brands of masonry paint vying for your attention, and it can be difficult to know which to choose. When selecting a masonry paint, be sure to opt for a reputable brand. SecoTHERM has been tested by the Danish Technological Institute, who conducted thermal conductivity experiments on its effectiveness. Comparing a standard wet brick to a SecoTHERM treated brick, they concluded that the product can save up to 30% of heat escape.


For best results, always use a trained professional to apply wall coatings to your property, to ensure the most efficient results from full and even coverage. Furthermore, it’s worth noting that SecoTHERM comes with a 20 year guarantee when installed by an approved applicator.
