Insulating Creme

Rejuva Insulating Creme

Rejuva® Insulation Creme has been developed with superior technology. It will create an invisible insulation barrier, penetrating deep into the substrate, up to 17 mm and protecting the masonry for over 20 years. It will protect your walls and its cavity from penetrating damp, improve thermal resistance and reduce energy bills. Rejuva Insulation Creme makes walls and bricks self cleaning and allows the walls to breathe naturally

Super hydrophobic

The excellent hydrophobic properties will make your masonry dry and extremely resistant to biological hazards, mould, mildew, etc.

Self cleaning efficiency

Dirt particles are unable to obtain a hold on a masonry coated with Rejuva and will simply flow off with rainfall.


Your masonry will remain clean and attractive for many years.


The masonry is able to breathe and will be permeable to water vapour.


Highlights and properties

How to apply Rejuva® Insulating Creme

After suitable preparation and treatment with Rejuva cleaner and when the facade is dry  apply one full coat of Rejuva Insulation creme to the facade . Application may be by low pressure pump or airless spray.

Properties and characteristics

Proven performance

Rejuva® Insulation Creme has been tested and certified to ISO standard. The product penetrates deeply into the substrate, creating an invisible insulation barrier that reduces water absorption by more than 95%. REJUVA ® Insulation Creme has been tested according to EN ISO 15148:2002, demonstrating its hygrothermal performance on concrete, mortar, brick, and sandstone.

Damp walls = Thermal bridges

If the pores of a wall collect moisture, more heat is transferred than it would be possible if the cavities were filled with air. In conclusion, the thermal conductivity of the wall decreases enormously with dampness. Tests have shown that a damp content of 5% in a plain brick wall, for example, can lower the insulation performance by up to 50%, especially where cavity wall insulation has been installed. Consider that porous building materials, such as natural stone, brick and solid brick, to name a few, normally have good insulating properties. They have air-filled cavities, which offer low thermal conductivity. BUT ONLY WHEN THEY ARE DRY!


The masonry is able to breathe and will be permeable to water vapour whilst allowing air and moisture to pass through from one side to the other. A breathing masonry will improve the thermal conductivity and insulation properties. Consider that just a 5% content of damp in cavity wall insulation or other building materials can lower the thermal resistance by up to 50%.

Self cleaning efficiency

Dirt particles are unable to obtain a hold on the Rejuva® treated brickwork and will therefore simply flow off with rainfall. The masonry remains clean and attractive. Even on sides which are particularly exposed to the weather like on the north-facing side or areas in shade, as well as in areas with high air humidity or sea salt penetrated air.

Masonry insulation barrier

Rejuva® Insulation creme keeps your brickwork dry

If humidity can access into the cavity wall insulation, its insulating properties will be damaged. A masonry treated with Rejuva® Creme will be colour stable for many years. In conclusion, the façade will keep its beautiful appearance as when it was new. A treated surface will have super hydrophobic capabilities. It will not get dirty thanks to its self-cleaning properties. Therefore, dirt particles and dust will easily be washed off with rain.

Invisible insulation barrier for energy savings

Rejuva Insulation creme penetrates deeply into brickwork and forms a reaction with the mineral groups behind the surface to inject invisible insulation into the masonry.This will help to create a dry building as moisture can easily escape and breathe out. Thermal conductivity will slow down as a result and less energy will be needed.

Clear treatment for most masonry substrates

Rejuva Insulation creme ® can be used on all absorbent mineral surfaces. Clean all areas with a high pressure washer and allow to dry. Apply Rejuva cleaner to all areas and allow to dry.

Rejuva Insulation creme will penetrate into the masonry and leave a super hydrophobic ,self cleaning , breathable surface , there will be no change to the colour or sheen of the treated masonry.
