Addressing Heat Loss in Wall Cavities
Cavity WallCavity wall insulation (CWI) is a measure of energy efficiency that involves injecting the space (cavity) between the inner and outer layers of exterior walls of a home with an insulating material. This hollow, which was originally formed in order that the dampness might not bridge to the inner wall, may be an important cause of heat loss when left empty and thus allowing cold air to move around and through the building fabric. CWI is a highly effective thermal break, filling this hole and creating a highly effective thermal barrier, trapping heat in the home, leading to a drastic increase in the energy performance of the property, a corresponding increase in interior comfort, and a significant decrease in heating costs. It is especially suitable in homes constructed after 1920s that commonly employ this construction technique.
Virko's Efficient & Non-Intrusive Installation
Our specialty at Virko Easy Retrofit is the professional installation of CWI which radically increases thermal efficiency and reduces energy costs. We are supposed to be less intrusive and efficient. This normally involves drilling pebbly sized holes in the external joints of your house (approximately 22mm in diameter). Through these pores, the certified insulating material, mineral wool fibre, expanded polystyrene beads or, in some cases, urea formaldehyde foam is injected into the cavity using advanced paraphernalia. And finally, after the insulation has been distributed uniformly in the hollow, the holes are carefully filled with matching mortar, producing an almost invisible finish.
Pre-Installation Assessment & Benefits
Cavity WallWe pride ourselves on our pre-installation assessment which ensures your house is suitable to have cavity wall insulation. This will involve the use of apparatus like boroscopes to examine whether there are any prevailing damp issues, the integrity of the cavity as well as whether there are any prevailing blockages. and our professional installers use advanced technology to make sure the cavity is filled uniformly and fully, to avoid cold spots and to maximise thermal efficiency. The benefits of CWI are direct and significant: your home will be noticeably warmer in the winter and cooler in the summer because the insulation will limit heat loss in the winter and heat gain in the summer, and you will save blowing your heating bills – often leading to a payback in a short time. It is a non-disruptive measure that can normally be accomplished in a day or two and it will make indoor environment healthier by reducing the condensation on inside walls.
