Iso-Therm Membrane & Black Mould
Iso-Therm: Ultra-Thin Internal Wall Insulation
Stop Heat Loss, Eliminate Damp, and Banish Mould—Without Losing Your Living Space
Are your solid internal walls cold to the touch? Are you constantly battling surface mould, condensation, or peeling wallpaper? Traditional internal wall insulation often means losing valuable floor space and undergoing heavy, disruptive building work.
There is a better, smarter way. At Crystal Damp Proofing & Basements Ltd, we install Iso-Therm, an innovative, ultra-thin thermal insulation system. Supported by premium Mapei adhesives and breathable coatings, this revolutionary system warms your walls, saves energy, and completely blocks damp all at just a fraction of the thickness of traditional insulation.
How Iso-Therm Works
Iso-Therm is a patented, specially woven polyester-based membrane that measures an incredible 4mm in thickness.
When secured with specialized thermal adhesives and finished with a standard plaster skim, the entire system measures just 10mm deep. Because it is so uniquely thin and flexible, it is minimally invasive. In most cases, our specialists can install it seamlessly around windows, light switches, and radiators without even needing to remove your existing door architraves or skirting boards!
The Ultimate Dual-Action Defense
Iso-Therm doesn’t just keep your home warm; it actively protects it from moisture damage:
- The intelligent membrane acts as a barrier against moisture ingress while still allowing your masonry to breathe naturally.
- It completely resists lateral damp transfer, stopping harmful ground salts (like nitrates and chlorides) from ruining your decorative plaster or paintwork.
- By keeping the wall surface warm and preventing natural damp transference, Iso-Therm creates an environment where condensation and black mould simply cannot survive.
- Noticeably reduces heat loss, making your home significantly warmer, more comfortable, and cheaper to heat.
A Fast, Clean, and Effective Solution
Because Iso-Therm can be applied directly to sound, plastered walls, our specialists can transform cold, damp rooms in a remarkably short amount of time. Whether you are retrofitting a heritage solid-wall home or upgrading a cold commercial property, this system delivers maximum thermal efficiency with zero hassle.
