For 40 years, Modern Plan Insulation Ltd has been installing specialist closed-cell cavity wall foam insulation systems throughout Manchester, Bolton, Lancashire, Liverpool, Cheshire and across the UK.
Our advanced polyurethane foam insulation delivers outstanding thermal performance while completely filling the cavity, eliminating voids, cold spots and air movement that can occur with traditional fibre and bead insulation systems.
Whether you're looking to improve energy efficiency, reduce heating costs, upgrade a property for a heat pump installation or replace failed cavity wall insulation, MPI provides long-term solutions backed by decades of experience.
For larger commercial, industrial and agricultural buildings, our Spray Foam Insulation systems deliver seamless thermal performance and condensation control, our Marine & Buoyancy Foam Applications offer specialist closed-cell foam solutions for marine environments while or Condensation Control provides spray foam insulation solutions to prevent condensation, reduce moisture damage, and protect buildings from mould, corrosion, and deterioration.
Ideal for Hard-to-Treat Properties
Closed-cell cavity wall foam is particularly effective where traditional insulation systems may not perform adequately.
Applications include:
Narrow cavity walls
Older and non-standard construction properties
Random stone and irregular cavity construction
Flood-risk & high-exposure locations
Property upgrades for heat pump installations
Homes affected by failed cavity wall insulation
Why Choose Closed-Cell Cavity Wall Foam?
Unlike traditional insulation materials that can settle, slump or leave gaps over time, our closed-cell foam expands to fill every part of the cavity, creating a continuous thermal and air-tight barrier.
As the foam cures, it bonds to both the inner and outer leaves of the wall, providing additional structural stability while significantly improving thermal performance.
Superior thermal performance
Lower heating and energy costs
Reduced carbon emissions
Eliminates cold spots and voids
Moisture-resistant and highly durable
Suitable for all exposure zones
Structural wall stabilisation benefits
Performance that lasts the life of the building
Failed Cavity Wall Insulation Replacement
MPI are specialists in the removal of failed cavity wall insulation systems.
Where fibre insulation has settled, become damp or created cold spots within the cavity, our specialist extraction and replacement services can restore thermal performance and improve the overall efficiency of the property.
Many of our clients choose to replace failed cavity wall insulation with closed-cell foam to achieve a permanent solution that completely fills the cavity and helps prevent future issues.
Why Heat Pump Installers We Work With Recommend Closed-Cell Cavity Wall Foam
As heat pumps become increasingly popular, improving the thermal performance of a property has never been more important.
Heat pumps operate most efficiently in well-insulated, airtight buildings where heat loss is minimised. Our closed-cell cavity wall foam insulation completely fills the cavity, eliminating cold spots, reducing air movement and creating a continuous thermal barrier throughout the wall structure.
By improving airtightness and reducing heat loss, closed-cell foam helps heat pumps maintain comfortable indoor temperatures more efficiently, reducing energy consumption and improving overall system performance.
For this reason, MPI works closely with heat pump installers throughout the North of England, helping homeowners create warmer, more energy-efficient homes that are ready for low-carbon heating technologies.
Why Choose MPI?
With over 40 years of insulation experience installing cavity wall foam systems, MPI is one of the UK's most experienced specialist cavity wall insulation contractors.
From difficult-to-treat properties and historic buildings to modern homes and heat pump upgrades, we deliver proven solutions that improve comfort, reduce energy consumption and protect buildings for the long term.
