Description

With fuel prices rising all the time, it is becoming increasingly expensive to meet basic human need for heating. This has been the case particularly in the UK where energy prices have seen unprecedented rises in the past year. Added to that, the UK has the oldest and least energy efficient houses in Western Europe. The extent of this inefficient building stock means that we have to do more than just built new energy-efficient houses. We need to retro-fit our existing stock.

Matilda’s Blanket is a unique internal wall insulation system that stops old, solid wall homes from leaking heat. Usually about 45% of heat is lost through solid walls in houses. Matilda’s Blanket reduces this substantially through an easy installation process that takes a two-person team one day to complete.

First, the electrical fittings and radiators are removed and replaced with a plug-and-play system. A self-adhesive vapour control membrane is applied to the wall, which creates an airtight seal. Next the blanket panels are installed next to the membrane and sealed in a robust and smooth way so that the wall looks and can be decourated just as it was before. This “blanket” takes up 81mm of space and has saved most residents 30-40% on their annual energy bills.

Objectives and beneficiaries

To keep homes warm, save money and improve energy efficiency.

Strong points of the practice

• Keeps houses warm and saves money on energy bills at same time.
• Completed with minimal disruption to residents.
• Increases the stock value of the property.
• Comes with an insurance backed by a 25 year guarantee.
• The material is 10 times stronger than a plasterboard solution.
• Does not alter the external appearance of the property.
• Can work as part of a hybrid system with external insulation on the rear of properties.
• It can be applied to all housing types.

Expected results and benefits for climate change adaptation and mitigation

This project aims to address the problem of fuel poverty in the UK with a simple solution that is of minimal effort for property owners. This will simultaneously achieve the organisation’s goals of reducing negative environmental impacts in the UK.

Replicability potential of the practice

The project can be implemented in any household with solid walls (i.e. of brick or a similar material). The materials and skills are transferable.
