Flat Roof Insulation
Flat Roof Insulation
Flat roof insulation is an effective way to improve comfort, reduce energy consumption, and extend the lifespan of your roof. AEG Construction provides professionally designed and installed flat roof insulation solutions that help keep rooms warmer in winter, cooler in summer, and cheaper to run all year round.
Whether you are upgrading an existing roof or planning a replacement, insulating your flat roof delivers long-term energy efficiency, enhanced protection, and improved property performance.
What Is Flat Roof Insulation?
Flat roof insulation involves installing high-performance insulation materials within the roof structure to limit heat transfer between the building and the outside environment, preventing energy waste.
By creating a continuous thermal layer, flat roof insulation improves temperature stability inside the property and reduces the amount of heat lost through the roof while protecting against moisture penetration and condensation damage.
Insulating Existing Flat Roofs
Adding insulation to an existing flat roof typically involves removing and replacing parts of the roof structure and weatherproof covering. This allows insulation and a new high-performance weatherproof layer to be installed correctly, ensuring long-term effectiveness.
Flat roof insulation is often carried out when a roof covering is nearing the end of its lifespan or showing signs of leaks, damage, or deterioration. However, insulation can be added at any time, and combining both works can prevent future issues while maximizing investment value.
Building Regulations & Performance Standards
Flat roof insulation must meet UK Building Regulations Part L requirements for thermal performance. Current guidance sets a target U-value of approximately 0.18 W/m²K or better for new or replacement flat roofs.
AEG Construction designs and installs systems that meet or exceed regulatory requirements, ensuring compliance, long-term performance, energy efficiency, and protection for your property investment throughout its lifespan.
