Internal Wall Insulation
Suitable for various buildings, including housing associations, local authorities, education, healthcare, and public buildings.
Discover our Premium System: Engineered with the same design principal as our safeguard system, our premium system consists of an EPS insulation core bonded between gypsum fibre boards. Secured in a light gauge steel frame with vertical and horizontal compression, it’s mechanically fixed to floors, ceilings, and supporting walls aligned with a breather membrane to ensure moisture control and structural integrity.
Features and benefits:
Thermally efficient
Insulated panels minimise heat loss and reduce energy consumption.
Fire Performance
Safeguard system is classified as European Classification B-s1-d0.
High airtightness performance
Decrease air changes per hour to as low as 3 ACH.
Moisture control
Mitigates risk of surface and interstitial condensation.
Non-invasive
Modular systems arrive on site cut to size, minimising disruption to tenants.
Prefinished
Removing the need for wet trades.
Robust & durable
Tested with multiple fixings and loads, therefore no need for secondary supports.
MMC
Quality of offsite manufacture, combined with approved installation teams, removes the risk of build defects.
Certified
The only fully approved end-end Internal Wall Insulation Systems available.
