hup! walls for Chester homes: energy efficient, strong and quick to build

hup! walls are engineered for homeowners who want a faster, stronger and more energy-efficient home extension in Chester. With excellent thermal performance, durable construction and a build process that is far quicker than traditional masonry, hup! helps create a warm, comfortable space with less disruption to your home.

The performance advantage of hup! walls

Traditional cavity wall construction in a Chester extension requires a wall build-up of 300mm or more to achieve an acceptable insulation standard. A hup! SIP wall achieves a significantly better U-value in a much slimmer profile, typically around 172mm overall.

That reduction in wall thickness translates directly into additional internal floor space, which matters enormously in the smaller-footprint extensions common on Chester terraces, Saltney semis and the tighter plots found throughout Ellesmere Port and Neston.

Across the full perimeter of an extension, the space recovered from slimmer walls adds up to a genuinely meaningful difference in the comfort and usability of your new room.

Precision-built walls with no cold bridges

The closed-panel construction of hup! walls eliminates the cold bridges inherent in traditional masonry. Mortar joints and structural elements in conventional walls create pathways for heat to escape: in a hup! panel, there are none.

This makes hup! walls genuinely superior to cavity wall construction for thermal continuity, reflected in energy performance certificates across hup! projects installed by Fortress throughout Chester and Cheshire.

For homeowners in Tarporley, Wrexham, Frodsham and across the region, this translates to a warmer, more comfortable extension that maintains its performance for the lifetime of the building.
