Everything you need to know about replacing conservatory roofs or building new extensions with hup! and Modglaze.
hup! is an advanced, timberless extension and conversion system manufactured off-site using high-performance structural insulated panels. It allows Modglaze to construct extensions and conservatory conversions up to five times faster than traditional building methods.
Yes, completely. The hup! system meets and exceeds current UK Building Regulations, delivering exceptional thermal performance with U-values as low as 0.17 W/m²K.
In most cases, yes. Because hup! wall technology is lightweight yet structurally strong, it can frequently be built onto existing foundations, saving substantial installation time and excavation costs. *Subject to survey, structural suitability and any required Building Control approval.
Because every component is pre-machined off-site to exact technical measurements, the watertight shell of a hup! extension or conversion can usually be erected on-site in just a few days.
Modglaze provides full supply and installation services for hup! systems across Gloucester, Cirencester, Cheltenham, Evesham, Worcester, and Ledbury.
hup! walls can be customised with a wide range of finishes including brick mesh, genuine brick slips, render boards, modern timber or composite cladding, and aluminium trim detailing.
