hup! building system - engineered before it reaches site

At the heart of hup! technology, patented wall panels combine timber, steel and insulation into a single manufactured component. Together, these elements form the hup! building system, bringing the work traditionally split across several separate trades into one advanced construction solution.

How does the hup! building system reduce build time?

The hup! building system is manufactured off site under controlled factory conditions, so much of the work is completed before it reaches the property. This removes many of the weather-related delays that slow a traditional build across any of the five towns Park Lane Windows covers.

Is the hup! system more sustainable than traditional building?

Yes, manufacturing hup! walls off site is 60% more carbon efficient than brick, produces zero waste in production and on site, and follows an ISO 14001 accredited process. This makes it a lower impact option than a standard brick extension.

What certification does hup! technology hold?

hup! technology holds BBA approval, an independent certification of performance and durability. Combined with the 60-year lifespan of Ultrapanel technology, this gives homeowners across the region a recognised, assessed standard rather than an unproven building method.
