About us

What is Warmerwall?

WARMERWALL blocks quickly clip together to build the walls of your home, outperforming and as a replacement for bricks (which were invented about 8000BC), concrete blocks or timber.

A typical house which has 200m2 of external wall area takes about 10,200 bricks and another 1,700 concrete blocks but also needs to have insulation added to the cavity (even though this is not what the cavity was originally designed for) together with brick ties and built using mortar joints. The weight of these materials handled comes in at around 55,000kgs plus insulation and mortar.

The same house can be built with just 244 WARMERWALL blocks which when filled with concrete (provided through a pump, no handing) provide a strong pre-insulated wall. The weight of the materials handled is just 1,464kgs.

What is a WARMERWALL Block?

The standard WARMERWALL block is 1200mm (4ft) long by 600mm (2ft) high and 280mm (10inches) from front to back. It is made of two leaves of high density, graphite infused fire-retardant polystyrene each 65mm (2.5inches) thick. The two leaves are held together by steel ties every 150mm (6inches) which can be used to fix cupboards, wall coverings to, without need to drill the concrete.

Benefits of Warmerwall

HOW AIR TIGHT ARE MY WALLS?

Air leakage typically better than 3m3/(h.m2) without need to parge.

IS IT MAGIC HOW THE WALL PERFORMS THERMALLY?

Not quite, but the High thermal mass combining with low U value and low air leakage does give extraordinary thermal performance that outperforms predicted SAP calcs by about 50% In real world monitoring.

CAN I FIX TO THE WALL WITHOUT NEEDING TO DRILL THE CONCRETE CORE?

Hidden steel fixing strips every 150mm.

IS THERE GOOD RESISTANCE TO THERMAL BRIDGING AT JUNCTIONS?

Junction details provide enhanced resistance to cold bridging.
