Volumetric Off Site Manufacturing using timber

------------------------------------------------------------------------------

Quality

Relocating traditional site works into a controlled manufacturing environment allows us to maintain exceptionally high levels of quality during manufacture. Our homes and materials aren't affected by environmental conditions therefore eliminating rework and having an overall positive impact on the elimination of defects.

Thermal performance

Timber is a highly efficient insulating material even before insulation is installed. Timber framed homes can far exceed current building regulations in the UK allowing a reduction in life cycle costs.

Noise transmission

Timber walls and floors inherently have exceptional resistance to noise transmission. Manufacturing our homes volumetrically allows Hunter staff the opportunity to work in areas considered inaccessible with traditional building methods. We can ensure service penetrations and other noise transmission routes are effectively sealed.

Progressive collapse and affect by fire

Timber has good resilience when exposed to great heat. Although timber will char and burn when exposed to fire, it retails its structural integrity longer than steel and brick which tends to buckle and crumble earlier. This characteristic coupled with attention to design detailing reduces the risk from progressive collapse.

Eco friendly

V-OSM dramatically minimises construction waste and increasing recycling awareness, whilst conventional buildings and their materials such as concrete and blocks have an extremely high impact on the environment. Conventional processes to deliver and fix traditional materials produce extremely high levels of carbon emissions which is not the case for V-OSM.

Sustainability and use of renewable materials

Timber is a sustainable and renewable product with more trees planted each year than those felled. Hunter only buys timber from approved suppliers.

V-OSM -v- Traditional build

We supply homes quicker than traditional builders, of higher quality and on fixed lump sum contracts. V-OSM dramatically eliminates and is a better environment for the promotion of innovation, value engineering and partnering.

Compliance

------------------------------------------------------------------------------

 

Building Control

LANTAC is linked to all national local authorities and is recognised as a fast track route for building control. We have obtained 'systems' approval.

 

Warranty

Hunter's manufacturing process is recognised by Zurich. Our homes are timber based and we work with current specifications and industry standards to allow warranty by all the major warranty bodies. Such bodies understand that the use of timber in V-OSM conditions reduces the risk of post-completion warranty claims.

 

Scheme Development Standards

The Hunter system offers clients design flexibility and coupled with our understanding of delivering to RSLs, we can ensure compliance with the current SDS.

 

Timber Details

Our typical timber frame details are recognised by TRADA. We are a registered member of TRADA.

 

Party Details

We understand the criticality of party conditions and work to better the standard robust details.

 

Code Of Sustainable Homes

We can calculate ratings for our units once adapted to meet the client design requirements and assist in achieving at least Code 3 and above.

 

Energy Rating

Our system offers exceptional SAP ratings.
