Thermal & Acoustic Benefits

Timber frame has all the answers on Acoustic and Thermal Solutions.

Environment & Sustainability


Thermal Insulation

The thermal insulation of a building is measured by its "U-value". A U-value measures how well a building component, e.g. a wall, roof or a window, keeps heat inside a building. The lower the u value, the better the insulation provided by the material.

The minimum U-value required in the external walls of a new build house is currently 0.30. With the Code for Sustainable Homes now coming into force lower U values are now being asked for. We have been working in partnership with insulation manufacturer Isover to provide system solutions that can achieve 0.30 to under 0.10 U values giving our customers a full range of options to choose from for any type of project and to comply with any SAP calc requirements.

Acoustic Performance

The modern world is an increasingly noisy place. Car and home alarms, busy roads, barking dogs...

Timber frame is the ideal solution for developers who need to limit the presence of external noise within their projects.

In an acoustics study the Building Research Establishment found that

"If all dwellings had sound insulation as good as that measured in the party walls of timber frame dwellings, the problem of noise from neighbours would be greatly reduced."

BRE's "Case study TF2000" found that even a multi-storey project would out perform building regulations for acoustic insulation.

An additional benefit of timber frame is the reduction in the length of time neighbouring buildings are disturbed with construction noise, due to the faster speed of construction.

Sustainable Materials

As you'd expect from Frame Wise Ltd, we have chosen a sustainable insulation solution.

ISOVER is made from glass mineral wool: its raw material is silica sand, the earth's most abundantly occurring natural material. The material has very little environmental impact across its lifetime, being easily manufactured, installed and disposed of.

80% of the glass used within the products is recycled glass sourced from post consumer waste or glass manufacturing facilities. At the end of its lifetime the insulation can then itself be recycled.

The manufacture of the insulation doesn't produce any dangerous gases such as CFC's and HCFC's.

Products are delivered to us in high compression packaging, meaning that more material can be delivered on a load - this reduces the environmental impact of transportation.

Due to these factors, ISOVER achieves a full credit under the BRE EcoHomes performance for zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than 5.

SAP (Standard Assessment Procedure) Calculations are an assessment protocol for the energy performance of new residential premises, which from the 7th April 2006 have been required for all dwellings.

Code for Sustainable Homes (CfSH)

The Code for Sustainable Homes has replaced EcoHomes in England from April 2007 and introduces minimum standards for energy and water efficiency at every level of the new national standard. The Code measures the sustainability of a home against key design categories, rating the 'whole home' as a complete package. The minimum standards for Code compliance have been set above the requirements of Building Regulations. New homes can achieve a rating on a scale of one to six 'Code Levels' depending on the standard achieved.

The key design categories included within the Code are:

  • Energy
  • Water
  • Materials
  • Surface water run-off
  • Waste
  • Pollution
  • Health & Well-being
  • Management
  • Ecology
