Energy Efficiency

A Low Carbon Approach to Cost and Comfort 

Frame TechnologiesTM is at the forefront of developments in insulation and airtightness for timber frame homes - delivering value, energy efficient and environmentally sound, solutions.

Frame TechnologiesTM offers an excellent selection of cutting edge insulation materials.  Coupled with one of our ‘intelligent’ vapour control layers we can deliver outstanding U-Values and airtightness.  The minimum U-Value required in the external walls of a new build house is currently 0.30 W/m²K.  The lower the U-Value, the better the insulation provided by the material.

Frame TechnologiesTM insulation solutions can achieve 0.30 to less than 0.09 W/m²K and can comply with any Standard Assessment Procedure (SAP) calculation requirements. SAP is the protocol adopted by the UK Government to assess the energy performance of new residential dwellings

Here are some more compelling reasons to select timber technology:


Thermal Performance

Insulation is crucial to any domestic energy efficient home.  Modern building regulations dictate high levels and improved standards of insulation.  This is critical to reducing heating bills, less fuel consumption and improved climate care.  Timber is a naturally insulating material and, combined with additional insulation can deliver U-Values as low as 0.09 W/m²K.

Factory-fitted insulation now comes as standard in our drive to help our customers achieve the best possible rating for their building and optimise overall build efficiency. If your project demands it, we can supply your timber technology components and insulation separately for onsite build.

Frame TechnologiesTM carefully consider the sustainability of all of the materials we use. The traditional (non-natural) insulation materials we supply have been selected to be as eco-friendly as possible by sourcing locally and choosing manufacturers with a high awareness of their responsibilities to the environment.

We have many insulation options available but speak to us and we will help you find your optimum solution

Mineral Wool (Glass or Stone) – this delivers zero rated Ozone Depletion Potential (ODP) and the structure of the finished product allows the rolls to be highly compressed when packed, reducing the amount of transport required. Both glass wool and rock wool have a Global Warming Potential (GWP) of less than 5 and an A1 Fire Rating. Options include onsite fitting by Frame Technologies or supply only.

Sheep’s Wool, Hemp and Wood Fibre – these natural products are sustainable, renewable and safe to handle without specialist equipment.  We supply standard sized rolls making installation quick and easy. All products are breathable, will naturally regulate moisture and temperature and have zero Global Warming Potential (GWP). Supply only option available.

Recycled Paper – made from recycled newspapers, we install recycled paper insulation by spraying or blowing it onto walls or into cavities. This method reduces the potential for gaps and will provide excellent airtightness.  This option has a zero Ozone Depletion Potential (ODP) and a negative Global Warming Potential (GWP).  This system is best blown in on site by Frame Technologies specialist team.

Rigid Urethane with Foil Facings – manufactured locally, less than 10 miles from the Frame TechnologiesTM site, the manufacturing process produces no CFCs or HCFCs and delivers zero rated Ozone Depletion Potential (ODP). Options include factory fitted or supply only.



Airtightness measures of the amount of air leaking from your home. A building with poor airtightness will lose a significant amount of heat as warm air escapes. Warm, damp air leaking into the fabric of the house can also lead to condensation. Current Building Regulations have a minimum airtightness of 10m3/h/m2.  To achieve a Code for Sustainable Homes Level 3, an airtightness level of 3m3/h/m2 is required.

Frame TechnologiesTM is able to exceed both of these specifications with airtightness as low as 1m3/h/m2, should your project require it.

Please note once you achieve an Airtightness of 3 or below you are required to install a ventilation system, we recommend you speak to our partners Total Home Environment for further assistance.

With the need to control air leakage as defined in Approved Document L of the Building Regulations, we can supply effective barriers to assist in the reduction of air leakage, which includes:

  • Membranes and/or tapes for sealing joints or apertures around building services.
  • Airtightness detailing in critical areas such as intermediate floor to external wall panels.
  • Battens to form service zones to reduce the need for penetration through the barriers.
  • By using OSB sheathing on internal face of external walls then taped gives excellent results.


SAP / Code Compliance

Frame TechnologiesTM can assist in a wide range of building code requirements and excellent U-Value calculations including air pressure testing, to achieve the highest possible rating for your project. Where planning legislation dictates, Frame TechnologiesTM can assist by offering:

  • Simplified Building Energy Model (SBEM) and SAP calculations – work should not be commenced on site until the ‘as designed’ calculations have been submitted to Building Control.  Upon completion, an ‘as built’ assessment is required and should also be submitted to Building Control together with the Energy Performance Certificate (EPC). 
  • Frame TechnologiesTM can also help with the creation of Energy Statements to offer guidance on building fabric performance and the sourcing of sustainable materials to achieve high BREEAM and Code for Sustainable Homes (CfSH) ratings. We can also advise on improving the building fabric to reduce the Dwelling Emission Rate (DER)
