Benefits of Sustainable Construction

  • Natural Renewable Construction Materials
  • Precision Engineering Off Site
  • Rapid Construction on Site
  • Reduced Costs
  • Minimised Disruption
  • Reduced Traffic / Noise during construction
  • Minimal Site Waste
  • Excellent Energy Efficiency
  • Low Maintenance Building
  • Provide low waste to landfill even on deconstruction.

Sustainable Buildings

Sustainable building is high on the agenda, and discerning clients also want to know that their new green building is future proofed against ever tightening energy efficiency/Building Control  measures.

Cabinco Structures ensure that not only is your timber eco building sourced from sustainable materials, but it will also be energy efficient to a point considerably beyond current Building Control requirements.  This is done by increasing the levels of insulation and improving the levels of air tightness in all our buildings to ensure the energy you pay for is retained as heat within the building.


The main component of all our sustainable buildings is timber: the only construction material which is fully renewable, and recyclable.  All timber components are responsibly sourced from well managed forests as standard.   Timber provides a permanent carbon lock when used in construction.  These properties provide an excellent basis for today’s modern eco buildings.


Our standard specification uses either Western Red Cedar or Siberian Larch (laxis sibirica) for the external cladding, both species are naturally weather resistant, and do not require ongoing preservative treatment.  They can be allowed to gradually “weather” to an attractive silver-grey hue without any detriment to performance. This reduces maintenance costs and negates use of preservatives on site.

Cabinco Structures cladding style ensure that the edges are designed to meet flush and therefore provide a contemporary, “streamlined”, finish in keeping with modern premises.


Our buildings are extremely well insulated as standard, using high quality, proprietary products such as Kingspan.


In response to client demand, Cabinco Structures now offer a Structural Insulated Panel construction system which retains the popular external appearance of our MPL buildings, but provides the option for plasterboard finish on the interior of the building.  This further reduces costs and time on site and also improves air tightness of the building.


U values describe the thermal performance of a material. The lower the U Value, the better the material performs.

Standard U Values based on our minimum specification with 150mm solid board insulation:

Floor 0.14 W/m²K (floor covering could improve this figure)

Walls 0.14 W/m²K

Roof 0.14 W/m²K (depending on roof type)

These can be reduced still further through increased insulation or wall log thickness.


Timber windows and doors are all factory pre-finished to a very high standard to reduce maintenance costs. They are all double glazed as standard with toughened or laminated glass used throughout. Options exist for B’ rated energy windows which are “Secure by Design”.

FSC window and doors can be supplied where required.

1.49 W/m²K overall transmittance (U value) for standard window units

Argon filled 4/18/4 low E glazing units with U value of 1.1 W/m²K

Triple glazed window units can be brought down as low as 0.6 W/m²K


Our standard roofing material is Metrotile which is 60% recyclable and comes with a 40 year manufacturer’s guarantee.

Popular options include; Single Ply Membrane which has a 25 year guarantee or  cedar shingles or sedum amongst others.  Provided we are aware at the design stage – most roofing options can be accommodated.


A wider selection of sustainable options are available including:

  • Ground Source Heat Pumps
  • Biomass heating
  • Rainwater Harvesting
  • Roof lights
  • Sun-tunnels

Other issues which may be of interest to clients looking for sustainable buildings include the on-site management of waste.  For details of our work here please see the blog post below:
