Durabase There are many benefits to choosing a Durabase over a tradiontional base...

Quicker.... The Durabase arrives in kit form, complete with flooring and under-floor insulation ready for quick and easy assembley. The average base can be installed within the a day!

Easier.... Uneven or sloping sites and difficult site access are easily overcome with Durabase.

Cleaner.... There's no need for large scale excavations, which minimises the amount of soil to dispose of and distruption caused to the site

Cost Effective.... No need for expensive relocating of manholes or drains

Straight forward installation.... Durbase is suitable for either professsional or DIY installation. Durabase can be assemled with just a little DIY experience. No specialist tradesmen or bricklayer are required. The modular walls are bricked and motared before they are delivered to site, with just bridging tiles to be fitted on site.

U-Values…. The following U-values can now be achieved with the Durabase system. Walls 0.27W/m²k and Floors 0.22W/m²k.

There are 4 options for the Durabase system

Full Height Glazing

Full Height Glazing - Durabase for conservatories

This option is used for conservatories with no dwarf wall. Cill fixes directly to outside beam of the base and is finished off with an insulated floor

Modular Dwarf Wall

Modular Dwarf Wall - Durabase for conservatories

An ideal alternative to traditional brickwork. Along with the base system of the Full Height option, the galvanised steel modular dwarf wall system comes pre-clad and pointed with only bridging tiles to be fit on site.

Durabase + Modular Wall/Full Height Conservatory Base System

Durabase + Modular Wall / Full height conservatory base system

This system has all the advantages of the standard system but with the capability of achieving an even greater U-value. The specially designed steel base and flooring insulation can achieve an impressive U-value of 0.22 W/m2K. Matched with the modular walls, when insulated and finished off with foil-backed plaster board (U-value of 0.27 W/m2K), the Durabase+ delivers a more energy efficient base. This base is ideal for use in Scotland as it can assist in getting a successful building warrant application.

Selfbuild Traditional Brickwork
