Tim Nicholson and family are undertaking and documenting the refurbishment of their 4 bed 1960s end of terrace town house in Central North Oxford to create an ultra-low energy comfortable family home. A range of measures to save energy and generate renewable energy are being undertaken, combined with some alterations to update the interior and improve the house’s layout.
Measures include: high levels of insulation in the walls, roof and floor; creation of a new brick wall to create a second cavity for insulation; high levels of airtightness throughout; and use of mechanical ventilation with heat recovery (MVHR). 

The project was the first to use a new form of basalt Teplo Tie to tie existing brick work across a wide cavity to a new masonry leaf. This Teplo variant - known as the Teplo –L- tie - has only just been launched and has a stainless steel fixing fitted to the end. This allows a low conductivity connection between a steel, concrete or timber frame and a masonry outer skin.

The Teplo -L- tie can allow a faster build process and means that no expensive resins are needed on site to fix the tie as simple screw / plug or wood screw fixing can be used to "face fix".
The stainless steel end makes very little difference to the thermal conductivity of the tie. The tie gives an additional U-value contribution (ΔU; assuming 2½ ties/m2) as low as 0.00038 w/m²K.

Tim Nicholson commented: ““We were very pleased to discover the new Teplo -L- tie. Given our high levels of insulation we were keen to use a very low conductivity tie – Teplo was the obvious choice. However, with the existing brick wall already in place it was going to be quite a challenge to drill and chem-fix all the ties into place. The Teplo -L-tie offered a very user friendly and more affordable solution.” The Teplo-L-Tie was supplied to this project by the Green Building Store.
