REW11 – Retro Ecowall – Party Wall Flush Detail – Plan
Price range: £9.00 through £14.00 + VAT
This plan detail shows a flush junction treatment where the Retro Ecowall system meets a party or separating wall, applied to a 215mm solid brick wall.
A minimum 1000mm return of the system is required on both sides of the junction. The system is returned along the party wall with a reduced thickness of 20mm Gutex Thermoroom boards, finishing flush with the main wall insulation face. An alternative detail shows a 40mm return board thickness with 15mm existing lime plaster retained in lieu of insulating plaster. An option to extend the system for the full length of the wall to avoid a step is also indicated. This detail should be read alongside REW09 and REW10, which show the stepped and tapered party wall junction options.
See drawing notes for full information.

Featured Products
Gutex, based in Germany, is a fourth generation family run company and leading manufacturer of woodfibre insulation boards. Gutex was the first in Europe to manufacture insulation boards from ecological wood fibre, incredibly this was in 1932. Testament to Gutex's continuous innovation philosophy, they became the first manufacture to produce single-ply homogeneous wood fibreboard insulation using a low-energy dry process which allowed the production of thicker higher quality boards, providing superior thermal storage capacity.
Diathonite Thermactive is a breathable lime and cork-based insulating plaster designed for internal solid masonry walls and ceilings. It improves thermal performance while allowing moisture to move naturally through the wall, helping to reduce condensation and maintain a healthier indoor environment, making it particularly well suited to older, solid-wall and retrofit properties.
Lime Green Solo is a breathable, one-coat lime finishing plaster for internal walls and ceilings, designed to provide a smooth, durable finish over masonry, lime plasters and wood fibre insulation boards. Made from natural lime-based materials and free from cement, it helps regulate moisture, reduces the risk of condensation and mould, and is particularly well suited to the renovation and retrofit of older, solid-wall buildings where breathability is essential.
