Garden office construction details
Garden room structure
Our Garden Buildings are built to last. They are fully insulated for year round occupation. A garden room normally takes between 7-12 days to build, depending on the style and base.
An ODAS Garden Room or Garden Office is built from treated 4 by 2 (96mm x 47mm )C24 & C16 structural grade timbers. We cut and build the wall frames on site. Our roofs are constructed from 6 by 2 C24 timber.
The floors of our garden buildings are boarded underneath with 9mm Plywood or OSB wrapped in a breather membrane to protect them from moisture and against vermin. This layer of boarding holds the insulating PIR foil-foam panels under the base.
The breather membrane prevents any moisture that may have entered the external cladding from penetrating further into the garden building. Being breathable it allows any moisture vapour trapped in the walls to escape .
Vapour Control Layer (VCL)
Our ODAS Garden Room and Offices come with a vapour control layer to prevent condensation occurring between the insulation and the plasterboard. The VCL prevents warm moist air passing form inside the garden room into the walls of the structure where it can condense on the cold inside face of the outer wall, causing damage.
Garden room insulation
All ODAS Garden Rooms and Garden Offices are insulated with PIR foil-foam insulation (like Celetex or Kingspan). We insulate the walls, floors and ceilings.
