Warm Deck Roof Boards

Insulating a timber deck flat roof can be done using warm deck construction method or cold roof construction method.

Warm deck roof boards.

To insulate a flat roof with a concrete deck we recommend a warm deck construction method where the vapour control layer is sandwiched between the concrete deck and a layer of rigid pir insulation boards. It is recommended where possible to use the warm deck method of insulation where the principal layer of roof insulation is positioned above the structural deck. Celotex td4000 is purpose designed for use in light traffic flat roof applications. The concrete deck can offer greater speed of roof construction which is an important consideration on many larger commercial projects.

We would like to show you a description here but the site won t allow us. Celotex td4000 comprises a polyisocyanurate rigid foam insulation core with a thermal conductivity of 0 022 w mk and low emissivity aluminium foil facings on both sides bonded to a layer of 5 5mm wbp exterior grade plywood. The insulation can be adhered mechanically fixed or loose laid. The insulation is immediately below the waterproofing layer.

A warm flat roof or a built up roof bur is one where all the insulation is above the joists deck making them part of the warm fabric of the building.
