Insulating a flat roof...

Improved thermal efficiency has positive effects on the environment through reduced energy usage. There are different options with their own benefits depending on whether you are constructing a warm roof or inverted roof, the useage of the building, and what the project requirements are.

The insulation for flat roofs is commonly produced as rigid boards making them easy to handle and install with the variety of waterproofing types and systems. Ordinarily, polyisocyanurate (PIR) insulation is used within warm roof construction as it has excellent dimensional stability and compressive strength, which enables it to withstand foot traffic without depression. Within an inverted roof construction the insulation needs to be able to endure a ‘buried’ scenario beneath ballast or a green roof without detriment to its properties or insulating capability; and so forms of polystyrene are utilised.

Bauder Warm Roof Insulation

BauderPIR is both strong and inert and has a goodcompressive strength making it suitable for all kinds of load bearing decks in warm roof construction.

BauderPIR FA Tapered is a lightweight, convenient, easy to install and cost-effective alternative method of providing falls to a roof instead of incorporating them into the structure.

BauderVIP is a vacuum insulation panel designed to provide high thermal performance in areas with limited installation height and is ideally suited for roof terrace applications. 

BauderROCK is our mineral fibre insulation with exceptional acoustic and fire resistance properties. The insulant is considerably heavier than PIR and may not be suitable for all warm roof constructions.

BauderGLAS is a non combustible cellular glass insulation that gives high compressive performance.
