The structural implementation of terrace solutions is often a technical challenge because the space for the layer sequences is very limited.

The required thermal protection, the variety of flooring materials - a gradient design for the seal must be coordinated.

Bitbau DÖRR has for each object the right solution.

Terrace Inverted Roof

In this type of roof construction is the roof sealing below the insulation and is well protected from all external influences. This circumstance has a positive effect on the aging behavior and thus on the life expectancy of the seal.

 

The insulation has to withstand rain, snow and other wet weather. Therefore, XPS insulation are suitable due to their closed cell structure. In addition to the resistance to moisture ROOFMATE XENERGY insulations are pressure-resistant.

Terrace Warm Roof with Vacuum Insulation

Today's thermal insulation requirements are on such a high level that barrier-free transitions between floor constructions and adjacent insulated terrace constructions with conventional insulation materials are not feasible.


The vacuum insulation we offer is a high-performance thermal insulation material, which provides up to 5 times better insulation values than conventional insulation materials and thus the formation of barrier-free terrace outputs can be realized.

Terrace Inverted Roof 2ply

In Austria the 2ply installation of XPS insulation for inverted roofs is recognized in the Austrian regulations (ÖNORMEN) only for energy renovations. That means in new building constructions this form of application solution is based on the general building permit approval in Austria. The basics of the BTZ have to be considered.

 

If the conditions allow it the benefits of an inverted roof construction outweigh. Moreover, at the present-day requirements of thermal insulation (passive house) are also met.

Terrace Duo Roof

Is a combination of a warm and inverted roof where both advantages are combined. The breakdown of the insulation layers should be carefully considered because if the XPS insulation (XENERGY) is much thicker, the roofing in relation to external influences is better protected.

 

In this type of roof solution, the gradient can be carried out at the warm roof level and the inverted roof above provides protection against thermal and mechanical effects on the sealing.

Terrace Warm Roof

The waterproofing membrane protects the thermal insulation while an underlying vapor barrier sheet governs the building physical balance. In order that the waterproofing membrane sustains these influences as long as possible and thus reaches an above average service life, bitumen sheets in "premium" quality are advantageous.

 

PUR / PIR insulation systems have a particularly good insulation value, therefore thinner insulation thicknesses is often enough to meet the heat protection standards. A sophisticated gradient insulation system enables the production of the slope in the insulation layer and not in the supporting structure. This saves valuable space and time.
