A roof renovation does not necessarily have to be associated with noise, dust and restrictions for the residents. With a Refurbishment from the outside the interior remains fully usable - without interrupting your home. Existing insulation, if intact, can be reused and efficiently added to. The result: noticeably improved living comfort and increased energy efficiency - without having to leave the house.
Why renovate from the outside?
Traditional refurbishment is often carried out from the inside, which means that the attic cannot be occupied during the construction period. For owners and tenants, this means restrictions in everyday life - especially in occupied single-family homes or apartment blocks. Refurbishment from the outside offers a convenient alternative here: all work is carried out through the roof without interfering with the interior.
Interior remains fully usable
A major advantage: walls, ceilings and furnishings remain untouched. Residents can continue their everyday lives as usual while the roof renovation takes place outside. This method is particularly advantageous for inhabited buildings, as No removal or elaborate protective measures in the interior are necessary.
Continue to use existing insulation
A common misconception is that the entire insulation needs to be removed every time a roof is renovated. In many cases, however, the existing insulation layer is still functional. If the existing insulation is intact, it can be left in the roof structure. and supplemented with additional materials. This saves resources, reduces costs and shortens the construction time.
Efficient solution through overinsulation
The so-called Overinsulation is a particularly clever method: an additional layer of insulation is laid over the existing insulation layer - for example with SAGLAN glass wool and one Soft fibreboard - installed. This construction enables the required U-value to be achieved, improves heat insulation in summer and increases the energy efficiency of the entire building.
Creating airtightness with sky light covering membrane
A common problem with older roofs is a lack of airtightness. Leaks or missing sealing levels lead to heat loss and moisture problems. With the Sager cover sheet sky light airtightness can be reliably created over the existing insulation. It acts as an airtight layer and provides permanent protection against heat loss.
Conclusion
Temperatures rise quickly in summer, especially in attics. The additional insulation improves the Summer heat insulation noticeable: the attic remains cooler and the indoor climate more pleasant. At the same time, the insulating effect in winter ensures that the heat remains in the building. The result is a consistently high level of living comfort all year round - with reduced energy consumption.
