Attic insulation in a modern way – with expanded foam

If the attic is yet to be built on, or the interior covering (e.g. drywall, paneling) has not yet been installed, now is the time to effectively attic insulation! The modern closed-cell purfoam insulation attic When applied from the inside, we obtain thermal, water and air tightness at the same time.

Gap-free and joint-free attic insulation

Traditional cotton insulation can easily slip, collapse, and become moldy over the years due to moisture or humidity. In contrast, closed-cell foam adheres seamlessly and continuously to the roof surface. It does not slip, does not move, completely airtight forms a layer. The foam goes exactly where it needs to go – and stays there.

Best thermal insulation 

Based on the lambda value, it can be said that PU foam is the best thermal insulation material available today. PU foam can achieve the same thermal insulation capacity with up to half the thickness of traditional insulation materials. This is especially important in attic spaces, where the height of the rafters is limited - usually 15 cm. In this thin space, it is almost impossible to install strong insulation that meets today's standards using traditional materials. 

❌ Weaker thermal insulation
Cotton cannot compete with modern insulation materials.

❌ No waterproofing ability
It does not provide protection against moisture or moisture.

❌ Not seamless
It can slip or collapse due to external influences. Gaps can form through which heat escapes.

❌ Limited options due to rafters
The proper thickness barely fits between 15 cm rafters.

❌ Difficult to install
Board materials are heavy and require a lot of cutting and fitting.

❌ A favorite hiding place for insects and rodents
It does not pose a barrier to uninvited residents.

❌ It gets hot in the summer.
It does not protect against attic heat.

❌ Fragile, soft material
It is easily broken, not a permanent solution.

✅ Outstanding thermal insulation
The most efficient solution for attics available today. Lambda value: 0.022

✅ Timeless, waterproof
It is not damaged by moisture or moisture – it does not require a vapor barrier.

✅ Seamless, airtight
No gaps, no air pockets. Stable, doesn't move. The foam stays where it's put - forever.

✅ Thinner layer, same performance
Half that thickness is enough for the desired thermal insulation.

✅ Does not attract rodents
Mice and rats don't move into the purhab.

✅ Protects against summer heat too
It does not let in the heat of the sun's rays - a cool attic even in summer.

✅ Strengthens the roof structure
The solid, rigid layer also makes the roof more statically stable.
