Thermal Insulation & Insulation
Insulate efficiently, save energy & increase value
High-quality thermal insulation is the key to greater energy efficiency, lower heating costs and a comfortable indoor climate all year round. Whether for new builds, renovations of older buildings or targeted modernisation: carefully selected insulation materials provide lasting protection for your building against heat loss in winter, summer heat, as well as disruptive noise and moisture.
Why is proper thermal insulation so important?
- Significantly reduce heating costs: Up to 30% of heating energy is lost through uninsulated roofs, external walls or basement ceilings. Effective insulation sustainably lowers your operating costs from day one.
- Improve living comfort & well-being: Insulation materials keep heat in the room and prevent cold wall surfaces. This reduces drafts and ensures an even, comfortable indoor climate in every season.
- Protect the building fabric for the long term: The right insulation protects against condensation and mould, permanently preserving and increasing the value of your property.
- Protect the environment & meet requirements: Lower energy consumption means lower CO₂ emissions – an active contribution to climate protection and compliance with current GEG requirements (German Buildings Energy Act). Our range of thermal insulation & insulation products In this category, you will find tailored thermal and insulating solutions for every application in your building:
- Facade insulation & external walls: Maximum thermal insulation from the outside – ideal for reducing heat transmission losses.
- Roof insulation & attic floor boarding: Whether between-rafter, above-rafter or top-floor ceiling insulation – stop rising heat directly at the roof.
- Impact sound insulation & internal insulation: Perfect for renovating intermediate floors and interior walls when external insulation is not possible.
- Basement ceiling & floor insulation: Reliably protects against cold rising from the ground and keeps the ground floor warm underfoot. The right insulation materials for your construction project Different materials are used depending on the requirements and application: Insulation material type Key features & properties Main application area Mineral wool (rock wool & glass wool) Non-combustible, excellent sound insulation, high breathability Roof, facade, drywall EPS / XPS (rigid foam) High compressive strength, extremely moisture-resistant, top insulation value Perimeter insulation, screed, flat roof Ecological insulation materials Renewable, sustainable, excellent summer heat protection Interior finishing, timber construction, roof
What should you look for when buying insulation materials?
When choosing the right insulation material, pay particular attention to its thermal conductivity (WLS/WLG): the lower this value, the better the material insulates even at a low thickness. The building material class (fire protection) and moisture protection also play a decisive role in the durability and safety of your insulation.

Insulation
The Perfect Insulation for Your Home
Why Insulation Is the Best Choice for Your Home
With our insulation, you can choose tested brand quality that delivers tangible, lasting benefits:
Save the most money: Stop unnecessary heat loss through your roof, walls and basement. Reduce your heating costs by up to 30% from day one and effectively protect yourself against rising energy prices.
The perfect comfortable climate all year round: Say goodbye to cold walls and draughts in winter, as well as oppressive heat in summer. Our insulation materials ensure a consistent, pleasant indoor temperature all year round.
Safety & building protection for decades: Prevent moisture and dangerous mould growth. Our moisture- and fire-protected materials preserve your property’s structure and safeguard its value over the long term.
Easy selection for every project: Whether it’s a new build, renovation of an older building or a DIY project, our clearly organised product categories and coordinated materials make it easy to find exactly the right solution without a lengthy search.
It depends on the application. Mineral wool (stone or glass wool) is ideal for roofs and drywall partitions thanks to its high level of fire and sound protection. For building elements in contact with the ground, such as external basement walls or areas beneath the screed, moisture-resistant and pressure-resistant rigid foam boards such as EPS or XPS are the best choice.
The thermal conductivity level (WLS) indicates how well a building material conducts heat—and therefore how well it insulates. The lower the value (e.g. WLS 032 compared with WLS 040), the better the material’s insulation performance at the same thickness.
Proper insulation of the roof, façade and basement ceiling can save up to 30% or more of heating energy. The exact savings depend on the condition of the building before renovation and the insulation thickness selected.
Yes, internal insulation is the ideal solution when external insulation (e.g. due to heritage protection requirements or property boundaries) is not possible. It is important to use vapour-permeable materials or a correctly installed vapour control layer to prevent condensation from forming.
