Lambdabloc® - the only strong thermal bridge solution
The Lambdabloc is the solution for the most common thermal bridges
- Wall base on full ground
- Wall base on (crawl) cellar
- Ground floor walls on (crawl) cellar
- Flat-roof roofing edge
- Flat-roof connection with rising cavity wall under masonry wall
- Sloping roof connection with rising cavity wall under masonry wall
- Under rising attic walls (AUV), under interior walls and inner cavity leaf
A poorly constructed thermal bridge leads to large heat losses, in all directions!
That's why Ploegsteert developed their Lambdabloc.
A thermally improved connection block with a highly insulating mineral wool in the vertical perforations. In this way all heat loss is prevented.
Not only the horizontal heat flow but also the diagonal and vertical heat losses are stopped, which is necessary for a proper thermal bridge solution!
The Lambdabloc® from Ploegsteert has an insulating capacity (λ-value) in 2 directions:
- horizontal lambda value: λ = 0.14 W/m.K
- vertical lambda value: λ = 0.18 W/m.K

The Lambdabloc® is a thermally improved brick, with a porous structure in fired clay, of which the vertical perforations are filled with mineral wool. The insulated building block with tongue and groove is ideal for non-decorative masonry.
