PU Foam

Filling the Gaps Standard Sealant Can't

Window frames, door installations, and pipe penetrations rarely leave a clean, uniform gap behind, which is exactly the kind of irregular space a standard sealant struggles to fill properly.

PU foam sealant in the UAE projects gets specified for this reason specifically: it expands into uneven gaps and cures into a firm, insulating fill that a flat bead of sealant simply can't replicate.

LAYRA supplies PU foam for construction gap-filling, insulation backing, and general sealing work where the fit isn't predictable in advance. Window and door installation crews tend to keep it on hand as a standard item, since every opening varies slightly in size and shape, and a flexible, expanding product handles that unpredictability far better than something rigid.
