PU Expanding Foam for Gap Filler and Insulation

Benefit of Using DLG PU Foam for Sealing and Insulation

The DLG A6618 PU Expanding Foam is an essential tool for modern construction in Kenya. It is designed to replace slow and inefficient mortar for fixing window and door frames. The foam expands up to 45 times its original volume, creating a complete airtight and weatherproof seal that improves a building’s energy efficiency and protects against dust and pest infiltration.

Key Features of DLG PU Foam

1. High Expansion Yield & Stability

Our formula provides a high-volume yield from a single 750ml canister, making it cost-effective for large projects. The cured foam has a stable, closed-cell structure that does not shrink or collapse over time, ensuring the seal remains intact for years.

2. B2 Fire Retardant Rating

Safety is critical in commercial and residential buildings. The A6618 foam is rated B2 according to DIN 4102, meaning it is self-extinguishing and will not sustain a flame. This makes it the required choice for sealing fire-rated doors and electrical penetrations. For general-purpose filling, we also offer a standard B3 grade (A6615).

3. Excellent Adhesion & Structural Support

This foam is not just a filler; it is also a strong adhesive. It bonds aggressively to most construction materials (except Teflon, PE, and PP), helping to stabilize window frames and reduce the need for excessive mechanical fasteners.

4. Superior Thermal and Acoustic Insulation

The dense structure of the cured foam effectively blocks heat transfer and dampens sound. Use it to insulate pipes, reduce plumbing noise inside walls, and create quieter living or working spaces.

Primary Applications of the Foam in Kenya

• Mounting Window and Door Frames: Provides a fast, secure, and insulated fixing method for timber, uPVC, and aluminium frames.

• Filling Cavities: Seals large, irregular gaps around pipes, vents, and utility lines passing through walls.

• Sealing Roof Structures: Fills gaps between roofing sheets and wall plates to prevent drafts and water ingress.

• Soundproofing: Used to fill voids in partition walls and around door jambs to reduce noise transmission.

How to Use for Best Results

• Surface Prep: Surfaces must be clean and free of grease. Lightly spray the cavity with water, as the foam requires moisture to cure properly.

• Application: Shake the can vigorously for at least 60 seconds. Invert the can and apply steady pressure. Fill the gap to about 50% capacity to allow for expansion.

• Curing & Finishing: The foam will be tack-free (non-sticky) in 10-15 minutes. It can be cut or trimmed after 60 minutes. For best results, allow 24 hours for a full cure before painting.
