Introduction
In the dynamic construction and maintenance sector of Pakistan, efficiency and durability are key. Whether you’re sealing gaps around windows, insulating pipes, or filling cavities in walls, you need a product that expands, adheres, and insulates reliably. Soudafoam by Soudal is a one-component, moisture-curing, self-expanding polyurethane foam designed to meet these exact needs. With its high yield, excellent adhesion, and superior insulation properties, Soudafoam has become the go-to solution for contractors, builders, and DIY enthusiasts across Karachi, Lahore, Islamabad, and beyond. This guide dives deep into why Soudafoam is an essential product for any sealing or insulation project in Pakistan.
What is Soudafoam?
Soudafoam is a ready-to-use polyurethane foam that comes in a convenient 750ml aerosol can with a gun applicator. It cures upon contact with atmospheric moisture, expanding to fill gaps and cavities completely. Its unique Duravalve technology ensures optimal yield and consistent performance throughout its shelf life, even if stored horizontally. This makes it a reliable and efficient choice for a wide range of applications.

Top Benefits of Using Soudafoam in Pakistan
- High Yield & Cost-Effective:One 750ml can yields approximately 22 meters of foam bead or 28 liters of expanded foam, providing extensive coverage and excellent value for money.
- Excellent Insulation Properties:With a low thermal conductivity (0.037 W/m.K) and 58 dB sound insulation, it significantly improves energy efficiency (reducing AC/heating costs) and acoustic comfort in homes and offices.
- Strong Adhesion & Stability:Adheres strongly to most construction materials (concrete, wood, metal, masonry) and shows no shrinkage or post-expansion, ensuring a permanent, reliable seal.
- Versatile Applications:From sealing window frames to filling pipe penetrations and roof cavities, it serves multiple purposes in construction, renovation, and MEP (Mechanical, Electrical, Plumbing) works.
- Easy to Use with Gun Applicator:The can is designed for use with a foam gun (available separately), allowing for precise, controlled, and less wasteful application compared to straw-applied foams.
- Freon-Free & Ozone-Friendly:Environmentally conscious formulation that does not harm the ozone layer.
Primary Applications in Pakistan
- Sealing Gaps & Openings:Around window and door frames, air conditioning ducts, and electrical conduits to prevent dust, insect, and water ingress.
- Cavity Wall & Roof Insulation:Filling hollow spaces to enhance thermal and acoustic insulation, crucial for Pakistan’s extreme summers and winters.
- Pipe & Cable Penetration Sealing:Sealing around pipes and cables passing through walls/floors to maintain fire ratings and prevent leakage.
- Fixing & Anchoring:Lightweight anchoring and fixing of elements where mechanical fixing isn’t feasible.
- Soundproofing:Creating acoustic barriers in partition walls, home theaters, or commercial spaces.
Step-by-Step Application Guide
- Preparation:Shake the can vigorously for at least 20 seconds. Ensure surfaces are clean, dry, and free from grease and dust.
- Moistening:For optimal curing, lightly moisten the surface with a water sprayer before application. This is crucial in Pakistan’s dry climate.
- Application:Attach can to a Soudal foam gun. Fill cavities or gaps only 2/3 full, as the foam will expand significantly (2–3 times). Shake the can periodically during use.
- Layering:For deep fills, apply in layers, moistening between each layer.
- Curing & Finishing:Allow foam to cure fully. It can be cut, sanded, plastered, or painted after 25 minutes. Protect cured foam from UV rays by painting or sealing with a compatible sealant (silicone, PU, etc.).
Frequently Asked Questions (FAQs)
Q1: Is Soudafoam waterproof?
Once fully cured, Soudafoam is water-resistant and makes an excellent barrier against water and air infiltration. However, for constant water immersion, a specialized waterproof sealant should be used over the foam.
Q2: Can it be used for outdoor applications in Pakistan’s weather?
Yes, but with a crucial step: Cured foam is NOT UV-resistant. For any outdoor application (like roof gaps or exterior window seals), the cured foam must be protected by overpainting or covering with a weatherproof sealant (like silicone or polyurethane sealant) to prevent degradation from sunlight.
Q3: What surfaces does it not stick to?
It does not adhere to Polyethylene (PE), Polypropylene (PP), and Polytetrafluoroethylene (PTFE/Teflon®). Always perform an adhesion test on unusual or plastic surfaces.
Q4: How long does it last once applied?
When applied correctly and protected from UV exposure, Soudafoam provides a permanent, stable seal that does not shrink or lose its insulating properties over time.
Q5: Is it safe to use indoors?
Yes, but always use in a well-ventilated area and wear appropriate PPE (gloves, goggles). The foam emits vapors during application that should not be inhaled.
