OYH: Where noticeable workmanship satisfies certain solidity. Our team guarantee every product certainly not just appears remarkable but likewise really experiences considerable as well as dependable in everyday utilization around the world.
OYH has the solution to a boxed product based on a simple idea. We deal with design, materials, production and delivery. A single destination to all your manufacturing requirements.
Spray polyurethane foam insulation offers superior thermal performance, sealing air leaks and creating a continuous barrier against heat loss. This versatile material expands to fill cracks and crevices, providing an R-value up to 6.5 per inch, far exceeding traditional fiberglass. Homeowners benefit from reduced energy bills, as it minimizes the workload on HVAC systems during extreme weather. Additionally, its moisture-resistant properties prevent mold growth and structural damage. When applied professionally, spray polyurethane foam insulation enhances indoor comfort year-round. OYH specializes in high-quality formulations that ensure durability and eco-friendliness, with low VOC emissions for healthier living spaces. Unlike batt insulation, it conforms to irregular surfaces without sagging. Investing in this insulation type not only boosts property value but also supports sustainable living by lowering carbon footprints. For optimal results, consult experts to assess your home's specific needs and achieve maximum efficiency.
Spray polyurethane foam insulation is a game-changer for airtight home sealing. Applied as a liquid, it expands rapidly to form a dense, adhesive foam that adheres to wood, metal, and concrete surfaces. This creates an impenetrable seal against drafts, pests, and allergens entering your living space. With its closed-cell structure, it acts as both insulation and a vapor barrier, reducing condensation issues in humid climates. Energy audits often show up to 50% improvement in air tightness after installation. OYH's spray polyurethane foam products are designed for easy application in attics, walls, and crawl spaces, ensuring comprehensive coverage. This insulation method outperforms rigid foam boards by eliminating thermal bridging. Beyond energy savings, it contributes to quieter interiors by blocking external noise. Proper installation requires trained professionals to achieve uniform thickness and avoid over-expansion. Embrace spray polyurethane foam insulation for a more secure, efficient home environment that stands the test of time.
Installing spray polyurethane foam insulation demands precision to maximize its insulating power. Begin with surface preparation, removing debris and ensuring dryness for optimal adhesion. Professionals use specialized equipment to spray the two-component mixture—polyol resin and isocyanate—which reacts on contact to form the foam. Open-cell foam suits interior applications for its sound-dampening qualities, while closed-cell is ideal for exteriors due to its rigidity and water resistance. Thickness varies by climate zone, typically 3-5 inches for walls. Safety protocols include protective gear to handle chemicals safely. OYH provides reliable spray polyurethane foam insulation kits tailored for DIY enthusiasts and contractors alike. Post-installation, curing takes about 24 hours, after which the space can be finished. This process not only insulates but also reinforces structural integrity. Compared to blown-in cellulose, it offers longer-lasting performance without settling. Choose spray polyurethane foam insulation for a seamless, high-performance upgrade that enhances comfort and efficiency in residential and commercial buildings.
Four primary issues commonly lead to mold, mildew, rising damp, and efflorescence: Mold caused by inadequate ventilation Mold resulting from internal condensation Mold induced by driving rain or roof leaks Rising damp and efflorescence attributed to salt contamination
For non-porous substrates such as metal and glass, silicone-based sealants are recommended. For porous substrates like concrete, bricks, and masonry, polyurethane sealants are the preferred choice. In applications requiring broad adhesion compatibility (e.g., window installations), silane-modified polymer sealants are uniquely suitable due to their versatile bonding properties. For joints that are too wide for conventional sealants or demand enhanced waterproofing, consider joint tapes, swellable profiles, waterbars, or injection hose systems—selection should be tailored to the project’s specific requirements.
Flashing materials are key components in building waterproofing engineering, used to treat special parts such as corners and gaps. Their core function is to prevent water seepage from building joints, especially for waterproof sealing of roofs, walls, pipes, and other components. Flashing materials: Include waterproof membranes、tapes, coatings, metal sheets, sealants, etc.
1. POLYURETHANE FOAM RESINS Polyurethane foaming resins are designed to expand with water to temporarily block the passage of water through the crack or void .
2. POLYURETHANE RESINS Polyurethane resins are hydrophobic, flexible and used for the non-structural injection sealing and waterproofing of voids, cracks and joints. Their low viscosity allows good penetration into the concrete structure to seal the leaks and achieve a durable elastic seal.
3. ACRYLATE RESINS Acrylate resins are hydrophilic, very flexible and used for non-structural injections of cracks, joints and voids, including for injection hose systems, compartment systems and area (e.g. Grid and Curtain) injection works.
4. EPOXY RESINS Epoxy resins have relatively high tensile and compressive strengths in relation to concrete, they are generally regarded as ‘rigid’ materials and widely used for structural repairs by injections of cracks and voids in load bearing reinforced concrete structures or elements
Injection is a common method used to repair and waterproof concrete structures. It is also used to consolidate and stabilize ground before future structures are erected (pre-excavation grouting) and to stop water and consolidate ground in existing underground structures (post-injection).
