Supply and Fixing of Acoustic Glass door with DG UPVC Frame :Frame Size: 90cm x 200cmMaterial: UPVC (Unplasticized Polyvinyl Chloride) Thickness: 50mmGlassOuter Layer:Thickness: 5mm;Type: Tempered glass (also known as toughened glass)Airspace: Thickness: 8mmPurpose: Provides thermal insulation and reduces heat transferInner Layer:Thickness: 5mm; Type: Tempered glass (also known as toughened glass)Double-Layer Glass: The two glass layers (5mm each) are separated by an 8mm airspace, which provides additional thermal insulation and soundproofing benefits.The glass layers are compressed, which enhances the overall structural integrity and safety of the glazing system.Soundproofing: The 8mm airspace between the two glass layers helps to reduce sound transmission and provides soundproofing benefits.The use of tempered glass and the specific design of the glazing system contribute to its sound-insulating properties.Thermal insulation: The airspace and UPVC frame help reduce heat transfer, making the system energy-efficient.Soundproofing: The design and materials used help minimize sound transmission, creating a quieter environment.Safety: The use of tempered glass provides enhanced safety features, such as reduced risk of injury from sharp glass fragments in case of breakage.

Supply and Installation of Wooden Flooring:Supply and installation of a 17 mm-thick wooden floor to enhance sound absorption and reduce impact noise in the designated area, followed by laying carpet.Layer 1: Base with Anti-Vibration PadsPurpose: Dampen low-frequency vibrations from the ground/subfloor. Install high-quality vibration pads directly onto the structural base to decouple the floor frame and absorb structural noise. This initial decoupling is essential for reducing transmission of impact noise upward.Layer 2 : Raised Frame (2″ Height, 1.25 ft² Bays)Purpose: Create an air gap for improved isolation and to support subsequent layers.Construct a grid of frames/raised joists 2″ high, each supporting ~1.25 ft². These act as sleepers and maintain a floating floor—crucial to structurally decouple the finish floor from the building structure.Layer 3: 17 mm Plywood Layer (Screwed on)Purpose: Provide stiffness and add mass for airborne noise control.Fasten the 17 mm plywood onto the raised frames with screws (careful to avoid rigid bridging to the structural base via vibration pads). According to acoustics guides, dense plywood sublayers help block airborne sound Layer 4: 1.3 mm Wooden-Finish Veneer; Purpose: Enhance floor aesthetics and add a thin surface protective/mass layer.Glue or fix a 1.3 mm wood veneer over the plywood.While light, this layerprovides the visual finish you want.Layer 5: 12 mm Acoustic CarpetPurpose: Absorb residual impact sound and improve comfort.Lay a thick, high-density carpet (12 mm deep) on top.Thick carpets with dense underpinning can significantly reduce impact noise — literature indicates carpet-plus-pad systems can halve impact levels compared to hardwood alone.
