What is the Hush Cem Panel 28?
The Hush Cem Panel 28 is an advanced acoustic floorboard engineered to improve soundproofing in lightweight buildings. It features an 18mm tongued and grooved cement particle board bonded to a 10mm Hushfelt resilient layer, making it a high-mass solution for reducing airborne and impact noise. This panel is ideal for projects requiring enhanced sound insulation, particularly in structures where standard acoustic flooring may fall short. Its innovative design ensures it adds significant mass without the need for excessive height, making it perfect for spaces with height constraints.
How Does the Hush Cem Panel 28 Work?
The Hush Cem Panel 28 combines the principles of mass and resilience to tackle noise transfer effectively. The high-density cement particle board increases mass, which improves the ability to block airborne noise. Meanwhile, the Hushfelt resilient layer decouples the panel from the subfloor, absorbing vibrations and reducing impact sound transmission. Together, these components create a floating floor system that isolates sound and vibration, delivering superior acoustic performance. By adding mass to lightweight constructions, the Hush Cem Panel 28 also improves airborne noise insulation, which is challenging to achieve with standard flooring solutions.
What is the Hush Cem Panel 28 Made Of?
The Hush Cem Panel 28 is constructed using premium materials to ensure durability and performance:
18mm Cement Particle Board: This dense, moisture-resistant board provides the mass needed for effective airborne noise insulation and creates a stable surface for floor finishes.
10mm Hushfelt Resilient Layer: Factory bonded to the underside, this layer absorbs vibrations and impact noise, forming an essential part of the panel’s acoustic performance.
This combination of materials results in a robust and reliable acoustic floor panel that meets Building Regulation Part E requirements and contributes to sustainable construction practices.
How Effective is the Hush Cem Panel 28 at Stopping Nuisance Noise?
The Hush Cem Panel 28 is highly effective at reducing both airborne and impact noise, making it an excellent choice for various construction projects. Its high-mass design enhances airborne noise performance, addressing a common challenge in lightweight buildings. The resilient Hushfelt layer dampens vibrations, reducing the transfer of impact noise caused by footsteps or dropped objects. The panel has been tested to exceed Building Regulations Part E (England & Wales), Section 5 (Scotland), and Part G (Northern Ireland), ensuring compliance with stringent acoustic standards.
Where Can the Hush Cem Panel 28 Be Used?
The versatility of the Hush Cem Panel 28 allows it to be used in a wide range of applications:
Refurbishment Projects: Ideal for upgrading the acoustic performance of existing lightweight structures.
New Build Developments: Suitable for timber and concrete subfloors in residential and commercial properties.
Multi-Storey Housing: Effective in reducing noise transfer between floors in apartments and flats.
Lightweight Constructions: Perfect for enhancing sound insulation in buildings with minimal mass.
Structural and Overlay Applications: Can be installed as a floating floor or directly over joists with the use of joist strips.
How to Install the Hush Cem Panel 28
Preparation: Ensure the subfloor is clean, level, and free from debris.
Layout Planning: Arrange panels in a broken bond pattern, avoiding cuts smaller than 150mm. Leave a 10-15mm gap along all perimeters for isolation.
Install Perimeter Strips: Use Hush Seal 20 or Hush RD Flanking Strips to isolate the panels from the walls and create an airtight seal.
Position Panels: Lay the panels with the Hushfelt side facing down, ensuring a snug fit between joints.
Glue Joints: Apply Hush Cem Adhesive to all tongue-and-groove joints, ensuring a strong and seamless connection.
Mechanical Fixing: Avoid using fasteners that penetrate the floating floor, except where two panels with cut edges meet, such as door openings.
Finishing: For skirting boards, leave a 2-3mm gap above the panels and fill with Hush Acoustic Sealant for optimal results.

I called Soundstop with lots of questions and the person I spoke with was extremely knowledgeable and helpful. I ended up purchasing soundproofed plasterboards and genie clip system from them
Two alcoves with independent stud walls built and insulation/clips installed.
The result? It works, was sceptical it would,so it was a gamble, sound reduced from neighbours is 70% less and now feel like our semi detached house is more like a fully detached! I’m glad I did it, took me 2 days in total.
All products for a LB2 soundproof ceiling are as expected and delivered on time. The advice given before ordering and before installation was second to none. The guys at soundstop really care that your project goes well. Can't recommend them enough!
From query to delivery always a pleasure to do business with. Can recommend enough. We have used both the standard and advanced (sbx) sm20 systems and they have both made a huge difference in a mid terraced house.
Soundstop are truly amazing at what they do. As a DIYer I need help and advice lots and the team are always there to help out.
The products themselves are top quality and worth of any recording studio never mind my party wall!
Keep up the good work!
The service from the team at Soundstop has been amazing. Jim advised me in the early stages and took my thinking to an end design which is now installed and working beyond my expectations Thankyou
Soundproofing a wall in a factory by a sandblasting booth
The items I have purchased from soundstop have been very useful in the application used to carry out the job requirements on the job that had to be done, the service from Lucy and Jim have been outstanding would use soundstop and would certainly recommend there services to another company or individual
All-round excellent service. Had a phonecall to confirm order minutes after making it online & had further calls keeping me updated on delivery. Very friendly & were more than happy to give some advice when needed.
Genie clips & bars were simple to install & there's good articles on the website for reference. Haven't heard anything from my neighbours yet!
I'd like to thank the team at Soundstop, they completely exceeded my expectations. The customer service is second to none and the delivery was on time as agreed. Very highly recommended.
I don’t think in nearly 23 years I’ve ever dealt with a company so efficient, knowledgeable and helpful! Delivery was very quick. When I needed some technical assistance, Jim was more than helpful. So much so that I felt I should’ve paid him a consultancy fee! Such a pleasure to do business with Soundshield. Amazing!
Very helpful, in helping us to what we needed to order, to soundproof our wall, it all arrived on time, first class service, will be using them again, Thankyou soundproof, for all your help.
My experience of phoning Soundstop for general help with soundproofing and specific help with their products has been a unique experience. A genuine desire to help backed up with the actual knowledge to be so.
I just wish all support calls could be so fruitful.
We had great telephone support whilst choosing the product. We bought Tecsound 70 which was easy to fit ( following the good instructions ) It is a great product and seems to work well. The carpet fitter was amazed by it and the shop are now interested in knowing more! Would recommend both Stopsound and the product
