5 Timber Separating Floors Introduction By nature, timber floors are low in mass, making them more susceptible to poor acoustic performance and therefore more challenging to ensure compliance. ScreedBoard will add mass and dramatically reduce impact sound transmission at source. The addition of plasterboards, a dry screed board or proprietary screed will add further mass. esilient ceiling bars will de-couple the ceiling and a fibrous slab or quilt will absorb sound in the ceiling void. When correctly installed with a perimeter flanking strip the system will exceed the legislative acoustic standards. Cellecta efurbishment & Conversion Projects Existing timber floors typically have a low mass and sometimes unknown construction details, making them inherently difficult to achieve the prescribed acoustic values without addressing a number of areas. The floor s mass can be increased by the introduction of additional plasterboard layers. Cellecta FIBEfon Micro 50 or mineral wool placed in the ceiling void will defuse airborne sound. esilient bars will de-couple the ceiling, and ScreedBoard can reduce the impact sound at source. Historical Buildings With some historical buildings undergoing a material change of use, it may not be practical to achieve the prescribed sound values. In these cases, Building Control bodies should be satisfied that everything reasonable has been done to improve the sound performance of the structure. Pre-completion tests are normally required and the results submitted accordingly.

21 Ceiling Treatments Introduction The resistance to airborne sound depends mainly on the mass per unit area of the structural floor and partly on the ceiling s construction. It is therefore important to choose a ceiling treatment that complements the performance of the chosen structural floor, to produce an overall structure that exceeds the required db values. De-coupling the ceiling from the structural floor is an effective way of reducing the contact path that impact sound can follow. Adding mass in the way of plasterboard to the floor structure and filling the ceiling void with a mineral wool will also improve the acoustic performance of the structure. Listed below are three types of ceiling treatments available in order of performance. Ceiling Treatment A: Independent ceiling Ceiling Treatment B: Plasterboard on proprietary resilient bars with absorbing material 1.

Proprietary resilient channels Notes (A) The use of a better performing ceiling is permitted provided there is no significant flanking transmission. Professional advice should be sort to ensure the overall floor construction complies with current fire regulations. Further guidance is given in Approved Document E, Section 5 of the Scottish Building Standards and the obust details handbook. The manufacturer of the proposed ceiling system should also be consulted. 1

Videos News New Build efurb More Cellecta Under Floor Heating Introduction In applications such as concrete ground floors where acoustic performance is not essential but an underfloor heating system is to be installed, ScreedBoard 0 is the ideal solution. ScreedBoard 0 features very low thermal resistance properties (0.05W/mk) which allows underfloor heating systems to work at their optimum efficiency. Typically this equates to a 0% increase in the efficiency of the heat pump over using timber based flooring products (i.e chipboard), giving the home owner greatly reduced running cost for the duration of the buildings life. Key Benefits ScreedBoard 0 Low thermal resistance (0.05m /kw) Doesn't contract or expand when exposed to water High impact resistance Interconnecting edge detail - no screws required Quick and easy to install Accepts ceramic tiles FASTACKCAD ACHITECTUAL CAD DATABASES Cellecta App Thermal esistance of Typical Overlay Floor Treatments Scree db oard ScreedBoard 0 outperforms other overlay floor treatments traditionally used in underfloor heating applications

24 Cellecta Eliminating Acoustic Flanking The acoustic efficiency of the floor or wall will be adversely affected should acoustic bridging between the acoustictreatment and the surrounding structures occur (known as flanking transmission). All floor finishes must be isolated from the surrounding walls (including plaster finish and skirting boards), door linings, services and other structural elements. To address acoustic flanking, Cellecta manufactures an extensive range of flexible extruded polyethylene edge strips to suit each specific treatment. DO NOT secure the floating floor treatment to the sub-deck or floor joists. DO NOT sit the skirting board or allow the plaster or plasterboard to make direct contact with the floor treatment. Ensure the acoustic floor treatment is free floating and not fixed to the sub-structure. Use YELOfon flanking strip to isolate the floating floor treatment from the wall and its finishes.
