To improve the chance of a successful sound test and reduce the chance of noise flanking you will need to ensure that you allow for the following five acoustic design considerations, when upgrading an existing floors and walls in flats they are: 

  1. Mass
  2. Isolation
  3. Absorption
  4. Resilience
  5. Stiffness

Reasons for party walls failing sound testing in Flats

The are many reasons for party walls failing the pre-completion sound testing for Part of Building Regulations, the main reasons are

  1. Shared Structural Building Components – Floorboards, Floor Joists, Continuous Drywall Partitions, Continuous Concrete Floors, and Cement Block Walls.
  2. Through Structural Steel – Structural steel beams are often a major cause of noise transmission as plasterboard is often fixed directly to the steel without sound breaks.
  3. Plumbing Chases – Junctures between the Walls & Floor Slab Above or at the Exterior Wall Juncture (this should be filed with mortar etc. to add mass to these weakened areas.
  4. Through Windows – if they have single glazing, with no double glazing or secondary glazing as a minimum.
  5. Fixtures & Outlets – Light Switches, Telephone Outlets, and Recessed Lighting Fixtures (if penetrations have been cut back to back with the opposite dwelling under test)
  6. Structural Joints – Perimeter Joints at Wall & Floor, Through Wall & Ceiling Junctures (these should be filled with acoustic mastic.
  7. Around the End of the Partition Through the Adjacent Wall (acoustic mastic should be used to seal this junction)

Acoustic wall upgrade for Existing Flats

One way to quick and simple way improve the acoustic performance of a dividing wall partition, is to install a 70mm met-sec partition in front of the existing wall – it is usually best to install this in the largest room. Leave approx. 25mm gap between the back of the met-sec and the wall. Then install 50mm acoustic wool (min 45kg/m3) to the inside of the met-sec and add two layers of 12.5mm soundboard to the outside of the met-sec frame. Ensure all boards are fully lapped and the perimeter joints are filled with acoustic mastic. 

What Sound Tests do I Need on My Party Walls.

Essentially, for sound testing party walls, you only need to carry out one type of sound test,  which is airborne sound testing. For floor partitions you are required to carry out two types of sound insulation tests which are airborne and impact sound insulation tests. The airborne sound insulation test is carried out by means of a loudspeaker emitting a steady source of noise on one side of the partition (wall or floor) to be measured

How Should I Prepare my Dwelling to Pass the Party Wall Sound Testing?

It is easy to prepare your new project for the sound insulation testing to your party walls, basically you should action the for the following checklist: 

  1. The whole building envelope and internal walls and floors should be fully completed prior to the undertaking sound testing.  
  2. All external and internal doors and walls should be installed.
  3. All electrical fittings must be completely in-place, and fully functional. Poor electrical installation can lead to excess noise.
  4. 240 volt power should be in-place and available in every room. Our testing equipment can be damaged  by the voltage fluctuations of on-site power generators, so it’s essential to have 240V mains supply on-site on the day of the test
  5. No carpets or laminated flooring should be fitted on the 1st floor levels or above. These materials can affect the movement of noise, and as a result could impact on whether a building passes the sound check test.
  6. The skirting boards should not touch the floating floor, a flanking strip should be installed to prevent the noise flanking. 
  7. All gaps in the walls and floors should be sealed. Again, noise can leak out through any gaps, affecting the movement of sound and impacting on the space’s performance.
  8. Access to all of the rooms on all levels should be granted to our technicians, with all noise sources (radios, alarms, building work) ceasing for the duration of the test.
  9. The above points are all essential if we are to achieve accurate sound test readings.  If any of them are ignored, there is a risk of you either failing your test or – at worst – not being able to complete it, at which point you may still be charged 75% of the test fee.

Features of a good locksmith

Human beings value their privacy and security and it is hard to imagine a world without locksmiths where people would constantly feel insecure in their own houses due to the lack of privacy and safety. We all have experienced instances where we were locked out of our own houses, forgotten the password of the electronic security system of our modern house, had a broken key or a damaged lock. These instances are quite common in life and a skilled, professional locksmith is just the person you need when you are facing such issues. We should be grateful for the services provided by locksmiths as without them we wouldn’t be able to feel safe and secure in our own property.

It is important to note that not all locksmiths can provide quality services.  There are also individuals out there who scam people by charging high fees and rendering poor services. Some people run their business by pretending to be professional locksmiths. If you want quality service then you should hire professional locksmiths who are not only well trained but also carry a license such as Best locksmith services in Orlando from LIMU Express locksmith.

Some of the characteristics/features of a good locksmith are listed below:

Availability – Hire a locksmith who would be available whenever you need him because emergencies can strike at any time.

Beginning the Foreclosure Process Among Homeowners

Many people come to us looking for help with very little understanding of the foreclosure process. It is a traumatizing experience to potentially lose the roof over your head so the primary goal of the company is to help build solutions to prevent this unfortunate outcome.

What is a Default that Starts the Foreclosure Process?

The most common default under a mortgage is the non-payment of regular mortgage payments. Legally, the foreclosure process may start after only one missed payment. Other types of default include allowing damage to the property, failing to make tax payments, failing to ensure the property, failing to make condo fee payments, etc.

Typical Steps in the Foreclosure Process

         Below is the step in the foreclosure process.

         • Initial contact

         • Demand letter

How foreclosures work in Alberta

The foreclosure process Alberta is governed by the Law of Property Act. Usually, once 2 to 3 months of payments have been missed the lending bank will submit a file to the foreclosure lawyer of their choosing. The first thing that the lawyer will do is issue a Demand Letter to the borrower (you). This letter acts as a notification that you are in default of the terms of their mortgage. The Demand Letter usually gives 10 days to correct the problem. If the borrower is able to pay the outstanding arrears in full, plus a nominal legal cost, the foreclosure action is avoided. If payment is not made by the date specified, the lawyer is open to file a Statement of Claim with the Court.

 Look at possible mortgage foreclosure options

         •    Taking No Action

         •    Quitting the Claim

         •    Filing for Demand of Notice

         •    Filing a Statement of Defense

         •    Negotiating a Consent Order for Foreclosure

 How to Stop Foreclosure

 Foreclosure can be truly stressful and anxiety-rider times in a person’s life.

      •       Negotiate With Your Lender

      •       Reinstate Your Loan

      •       Forbearance Plan

      •       Sell Your Property

Different rules apply to each mortgage. Usually, a bank is limited to collecting the money that is owed to them by forcing the sale of the property. That allows a bank to force the sale of the property and also sue the property owner for any remaining money that is owed to the bank. The lawyer would be able to help a property owner through the process and explain all of the consequences of theforeclosure based on the type of mortgage.
