Fire Retardant Curtain Regulations

Understanding Fire Retardant Curtain Regulations

When working in contract curtain environments it is a legal requirement in various countries for the curtains to be certified to fire retardant standards. In this article, we are going to go through the major fire retardant standards and what is required in different countries and applications.

All of Direct Fabrics flame retardant range is compliant to BS5867 Part2B and some to BS5867 Part 2C.

You can purchase fire resistant curtains here from our range here.

This guide is an overview of the various fire retardant curtain regulations and will be added to overtime.

Further information is included for each particular standard can be found in the links below.

Why do we need flame retardancy regulations

Regulations are quite simply designed to save lives. By ensuring that fabrics and manufactured products conform to the fire retardancy requirements means that customers are safe knowing that the fire risk is reduced and thus they are safer.

Fire Retardant Curtain Standards United Kingdom BS5867

Let's jump in and look at our main market which is the United Kingdom. Domestic curtain fabrics will not normally be flame retardant. Always check the product information to see whether they have the following regulations.

BS5867 - British standard for drapery including curtains and blinds.

This standard covers everything that you require for fire retardant curtains in the United Kingdom.

The standard is broken up into 2 sections;

Part2B which is 10 washes whilst staying flame retardant.

Part2C which is 50 washes / inherently flame retardant.

Areas of use for BS5867

- Hotels, Care Homes, Schools, Hospitals, Medical Centres, Village Halls, Commercial Offices

Fire retardant Curtains Standard for Europe M1 France B1 Germany

When working in the European marketplace the fire retardant codes for France and Germany are M1 and B1 respectivly. These flame retardant standards are similar to the United Kingdom BS5867. The main difference is teh M1 standard is a very high level of flame retardancy. Usually but not always a fabric that conforms to BS5867 Part 2C and is inherently flame retardant will pass the higher regulation of France M1.

Getting fabrics tested to flame retardant standard M1 has to be done in France as the French testing house are the only locations that are certified to perform the M1 Test. This means it can be quite expensive to get this product tested and will involve sending fabrics overseas to get them tested.

The M1 test is a vertical test to see how the flame spreads across a panel of fabric over a duration of being ignited.

You can review a more indepth review of the M1 and B1 standard here

• B1 (DIN 4102 B1)
  German Flame Retardancy Standard for flame retardant building products. Materials that have been finished in accordance with B1 must self extinguish after the ignition source has been removed.
• M1 (French Flame Retardancy Standard)
  Corresponds approximately to the German DIN 4102 B1.

Areas of use for M1 B1

Understanding Acoustic Curtains - Absorption vs Insulation

Understanding Acoustic Curtains and Which is Best for you Absorption vs Transmission (Insulation)

MUST READ INTRODUCTION

Before commencing this article, we are going to be looking at the difference between 2 elements and why buying products on the internet knowledge on a subject assists you in understanding which product is best for you. The 2 different areas when it comes to acoustic curtains. Absorption and the other is insulation.

Sound Absorption is used to reduce echoes and sound going around a space See part 1

Sound Insulation this is to stop sound from passing / entering into a space. See Part 2

READ THIS

Most curtaining products out there in  the market place are beneficial to sound absorption and will have very little impact on sound insulation.

Sound Absorption – Acoustic Curtains

When working with loud echoes in spaces it can be incredibly frustrating to stop sound reverberating around the room. This is where acoustic curtain come in. Depending on the fabric it will have a varying effect on the amount of absorption that It takes and effects the sound passing back around the room.

To see how good a fabric or product is at absorbing sound in a room then you need to complete the

Sound absorption test EN ISO 354. This grades a product between A – E based on how absorbent a material is. When sound is projected into a room it will hit the surfaces and then it will either be transmitted through things like ceilings and walls or it will be reflected back into the room. So in a basic form the test is how much sound is sent out will return.

Example Imagine. 100 units of sound are sent into a room, 80 units are transmitted out of the room and then 20 are recorded back in to the space.

Thus the sound absorption coefficient is 0,8.

Α = converted Energy +  transmitted energy in relation to the incident.

Incident is the sound initially sent out.

The main aim of materials hung around rooms like recording studios and theatres is to stop the sound reflecting back around and ruining the transmission of the direct sound.

By having fabrics that are highly graded like black wool serge and expression dimout fabric you are limiting the amount reverberation back into the room. This is extremely important for recording studios and also quiet spaces like offices.

Imagine being in a large gymnasium with concrete blocks all the way around the room. If you shout you will get a large amount of echo

Which Fabric is Best for Sound Absorption.

Overview Direct fabrics will continue to add to the testing list. Direct Fabrics will add additional fabrics as demand for fashion products increases. However the expression product testing has a gorgeous herringbone running through the fabric and the team feel this is a perfect example of

Working with a variety of suppliers we have tested some fashion dimout products aswell as wool serge materials.

The core product for theatres, exhibition centre and performance centres is black wool serge material. This is a chosen due to being cost effective and performance grading of A / B depending on fullness.

Direct Fabrics is now recommending a designer fabric called Expression which is dimout so 90+% light stopping, this means that you get the highest sound absorption and also a beautiful finish with a herringbone effect for a price lower than a coloured wool serge.

Deciding which fabric to purchase

Very simply you have a choice of a low cost black wool serge for a quick and effective drape to reduce the transmission of sound around a space at different frequencies. Or you can use a decorative product that is slightly more expensive that will give you even more than the standard wool

Sound Insulation Curtains – To be complete 2019

This subject is particularly difficult to quantify, and all environments will differ.

A particularly good analogy I like to use when thinking about partitions and blocking sound is when you are driving in your car. You have the windows closed and it is quite quiet but as soon as you open the window even as much enough to slide an envelope through you can hear a large amount of sound. This is because sound is like a liquid and flows to wherever there is a gap. It will bounce off surfaces until it finds a route to go.

When deciding to look for a sound insulation fabric it all comes down to the mass of the product and that it is tightly woven and doesn’t allow anything to pass through it. A common product is mass loaded vinyl. BUT when making curtains from this product you will have a gap around the curtain so although you will see a reduction you will not

What is mass loaded vinyl

Mass loaded vinyl is a heavy weight vinyl product that has a weight generally of between 5kg and 10kg and is ideally suited for stopping airborne sound. It has a greater weight than lead and will be perfectly suited to stop sound passing between spaces when full enclosed between objects. It is usually used a floating wall barrier between stud work and pasteboard for cinema rooms, but Direct fabrics has been trialling this in curtain form. As a barrier it is shown to reduce sound transmission by circa 20db and 30db.

Understanding Sound Transference / Sound Blocking

It is a common misconception that having foam egg carton shapes on the wall will stop sound coming into a wall. This is simply incorrectly. Imagine sound as water, if you made a wall of sponge do you think that it will stop the water passing through. No it wont. Then imagine an aquarium tank made of thick glass, sound will work in the same way as glass and it will stay within the tank. This is the same with sound passing between spaces.

From Direct Fabrics investigation and speaking with sound labs. We have discovered that the best product for reducing sound transmission is a product that acts as a ridgid barrier.

So using an MLV combined with an absorbtion fabric will give an excellent sound reducing curtain. However it should be known that even having a super thick layer of MLV or similar fabric will still let sound pass through any air gaps.

Please speak to the direct fabrics team for specalist products that will work for you windows for a complete sound solution.

6 Steps to Choosing Hotel Curtains

6 Important Steps to Choosing & Installing Curtains in Hotel

Quick Overview to 6 steps to buying hotel curtains for your hotel project

In this post we are going to go through the various options to hotel owners that are looking to improve the window furnishings in their hotels and what the most important steps are in ensuring the hotel has the best finish

From working with clients in various hotels from 2 star bed and breakfasts all the way up to prestigious 5* hotels including the Sheraton / Marriott and Hilton. Direct Fabrics comes across various stumbling blocks that need to be covered before purchasing.

STEP 1. Ensure you get the correct measurements of the windows

A huge mistake time and time again is that the house keeping or management team don’t take the time to get a quality site survey taken. The old saying “Measure Twice Cut Once” this is imperative here. Ensure that you measure all the various options and document the information clearly.

Before you begin you can download our site survey form and this can help you with ensuring everything is document clearly.

Measuring is usually the downfall of most projects and this is usually only found out once the items that have been purchased or manufactured are ready for installation. It is common to have to remake or even adjust products that have been measured incorrectly.

Curtains have an added benefit when being measured for a track, if you measure too big, curtains have a tolerance as there will be fullness in the curtains. This means you can pull up the curtain tapes more or when using eyelet curtains just have more pleats on the track or poll.

With a drop for blinds or curtains, there will be little to no tolerance, always better to be slightly too long as the puddled look of curtains will look more decadent, however in a modern room may look odd.

Rule of thumb when measuring a window.

***** Go 15cm past on each side of the window recess – therefore 30cm total

*** Go 15cm above the window and then finish at the desired length.

Step 2. Selecting the Look for the rooms

Go through various room shots that you find appealing and understand which treatments are required for the best finish and what is expected for your level of accommodation. For instance a 4 star hotel is expected to have a very high level blackout. There for you need to ensure that the curtains have a 3 pass blackout lining and minimal light seepage around the application whether it is a blind or curtains or a mixture of both. For the most blackout a curtain will provide a significant increase over a roman blind.

Note that roman blinds by design will ware a lot quicker than curtains as the rods and stitching endue a significant amount of pressure and can eventually break particularly on larger roman blinds. When using roman blinds Direct Fabrics only supply child safe chain operated mechanism.

Also be aware of the robustness of different applications using curtain tracks spreads the weight across the window where as a curtain pole will mean by design there are less brackets than a track and also because they have an angle to the bracket that if pulled on an angle they will loosen and come out of the wall.

Step 3 – Ensure you are buying Flame Retardant Soft Furnishings

In the United Kingdom / Europe / America commercial spaces are required to have flame retardant fabrics that are certified to the required standards. This means that you need to work with a contract furnishings company that has market knowledge and can supply curtains and fabrics to BS5867 in the UK, NFPA for America and M1 and B1 for Europe.

This doesn’t have to limit the range on offer it just means that “Safety is First”. It is paramount when running a hotel to know that you are operating within the law and you can abide by your insurances. There is nothing worse than thinking you may be operating with inferior window furnishings, particularly with so many high coverage events that have ended in tragedy.

Flame retardant soft furnishings have thousands of fabric options, varying from Dimouts, Blackouts / Prints / Wovens / Voiles and more.

Direct Fabrics offers a large range and can source and supply fabrics from around the world. If you have seen a designer fabric then

If you want more information on the various flame retardant standards then you can read them at the links below.

Step 4 – Choosing a colour palette and design

When choosing the design for a hotel room it can become quite complex, at Direct Fabrics we are finding time and again that hotels are preferring to use a plain curtains and bring colour to the room with accessories. This means that the rooms do not date quickly. Modern grey colours are extremely popular presently for hotel interior design.

STEP 5 – Choosing the right manufactures and price point

The old saying you get what you pay for means that you will have a huge variety of prices and for those you will get varying amounts of services.

Highest – Full Interior Design service including manufacture and installation

Middle – Online Contract Furnisher with local coverage. Choose your fabrics online and get samples, Manufactured and installed as necessary. Perfect example is www.direct-fabrics.co.uk

Low – You choose a fabric and put all the pieces together, using a seamstress and fabric suppliers being direct from the contract furnishing supplier or from a local retailer. NOTE – ensure that your fabrics are compliant to the required laws.

STEP 6 – Installing and Dressing

When it comes to installing in a commercial environment it is imperative that your curtains and soft furnishings are fitted and dresses to the highest standard. The fixings of the curtains, poles and blinds needs to be secure and strong enough for residents of the hotel / guest house to abuse daily. The residents in a hotel expect everything to work without issue or there is a potential for the guest to requests discounts or refunds. So the hardware needs to work perfectly without issue.

Ensure that the fixings are strong and secure. In an ideal world go through the plaster into the block behind. Use hardened drill bits to drill into the toughest blocks and steel.

Once the hardware is up and operations and good idea is to use a SILICON SPRAY to lubricate them so the glider move beautifully and with the gentles of touches.

Dressing curtains ensure that you use metal hooks, Direct Fabrics pre pull and hook all taped curtains. This means that you can unfold and then clip into the glider on a curtain track or on to the rings of a pole.

Suspended Ceiling Curtain Track Options

When faced with an awkward space it is always best to plan your approach for fitting curtain tracks and other hanging elements. A particularly difficult space to fit to is suspended ceilings. Lets go through the various information to try and assist you in your decision in buying a curtain track for your suspended ceiling.

What is a Suspended Ceiling

A suspended ceiling is a ceiling that has been installed below the standard ceiling for a space. The void created is usually used for services including air conditioning, wiring, plumbing and other elements that are needed usually in commercial sites for quick and easy access. Usually these suspended ceiling are created from a grid system that is made from a metal aluminium frame that is durable and sufficiently strong to hold the tiles plus any additional weighting.

The framework is the crucial part of whether it is possible to suspended additional weight from the tiling sections. 

Main Suppliers and Manufactuers

Armstrongs

Rockfon

Epifon

British Gypsom

A standard weight tolerance for these is 10kg per metre squared.  Remember that when the curtain is pulled along the track it weight will be evenly distributed across the track.

Direct Fabrics recommendation is to use our cubicle curtain track for a hand drawn option. This is so that you can put the majority of the weight of the curtain on the wall shoes when the curtain is drawn back.

Areas to Consider when fixing to a suspended ceiling

The weight tolerance of the ceiling grid is the main area of risk when fitting to a ceiling grid. The grid must have been installed correctly to enable it to hold the required wait of additional fixtures and fittings.

First Question that need to be asked. What is the weight capacity per metre squared of the grid?

Curtain Weight Calculations

What is the weight of my curtains. This can be calculated by knowing the full length of the curtain and doing some calculations. eg. Curtain width 400cm x Drop 200cm = 8sqm. Then knowing the fabric weight. Eg Venus fabric 280gms plus lining 200gms = 480gms. Then multiple the 2. 8 x 0.48kg = 3.84kg for the curtain.

In the picture to the left it is not a suspended ceiling but you can see that the curtains are drawn back to the wall where the wall shoes are located this means that the weight is passing through the wall not the ceiling brackets.

Fixing Curtain Tracks to Suspended Ceilings

When fixing to a suspended ceiling there are 2 options to consider.

Should i fix to a noggin above the ceiling tile?

or should i fix all the way up to the concrete or solid sealing above?

It all comes down to the weight that is going to be going through the wall and the ceiling tiles. If the weight of the curtains is our standard cubicle curtains then a standard setup will be fine using the noggin as the curtains have been chosen due to their construction of 220gms curtain fabric.

Which Tracks are Compatible with Suspended Ceilings

The majority of top fix curtain tracks are compatible with suspended ceilings. If there is considerably more weight going through the track it is advisable to use a track that can also be mounted the wall shoes on each end in order to distribute the weight more effectively across the track.

The curtain track that we recommend is the cubicle curtain track as it can have long expanses without many brackets and takes the majority of its support from each end. The cubicle track can have upto 3m without any central supports at all. It is hand operated and can be purchased here

School Hall Curtains

Introduction to the Client

http://www.churchdownschool.com/

Work Requested for School

The client is a prestigious school. They have decided to upgrade the school hall curtains. Previously fitted was very old vertical blinds and roller blinds to provide a standardised shading solution. However by nature blinds as a solid structure are not very good for acoustics. It was decided to use a flame retardant velvet material that was a tiviera, this meant that it could be washed and continue to be flame retardant.

The tracking needed to be installed on the high slit windows all the way around the assembly hall of the school.

Products Required

The curtains were manufactured with a robust 3" pencil pleat heading, the curtain tracks installed were a combination of corded tracks that were child safe for the high windows and hand drawn heavy duty tracks for the lower windows.

Introduction to the Client

Work Requested

Initially the products requested we flame retardant Roman Blinds in a Creation Baumann fabric that had been specified by the groups architect. However when evaluating the suitability of using full length roman blinds over 350cm, it was decided that they would have issues over time due to the inherent defects caused by using roman blinds. Roman blinds on long length put too much strain on to the stitching. Also having chain mechanisms in a high traffic aread gives the opportunity for misuse. Based on this the decision was made to use a simple tracking system with draw rods and a wave heading option for a clean finish.

Understanding Flame Retardant Standard European EN 13773

What is EN 13773 - 1,2,3 Flame Retardant Standards – European FR Standards for Curtains

EN13773  is the European flame retardant standard for contract drapery. This is the latest flame retardant standard for drapery and links in with old tests such as BS5867, M1 B1 and other drapery flame retardant tests. It has been introduce

By using the EN 13773, this interlinks and unifies the results across Europe for testing purposes for 1 market.

Composition of Fabrics – Flame Retardant Standards Europe

Understanding which fabrics pass which tests is important as you can have inherently flame retardant fabrics such as Trevira which are polyester fabrics with the flame retardant yarn so they do not need to be treated. This means they can be washed and they will keep their flame retardancy. Some fabrics that are treated will need to be retreated if they are not inherently flame retardant. Therefore a user needs to be mindful that after dry cleaning they may no longer be flame retardant.

Areas Used

The European flame retardant standards will be required in any commercial environment, a hotel will require EN13773,  M1 B1 standards in Europe and BS5867 in the UK. They are all similar tests but it is required for insurance requirements to ensure that they are certified to avoid any legal risks.

Understanding Different Fabric Flame Retardancy

Durably Flame Retardant

Again these fabric have been chemically treated and will be suitable for washing.

Inherently flame retardant

An inherently flame retardant fabric is made from a yarn that has the flame retardancy already within the yarn like a Trevira. This means it can be washed multiple times and not loose its flame retardancy.
