Sash Window Care and Operation Guide

Sash Window Care and Operation Guide

The sash window or vertical sliding window was the most
ingenious product of the seventeenth-century and has found
acceptance by over half the western world.
Sash windows have influenced the architecture of buildings for
more than two centuries and the whole design of buildings was
constructed around the grace and dignity of the sash window.
The traditional appearance and the operational effectiveness
including some refinements have been incorporated into
today’s modern PVC-U sash windows.

Unlocking the window -
If you have key locks, insert the key into the locking cam catch and turn to unlock.
Turn the cam catch anti-clockwise through 180 degrees to open.

Limit Stops - Some windows may have limit stops fitted on the top sash. This opening restrictor allows for the top or bottom sash to be opened to a set position of 100mm. This needs to be pressed in or locked in position using the black nylon key provided to allow the sash to travel past it.
You will now be able to slide the sashes up and down freely.

Ventilation - Vents can be fitted to the top rail of top sash. If fitted slide the cover sideways to open the vent to the desirable position. Care should be taken that the bottom sash does not contact the vent as this may cause damage to the internal vent cover. If you have K3 two stage keeps fitted you can lock the window closed or slightly open for ventilation.

All about cleaning your windows & operating the tilt facility (if fitted)

The most significant difference between the modern PVC-U sash window and its traditional window equivalent is the tilt facility that enables safe cleaning from the inside.

PVC-U should be cleaned at periodic intervals to maintain the original pristine appearance. The frequency depends on the geographical location and the local environment but as a general rule the frame should be cleaned whenever the glass is being done.
1)Slide the bottom sash clear of the cill up-stand. This releases the interlocks that prevent drafts from between the top and bottom sash.
2)Slide the tilt knobs towards the centre of the sash (tilt knobs are located on the top of the bottom sash at either side).
3)Gently pull towards you until the tilt rest arms on the side of the sash engage and take the weight of the sash.
- The top sash can be operated in the same manner when the bottom sash has already been opened. 4)Wipe over the plastic profiles with a damp cloth, working from the top of the top sash to the bottom of the bottom sash.
5)Clean the glass using water based glass cleaner or soapy water. NB: When cleaning a window it can be difficult to clean the external travel stops. Should you be tempted to remove for cleaning, do not slide the sash as the balances can be overstretched and thus permanently damaged. After closing the sash, give a slight pull towards you to ensure the sash has latched into the frame properly.

• Wipe the white rubber seal on the bottom of the bottom sash to maintain a good white finish.

 • Ensure the drainage holes located on the bottom of each sash are clear to allow for drainage.

• Clean the grey brush pile to ensure good seal against drafts.

• Use silicone spray or a beeswax polish to lubricate the sliding components. If the window starts to stick or squeak, NEVER use oil based products on your sash windows.

• Clean the outside pane of the top sash first. When complete, return the sash to a vertical position and then clean the inside pane.

Apply the same procedure to the bottom sash. After cleaning it is absolutely essential to check all tilt latches have re-engaged. Do not forget to reset any Limit Stops after cleaning

What chemicals to use to clean the PVC-U?
The best method of cleaning is to use a clean cloth and a solution detergent such as Flash or Fairy liquid diluted to the normal concentration for floor cleaning or washing up.

If the surfaces are excessively dirty or unsightly and stains remain, then a mild nonscouring cream such as Cif can be applied.

Most suitable window cleaning detergents are probably already in use in the majority of households.

NB: Avoid at all times solvent based cleaners and abrasive materials because of scratching and especially the use of steel wool pads as these may cause permanent scratches. If you follow these instructions your windows will look good and operate as well as the day they were installed.

Trickle Vents - Meeting regulations

The Building Regulations in England and Wales require ‘that there shall be adequate means for ventilation provided for people in the building. It however now differentiates between windows for residential installation in either a Replacement or New build application.

Replacement windows

If the window being removed has trickle vents fitted, then the replacement window should also have them – to the same level of performance.

The ventilators fitted to the replacement window should therefore offer at least the same capacity as the ventilators fitted to the removed window.

Typically these ventilators will be either 4000mm2 or 2000mm2 in their geometric free area.

Where it is not possible to ascertain the capacity of the outgoing vents;

• Habitable rooms should have a minimum of 5000 mm2 EA*
• Wet rooms should have a minimum of 2500 mm2 EA*

*Equivalent Area EA, figures will vary for Scotland, Northern Ireland and Eire.

If the window being removed did not have trickle vents fitted, it is recommended to provide the background ventilation in the replacement window, due to the health benefits.

Additional Guidance for Replacement Windows within England and Wales

The Building Regulations Requirement F1 – Means of ventilation, states:

There shall be adequate means of ventilation provided for people in the building.

When assessing a property for replacement windows the following should be considered regarding the use of trickle ventilators and other forms of ventilation within replacement windows:

• Trickle ventilators are not mandatory unless the existing windows have them, however it is always good practice to consider their use when replacing windows. Alternatively ventilators may be replaced by an air brick.
• Replacement ventilators must be no smaller in geometric open area than the existing ventilators. If the geometric area is not known, habitable rooms should have trickle ventilator of 5000mm2 equivalent area and wet rooms should have 2500mm2 equivalent area.
• Although not mandatory, increasing ventilation by the provision of new or additional ventilators to maintain good air quality should be considered between the supplier and the customer (ref: GGF publication “Advice to consumers regarding ventilation when replacing windows”).
• Two stage locking handles are an acceptable form of trickle ventilation, where security is not compromised and draughts will not create a problem. This would usually mean not on the ground floor.
• The provision of permanent ventilators for combustion appliances is a different matter and compliance with Approved Document J is mandatory

New Houses

Ventilation levels within a house or dwelling are dependant upon a number of factors. Guidance tables can be found within Approved document F – or alternatively ventilator manufacturers maybe able to assist.

England and Wales

Basic requirement is 5,000 mm2 EQA for a habitable room.
Overall calculations are by floor area.

Total equivalent ventilator area (mm2) for a new dwelling with any design air permeability (EQA)

Total equivalent ventilator area (mm2) for a new dwelling with a designed air permeability leakier than (>) 5 m3/(h.m1) at 50 Pa (EQA)

This is based on two occupants in the main bedroom and a single occupant in others. For a greater level of occupancy, assume a greater number of bedrooms. For more than five bedrooms, add 10000 mm2 per bedroom.

Building Regulations Part F (England & Wales)

A systems approach

Due to the increasing complexity of the Regulations, ventilation strategies and system design must be considered at the earliest stages of building design.

3 three ventilation types:

"Whole Building" background ventilation to provide fresh air to dilute and disperse low levels of water vapour and pollutants, usually by the provision of background ventilators or mechanical supply ventilation.

"Local extract" extract ventilation in rooms where most water vapour or concentrated pollutants are released.

"Purge" rapid ventilation for the rapid dilution and removal of high concentrations of pollutants from occasional activities, usually by opening windows as set out in Appendix B of Part F.

Approved Systems of Ventilation

Background Ventilation & Intermittent Extract:

This method requires background ventilators with at least 5000 mm2 EQA in habitable rooms with external walls and a combination extract and background ventilators with at least 2500 mm2 EQA installed in wet rooms.

Passive Stack (PSV) & Background Ventilation:

This method requires the installation of a stack system into wet rooms/kitchens with background ventilators with at least 5000 mm2 EQA fitted in all habitable rooms with external walls and background ventilators with at least 2500 mm2 EQA installed in wet rooms not containing PSV units. Open flued appliances still require air supply as given in approved document J.

Continuous Mechanical Extract Ventilation:

Continuous mechanical extract ventilation is an alliance of a central extract unit and trickle ventilators to ensure fresher air is drawn through the property. All habitable rooms require 2500 mm2 of equivalent area to ensure property does not dry out.

Continuous Mechanical Supply & Extract,with Heat Recovery:

No requirement for trickle vents.

The performance for each “System” approach set out in Part F are the minimum requirements needed. The occupant’s health could be at risk if they are compromised.

Systems may be manually or automatically controlled. For each system air must be able to flow through the dwelling. The Regulations make provision for this via internal door undercuts to maintain a minimum gap of 10mm above the finished floor. This provides a 7600mm2 permanent opening when a door is closed.

E.g. System 1 – Intermittent extract fans and background ventilators. This is the most commonly used system in the UK.

Where can it be used?

It is suitable for use in houses and flats or apartments with multiple façades. In some circumstances, especially in dwellings with a single façade.

How does it work?

The system comprises of background ventilators, fitted to windows and extract fans fitted in moisture producing areas or “wet rooms” (kitchens and bathrooms). The background ventilators provide the whole building ventilation and also supply air to the intermittently operated extract fans which provide the extract ventilation.

How are ventilation rates calculated?

Guidance on minimum provisions for extract and whole building ventilation is set out in tables of Approved Document.

The whole building ventilation rate for background ventilators is determined by a number of factors:

• Dwelling floor area
• Number of bedrooms, occupants, storeys and number of façades.

What benefits does it offer?

• Simplicity
• Operation familiar to most occupants
• Straightforward installation
• Inhabitants control

What difficulties could we encounter?

• Perceived high running costs
• Noise potential of low quality or poorly installed fans
• Single façade dwellings require additional background ventilators fitted at low level

Specific Ventilator requirements - approved F1 revised document 2006

• Ventilator areas are now described in terms of equivalent area, as opposed to the geometric measurement.
• Where replacement windows are fitted, these must have Ventilators if the old units contained them. Ideally vents should be fitted in all cases.

Performance-based Guidance introduced

• What level of ventilation should be sufficient, rather than how it should be achieved.
• The designer has the freedom to use whatever ventilation provisions suit a particular building.

Standard Requirements

• All Vents to be Marked with Equivalent Area in a visible location.
• All trickle vents must now be tested to BS13141-1:2004.

Ventilator Location

• Ventilator should be typically located at 1.7 metres from finished floor level, this is to avoid the potential discomfort of draughts.
• Single façade properties where both ‘High’ and ‘Low’ level ventilation is required, low level should be approx, 1 metre below the high level ventilation.
• When using intermittent extract fans, the frame vent should be located at least 0.5 metre’s from the extract fan.

Vent opening configuration and method used to calculate equivalent area @ 1Pa.Tested to EN 131141.

• New Build Dwelling – The trickle ventilation requirement for a house is based upon the overall floor area and number of bedrooms. (Dependent on ventilation method used.)
• Existing Dwellings – Trickle ventilators supplied in all rooms, 5000mm2 minimum in habitable rooms, 2500mm2 in wet rooms.
• Regulations now apply to Conservatories and Extensions

TOP TEN TIPS TO BEAT CONDENSATION

TIP 1:

Keep your home well ventilated by opening windows every day. You should also make sure that the drip vents in your windows are open as these allow additional airflow that will combat condensation. If you have condensation on windows it is likely that it will be elsewhere in your property too.

TIP 2:

When you are cooking always turn the extractor fans on in the kitchen on a high power. This will extract any excess moisture from boiling pots and pans. If possible, open up the kitchen windows whilst cooking for extra ventilation. It is an idea to leave the extractor fan on for longer than you are cooking as there will be excess moisture in the air which you cannot see.

TIP 3:

After taking a bath or shower there will be excess moisture in the air. To stop condensation forming, the bathroom windows should be opened and extractor fans turned on. Try to keep the bathroom door shut as much as possible so the moisture doesn’t escape into other parts of your home.

TIP 4:

When you are drying your clothes you should dry them outside where possible. If you cannot do this then put them in an enclosed room and keep the window open. If you use a tumble dryer to dry your clothes it is extremely important that the ventilation pipe runs to the outside of your property.

TIP 5:

You should leave a small gap between the walls of your home and your furniture as this allows the air to move away from the bottom of the walls and circulate around the room. If air lingers between the furniture and walls it will condense onto walls and could eventually form into black mould

TIP 6: 

Your property’s airways such as airbricks and chimneys should be clear to allow airflow in and out of your home. Air ventilation is extremely important as you don't want moist air to be trapped in one part of your home as it will condense on your walls.

TIP 7: 

During the winter and at other cold times of the year you should try to maintain a constant temperature in your home. This is because it is cold air that causes the warm air to release moisture. If the air is all the same temperature then this cannot happen

TIP 8: 

Always keep the lids on pots and pans whilst cooking so that the moisture does not escape from the pans. If the lids are off moisture will be rising from the pans even if you cannot see it. Just as you can only see your breath in the air on a cold day, you can only see the moisture rising from a pan when the temperature is lower.

TIP 9: 

Check your roof to see if there are any problems such as water leaking in.

TIP 10: 

Check the guttering and down pipes, make sure that they are carrying the water away and that there are no damaged/blocked guttering or drainpipes causing the external wall to become soaking wet.

8 Things to Know About Windows

1. Leaky and inefficient windows, and glazed doors account for more than 25 percent of the average household's energy bills. You can cut energy costs by as much as 15 percent by buying double glazed windows.

2. Cut noise with insulated or double-glazed windows featuring 1/4 inch to 1 inch of air (or argon) between the panes. Wider air spaces and thicker glass reduce noise more.

3. Useful Life: Most manufacturers say windows should be replaced after about 20 years. Signs of a failing window include being sealed, draftiness, and panes that collect condensation, ice, and frost.

4. Aluminum: Strong, affordable, and low-maintenance, but conducts heat and cold.

5. Composites: Stronger and more durable than wood and vinyl, and priced between the two; can be painted to match a home's decor.

6. Low-emissivity (low-E) glass has a thin metallic coating that reflects heat back to its source, keeping heat inside the house in the winter and out of it in the summer. Low-E coatings also reduce energy costs and block UV rays while allowing 95 percent of natural light to pass through

7. Maintenance free – Most manufacturers today offer an exterior window that requires little or no maintenance. Other than cleaning and inspection of the caulk joints on an annual basis, you should enjoy many years of worry free maintenance to your windows and trim. Windows made of vinyl, fiberglass, composite material, aluminum clad wood, vinyl clad wood or all aluminum will provide you with varying degrees of low maintenance. Most will eliminate the need to paint on a regular basis which will save on your painting bills.

8. Aesthetics – New windows can provide a new or updated look. They also can match your original home and blend in architecturally while providing energy saving benefits. Many manufacturers feature multiple color choices for the exterior and hardwood interiors for that special look. Grid options or style of window give you the opportunity to totally change the look on the outside. There are so many new options for color, hardware, grids, and interiors now available that you can truly personalize your windows to match your individual tastes

Windows and Doors

Introduction

If you are thinking about changing your windows or doors you will need to think about U-values. A U-value measures of the rate at which heat escapes through a fabric, so the lower the figure, the better.  A U-value of zero means that no heat is escaping.  It is expressed as Watts per square metre (W/m²) but it is really only the number that matters. 

Double and triple glazing

Double or triple glazed windows are another form of insulation. However, as you can see from the figures below, it is not generally so efficient as wall and roof insulation. Replacing a single-glazed window with a reasonable quality double-glazed unit will more than halve the heat loss.

The Energy Saving Trust estimate that you will save £165 a year by replacing single glazed windows with B-rated double glazing. You will also reduce noise from outside, and experience less condensation.

However, only about 10 per cent of the total heat loss from the house is through the windows, so there is really no point in putting expensive double-glazed windows in un-insulated walls. Similarly, it's only worth investing in the best triple glazed windows if you have super-insulated the property first.

Glazing

Standard windows will have air in the gaps between the panes of glass. Higher performing ones tend to have argon or other gases between. They will also have a low-E (low emissivity) coating. This allows the heat from the sun into a room, but reduces the amount that escapes again.

Frames

UPVC are a low maintenance option. However, the Centre for Alternative Technology recommend that they should be avoided as their production is energy intensive, and they are polluting at manufacture and disposal.

Alternatives include wood (which needs more maintenance), aluminium and composites which have wood on the inside and aluminium on the outside.

New double glazing is required to have trickle ventilation in the frame (even if the ones you are replacing do not). This is because modern windows are more air tight than older ones.

Efficiency

Some manufacturers label their windows with the standard A-E measures of energy efficiency
