The essentials of house ventilation

Ventilating a home helps to develop a healthy living environment– learn how and about the different ventilation methods offered to property owners.

What is ventilation?

Ventilation is the exchange of air between the interior and exterior of a dwelling. The main function of ventilation in a house is to remove polluted indoor air and replace it with ‘fresh’ outdoors air.

Why is it required in my house?

The distributing air reduces the danger of risk from hazardous indoor contaminants being produced within the home. This helps to offer a healthy and comfy internal environment for the residents of a house.

The Building Regulations Advisory Committee in England and Wales need ‘that there will be adequate ways for ventilation provided for individuals in the structure.’

In Scotland the Building Standards state that ‘all structures need to be ventilated so that the air quality within the structure is not a hazard to the health of the occupants or the building itself.’

Main types of ventilation

Purge ventilation

Sometimes described as quick ventilation, this is the fast exchange of large amounts of air in between spaces or in between a room and the outdoors, and is typically attained by opening a window or a door.

Advantages:

Assists with elimination of periodic contaminants such as smoke and smells from cooking, or fumes from painting and designing

Stops a house from getting too hot and uncomfortable during warm summer season durations

Extraction ventilation

This is the active extraction of air from rooms through mechanical ways, usually with a fan or a/c unit.

Extraction ventilation is needed in rooms that are routinely exposed to toxins or excess water vapour such as kitchens and bathrooms. Such spaces can utilize permanent or intermittent extraction.

Benefits:

Limits the spread of fumes and pollutants throughout a residence

Background ventilation

This is the passive flow of air into and out of rooms through vents, and is attained by means of ‘a little ventilation opening developed to offer controllable ventilation throughout an entire structure’.

Background ventilators ought to preferably be placed 1.7 m above flooring level to avoid noticeable draughts.

Trickle ventilators are perfect for meeting this requirement. Different devices can be utilized to open and close vents to match the activities of the home’s residents.

Advantages:

Background ventilation through drip ventilators can provide a house with a safe, draught-free and consistent supply of ventilation even when windows are secured a closed position

How to pick roof windows for your house

Fixed or opening roof windows

When selecting roof windows for your home, you’ll have the alternative to have a window that is in aircraft (aligned with the roofing) or out of airplane (not flush with the roofing system).

You’ll also require to decide in between an opening or repaired roofing system window. Some designs can completely open, and others will partially open. If ventilation or roofing system gain access to is a concern, an opening roofing system window may be your choice.

There are many different options to select from between fixed and opening roofing windows, consisting of options with security functions like partial opening locks. If you’re uncertain on whether or not to select repaired or opening roofing system windows contact a professional business for an assessment.

Frame products

Just like other kinds of window, roof windows are readily available in a large range of frame materials consisting of uPVC, wood, aluminium and steel.

Particular homes lean towards particular materials more than others, and in some circumstances planning approval for a particular building might just enable a certain material or type of roofing window to be installed.

Metals like steel or aluminium are one choice for a modern-day home, big airy barn discussions, or duration homes. Wood and wood have constantly been a popular choice aesthetically, but upkeep can be tricky when you have to get onto the roofing to get it done.

A great compromise is a timber-aluminium composite which appears like wood but is much lower maintenance. uPVC is naturally extremely long lasting and long-term.

Glazing options

As with other kinds of windows there are several glazing options readily available for roofing system windows. Discovering the right option for your house will depend on numerous elements, however we’ve highlighted some key things to think about when making your choice.

Energy effectiveness

Producers will constantly provide you double glazed roofing system windows as they carry out at an industry accepted level offering light and energy performance

Energy efficient double glazing utilizes 2 panes of glass, sometimes with a gas injected into the space between the two panes, and a Low-E finish which helps to invite the sunshine in, while likewise trapping heat inside the house.

Triple glazing is something you might think about if you wished to invest more cash because it offers that bit more convenience than double glazing, and may simply provide your home the edge if you’re wanting to display your energy efficiency rankings to potential purchasers. Triple glazing differs from double glazing because it uses three panes of glass instead of 2.

Thermal efficiency.

Roof windows are frequently used on the top of the house as they are prone to getting a great deal of direct sunlight, so might potentially make a loft living location uneasy.

Solar control glass is an option which takes the heat from the sun and shows it away throughout summer, to keep the home cooler and make it more comfy.

Personal privacy

Tinted glass will increase privacy and reduces glare, but it can also decrease the amount of light able to come into the house.

Upkeep

Self-cleaning glass can be an attractive option for homes that don’t have easy access to their roof windows. This type of glass reacts to the light shining on it, breaking down particles and dirt to make it much easier to be washed away by the rain.

Security

Laminated safety glass as an alternative for the inner pane of the glass sealed system ensures that pieces are held together if the glass were to break. This alternative is always suggested for bed rooms and children’s rooms.

Some additional notes on glazing

It is important to remember that some roof windows might combine several of these choices. One roofing window might be tinted, strengthened and self-cleaning, so you will not constantly have to pick between features.

It is likewise a great idea to keep in mind that roof windows are rated under the BFRC energy ranking scheme. This plan rates the entire window on its energy effectiveness from A to G with A being the most energy effective and G being the least.

U-Values are also essential and grade windows on just how much heat they blurt, so the lower the U-value, the much better.

Extra devices

If you select a roofing system window that opens there are a number of accessories to consider including locking systems for child security and manual and remote control opening options.

Remote control alternatives might be a factor to consider for windows that are out of reach, or that aren’t easy to reach.

Low-E (Low Emissivity) Glass and Thermal Efficiency

What is Low-e glass?

Low emissivity glass is glass that has an undetectable microscopic covering applied to it in order to enhance its thermal performance.

How does Low-e glass improve thermal efficiency?

Low emissivity glass is a vital part of many energy efficient windows and doors. It has a surface finishing that runs as follows:

It enables short wavelength heat from the sun to enter your home through the glazing.

This solar energy works with your domestic heating unit to heat up your space, which then emits long wavelength heat radiation.

A big percentage of that long wave heat would vanish back out through windows made of regular glass. However, the Low-e covering reflects that heat back into your space so the heating unit does not need to work as tough to preserve a comfortable room temperature level.

Will Low-e glass meet the Building Regulations?

Much better than simply fulfilling the Building Regulations, Low-e glass will allow you to both accomplish and exceed the new targets for doors and windows.

What other characteristics should I know?

Whilst there are significant advantages to picking thermally efficient Low-e glass for your house, there can be some negative effects under particular conditions.

Tint

Recent developments in developing neutral Low-e coatings reduce the phenomenon of light coloured materials (such as net curtains) appearing slightly darker when viewed through the glass.

Haze

This phenomenon may occur sometimes of the day when the sun is at a specific angle or under some lighting conditions. It can likewise be influenced by the type of Low-e covering used.

External condensation

Thermally effective windows are so proficient at keeping the heat in that the outer pane can get cold, as it is no longer being warmed by lost heat.

Under some weather and at specific times of the year, this can result in the development of condensation on the outside surface of the glass. This is a positive indicator of a thermally efficient window.

Shade

Depending on coating type, glass substrate and glass density, some minor colour or shade distinctions may be obvious on Low-e glass.

This may be more apparent when one double or triple glazed window unit is changed in a house, as the Low-e finishing will likely be slightly different (i.e. from a different batch) from those on the other window systems.

Overheating

Specific Low-e glass is good at solar heat gain, harvesting free heat from the sun, helping to lower heating demands. In some circumstances, this can cause overheating leading to an uncomfortable environment.

Are the January Sales the Best Time to buy Double Glazing?

With January sales starting ever earlier each year and time minimal deals like 50% off, BOGOF (buy one get one free) or pay for fronts get the back ones free, is January the very best time to purchase double glazing?

Not always.

Think of it, everyone is dealing with the exact same cold wintry conditions so it is just natural that we think about the cost of heating (as the hum of the heating system as it burns cash as radiators pump away) and the quantity we could conserve, if we bought new, energy effective, windows.

Supply and need suggests that if need is high, so too are the costs. There may be offers on throughout the January sales, however business are not normally short of organisation whilst it is cold, what’s more, those business who likewise run in the social housing or council repair works find themselves actually hectic, under pressure to produce and set up windows before the April financing spending plan is lost.

Clearly there’s no damage starting the process now, getting quotes and going to display rooms, however you might discover that business are less busy (and therefore more happy to offer a discount rate) later on in the year.

Do not forget to ask what discounts are readily available.

Sometimes, you’ll find business are genuinely prepared to use discount rates if your home is used in marketing, images or showing others in your location etc, but do ask first because sales individuals have been known to accept some random discount just because you suggested something (I’ve heard of a salesman offering a Police discount when one didn’t exist, but only if the order is put there and after that).

On the whole the market has moved away from the “sign on the dotted line”, but some still pressurise customers into booking the deal there and then. Most decent business are pleased to validate their finest costs in composing, that way you’ll see exactly the items you are considering. You’ll also have the opportunity to examine online reviews on our website, the accreditations the business is claiming to have and the date the company was formed by using the “business home” tab.

Glazing and Sound Elimination in Your Home

Changing or updating your windows can enhance noise decrease in the house.

What is sound?

Sound is undesirable sound. In the home, this is any sound that sidetracks or disrupts the residents.

This could be anything from nearby traffic or low flying airplane to noises coming from neighbouring properties such as music and loud conversation.

How it travels

Sound journeys through the air (and solids and liquids) like the ripples seen on the surface of a pond when you throw a stone into it. Similar to these ripples, the waves decrease in strength as they move far from the source.

Sound intensity is determined in decibels (dB). A low dB worth shows a soft sound and a high dB value a loud noise.

How it affects us

The perception of noise will differ from person to person relying on the source of the sound and the person’s tolerance/acceptance of an offered kind of noise

For example, an individual living next to a hectic road for a number of years may have become familiar with it, whereas someone relocating from a quiet location to the very same busy roadway may discover the noise an annoyance.

How glazing can help in reducing sound.

One of the many potential benefits of replacing windows or installing secondary glazing in your house is that in doing so you can often also improve your property’s sound insulation.

The correct setup of good quality, well-made windows or secondary glazing systems can result in a noticeable decrease in sound levels.

Type of glass

The type of glass used within your replacement window might have a result on the level of sound reduction. Glass is readily available in a variety of densities and normally thicker glasses reduce more sound.

Domestic windows generally use 4mm-6mm thick glass Some window panes are made up of two or more pieces of glass that have actually been bonded together; these are called laminates. Expert, acoustic laminated glass is available from lots of glass producers.

Density of glass.

Different thicknesses of glass work at lowering sound at various frequencies. As a result, a sealed double or triple glazed system with glass panes of various thicknesses (i.e. both 4mm and 6mm) will work at lowering noise across a wider variety of frequencies than if both panes of glass were the same thickness.

Triple glazing

In addition to decreased thermal losses, triple glazed units can provide a decrease in noise. By increasing the combined thickness of the glass within the unit, the mass is increased. A reduction in sound transmission will result from this additional mass.

Air gap

The size of the air gap between the panes of glass in either a double or triple glazed window or a secondary glazing system makes a substantial difference to the level of noise insulation. Generally a large air space will improve sound insulation.

Secondary glazing

Secondary glazing is when another window or glazed screen is placed within the window reveal of an existing window.

The additional glass pane and air space now present in the window system aid to enhance its noise insulation properties. In some cases, sound reduction can be even more enhanced by lining the window reveal with sound insulation product.

The effect of ventilation and air spaces on noise reduction

To be effective in decreasing noise brand-new windows and secondary glazing systems need to be fitted and sealed correctly. Any air gaps around your window will seriously impact its noise reduction homes.

It is also crucial that any opening window can be safely closed with a good quality seal. If the window does not close correctly sound will be able to penetrate the home.

Bear in mind that many windows are developed to offer your home with a way of ventilation. Background ventilation through drip ventilators can, if left outdoors position, offer a passage for noise to travel.

Similarly, an open window, maybe in the night lock position, will not help sound reduction.

Glazing may just become part of the solution

Replacing or updating the glazed components of a home may not singlehandedly solve the problem of extreme noise levels.

This is since noise getting in the home by means of roofing systems, walls and floors will not be decreased as a result of changes to glazing. Depending upon the source of the noise and type of home, replacing or upgrading the glazing may just belong to the service.

Can You Double Glaze Traditional Timber Sash Windows?

Although double glazing existed earlier, UK households didn’t start to install double glazed windows until the 1970s and 1980s.

This means that houses with original timber windows from the Georgian, Victorian and Edwardian periods would have been single glazed.

Double glazing involves having a gap between two panes of glass, which is normally filled with either argon or krypton gas. Air is a poor heat conductor, meaning that heat loss is reduced so your home retains the warmth.

The internal glass pane in a standard double glazed units is manufactured using a soft coat low emission glass, which reflects heat back into the building. This helps further improve the thermal efficiency of your home.

Providing planning permission allows it, there is no reason why any replacement timber windows cannot be double glazed. In fact, double glazing often comes as standard today.

This means that you can benefit from improved thermal efficiency as a result of double glazing, while also preserving the traditional look and feel of your period property by installing replacement, double glazed traditional timber sash windows.

All replacement timber windows are bespoke and designed to enhance both the look and value of your property, by being as energy efficient as possible while also being in keeping with the architectural style of your home.
