All-time Insulation for Homes

To say anything is the best insulation for homes is clearly a subjective statement and I've no doubt in that location are people out there who may disagree with my choices.

Still these are my opinions (if you disagree please feel free to annotate or propose your all-time insulation for homes at the bottom of the folio).

For a more in-depth information on each type of insulation delight feel free to follow the links below to each of the individual insulation articles.

The Best Insulation for Homes Heat Loss Diagram for a Typical House

Why practise we demand insulation?

An uninsulated dwelling loses approximately (these are very rough figures and will vary with dissimilar house types and construction methods):

25% of its heat through the roof
33% through the walls
15% through the floors
15% through draughts
20% through the windows.

The vast bulk of that estrus loss (effectually 58%) comes from 2 areas i.e. the roof and walls.

The ironic thing is these are areas which are fairly straight forwards to insulate (unless you accept an quondam business firm with solid walls or your house has a room built into the roof space).

So it'due south not difficult to encounter why calculation insulation to your walls and roof can reduce your heating costs significantly and information technology's pretty affordable and easy to do.

How Does Insulation Work:

It'southward really important to understand how insulation works, if you want to accept any chance of choosing the best insulation type for your situation.

New Build Backdrop and Extensions:

When building a new home or extending your electric current dwelling house the corporeality of insulation volition exist dictated by building command. Yous could always increment on what they advise if you'd similar to attempt to reduce your heat loss even further.

Modern standards are pretty high and you do get to a betoken where it'southward no longer cost effective to just keep adding insulation. Notwithstanding, traditionally builders and insulation companies tend non to utilise Vapour command layers or breather membranes when installing insulation so there is always ways of improving the efficiency of your insulation regardless of the age of your home.

The best Insulation for Homes When Retrofitting or Refurbishing:

As mentioned above the 2 main areas where people retrofit insulation are the loft and the walls, simply you should likewise consider insulating any suspended timber ground floors you have. Just even in these areas in that location are lots of dissimilar wall and roof construction types out there and these all accept unlike requirements when it comes to retrofitting the all-time insulation for homes.

When retrofitting there will be sure insulation types that you lot just can't use, such as solid insulation sheets similar polystyrene sheets or foil backed PIR boards etc. when installing cavity insulation to an existing property, as you can't gain access to the cavity in order to fit them.

And don't forget that when you add together or upgrade insulation you lot'll need to add together a vapour control layer (VCL) on the warm side of the insulation (NOT a vapour bulwark) and a sabbatical membrane on the cold side of the insulation. The VCL restricts the amount of water vapour entering the insulation. Failure to install a VCL would allow h2o vapour to permeate the insulation causing interstitial condensation within the insulation, reduce its effectiveness and could potentially cause rot to timbers.

The breather membrane will help reduce estrus loss from wind wash (where air movement over the insulation draws heat out of information technology), reduce draughts from uncontrolled ventilation and allow any water vapour within the structure or insulation to escape, but more about that later.

Best Insulation For Homes - Generally:

Choosing the Best Insulation Materials -This commodity looks at the different types of insulation available to you and how each performs enabling you to make an informed determination.

Best Insulation For Homes - Types of Insulation:

Traditional Insulation Materials:

Traditional or manmade insulation is what the vast majority of homes volition accept within them. Simply there are, in my opinion, a lot of downsides with this form of insulation. Not charter the Volatile Organic Compounds (VOCs) that they give off, the fact that they do not readily absorb or release water vapour and the fact that they are chemical based, to name a few.

The most common forms of the traditional insulation materials are as follows:

Rigid Foam Insulation – rigid insulation is commonly used in the walls, floors and ceilings. But what are the different types bachelor and which are the best? Read more than here.
Wool Type loft insulation – this is the most common course of loft insulation for cold roofs and is typically Fibreglass or Mineral fibre based. Information technology is typically installed in lofts just is sometimes used as cavity insulation where it can crusade Large bug.
Aluminium foil backed insulation – If your loft aea has "warm roof" insulation (insulation laid betwixt the rafters int he roof rather than the joists, this is probable what you have although I also see Fibreglass wool used.
Multilayer foil insulation – not equally mutual but is used in more specific applications where other forms of insulation may not be suitable.

Foam Spray Insulation - this is taking the U.s.a. by storm, but is information technology any good? Discover out the advantages and disadvantages of this latest insulation option. Read more here...

Natural Insulation Materials:

The natural insulation materials are starting to get more and more popular as we start to realise the benefits of this material for our homes likewise as our families who will be living in them. They recycle natural materials, they easily absorb and release moisture, they don't incorporate whatever nasty chemicals or VOCs and they can be made perform besides as chemical based insulation materials (but this volition normally require a thicker installation).

Wood Fibre Insulation - my personal favourite for a number of reasons. It tin be used as loft insulation, internal or external wall insulation or floor insulation and it'south easy and pleasant to work with.
Sheep's Wool Insulation - for some reason this is ofttimes viewed equally the poor relative when information technology comes to insulation. But y'all'll be shocked when yous see what all this innocent, natural material is capable of...Read more here.

1. The All-time Insulation for Homes with Cavity Walls:

Traditional Cavity Wall Insulation

Traditionally, in a new build cavity wall, there would exist a layer of insulation lath against the inner leaf of the wall and an air void adjacent to the outer leaf of the wall. Merely if there are gaps betwixt the sheets of insulation the thermal efficiency for the wall falls off a cliff.

The principle of this was to have a gap next to the outer leaf in order to avoid whatsoever moisture that may penetrate the outer foliage from being transported across the insulation to the inner foliage which could cause penetrating damp inside the dwelling.

In an existing property with cavity walls you can't obviously remove the outer leaf to install insulation boards and maintain a gap. And so the but options are to pump in insulation or insulate externally or internally. But the latter two commonly aren't done due to the increased costs involved. Filling an existing cavity with insulation can heighten its own issues which are explained in my commodity on cavity wall insulation issues below.

There are of form a few types of cavity make full insulation that are available but I'chiliad not a fan of many of these for reasons I'll go into inside the articles below.

You have a huge selection of materials simply you should utilise a material that is breathable and install a vapour barrier or VCL and an airtightness layer if you want to practise it correct. Have a read through the articles below to see what the advantages and disadvantages of each are and why the majority of these types are installed incorrectly, without vapour barriers, VCLs and airtightness layers.

External Insulation - Where yous physically add insulation to the exterior surface of your master walls. But at that place'south more to it than y'all might retrieve.
Internal Insulation - Equally the name suggests, this type of insulation is added to the inner surface of the master walls of your house. Merely, you guessed it, it's that directly forward, in that location are some things you lot MUST include.

Cold Roof Insulation

Common cold Roof – this blazon is where yous lay the insulation on top of the ceiling of the habitable rooms (or between and on superlative of the joists). When installing or upgrading your loft insulation there are a few very of import steps that are normally missed but if done correctly volition increment the functioning of your insulation and help yous avoid future issues.
Cold roof insulation is the most common blazon within traditional houses while a "warm roof" is more than mutual in chalet style houses where you lot have habitable rooms within the loft area.
