Cavity wall insulation:

Why get cavity wall insulation..?

Cavity wall insulation is an effective way to save energy and money at home. A well insulated house keeps warmth exactly where you need it - indoors.

So, insulating your cavity walls will help you to heat your home more efficiently. Using less energy reduces carbon dioxide emissions (CO2): one of the biggest causes of climate change. You will also save money on your bills too.

Cavity wall insulation can also help to reduce condensation inside the house if it is a problem on external walls.

Cavity wall insulation can also increase your home value and comes in handy for the new info (HIPS-HOME INSULATION PACKS) packs which were brought into effect in early 09’.

Materials we use: Instafibre White Wool This grade comprises granulated glass wool fibres manufactured from silica sand and treated with an inert water repellent during manufacture It is a new generation product developed specifically for use in cavity walls.

How is it installed?
We inject the cavity wall with the material by drilling holes in the external walls. Through the mortar joint. Holes are 22mm in diameter and are “made good” after injection. Cavity wall normally takes 2 hours to install but could take longer depending on the size of the property.

Cavity Wall insulation will last for the life of your property and is covered by a 25year CIGA guranatee.

Loft insulation:

Why get my loft insulated..?

Heat will always flow from a warm area to a cold one. The colder it is outside, the faster heat from your home will escape into the surrounding air.

Insulation makes it much more difficult for heat to pass up through your roof by providing a layer of material which has lots of air pockets in it. These pockets trap heat, cutting what is known as the U value of the loft.

The U value measures how quickly it loses heat so the lower the U value, the less energy you need to keep your home warm. Loft insulation cuts your loft's U value from around 2.3 (for an un-insulated loft) to 0.16 W/m2K, a reduction of around 95%. You may on occasions also see references to an R-value. An R value is a measure of thermal resistance and is the inverse of a U value so the higher the R value the better. The NIA recommend lofts should be insulated to an R value of between 6.1 and 7 Km2/W. The R value is usually displayed on the packaging of insulation. R values can be added together to reach the total required.

25 % of your homes heat is lost through your roof…that’s 25% of money you spend to keep your home warm!

Loft insulation also helps to keep your property’s temperature consistent and prevent condensation keeping you warm in the winter and cool in the summer!

Loft insulation is effective for almost 40 years and that’s value for money!

If everyone in the UK installed 270mm loft insulation, we could save more than £700 million and nearly four million tonnes of CO2 every year. That's enough to fill Wembley Stadium nearly 500 times.

Wall Tie Replacement:

Why a Cavity Wall?

Cavity walls incorporating metal ties have been in use since the 19th century. They are common in dwellings built in the early part of the 20th century and large numbers of such houses were built during the building boom of the 1930's. Since 1950 the cavity wall has become the standard form of construction for housing and buildings of a similar scale. The purpose of cavity construction is to improve the weather resistance of the traditional nine inch masonry wall by splitting it into two leaves of 4? inch brick, linked with metal ties. The floor- and roof-loads are carried on the inner leaf, the outer leaf is simply a weatherproof skin while the ties contribute to the stability by improving what engineers refer to as the 'slenderness ratio'.

How do you recognise a cavity wall?

By looking at the pattern or "bond" of the bricks. If all the bricks are laid with the long edges ('stretchers') facing you, the wall is a cavity wall. If alternate bricks are laid with the short edge ('header') facing you, the wall is probably a solid wall; 'headers' are used in this way to increase the strength and stability of the masonry.

Of course, if the wall is rendered or plastered and the bond cannot be seen then the easiest way to test its construction is to drill a small hole through the outer face to a depth of some 5? inches. If no cavity is found in this way the wall is probably solid. This will be confirmed by checking the wall thickness at door openings or window reveals. A cavity wall measures 10? or 11 inches (depending on the cavity width) a solid wall 9 or 13? inches (depending on the number of bricks in depth.

How It Works

Structurally, the cavity wall is a load sharing system with ties laid out in a uniform spacing pattern: a diamond formation with ties at 900mm centres in courses set 450mm apart. At door and window openings the spacing is reduced to 300mm vertically.

This spacing is most important where cavity walls are most vulnerable: in small areas of brickwork between openings and in large un-reinforced areas in exposed positions such as gables, where, in the absence of the lateral restraints nowadays required in housing, the walling derives no restraint from the junction with the roof. The chief danger in these positions is from wind suction which, on the leeward side of a building, can exert considerable force which the brickwork, strong in compression but weak in tension, cannot withstand without effective ties at the correct spacing.

The Wall Ties

Although ties in bronze, cast iron and slate are sometimes seen, the commonest material for tie manufacture is mild steel and the commonest manufactured forms are the fishtail or vertical twist ties (either galvanised or bitumen coated) and the galvanised butterfly wire tie.

All mild-steel ties are susceptible to corrosion over time, as the Building Research Establishment has pointed out in its publications, particularly Digests 329 and 401. Because the service life of the masonry is much longer than that of the mild steel it follows that at some point in its life the wall may need replacement of the ties.
