Brick cladding refurbishment to exterior BISF house
Brick cladding to exterior BISF house
Some 20 years ago BISF House.com purchased a typical and unloved BISF in Birmingham. Our aim was to completely renovate the house using an approved builder who was familiar with the steel framed structure and unique design that the BISF house had. After a long search, we finally found a skilled builder who had previously renovated several BISF houses to a very high standard and had examples of his work that we could view..
Our intention was to fully clad the entire house in a brick skin using full sized standard bricks which would be tied into the existing structure of the house. We also wanted to extend the living room at the front of the house so that we could enjoy a more spacious living room. During the renovation we overcame many obstacles concerning the existing structure but in general the build went very well and was completed in good time.
The local planning department oversaw every stage of the work and even dictated the colour of the roof steel roofing tiles. As this house was the first in the street to be renovated, the roof tile colour was intended to set the standard for future roof installations in the street, but of course, nobody followed this and the street now displays a variety of different roof colour with grey being my favourite colour.
Our advice, should you choose to undertake any work to your BISF House, is to ensure you employ a qualified builder who has experience in working with BISF Houses.
Time and time again we have seen general builders applying standard building techniques to BISF houses with disastrous results. The steel frame of these properties and the outer cladding and render are very specific to these houses and standard building methods do not always combine well with the structure.
So please, do your homework before undertaking any structural work to your house and be safe rather than sorry.
Hi there, we have just had an offer accepted on a BISF house in Hornchurch and it's currently clad in pebble dashing. We're keen to change that to a brick clad, so I was interested to know if you went for a full brick skin or used brick slips?
Hi Jo, would in general it would be better to fit the EWI after you have had the extension fitted.
This is mainly because the EWI is usually fitted onto starter tracks where the the wall first starts at floor level. The insulation boards sit on top of these lightweight metal tracks to give a little support but also to act as a drip strip and stopping vermin from getting up behind the insulation boards and nesting there.
If you had the EWI installed before the extension work, you may also find that the builders may need to remove some of the new insulation when joining the new roof to your existing building, which will likely add to your costs.
The boards are easily affixed to the steel sheeting using very long fixing screws. Some companies also use a type of adhesive along with the screws for added strength. Other companies choose to remove the upper steel cladding and replace it with timber boarding onto which the insulation is affixed.
As with any extension work though Jo, you must stress to your builders that extreme caution must be used with any cutting equipment they use that creates sparks, and also with any naked flames such as those used for laying roofing felt. The small amount of paper covered cavity wall insulation can be extremely flammable. The cavities are also designed to allow the free flow of air which is pulled in from the bottom of the cavity. This air then travels straight up into the loft space and around the building. Any spark or flame has the potential to ignite the insulation causing a fire which could spread very rapidly through the walls and even into your neighbours property.
I don't want to alarm you or prevent you from going ahead with the build as the vast majority are carried out with no issues whatsoever as long as precautions are taken. You may also want to consider checking with your insurance company prior to starting work, if extra cover is available during construction as many insurers do not cover accidents caused during building works unless you notify them in advance.
It's always better to be fully protected.
