i am planning on installin a double glazed window into
the gable end of my house i have the lintel and was after
a few pointers as the best place to start installing them
or i guess you could say i was after help on this whole thiing
Is the gable wall double skinned brickwork, solid stone, brick faced timber
construction or (?) ? What
load rating does the lintel have for its length ? Does the gable wall have a
chimney breast or other
attachments on or against it ? Does the opening also require a sill ? What
type and weight or load will
be above the opening ? Will the roof structure need temporary struts before you
start to cut a slapping
in the walls ? Will the wall need corbelling butts if the slapping removes to
much of the lower structure
below the slapping ? Do you need planning permission before you start to
overlook other peoples
properties and violate their privacy ? Will the new window come up to new
ventilation and thermal
retention requirements ?
Need input !!!

And.. Have you submitted a Building Regulations application? How far
from the boundary is the gable? If it's less than 1m to a
neighbouring property, then the area of the window (between reveals)

A cavity wall will need two angle iron lintels, one for the outside skin, and
one for the inside skin, to
be able to keep the cavity qualities in the whole wall.
There is no flat roof from any extensions built against the gable ?
The window may already have a sill, but an additional moisture barrier may be
needed under the window to
prevent any ingress from wind blown rain and drips. Best check with you local
Depending on how much of the wall you're removing, then you may need internal
support to prevent the wall
from bending or sliping when the new slapping is done. Because you're removing
part of the wall, you may
be taking a lot of the weight out which is actually holding the wall in place,
so this needs a structural
survey to tell if the wall will need extra support to be able to take the wind
and movement that elements
throw at the house.
It depends on the weights you're dealing with in this job, so it's best to ask
the help of a structural
engineer on this one.
Depending on how much weight you're removing the wall, then it may be necessary
