Slim Cavity Units for Northampton properties
Ask three firms about Slim Cavity Units in Northampton and you will get three different answers. Given the ironstone cottages, boot-and-shoe terraces and new town expansion housing that dominates locally, standard sizes are the exception not the rule. dry inland conditions with limited coastal influence sets the pace of decay, and seasonal shrinkage and glazing bead loosening on older painted units is how it shows up first. What you are paying for is narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Give us the basics and you will have a written figure, not a range that moves later.
Worth knowing locally: ironstone reveals absorb water and hold it against frames in wet spells.
