Slimline Secondary Glazing
Narrow secondary frames can reduce the visual prominence of an additional internal window.

Slimline Secondary Glazing — install narrow frames within limited reveal depth, with the installation method, protection and finishing details planned.
Appearance is considered alongside the fixing surface, glazing weight and hardware space. The smallest-looking profile is only useful if it suits the opening and intended operation.
The detail that matters
Can the frame colour complement the existing window?
Discuss the available manufacturer finishes and compare samples with the actual window before ordering.
