Secondary Glazing in Slaithwaite, Huddersfield
Most of the Slaithwaite housing stock is canal-side mill village stone housing with stone-mullioned casements. It's a designated conservation area, so any window upgrade has to leave the frontage unchanged from the pavement. A room-side secondary system is the standard answer.

What Slaithwaite homes typically need
Canal and rail village deep in the Colne valley.
Typical window: stone-mullioned casements.
Most common brief: damp stone walls, cold reveals and trans-Pennine rail noise.
Slaithwaite is a conservation area, so any frontage-visible change would need consent — our room-side install typically clears without formal consent because nothing is visible from the pavement.
Common questions
Do you match the frame colour to my existing joinery?
Yes — powder-coated aluminium is available in white, black, grey, satin anodised or any of 200+ RAL colours, colour-matched on request.
What if I've got Article 4 restrictions?
Article 4 applies to changes visible from the highway — a room-side install isn't visible from outside so it's usually unaffected.
Will the frame be visible from outside?
No — the entire system sits room-side of the original window. From the pavement your frontage looks unchanged.
Will the install harm the original sashes?
No — the secondary system fits into the reveal, not into the sash box. The original window operates exactly as before.
Is listed-building consent needed?
In many cases no, because no historic fabric is altered. Where it is needed we supply drawings and specifications with your quote at no cost.
