Secondary Glazing for Holiday Let Owners in Scotland — A Practical Guide
If you own a holiday let in Royal Deeside, Aberdeenshire, or along the Moray Coast, you’ll know the challenge. Your property is beautiful — a stone cottage, a traditional Scottish house, a characterful coastal retreat. But Scotland’s winters are unforgiving, and older windows that look wonderful in photographs can leave guests shivering, wiping condensation off the glass, and reaching for their laptops to leave a review you’d rather not read.
The good news is that there’s a straightforward, affordable solution that doesn’t require planning permission, doesn’t damage your property, and can be fitted in a single day with no disruption to bookings. Secondary glazing from InGlaze could be one of the best investments you make in your holiday let this year.
The Real Cost of Draughty Windows in a Holiday Let
Holiday let owners in Scotland face a unique set of pressures that ordinary homeowners don’t. Your property has to perform — not just for you, but for every guest who walks through the door, in every season, in every weather condition.
Draughty, cold, or condensation-prone windows create problems on multiple fronts:
Guest comfort and reviews Cold rooms are one of the most commonly cited complaints in holiday let reviews. A guest who spent their first night in Aberdeenshire huddled under every blanket they could find is not going to give you five stars — no matter how beautiful the location or how well-equipped the kitchen. In an increasingly competitive market, guest comfort directly affects your occupancy rate and your income.
Energy bills Heating a stone cottage or traditional Scottish property with single-glazed windows is expensive. Heat pours out through the glass, your boiler works overtime, and your energy bills reflect it. For a property that needs to be warm and welcoming for guests year-round, this is a significant ongoing cost.
Condensation and damp Single-glazed windows in older properties are condensation magnets, particularly in Scotland’s climate. Left unaddressed, condensation leads to mould, damp, and damage to window frames, sills, and surrounding walls — all of which mean maintenance costs and potential complaints from guests.
The listing building problem Many of Scotland’s most desirable holiday let properties — the stone cottages on Royal Deeside, the traditional houses along the Moray Coast, the historic properties throughout Aberdeenshire — are listed buildings or sit within conservation areas. Double glazing is simply not an option. Secondary glazing is.
Why Secondary Glazing Is Perfect for Holiday Lets
Secondary glazing involves fitting a clear panel on the inside of your existing window, creating an insulating air gap that dramatically reduces heat loss, cuts condensation, and quietens outside noise. Because it fits inside the existing frame, it’s invisible from the outside and doesn’t affect the character or appearance of your property.
For holiday let owners specifically, secondary glazing ticks every box:
No planning permission required In most cases secondary glazing doesn’t require planning permission — even in listed buildings and conservation areas. That means no lengthy approval process and no uncertainty. You can have it fitted and start benefiting immediately.
No damage to your property InGlaze secondary glazing attaches using our patent-pending adaptive seal — no drilling, no permanent fixings, no damage to original window frames or surrounds. Your property is left completely intact.
Fitted in a day A typical holiday let job — one or two rooms — can be fitted in a single day. No need to block out bookings for days or weeks. We work around your calendar.
Fully reversible If you ever want to remove it — for any reason — InGlaze comes off without leaving any trace. For listed buildings this is an important consideration; for holiday let owners it means complete flexibility.
Immediately noticeable results Guests notice the difference straight away. Warmer rooms, less condensation, quieter nights. The kind of thing that turns a four-star review into a five-star one.
What InGlaze Independently Tested Results Mean for Your Holiday Let
InGlaze secondary glazing was tested at the University of Salford Energy House Labs — the UK’s leading facility for real-world building performance research. The independently verified results:
- 50% reduction in heat loss when fitted as a whole-window solution
- 41% reduction in heat loss when fitted to individual sashes while maintaining window operation
- 25% reduction in external noise
In practical terms for a holiday let owner, a 50% reduction in window heat loss means:
- Lower energy bills — your heating system doesn’t have to work as hard to keep rooms warm
- Warmer rooms — guests are comfortable from the moment they arrive
- Less condensation — fewer complaints, less maintenance, less damp risk
- Quieter property — particularly valuable for properties near roads, farms, or coastal areas
InGlaze for Scottish Holiday Lets — Two Products for Different Needs
Whole-Pane Secondary Glazing Our full-frame solution is ideal for larger windows and rooms where maximum thermal performance is the priority.

Attaches using our patent-pending adaptive seal with no drilling or permanent fixings.
Ideal for: Living rooms, main bedrooms, and any room where guest comfort is paramount.
Push-In Panes A simpler, more affordable solution for smaller individual panes — particularly Georgian sash windows. The acrylic panel slots directly into the existing frame with no fixings required. Can be ordered online and fitted without a site visit.
Ideal for: Bedrooms, smaller rooms, and properties where a cost-effective solution is needed for individual panes.

InGlaze is based in Aberdeen, which means we understand the local building stock — the granite cottages of Royal Deeside, the traditional stone properties throughout Aberdeenshire, the coastal houses along the Moray Firth — better than any supplier based elsewhere in Scotland.
We know the window frames you’re dealing with. We know the climate your guests are arriving into. And we know that a property that’s warm, dry, and quiet is a property that gets booked again.
Whether your holiday let is a single stone cottage near Ballater, a traditional house in Speyside, or a coastal property near Findhorn or Cullen — we can help.
