Conservatory LVT Flooring
A conservatory is the most demanding temperature environment in a British house. The same room can sit at 5C on a January morning and 35C on a July afternoon and the floor has to absorb every degree of that swing without cupping, gapping, peaking or pulling away from the perimeter. Luxury vinyl flooring in a fully glued-down format is the only LVT install we will ever specify in a conservatory – and it is one of the very few flooring products that genuinely belongs in the room at all. Engineered wood will move, laminate will telegraph every joint, real tile is cold and brittle on a typical timber subfloor. Glue-down LVT, properly acclimatised, will sit flat for the lifetime of the conservatory.

Why Conservatories Break Most Floors
The defining problem in a conservatory is thermal cycling. A south-facing glass room with a polycarbonate or full-glass roof can move from 5C overnight to 35C+ at midday and back again every day in summer. Wood-based products – solid wood, engineered wood, laminate – all expand and contract with that cycle and are not designed to live with it long term. The result is cupping, peaking, gapping and joints that creak. Real tile copes thermally but is unforgiving on the slab/timber subfloor combination most conservatories sit on and is genuinely cold underfoot for nine months of the year. LVT – and specifically glue-down LVT – is dimensionally stable across the temperature range a conservatory throws at it, warm underfoot and the only mainstream finish that will sit completely flat in this environment for 15+ years.
Glue Down Only – Why Click LVT Is Wrong for Conservatories
This is the single most important spec decision in the room. Click LVT is a floating system that needs an expansion gap around the perimeter of the room to absorb thermal movement. In a normal lounge that gap is well within the 8mm a click joint can handle. In a conservatory the same plank can move two or three times as much and the click joint will eventually peak in the middle of the floor or pull apart at the seams. Glue down LVT has no expansion gap and no floating raft – every plank is bonded continuously to the subfloor with a pressure-sensitive adhesive that holds it stable through the full thermal range. Acclimatisation in the actual room (not the garage, not the hallway) for 48 hours minimum before fitting is non-negotiable. Loose lay is also unsuitable for a conservatory.
Wear Layer – 0.55mm or 0.7mm
For a conservatory we recommend either 0.55mm for premium domestic use or 0.7mm if the conservatory is the main route to the garden, the dog’s exit door, or in regular use as a children’s playroom. The room sees a lot of grit walked in from outside and you do not want to be sanding scratches out of a 0.3mm wear layer in five years.

Key Takeaways
- A conservatory is the most demanding temperature environment in the house, swinging from about 5C overnight to 35C or more at midday and glue-down LVT is the only flooring that stays flat through it; engineered wood, laminate and click LVT all move and tile is cold and brittle on a timber subfloor.
- Glue-down only, never click: a floating floor’s expansion gap and click joints cannot absorb the thermal movement and will eventually peak or gap. Acclimatise the boxes in the actual conservatory for at least 48 hours before fitting.
- Choose 0.55mm for premium domestic use and 0.7mm if the conservatory is the main route to the garden or a playroom; underfloor heating is ideal, but the 27C surface-temperature cap matters most here because the floor is already sun-warmed.

Underfloor Heating in a Conservatory
UFH is the right answer in a conservatory because it warms the slab evenly without the convection problems of a radiator under cold glass. All the glue-down ranges we stock are compatible with both wet and electric UFH up to a maximum surface temperature of 27C – the 27C cap matters a lot in a conservatory because the floor will already be sun-warmed in summer and the UFH should never push it past that limit. Commission the UFH properly through a full heat-up/cool-down cycle before the floor is laid, then bring the temperature back up gradually after the install.
Acclimatisation and Subfloor Notes
Acclimatise the boxes in the actual conservatory for at least 48 hours with the room held at normal living temperature, before the fitter cuts a plank. The subfloor must be flat, clean, dry and primed – most conservatory subfloors are either chipboard or screed and both need a flatness check before any adhesive goes down. If the conservatory has settled at all (most do in the first few years), use a self-levelling compound rather than trying to fight the slope with thicker glue. Run a continuous silicone bead at the perimeter where the LVT meets the dwarf wall.
Continuous-Floor Story – Conservatory, Lounge, Dining Room
The conservatory is almost always seen from the adjoining lounge or dining room and the most expensive-looking specification is to run the same plank from one room to the next without a threshold strip. Pick the wear layer for the conservatory (the harder room) and run it through into the rest of the ground floor.

Frequently Asked Questions
Will my LVT floor fade in the conservatory?
Quality LVT from Amtico, Karndean and the other ranges we stock is highly UV-stable and colour-fast, so it resists fading far better than many alternatives even under the intense sunlight a glass roof lets in. It is one of the reasons LVT is our go-to conservatory floor, though as with any floor, blinds or solar-control glass help protect furnishings in the room too.
Can LVT flooring warp in a conservatory's heat?
Not when it is specified and fitted correctly. Glue-down LVT is dimensionally stable across the temperature range a conservatory throws at it and bonding every plank to the subfloor stops it moving. The keys are choosing glue-down rather than click, acclimatising the boxes in the actual room for at least 48 hours and keeping any underfloor heating below 27C.
Why can't I use click LVT in a conservatory?
Click LVT is a floating floor that relies on a perimeter expansion gap to absorb movement. In a conservatory the planks can move two or three times as much as in a normal room, more than the click joint can handle, so a click floor will eventually peak in the middle or pull apart at the seams. Glue-down has no gap or floating raft and stays stable through the full thermal range.
What wear layer should conservatory flooring have?
We recommend 0.55mm for premium domestic use and 0.7mm if the conservatory is the main route to the garden, the dog's exit door or a children's playroom. The room sees a lot of grit walked in from outside, so a thicker wear layer than the entry 0.3mm keeps it looking good for longer.
Is LVT a better choice for a conservatory than ceramic tiles?
For most conservatories, yes. LVT is warmer and more comfortable underfoot than ceramic, which is genuinely cold for much of the year, it will not crack on the timber-and-slab subfloors most conservatories sit on and it is dimensionally stable through the temperature swings. It matches tile on waterproofing while being warmer, quieter and easier to fit and repair.
