Expert guidance on palram canopia mythos greenhouses
The Palram Canopia Mythos is the definitive choice for gardeners who prioritize thermal insulation and plant protection. By utilizing 4mm twin-wall polycarbonate for both the roof and walls, the Mythos makes a "double glazing" effect that retains heat far more effectively than single-wall models. To optimize your growing environment, we recommend browsing our Greenhouse Accessories for automatic vent openers and high-quality Greenhouse Staging to organize your tiers.
Technical glazing comparison: mythos vs. hybrid vs. harmony
Choosing the right polycarbonate depends on whether you value insulation (Mythos) or visibility (Harmony). The table below breaks down the technical differences:
| Model | Roof Glazing | Wall Glazing | Primary Benefit |
|---|---|---|---|
| Mythos | 4mm Twin-Wall | 4mm Twin-Wall | Maximum Insulation - Best for overwintering. |
| Hybrid | 4mm Twin-Wall | Clear (Single-Wall) | Balanced - Overhead shade with clear views. |
| Harmony | Clear (Single-Wall) | Clear (Single-Wall) | Maximum Light - 90% transmission for seedlings. |
Why We Chose This Range
“We stock the Palram Mythos specifically for the early-season propagator. Because the twin-wall polycarbonate acts as an insulator, it holds the overnight heat much better than single-wall versions. This means your Greenhouse Heaters don't have to work nearly as hard to maintain a frost-free environment. While you lose the 'crystal clear' view of the Harmony, you gain a structure that diffuses 100% of harmful UV rays, meaning you’ll rarely need to invest in additional shading kits even in mid-July.”
, Matt, Founder of Greenhouse StoresMatt's installation tip: sealing for stability
The Mythos is lightweight and easy to build, but because twin-wall panels have hollow 'flutes', they can occasionally rattle in high winds. When assembling, ensure the panels are seated deep into the aluminium channels.
Importantly, you must bolt the galvanised steel base to a solid foundation like concrete or paving slabs. Important Note: If you live in a very windy spot, we recommend that you buy a Toughened Glass Greenhouse rather than polycarbonate, as they are significantly more wind resistant due to their sheer weight. However, for a standard garden, a Mythos anchored with expansion bolts is a solid, rot-free performer.”
Frequently Asked Questions
-
What is the main benefit of the Mythos twin-wall glazing?
The primary benefit is thermal insulation. The 4mm twin-wall structure traps air between the layers, acting like double glazing. This keeps the greenhouse warmer in winter and prevents plants from scorching in summer by diffusing direct sunlight.
-
Is the Palram Mythos greenhouse easy to assemble?
Yes, the Mythos uses a "Slide-and-Lock" system. The polycarbonate panels slide into the aluminium frame channels without the need for fiddly glazing clips. Most 6x6 or 6x8 models can be assembled by two people in roughly 4-6 hours.
- Does it come with a base?
Every Palram Mythos greenhouse includes a galvanised steel perimeter base. This ensures the frame stays square and provides a secure point to bolt the structure down to your concrete or paved foundation.
- What sizes does the Palram Mythos come in?
The Mythos runs from 6x4 up to 6x10, with 6x6 and 6x8 in between. The 6x4 suits a small plot or a first greenhouse, and the 6x10 gives a long growing run down one side. Frames come in silver, grey or green to suit your garden.
- How much does a Palram Mythos greenhouse cost?
The 6x4 starts at £344, with larger sizes and the green or grey finishes costing more. Every model is rust-proof aluminium with shatterproof polycarbonate, so there is next to no upkeep once it is up.
