Leaves, snow and ice are the enemies of every roof drainage system. Gutter Stark® puts an end to blocked gutters and in doing so improves protection against moisture penetrating the building. Gutter Stark® leaf guard ensures undisturbed drainage, even in sub-polar conditions. The new gutter protection is a pioneer in terms of performance due to the proven Alu-Rex technology. Gutter Stark® is also persuasive as a pre-filter for rainwater collection. Dirt is removed from the rainwater, making it available for further use.
The new Gutter Stark® leaf guard was developed as a complete set for all the most common gutter sizes and types. It is available in aluminium and in anodised copper-coloured aluminium.
Gutter Stark® remains functional all year round and the gutter cleans itself automatically thanks to its unique perforated structure (Alu-PerfTM), as proven by two independent tests. The system achieves a drainage rate of 63 millimetres per hour and square metre, even with 100 percent coverage. Gutter Stark® doesn't give up during downpours, either: the Roll-BackTM profile ensures that the volume of water is perfectly managed. The overflow stop band (Flex-SealTM) hermetically seals the gutter as well.
Gutter Stark® drainage capacity when the perforation is covered by residue:
| % of the covered opening | Drainage quantity (mm/h/m2) |
| 0 | 755 |
| 20 | 687 |
| 40 | 625 |
| 50 | 537 |
| 60 | 469 |
| 70 | 396 |
| 80 | 321 |
| 90 | 221 |
| 100 | 63 |
These results were measured and certified by two independent laboratories – Intertek and CRM Rainwater Drainage Consultancy.
Gutter Stark® can withstand virtually any weather. An additional sealant has been applied to its aluminium as well. Even ice and snow don't stand a chance and Gutter Stark® can of course remain in the gutter all year round, unlike conventional solutions.
Are you wondering how often you need to clean the gutter? You may need to have the gutter cleaned by a professional if your roof is hard to access. Gutter Stark® puts an end to constant gutter cleaning. The guard system does not sit too deep in the gutter, so leaves, moss and tree needles are blown away by a light wind of just 10 km/h.
Wind speed required to blow debris away from the surface of the Gutter Stark®.:
| Dirt | spread over 30 cm | Wind speed |
| Dry leaves | 20 | minimal |
| Fir needles | 200 | 8 km/h |
| Damp leaves | 200 | 10 km/h |
| Pine needles | 100 | 10 km/h |
These results were measured and certified by two independent laboratories – Intertek and CRM Rainwater Drainage Consultancy.
