ICE GUARD [2 records]

Record 1 2011-05-20

English

Subject field(s)
  • Roofs (Building Elements)
  • Security Devices
DEF

A guard that prevents snow from sliding off a sloping roof.

CONT

Snow guards are objects used to hold snow on slippery roofs. ... Some snow guards are attached mechanically, while others are adhered to the roof surface. ... Multiple rows of snow guards spaced well apart up the roof are better at holding snow in place (i.e., avoiding the dynamic loads created by sliding snow) than one row of last-resort snow guards placed near the eaves.

CONT

They put up this huge ladder that went up past the window to Papa's office, and up past aunt Olga's bedroom. Then past the loft window and right up to the guttering where the repair man tied it to the iron snow-catcher that stretched along the whole edge of the sharply sloping roof.

OBS

ice dam: This term was submitted to our language information service and appeared in the following sentence: "An ice dam is being installed at the back of the building to stop any ice and snow from falling on the deck." However, since we could not validate this use of the term in any other source, we do not recommend its usage. An "ice dam" is normally (and correctly) used to designate a ridge of ice that forms at the edge of an inadequately insulated and ventilated roof and prevents melting snow (water) from draining off the roof, causing ice damming (in French "digue de glace").

Domaine(s)
  • Toitures (Éléments du bâtiment)
  • Dispositifs de sécurité
DEF

Dans les régions à fort enneigement, sorte de petite barrière à lattes ou à lames établie au-dessus des égouts des toits, et à plusieurs niveaux sur les grands pans de toiture, afin d'empêcher la neige accumulée de glisser et de tomber des toits sous forme de plaques massives et dangereuses.

CONT

[Les] arrêts de neige [...] doivent être adaptés au profil des tuiles et répartis de façon uniforme sur toute la surface de la couverture. [Ces dispositifs] peuvent être [...] associés aux éléments de couverture ou à leur support, [p. ex.] crochets arrêts de neige [fixés par] accrochage simple sur la tuile [ou par] clouage sur liteau, [ou être] indépendants (type barres à neige), [fixés] sur la charpente et non sur le support de la couverture.

CONT

L'installation d'un système d'arrêt-glace va à l'encontre du but premier recherché par les techniques d'isolation et de ventilation des toitures : c'est-à-dire empêcher la formation, à la base du toit, d'une digue de glace qui provoquerait au moindre dégel des infiltrations d'eau, une usure prématurée, etc. On provoquerait artificiellement et avec une quasi certitude des risques de dégâts.

OBS

Les arrêts de neige (ou garde-neige) peuvent prendre diverses formes : crochets garde-neige (appelés aussi «crochets arrêt de neige», en anglais : «snow hooks») ou barres à neige (en anglais : «snow fences»).

Record 2 2008-04-25

English

Subject field(s)
  • Exterior Covering Materials
  • Roofs (Building Elements)
DEF

An adhered waterproof membrane installed under shingled roofing, around skylights or along eaves to avoid leaks caused by ice dams and icicles.

CONT

When snow and ice melt, trapped water can infiltrate to damage the roof deck and interior. Ice Guard [trademark] is installed under shingled roofing to prevent water damage from ice dams. ... Applied under the shingles, Ice Guard forms a long-lasting waterproof barrier, unlike normal shingle underlayment. Ice Guard is warranted to protect against water leakage, where it has been applied, for the warranted life of the new shingled roof.

OBS

Icicles and ice dams. An adhered waterproof membrane is needed under steep roofing such as shingles at valleys, around skylights and other large penetrations, and along eaves to avoid leaks when icings back up water in these places.

OBS

An ice dam is a build up of ice and water that works its way under shingles/shakes. When snow/ice from the peak melts (caused by warm spots in the attic or the sun), water slowly runs down the roof. ... Most roofs have a single layer of underlayment (i.e. builder's felt) that protects against moisture penetration and in many northern states an extra waterproofing membrane is required by building codes.

French

Domaine(s)
  • Revêtements extérieurs
  • Toitures (Éléments du bâtiment)
DEF

Membrane d'étanchéité que l'on applique sur la couverture pour empêcher la formation d'amoncellements de glace (appelés digues de glace, en anglais : «ice dams»), lesquels sont responsables d'infiltrations.
