Standards at Bonneville Homes

Each modular home manufacturer has its own construction standards, methods and features, some of which barely meet code requirements. Bonneville Homes will go the extra mile to offer “high quality construction features”, as included in their standard home products.

Listed below are a few of these upgraded features along with their related benefits.

	Open joist 2000 floor system

	The Bonneville Homes floor system integrates engineered open web joists instead of conventional 2” x 10”. Manufactured entirely of kiln-dried solid lumber and waterproof glue, open joist performs better under pressure, temperature and moisture variations, therefore eliminating any creaking. The open-web triangulation makes the installation of ventilation conduits, electrical wiring and plumbing easier, without drilling holes or weakening the structure. The 2” horizontal top core offers a much wider bonding surface and wider support for the plywood sub-floor, which is glued and screwed at 6” on center.

	Highly superior exterior wall systems


	Bonneville Homes’ exterior wall system provides a total insulation factor of R30. The industry standard is R20. Bonneville Homes achieves this 20 to 30% superior insulation factor by using the following advanced materials and methods :

Exterior wall composition from inside to outside:

½”Gypsum board drywall: screwed@ 12” o/c

1” x 3” Horizontal interior strapping @ 16” o/c:
This strapping provides a wider and a more even screwing surface for fastening the drywall. It also creates a 5/8” air space between the drywall and the aluminium vapour barrier. This air space contributes to the total insulation factor of the wall system and allows moisture and humidity to evacuate naturally without being absorbed by the insulation.

Aluminium vapour barrier:
The aluminium vapour barrier offers valuable properties such as reflecting the heat back to the inner face of the wall and increasing the insulation value by 2.6 “R”.

2” x 6” Kiln-dried studs:
Bonneville Homes chooses to use kiln-dried lumber since it is straighter, stronger and carry a lower humidity content.

Cellulose fibre blown-in insulation:
(see specifications below)

Wood fiber sheating:
½ fiberwood high performance sheating.

Tyvek air guard:
Tyvek will minimize air infiltrations, prevent water infiltrations and allows vapour to evacuate the wall system. These features highly contribute to the durability of the wall structure.

Exterior strapping:
1” x 3” exterior strapping installed diagonally at 16” o/c will accept horizontal or vertical siding and will add to the lateral strength of the structure. The 5/8” air space provided between the siding and the air guard allows humidity and water to evacuate the wall system without resistance. The direct result is a longer lasting structure and siding.

	High performance energy efficient features:

	Energy efficient features contribute to prevent air, water or insect infiltrations.

Cellulose fibre blown-in insulation

Cellulose insulation is derived from recycled wood fibre or cellulose fibre, a non-polluting and non-irritant natural material proven free of gas emission.

Cellulose fibre is one of the very few leading materials available to the construction industry composed exclusively of environmentally safe products.

This type of insulation is cited as a reference by Environment Canada in its guidelines for its “Environment Choice Program”.

	Thermal performance per inch of applied material:

	Cellulose fibre provides the highest thermal resistance per unit of thickness of all conventional insulating fibres on the market today. It boasts an “R” value of 3.7/in at a density of 1.6 lbs/cu. ft. in open areas. Cellulose fibre, injected in walls at a density of 3.3 lbs/cu. ft. will reduce by 68% any possible air infiltration.

Fire resistance:

Over the years cellulose fibre has been used extensively in many large construction projects not only as an insulation and acoustical material, but also as an excellent fire resistant agent. It meets the CAN/ULC-S703 standards and has demonstrated its exceptional flame resisting properties in laboratory tests.

Cellulose fibre properties will increase:

The soundproof factor by 400%
The fire retardant capabilities by 200%
The insulation “R” value by 20%

Bonneville Homes reserves the right to change its construction norms or methods, the quantity and/or quality of the materials used, without notice.
