1 The benefits of building your home using a structural timber building system Bryan Woodley - Flight Timber / Scotframe / Val-U-Therm STA Members What s a structural timber building system? Prefabricated whole house timber building system forms the structural envelope of your home. Vast array of systems that deliver high performance building envelopes 1

2 Alternative Timber Building Systems System choices include Timber Frame open and closed panel Structural Insulated Panels (SIPs) Glulam structures Solid Timber - CLT structures Include roofing and flooring elements to form a coherent building structure. More than structural solutions -also provide thermal, acoustic and fire performance Manufactured using advance off site manufacturing techniques The prefabrication continuum Glulam Post & Beam Open Panel Closed Panel SIPS Volumetric Price Considerations Design flexibility Performance Lead time Construction duration 2

6 What are the benefits of using these systems to build your home? Off-site modern method of Construction Improved health and safety -work is carried out under safe, high quality environments. Tight tolerances high dimensional accuracy. Fewer man hours on-site less dependent on site supervision Less waste, cleaner site. Reduced noiseand dust improved site and surrounding environment. 6

7 Right first time quality Systems are precise, consistent and therefore provide reliable and dependable quality. CAD Design systems Manufactured in factory quality controlled conditions Advanced and reliable manufacturing techniques Audited ISO & OHSAS management systems Faster construction process Offer a 30%+ reduction in overall build programmecompared to traditional builds Rapid dry envelope -allows access for follow on trades earlier Service integration and open web joists reduce fit out times. Highly predictable build schedules Benefits - Saves time and money Not delayed by wet and cold weather Less labour and supervision required on site 7

8 Exceptional thermal performance Assured performance exceeds building regulation requirements and assures SAP compliance. U-Values typically range from 0.22 to 0.10 W/m2K Airtightness as low as 0.6 air changes per hour Systems can offer reduced thermal bridging, with thermally modelled Junctions Ideal for building to even Passivhaus performance levels Assured system performance Independently tested and certified performance -It does what it says on the tin! Product Certification providing specifiers with assurance on both performance and regulatory compliance Thermal Fire safety Health & safety Structure Recognised by warranty providers and lenders 8

9 Cost certainty Predictable and reliable build costs due to system certainties Less prone to variable on site costsarising from poor workmanship, weather and time issues Lower lifetime costs thanks to highly energy efficient structures. Lightweight build system reducing expensive foundation costs Design Flexibility Design flexibility afforded by fully engineered construction systems Whole house structural design Design synergy through integration of structure with cladding and building services Fully 3D modelled prior to manufacture Vast array of structural solutions enabling architectural freedom and bespoke house designs 9

10 Unrestricted elevational treatments Brick Stone Render Cladding Tile Timber Benefits to self-builders Assured system performance Engineered to the highest level of accuracy and quality Architectural flexibility Exceptionally thermally efficient - lowering running costs Sustainable building solution - considerably less impact on the environment Greater integration and control to the construction process labour cost time quality safety 10

11 How can you make sure you get these benefits? Work only with an STA Assured manufacturer 11

12 Who are the Structural Timber Association Sets the standard for structural timber STA Assure Promotes best practice in timber construction Delivers timber building technical guidance Provides training and information Drives quality and health and safety STA Standards A guide for customers Available to download from the STA Website 12

13 Independently audited accredited member scheme for structural timber Provides confidence to customers when choosing a system manufacturer Three levels of accreditation; Gold, Silver and Bronze all levels are suitable for self build projects STA Assure Manufacturer Accreditation Levels 13

14 Structural warranty endorsement STA Assure has received formal recognition from five of the industry s leading structural warranty and building control bodies that STA Assure accredited members (Silver or Gold) meet their warranty requirements.
